Please note that this „scheduler“ only applies to the host specified in the Alarm hosts list. Additionally, there is no connection to the calendar function for video recording.

! In the Alarm hosts list, select the host for

which you would like to set the calendar (A).

! Click on the Scheduler button (B).

All areas in the weekly plan which are shown as light colored are active areas (pre- set). This means that within this time area all selected messages will be sent to the corresponding alarm host

! Click on the active button. ! While you are in the weekly plan, click once with the right mouse

button. The area will now appear dark (see Diagram. 7-10). Dark areas are inactive time areas.

The smallest time unit you can set is 15 minutes.

7.3 SeMSy Configuration

The acronym SeMSy stands for Session Management System and refers to the connection of a management system to one or more DIS units.

The SeMSy configuration (see Diagram. 7-24) dialog box deals with rights allocation for access from a higher ranking computer (management system).

With the Encoder for SeMSy available rights allocation, you can retrieve coded image data from the respective DIS and transfer these to another DIS via a management system.

With the Decoder for SeMSy available rights allocation, you can read coded image data from another DIS into the respective DIS and decode them via the management system.

The following block diagram shows the signal path in the DIS and the signal transfer from and to a management system in simplified format.

The analog video signal is first digitalized in the encoder and transferred to the decoder. During a recording, the data coming from the encoder are saved on the hard disk and can be read out again via the decoder during playback. The decoder converts the digital signal back into an analog signal for viewing on the monitor.

To access the SeMSy configuration dialog box, go to

Common settings > SeMSy configuration

Once you have activated Encoder for SeMSy available in the SeMSy configuration dialog box, the coded data can be transferred over the network by the management system. Here you can now specify to which other DIS this coded signal is to be transferred and decoded for viewing on a monitor. At this „receiving DIS“, Decoder for SeMSy available must be activated in the SeMSy configuration, as this otherwise will reject access to the decoder. If a DIS is to transmit coded data as well as receive and decode data, both rights need to be activated.

In the above example, images can be retrieved from DIS no. 1 and 3 and read in at DIS no. 2 and 3.

7.4 Video Streaming

Video Streaming involves settings for the DIS as a receiver (client) and/or a transmitter (server) for video data packets transported using the

multicasting method.

7.4.1 What does multicasting mean?

Multicasting refers to transmission technology used in a computer network, whereby a message is sent from one point to several destinations in a group. Multicasting also is known as multi-point connecting. The advantage of multicasting is that messages can be sent to multiple participants or closed participant groups at the same time

A general distinction is made between three connection types: Point to point connection: Here, the transmitter (server) and the

receiver (client) each have a unique IP address.

Multicasting: The transmitter (server) sends its data to

a group of receivers (clients).

Broadcasting: The transmitter (server) sends its data to

all receivers (clients) in the network.

Y our DIS can transmit as well as receive dat a (video streams). The settings for this are made in the Video Streaming dialog box.

7.4.2 Multicast settings

! Open the „Video Streaming“ dialog box by

clicking the Video Streaming selection.

Diagram. 7-26

Dallmeier electronic GmbH & Co.KG

Configuring the DIS as a server

In the Server tab, specify if your DIS is to function as a multicast streaming server and if so, which mode should be used. In Mode = OFF, your DIS does not function as a multicast streaming server.

Mode: MPEG Multicast

The DIS records while sending all video streams to the network.

If the DIS is set to record sound as well, this also is sent to the network as an audio signal.

Mode: RTP/MPV Multicast

The DIS records while sending all video streams to the network.

In addition to data in MPEG format, header information is sent. This information makes it easier for the client to synchronize the data packets.

Even if the DIS records sound to accompany the picture, the audio signal is not sent to the network in this mode.

RTP implementation in the DIS is based on the following standards: RFC3550 (RTP transport protocol for real-time applications)

RFC3551 (RTP profile for audio and video conferences with minimal control) RFC2250 (RTP payload format for MPEG1/MPEG2 video)

This allows the stream to be received by each device compatible with these standards.

Multicast IP address

The multicast IP address is not to be confused with the IP address of a point-to-point connection. Transmitted video streams are identified via the multicast IP address and the port, giving the client information as to the sender of the data packets

Diagram. 7-27

DIS-1/S and DIS-1/L

Dallmeier electronic GmbH & Co.KG

Packet size

The size of the data packets to be sent is set in „Packet size“. To optimize the transmission times (delay) of the data packets, the packet size should be set to 2,048 bytes. The larger a packet’s size, the more time it can take until the packet is „complete“ and ready for transmission. This can lead to a delay that results in a „jumpy“ video stream. The smaller the data packets are, the greater the network overhead.

