2) Network

The network camera supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and at least one version must always be enabled. When using IPv4, the IP address for the network camera can be set automatically via DHCP, or a static IP address can be set manually. If IPv6 is enabled, the network camera receives an IP address according to the configuration in the network router. There is also the option of using the Internet Dynamic DNS Service. For more information on setting the Network, please see Setup> System>Security>Network.

•

Obtain IP address via DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol

that lets network administrators centrally manage and automate the assignment of IP addresses on a network. DHCP is enabled by default. Although a DHCP server is mostly used to set an IP address dynamically, it is also possible to use it to set a static, known IP address for a particular MAC address.

• Use the following IP address - To use a static IP address for the Network Camera, check the radio button and then make the following settings:

- IP address: Specify a unique IP address for your Network Camera.

- Subnet mask: Specify the mask for the subnet the Network Camera is located on.

- Default router: Specify the IP address of the default router (gateway) used for connecting devices attached to different networks and network segments.

Notes:

1. If DHCP is used, Speco’s free DDNS service can be utilized. In the camera’s page in the web

browser, go to Settings/Network/DDNS to set it up.

2. The ARP/Ping service is automatically disabled two minutes after the unit is started, or as soon as an IP address is set.

3. Pinging the unit is still possible when this service is disabled.

3) Video & Image

•

Stream1 Setting

- Codec: The codec settings are separated into MPEG4 and H.264.

H.264 is also known as MPEG-4 Part 10. This is the new generation compression standard for digital video. This function offers higher video resolution than Motion JPEG or MPEG-4 at the same bit rate and bandwidth, or the same quality video at a lower bit rate.

There are 4 pre-programmed stream profiles available for quick set-up. Choose the form of video encoding you wish to use from the drop-down list:

* H.264 HP(High Profile): The primary profile for broadcast and disc storage applications,

particularly for high-definition television applications (for example, this is the profile adopted by the Blu-ray Disc storage format and the DVB HDTV broadcast service).

* H.264 MP(Main Profile):

Primarily f used rarely in videoconferencing and mobile applications, it does add additional error resilience tools to the Constrained Baseline Profile. The importance of this profile is fading after the Constrained Baseline Profile has been defined.

* H.264 BP(Baseline Profile):

or low-cost applications that requires additional error robustness, this profile is

Originally intended as the mainstream consumer profile for broadcast and storage applications, the importance of this profile faded when the High profile was developed for those applications.

* MPEG4 SP(Simple Profile):

Mostly aimed for use in situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth, device size etc.

- Resolution:

It enables users to determine a basic screen size when having an access through the Web Browser or PC program. The screen size control comes in different modes like 2048x1536, 1920x1080, 1280x1024, 1280x720, 704x480(576), 640x480, 352x240(288), and 320x240. Users can reset the selected screen size anytime while monitoring the screen on a real-time basis.

- Bitrate control:

The bit rate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image complexity, using up bandwidth for increased activity in the image, and less for lower activity in the monitored area.

CBR allows you to set a fixed target bitrate that consumes a predictable amoun t of bandwidth. As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame rate and image quality are affected negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit rate needs to be increased. Not setting a priority means the frame rat e and image quality are equally affected.

- Bitrate:

When it is necessary to adjust a smooth transmission status according to network situations,

users can increase the compressibility to carry out the network transmission stably. On the other hand, when it is necessary to maintain a detailed monitoring screen by enhancing the image quality, users can do so by decreasing the compressibility. In ease case, please adjust this function according to the network status and monitoring purposes. The default is 2000(Kbps).

- Frame rate:

Upon the real-time play, users should select a frame refresh rate per second. If the rate is high, the image will become smooth. On the other hand, if the rate is low, the image will not be natural but it can reduce a network load.

- GOP size:

Select the GOP(Group of Picture) size. If users want to have a high quality of fast image one by one, please decrease the value. For the purpose of general monitoring, please do not change a basic value. Such act may cause a problem to the system performance. For the details of GOP setting, please contact the service center.

• Stream2 Setting

Sometimes the image size is large due to low light or complex scenery. Adjusting the frame rate and quality helps to control the bandwidth and storage used by the Motion JPEG video stream in these situations. Limiting the frame rate and quality optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage, the Resolution, Frame rate, and Frame Quality should be set to an optimal value.
