WebCCTV Installation Manual

1 Introduction

WebCCTV is a unique digital video surveillance solution, which combines three major functions in one Network Video Recorder (NVR) or Digital Video Recorder (DVR): local digital recording, multiplexing and simultaneous transmission of the video via existing networks (TCP/IP). To a standard WebCCTV, up to 20 cameras can be permanently recorded while multiple operators at different locations on the network are accessing the WebCCTV device.

Being a networked device, WebCCTV utilizes two basic principles of the Internet/Intranet technology:  WebCCTV works over the TCP/IP network protocol, which provides maximum

connectivity. This means that the existing computer network infrastructure can be used eliminating extra installation expenses.

 WebCCTV uses a web-based user interface to view live images, recordings, etc.

More specific it uses Microsoft Internet Explorer.

Remote and Local Monitoring

To remotely monitor the connected cameras, the WebCCTV uses Web Browser technology. To locally monitor video, the WebCCTV also provides a local interface via a PC monitor directly connected to the WebCCTV. This local interface allows an operator to see live video from the connected cameras without the need for additional client computers on a network.

Continuous Activity-Based Recording

By default, a WebCCTV continuously records all images from all the connected cameras based on activity detection. In this case, only movement is recorded. If there is no movement, no recording takes place. If necessary, the WebCCTV can be set to record continuously.

Intelligent Storage Option

WebCCTV uses a first-in/first-out (FIFO) overwrite principle. Once the disk is full, the oldest images are overwritten.

Semi-Continuous recording (recording based on activity detection) allows a WebCCTV to store pre- and post-alarm video. Pre- and Post-alarm images are often more important than the images at the time of the alarm event itself. Up to 5 minutes of pre- and post-alarm video can be stored per event.

Version 4.4 Series

WebCCTV Installation Manual

WebCCTV makes a distinction between common activity recordings and pre/post alarm recordings. In the way that, alarm recordings have a higher storage priority and will not be overwritten by non-alarm recordings.

The WebCCTV is operational even when no live monitoring occurs. While the WebCCTV continuously records images from all the cameras, video is transmitted from the server to the client only when an Internet browser is connected to WebCCTV and someone is live-viewing images from one or more cameras.

2.2 Starting up for the first time

This chapter provides information on the following procedures:

 Turning the power on and off  Logging on to the XPe system  Desktop icons overview  Changing the password  Setting the time  Changing keyboard language  Adjust screen resolution

Connect monitor, keyboard and mouse before turning on the power and configuring WebCCTV.

2.2.1 Turning power on/off

2.2.1.1 Turning power on

To turn the power on, follow the steps below:

1. On the front side of your WebCCTV, you’ll find an On/Off button. This is a one-touch

button. When pressing it briefly, WebCCTV will begin its start-up procedure. You can verify the correct start-up sequence by checking the following:

 The fans are turning and make a humming noise.  The power indicator is illuminated.  The hard disk indicator is flashing.

2. When you have a monitor connected, you can see that:

 First it lists all the hardware components.  Second it starts loading the Windows XPe operating system

3. After about 1.5 to 2 minutes, the WebCCTV should be fully started.

The first time you turn on the power of your WebCCTV, its initial screen will be the Windows XPe logon screen.

WebCCTV does not logon automatically by default.

Version 4.4 Series

WebCCTV Installation Manual

2.2.1.2 Turning power off or restarting

Before shutting down or restarting a WebCCTV, there are some important precautions to make note of. Because a WebCCTV is constantly recording (24h) activity video on the disk, the hard disk is used very frequently. If a user shuts down the WebCCTV while it is writing to the hard disk, there is always a danger of damaging the hard disk. This may result in having an unbootable WebCCTV afterwards. There are two options:

 Restart or shutdown WebCCTV through the normal Windows interface:

1. On the taskbar at the bottom of your screen, click the Start button in the lower left

corner.