Configuring the DIS as a client

In order to receive DIS video streams from a DIS configured as a server, you will need to set your DIS to act as a client. To do this, click the Client tab.

Mode

Here you can set the mode with which the transmitter (server) sends the data packets.

Currently, the DIS can receive only

MPEG multicast streams.

Multicast IP address and port

Enter the address and port of the DIS from which you would like to receive the video streams.

As your DIS can be simultaneously configured as a server and a client, you must ensure that your DIS’s multicast IP address for client operation is not identical to that used for server operation. If the same address is used, your DIS would receive its own

Diagram. 7-28

Dallmeier electronic GmbH & Co.KG

Diagram. 7-29

Configuring a server using the DaVid protocol

The DaVid protocol can be used to configure several multicast servers on a DIS. The single DIS then functions as multiple DIS systems set up as a server. As such, the DIS sends different video streams across the network.

Servers configured using the DaVid protocol are independent of the settings made on the Server tab. Transmission continues to be made over these „DaVid servers“ even when you set the Mode on the server tab to OFF.

These servers are configured e.g. from a central control PC via the DaVid protocol and changed as needed.

The list of configured servers is stored on the DIS and remains intact after a reboot.

Refer to the Server tab (DaVid) to see which servers are stored.

If changes were made, click the Update button to update the list.

Click Remove to delete all entries in the list.

If your DIS is removed from a network and integrated into another network without clients, all servers currently in the list should be removed. If this is not done, the DIS would continue to transmit in the new network environment and place an unnecessary burden on network resources. This especially should be taken into account in the event of a repair, when the control PC no longer is accessible for the DaVid protocol. Only via the control PC can transmission without removing the list be suppressed.

8 Configuration

8.1 Selecting record mode

Click the Track menu entry to enter the Track settings dialog box. The number of configurable tracks is a function of the number of hard disks installed in the system (see 8.1.1, Creating tracks).

DIS-1/S Standard 1 HDD Available tracks = 1 DIS-1/S Maximum 2 HDD Available tracks = 2

DIS-1/L S tandard 1 HDD Available tracks = 1 DIS-1/L Maximum 4 HDD Available tracks = 4

8.1.1 Creating tracks

When two or more hard disks are installed, each hard disk is equivalent to one partition. In OEM state, a single track (track 1) is assigned to all partitions (hard disks).

If you would like to record only on one track, the following settings for creating tracks are not necessary.

Attention

All previously recorded pictures will be automatically erased if a track is reassigned or if several tracks are configured.

Diagram. 8-1

Diagram. 8-2

8.1.2 Setting options

Click the Encoder settings tab to specify the settings for the respective track.

T rack:

The encoder settings apply jointly for all the created tracks.

Track selection has no relevance, therefore, for the encoder setting.

Input:

Here you can select which encoder you would like to use for digitalization. „Encoder 1“ is set by default for DIS-1/S and DIS-1/L.

Bit rate:

The bit rate is a measure of the degree of compression of video data; it thus has a direct impact on the picture quality of the recording. A low bit rate stands for a high degree of compression with a relatively small volume of data but poor picture quality. A high bit rate stands for a low degree of compression with a relatively large volume of data and very good picture quality. A bit rate of between 4 and 6 Mbps (megabit per second) is a good compromise between data volume and picture quality. Most requirements in surveillance systems are met with the quality of picture thus obtained.

GOP Value:

GOP (Group Of Pictures) is a variable for specifying how pictures are used to generate the MPEG-2 data flow. A GOP value of 6 and 15 enables good picture quality with high compression. A GOP value of 1 denotes a low compression factor and should only be used for special applications (e.g. multiplex mode).

Dallmeier electronic GmbH & Co.KG

Extended GOPs

GOP sizes 18, 21, 24, 27 and 30 only can be set if the checkbox located next to the extended GOPs option is ticked. Please, however, note that reverse playback is only possible in reduced quality (frame drops) when these GOP sizes are used.

Pictures/second:

The picture rate is set by default for a real-time recording with 25 pictures per second and cannot be changed. In special cases it is possible to order a software update that can be used to set lower picture rates.

Please note that an audio recording and its setting in the Audio bit rate box (see next item) is only possible with 25 pictures per second.

Audio bit rate:

The audio bit rate setting allows you not only to control the audio quality , but also the amount of required hard disk space to a certain extent. The higher the audio bit rate, the better the audio quality. A higher bit rate, however, requires more hard disk space than a lower bit rate. The following bit rates (in Kbits) can be set: 128, 160, 192, 224, 256 and

384.

