How to Deploy an IP-Based CCTV System
IP-based systems, unlike analog CCTV systems, utilize the existing IP infrastructure. Being digital also means they are inexpensive and easy to install. IP-based CCTV systems can connect directly to IP networks like the Internet, allowing a system to be monitored and managed on the Internet using any standard browser. Data can also easily be encrypted and stored, using already existing systems and infrastructure. Being standard-based makes it possible to integrate the system with multi-vendor solutions as well.

1
Select an IP-based camera. Common IP cameras include Pelco, Mobotix and the D-Link DSC series of cameras. Ensure that they have either Wi-Fi, wired Ethernet or both features to allow you flexibility in setting the cameras up depending on the location and need of the network.
-
2
Position the camera and set it up by plugging into a power outlet and into an Ethernet jack as well. If you need to use it in Wi-Fi mode, ensure the Ethernet cable is unplugged and the camera is positioned within range of your wireless router.

Turn on the computer and wait a few seconds for the camera to be detected. Once it is found, insert the installation CD that came with the camera, and run the install wizard. Once it has been given an IP-address by the router, it will be discovered every time as long as it is within range of your router.

4
Set up as many cameras as you want using the same procedure above for each camera. Ensure that you don't exceed the number of cameras the surveillance application can handle at any particular time.

Tips & Warnings
For high-quality feeds and resolution, ensure that your network supports speeds above 56 megabytes per second (mbps).
The more cameras you have, the higher the network speeds should be. You can also consider implementing quality of Service (QoS) mechanisms that will offer the desired video quality. For best resolution, use wired networks.
Where you need to deploy a large number of cameras in the 100--1000 range, consider using a 10-gigabit Ethernet network. Remember also not to fully utilize the network bandwidth as this will impact on other network applications.
Where local power outlets are not available, consider using Power over Ethernet (PoE) switches and adapters, which route power over Ethernet cables.
You can set up the cameras for motion-detection, event triggers and alert automation via either e-mail or a phone call, using the vendor software that comes with most camera setups.