2. On the start menu, in the lower right corner, click Shut Down.

3. On the Shut Down Windows dialog box, select the Restart or Shut Down tab.

4. Click OK to shutdown or restart.

5. Wait until the WebCCTV completely has shut down before unplugging the power

cord.

 Restart or shutdown WebCCTV by using the shutdown button on the unit itself:

1. On the front of the unit there is a button to shut down the WebCCTV.

2. Because our WebCCTV is ACPI enabled, clicking this button once for a brief

moment will initiate a graceful shutdown. This is handled by the MS Windows XP embedded Operating System, because it detects the click on the shutdown button and will shutdown automatically.

3. Please be patient because it can take nearly a minute before the WebCCTV actually

shuts down completely. The WebCCTV has stopped when the green power indicator has gone out.

4. Wait until the WebCCTV completely has shut down before unplugging the power

cord.

2.2.2 Logging on to the XPe system

For access to the WebCCTV’s operating system, you have to specify a Username and Password.

The first time you turn on the power of a WebCCTV, after its boot sequence (see above) has completed, its initial screen will be the Windows XPe logon prompt:

 The default Administrative username is: Administrator  The default Administrative password is: webcctvnvr

It is highly recommended to change the Administrative password as soon as possible.

If you use an ‘AZERTY’ keyboard, this becomes zebcctvnvr. See Chapter 2.3.6 how to change this to Azerty settings.

WebCCTV Installation Manual

2.2.5 Setting time

For the WebCCTV to function properly, it is very important to use the applicable Time Zone setting. This can be done in two ways, or by the WebCCTV application configuration (See

WebCCTV User Manual Chapter 3.3.10 Time Synchronisation), or by the Windows XPe OS configuration.

We strongly advise you to use the WebCCTV application way as this is the easiest way to configure your time settings.

2.2.5.1 Through WebCCTV Web Application

Time synchronization allows you to synchronize time on all devices connected to your unit (e.g. cameras) and synchronize your server with a specific time server. This can be done by going to the Settings menu in the Video Manager Web Application and selecting the Time Synchronisation link in the top bar

Time Synchronization Screen

There are three options:



 Use video server as a (proxy) time server – The unit will synchronize with an



external time server if configured in the bottom part of the screen. If empty, the unit will act as a time server for itself and the connected devices (e.g. cameras).



 Synchronize all devices with an external time server – The unit and all the



connected devices (e.g. cameras) will be synchronized with an external time server. Configure the IP address or DNS name of the external time server in the bottom part of the screen.



 Manually configure time synchronization on each device separately (not



recommended) – No synchronization at all is performed, neither for the unit nor for the connected devices (e.g. cameras)

If your unit is part of a domain, this menu will not be available. The unit and connected devices (e.g. cameras) will be synchronized automatically with the Active Directory of the domain.

Click Apply to save the settings.

2.3.3 Assigning IP address

If you cannot use DHCP or APIPA for IP address and subnet assignment, the IP address for the Windows XPe–based client must be manually configured. The required values include the following:

 An IP address for each network adapter installed on the computer.  The Subnet mask corresponding to each network adapter's local network.

In order to facilitate remote connections to WebCCTV, it is recommended you use a static IP-address.

To manually configure an IP address, follow the steps below:

 Click Start->Settings->Control Panel.  In Control Panel, select Network and Internet Connections.  On the Network and Internet Connections sheet, select Network Connections.  In Network Connections, right-click the local area connection that you want to

modify.

 Select Properties.  On the General tab of the Properties sheet, select Internet Protocol (TCP/IP).  Click Properties.  On the General tab of the TCP/IP Properties sheet, select the Use the following IP

address option.

 Enter the IP address, subnet mask, and default gateway for the selected adapter in

their respective text boxes. The network administrator must provide these values for individual users, based on the IP addressing scheme for your site. The value in the IP Address text box identifies the IP address for this network adapter. The value in the Subnet Mask text box is used to identify the network ID for the selected network adapter. If needed, the DNS server address can be entered also.