Bit rate mode:

The bit rate mode allows you to configure video recording to occur at a constant or a variable bit rate. A variable bit rate makes better use of the available hard disk space. The variable setting changes the bit rate in accordance with the activity (changes) in the picture. You can limit the fluctuation of the bit rate by making the appropriate setting, which is done as a percent.

Diagram. 8-7

DIS-1/S and DIS-1/L

Dallmeier electronic GmbH & Co.KG

Example to bit rate mode:

With a set bit rate of 4 Mbits and a bit rate mode „variable by 50 %“, the bit rate can vary from 6 Mbits to 2 Mbits during recording. In variable bit rate mode, settings are made in 10 % increments, from 10 % to 400 %. Settings are not adopted and put into force until you have clicked on OK.

If you change the bit rate after already making recordings, a message is issued before the change is adopted warning you that all the pictures recorded on this track will be deleted.

Your changes are not adopted until you answer this safety prompt with Yes. If you answer No, you will remain in the Track settings dialog.

8.1.3 Deleting a track

To completely delete the recordings on a track, click on the Delete button in the Track settings dialog.

When the Delete button is clicked once, the recorded pictures as well as the track definition are deleted.

The recordings will not be deleted until you have answered the security prompt with Yes.

8.2.4 Contact Start / Stop

With the setting Contact Start / Stop, recording is started with one contact and stopped with another contact.

It is also possible to perform the starting and stopping with only one contact. Depending on the type of contact (break or make) you must invert one of the two signals (mark the checkbox Invert signal !).

Recording then runs when the contact is pressed, and stops again when you release the contact.

Settings

! Open the tab Contact start/stop. ! In the Start contact box, select the contact

for starting recording.

! In the Stop contact box, select the contact

for stopping contact.

Please check the contact assignment of Contact IN in the appendix.

8.2.6 Motion detection

In motion-dependent recording, pictures are only shown whenever there is a change in the picture.

Motion detection is only possible when the GOP value is set to 6 or higher (see 8.1.2). If the set GOP value is smaller than 6, the picture data for motion detection no longer are sufficient.

In order for you to be able to configure the settings for motion detection and have the system record according to this configuration, the

active checkbox (A) must be ticked.

Settings

! Open the tab motion detection. ! Mark the active checkbox. . ! To set the threshold value and timeout,

please refer to the following explanations.

Setting the threshold value

The threshold value specifies how much the image content needs to change in order for a recording to start. Field B (see Diagram. 8-17) shows you the current values of the changes in the live image and provides you the basis for setting the threshold.

If you set the value of the threshold above the current value of the changes, no recording occurs.

If the set threshold value is above the current value, recording occurs.

A symbol on the upper left part of the screen indicates whether a recording is being made or not.

Diagram. 8-16

Diagram. 8-17

Diagram. 8-18

Recording

Dallmeier electronic GmbH & Co.KG

In order to have a better overview of the live picture you should switch at least some of the menu to transparent before you set the threshold value. To do this, click with the right mouse button on the blue headline in the dialog box Recording settings. Clicking again with the right mouse button will reverse the transparency again.

Setting the timeout

The timeout, which is set in seconds, determines the recording duration after an event has exceeded the set threshold value and prompted a recording.

If the timeout is set to 10 seconds, for example, and only one triggering event occurs, recording is stopped after 10 seconds. If another triggering event occurs within the 10 seconds, recording continues for an additional 10 seconds from this time.

Within a continuous recording, individual events captured in the event recording (see 8.2.7) are evaluated as a single event and only one marker is set.

8.2.7 Configuring markers for events

In order to simplify a picture search in playback mode (see chapter 9.1), you can record markers for the pictures

You can specify when you want a marker to be recorded by marking the checkbox in question.

In the example on the left, a marker is always recorded when contact 1 and/or contact 2 are actuated („on“) and when contact 3 and/or contact 4 are opened again („off“). With Motion event recording, a marker is set for each motion event.

If the checkbox for Recording start is marked, a marker will be recorded regardless of other settings each time a recording is started.

Notification to alarm host

If a motion-triggered recording start is to be notified to an alarm host, the corresponding checkbox in the notification list for the alarm host must be activated (see chapter 7.2.1 for more information).

Manually setting markers

In addition to internally triggered markers (e.g. contact or motion), a marker can be externally set.

Markers only can be set using the DaVid protocol and a control PC.

Diagram. 8-21

Dallmeier electronic GmbH & Co.KG

Diagram. 8-22

A marker is practical, for example, if a situation that is to be evaluated later on occurs when viewing a live picture. Once the marker has been set, it is easier to locate the section in question using the picture searching function. To make use of this function, click the checkbox next to Set marker.

8.2.8 Recording „Off“

Setting the record mode to Off and confirming the setting (by clicking on OK) stops the recording.

A white square appears in the top left corner of the screen to indicate that recording has stopped.

9.1.1 Fading out the menu bar

While the function you have selected is being performed, the menu bar can be faded out.

! Click once inside the display window with

the right mouse button. In the top left corner (A) you can see the

current playback mode. In this example it is slow forward at a speed of 1/4 x.

In the bottom right corner (B) you can see the date and time of the recording.

! Click again with the right mouse button and

the menu bar will return to view.

When the menu bar is hidden, one could assume that they are in live mode. Configured settings then could be accessed without any trouble at all. The date and time have been programmed to appear differently in order to determine if you currently are in configuration/playback or in live mode

If only the menu bar is hidden, the characters appear in black against a colored background (Fig. 9-7). Access to the configuration menus is possible without entering a password.

If the configuration/playback mode was exited by clicking on Exit, the characters appear in white against a black background (Fig. 9-8). Access to the configuration menus only can be granted by entering a password.

9.2 Search functions

Two types of search function are available to find specific pictures:

Fast search with slide controller Direct picture search

9.2.1 Fast search with slide controller

! Click once on the Controller On/Off button

! Move the cursor onto the controller (D).

With the left mouse button kept pressed you can move quickly through the picture sequence to a specific point of the recording.

! Click once again on the Controller On/Off

button (C) to fade out the slide controller.

Changing the time area for a quick search

When using the sliding bar in playback mode, the entire hard disk area is scanned (from the first to the last picture) in most cases. Even minimal movements of the sliding bar translate into large time gaps when utilizing the entire area.

You can adjust the area to be controlled by following the steps described below.

Diagram. 9-9

Dallmeier electronic GmbH & Co.KG

! Click on the sliding bar (A) with the right

mouse button. Another, vertically positioned sliding bar appears (Diagram. 9-

11).

! Click on this sliding bar with the left

mouse button and move it upwards to limit the search area of the quick search sliding bar.

This can seen by the bar below the sliding bar becoming smaller (Diagram. 9-12, B).

Now only a specific area of the track will be scanned, not the entire track.

When the quick search sliding bar is positioned between both end points (first picture - last picture), these points will refer to the search area that is now smaller .

This smaller area can be moved within the track in order to select an appropriate time period from the track as a whole.

! Click on the bar displaying the sector

(Diagram. 9-13, C) and move it to the area in which you are interested.

Picture search by date and time

! Click on the Search button (D). ! In the Search dialog window under the Date/

Time tab, enter the required date and time by clicking on the corresponding arrow buttons.

! Now click on the Search button (E) to see

the picture recorded at this particular moment in time.

Picture search by event

Picture search by event is highly effective particularly with contactcontrolled recordings.

! Open the tab Events.

The list shows the events that have occurred. Please note that only those events are listed

which were selected in the Event recording menu (see chapter 8.1.7).

! Click twice on a listed event to see the

picture recorded at this particular moment in time.

With one press on the left or right arrow button you can jump to the previous or following event respectively.

Starting point is always the event (picture) in view on the monitor and not the position within the events list.

We recommend therefore that you first select an event in the events list and have it shown on the monitor. From here you can now select earlier or later events as required.

Diagram. 9-14

Diagram. 9-15

To obtain a better view of the picture you can change the position of the menu and have it partly shown on a transparent background.

! Click with the left mouse button on the upper

bar of the menu and keep the button pressed. You can now drag the menu to a new position, e.g. to the bottom of the picture.

! Click with the right mouse button in the same

area to partly show the menu on a transparent background.

Picture search in intervals

You can also search for specific pictures by moving backwards and forwards through your recording in defined steps.

Steps can be taken in: Days – Hours – Minutes – Seconds.

The size of the step is set in the Interval box. Following entries are possible: 1, 5, 10 and 30.

For example, an interval setting of 10 signifies an absolute step size of 10 days, 10 hours, 10 minutes or 10 seconds.

Starting point for the steps in forward or reverse direction is the picture visible on the monitor prior to triggering the interval search.

Here, too, it is possible to move the menu to a different position and/or have it partly shown on a transparent background.

A 4 What is MPEG?

This section provides a brief introduction to the compression method called MPEG. We have intentionally kept the explanations simple and refrained from considering complex algorithms.