 Click OK to save the IP addressing information.  Click OK to save the connection properties.

2.3.4 Firewall configuration

The following ports need to be opened for connections going towards the WebCCTV:

1. TCP Port 80: Web application

2. TCP Port 1518: Control connection

3. UDP Ports 4096 till 4223: Video streaming

4. TCP Port 3389: Remote Desktop connection (Optional). Frequently asked by

support when you have an issue)

5. TCP Port 5666: Q-Monitor Service.

RTP uses two UDP ports per stream (versus one in the old streaming format in versions prior to V4.0.0.0), one for RTP (the video stream itself) and one for RTCP (QoS signal stream), limiting the software to a maximum of 64 concurrent streams. This number can be limited (e.g. for security purposes) or extended using the Settings

Version 4.4 Series

WebCCTV Installation Manual

> Network settings page. In that case, Quadrox recommends you to open a number of spare ports to avoid switching issues, e.g. 4 ports extra. The first port in the range should be even.

Like all applications which communicate over networks, WebCCTV uses communication channels to pass data (commands, video, web-pages, etc …) back and forth. The network language that the WebCCTV uses is called TCP/IP. This is not a unique language but a family of related network languages, called network protocols. These TCP/IP protocols are the network protocols used on the Internet and on most networks throughout the world today. WebCCTV uses two protocols specifically: TCP and UDP.

A communication channel on a TCP/IP network can be represented as a tunnel with two endpoints. The two programs communicating with one another are each said to be at each endpoint. These endpoints are called ports.

When the two programs communicating with one another are not located on the same corporate network (like most communication between a program on a client PC and a program running on another computer on the Internet), often there is some kind of guardian device in between them. These guardian devices are called Firewalls. Their job is to guard all network communication between the corporate network and the Internet and block certain unwanted communications while allowing the desired communication to pass.

There are several levels on which a firewall can guard network communication. The most common way is to allow or disallow certain ports to be used, depending on which applications are allowed to communicate.

A firewall guards a port in a certain direction. Communication that is initiated from the Internet towards the corporate network is called incoming traffic, while communication from the corporate network towards the Internet is called outgoing traffic. Note that the initiation of the communication is important: once a connection is made, data can be transferred in both directions.

Let’s apply this principle to WebCCTV network communication. The WebCCTV client (the ActiveX component embedded in Internet Explorer at the client machine) will try to create network connections to the WebCCTV server. The eventual result of these connections will be video data streaming from the WebCCTV server to the WebCCTV client, but since the WebCCTV client initiates them, they are referred to as connections towards the WebCCTV. From the client perspective, it is outgoing traffic, while for the server it is incoming traffic.

In order for the WebCCTV to function correctly, the appropriate ports need to be opened for communication towards the WebCCTV.

There are three port configurations to perform:

1. TCP Port 80: to allow external users to see the web interface (HTTP traffic). This port

is usually opened by default.

Some ISPs block port 80. Please inform yourself.

2. TCP Port 1518: to allow external users to receive alarms, control PTZ cameras, send

commands, etc. This is called the WebCCTV control signal.

3. UDP Ports 4096 thru 4223: By default the WebCCTV uses a range of UDP ports to

transport video streams. These UDP ports are not listening all the time. The WebCCTV software enables them at random to enhance security.

Typically when the UDP ports are not opened correctly, the user only sees the webinterface but no live images.

To allow Quadrox support personnel to get remote access to the WebCCTV, TCP Port 3389 needs to be opened for Remote Desktop Connection. If the Video Server is monitored by the Quadrox Monitoring Department, TCP Port 5666 needs to be opened.