Picture compression

Anyone who has saved pictures on his or her computer will know the various types of file in use and their corresponding sizes. When a picture is saved as a bitmap file, for example, all the pixels in the picture are saved. The volume of data involved is accordingly large. For instance, the following picture with the dimensions 140 x 90 mm and a resolution of 150 dpi (dots per inch) would require approximately 3 MB of memory. Various compression methods are used to reduce the volume of data. To obtain a general idea of how this works let’s consider the JPEG method.

Picture saved as a bitmap file without compression.

JPEG compression

Probably the best known compression technique is JPEG (Joint Picture Expert Group). With JPEG the entire picture is evaluated and redundant (i.e. similar and interchangeable) pixels are grouped in blocks. The higher the degree of compression, the more pixels are grouped in a block. At a high level of compression the creation of blocks has a negative effect on picture quality, with the blocks (artifacts) becoming clearly visible in the picture. JPEG compression always entails a loss of data, hence it is impossible to restore the picture to its original condition.

Dallmeier electronic GmbH & Co.KG

Picture after minor JPEG compression with high quality: 440 KB

Picture after major JPEG compression with poor quality: 26 KB

In the full view you hardly notice any change at first glance. In a close-up detail view, on the other hand, the artifacts are clear to see. Therefore, the most important thing to consider when selecting the degree of compression is the size in which the picture is to be viewed or printed.

The JPEG compression technique is suitable for single pictures but not for video sequences. An adaptation of the JPEG compression method for video sequences is available under the name M-JPEG.

Data compression is essential particularly for video recordings. Without compression, a 90-minute film with 25 pictures per second would require approx. 120 GB of memory.

M-JPEG compression

With M-JPEG (Motion-JPEG), each individual picture of the video sequence is compressed in accordance with the JPEG technique. This is particularly good for exact imaging because each single picture is present in full. However, the amount of memory required is still relatively high.

DIS-1/S and DIS-1/L

Dallmeier electronic GmbH & Co.KG

MPEG compression

MPEG stands for „Motion Pictures Expert Group“ and is now divided into the standards MPEG-1, MPEG-2 and MPEG-4. MPEG-3 was integrated in the MPEG-2 standard and is therefore no longer found as an independent standard.

Unlike M-JPEG , the MPEG method does not compress each individual picture but only, for example, every 12th individual picture. These individual pictures are called intra-frames (I-frames). The pictures between these I-frames are not transmitted in full – only the changes between the I-frames are transmitted.

Between the two I-frames in this extremely simplified example is one picture containing a change from the preceding I-frame. This severely reduced picture is called a P-frame (P stands for Predicted). Severe distortions in a picture’s contents may arise when there is only one P-frame between two I-frames. This is combated by placing so-called B- frames (B stands for bidirectional) between I-frames and P-frames. Bframes draw their information contents through referencing with the pictures which are transmitted both beforehand and afterwards. These pictures can be I-frames or P-frames. B-frames are also known as “bidirectional referencing frames”. A sequence of I, P and B-frames is called a GOP (Group of Pictures).

The following diagram shows the relationship between the various frames. P-frames always have preceding I-frames or P-frames as reference, whereas B-frames use both preceding and follow-up I-frames or P-frames.

I-Frame 1

I-Frame 2

P-Frame

Dallmeier electronic GmbH & Co.KG

GOP size

The GOP size denotes the number of I, P and B-frames. GOPs may contain only one I-frame or one group of I, P and B-frames. The MPEG standard permits GOPs of random length and composition, with a GOP always commencing with an I-frame (key picture). However, maximum GOP lengths are laid down in order to guarantee good coding results by an encoder. The maximum length for NTSC is 18 frames and PAL 15 frames. The order within this limit is variable and can be directly influenced to improve the picture quality depending on the original (camera viewing angle, frequency of movement etc.). When there is a general change of picture – such as happens, for example, when switching over from one camera to another – it is impossible to compare the last frame of camera 1 with the first frame of camera 2; consequently, it is recommended to refrain from using large GOP sizes particularly in multiplex mode.

Advantage of MPEG-2 over MPEG-1

MPEG-1 provides roughly the same standard of quality as VHS. It was originally created for data transmission rates of 1.4 MBit/s, which is approximately the data flow from a CD-ROM at single speed. The fact that the data flow is also constant is a disadvantage when there are major changes in the picture as these require more data.

MPEG-2 is regarded as the standard for digital TV studio quality with a variable data rate of typically 1 to 16 Mbps. Lower bit rates (500 kbps) or higher bit rates (e.g. in studio systems) are also permitted however.