A firewall can be placed on several positions in the network. The most common place is at the edge of the corporate network, or in other words between the corporate network and the Internet. Recently it also became popular to place a firewall to protect the network traffic from a single computer. A firewall that is placed between the computer and the network is referred to as a ‘Personal Firewall’ application. In practice, a corporate network firewall is often integrated with the router connecting the LAN and the internet. For more information on routers, see the section on connecting the WebCCTV to the internet. A personal firewall is software running on the computer that it protects. Personal firewall applications can be installed separately but are also included in the Windows XP operating system (Service Pack 2) and in many virus protection software packages.

There are several scenarios where firewall configuration is necessary:

1. A user on a corporate network or at home behind a broadband router wants to access a

WebCCTV on the Internet

2. A user on the Internet wants to access a WebCCTV on a corporate network.

These situations are explained in more detail in the section on how to connect your WebCCTV to the internet. If a user on a corporate network wants to connect to a WebCCTV on another network, a logical combination of these two situations can be applied.

1. A user with a personal firewall application on his computer wants to access a

WebCCTV on the corporate network or on the Internet.

2. There is a personal firewall application installed on the WebCCTV.

Sometimes the support department will ask you to put this setting to None in order to customize your system for particular use scenarios.

Firewall

If you have a personal firewall, configure it according to section 2.4.4. The ports for outgoing connections should be opened.

A personal firewall is included in Windows XP Service Pack 2 and also in some virus scanners. Separate firewall software exists as well.

The personal firewall in Windows XP Service Pack 2 has all outgoing and necessary incoming connections open by default. No extra configuration is necessary in this case.

Internet Explorer settings

Make sure that Internet Explorer allows the installation and execution of signed ActiveX components.

1. Make sure you are logged on to Windows as an Administrator.

2. Go to the Tools Menu. Choose Internet Options.

3. Go to the Security Tab.

4. Click the Sites button, deselect the https checkbox and add your WebCCTV to the

trusted sites list. Click OK.

5. Click the Custom level button at the bottom.

6. Set the following options to ‘enable’ or ‘prompt’:

7. Download signed ActiveX controls (prompt)

8. Run ActiveX controls and plug-ins (enable)

9. Script ActiveX controls marked as safe (enable)

Adding your WebCCTV to the trusted sites is required to guarantee that all necessary communication can be established with the WebCCTV server!

2.3.6.2 Router and firewall

To fully understand this section it is important to know what the difference between a router and a firewall is.

A firewall is the piece of software that takes care of guarding the network communications. Sometimes the term ‘firewall’ refers to the machine performing firewall tasks. This is confusing and in fact incorrect: normally a firewall is not a piece of hardware, but a program running on that hardware.

A router is a piece of hardware that embodies the physical connection between two different networks (e.g. your local network and the Internet). It redirects (“routes”) data so that it arrives at the correct place. A router is a hardware device, but its functionality is controlled by software that runs on the router.

Sometimes the routing functionality is provided by a proxy server, bridge or gateway. While these are not the same as routers, they can be considered as such for the discussion in this document.

Router software can have firewall capabilities. In other words, the router software can have, apart from its normal capability to connect two networks and redirect data, the capabilities of inspecting, allowing, and denying certain network communication. As an example, most broadband routers (ADSL, SDSL, cable modems, etc) nowadays have firewall capabilities and are also being used as such. In the following schemes the firewall and the router are depicted as two different entities (nodes on the network), but know that they could be one and the same node in practical cases.

2.3.6.2.1 Configuring router

The router that forms the connection between the corporate network and the Internet needs to know which internal machine it has to send network traffic to. For example, a client machine on the internet requests a connection on port 1518 (the port for WebCCTV video commands), using the public IP address of the router. The router then needs to know to which device on the corporate network it needs to send this connection request, in this case the WebCCTV. So the router needs to know the local IP address on the corporate network of the WebCCTV. Configurations for different brands and models of routers in the field can be found in:

Web Resource for Router Configuration and Setup: http://www.portforward.com/routers.htm

Networking Tips: http://www.portforward.com/network.htm

If you don’t already have a router you will need to purchase one and configure it as part of you network.
