IP Surveillance Networking is the single most important aspect of setting up an IP surveillance system. Careful consideration to all the fundamentals like required throughput, LAN segmentation, QoS, Uptime play a crucial role. If you know nothing about networking we suggest you seek out an experienced network engineer to develop a system to suit your needs so you dont lose data. However if you are prepared to get your hands dirty we suggest you read on as we attempt to demystify a complex and difficult topic.
Networking consists of two parts, the hardware that you use and the protocols and software that utilise it. You may already have a network of computers, that use a switch or hub to communicate with each other, this is the exact same network setup that you will use to run your surveillance equipment. This is because your computers and cameras are sending ones and zeros of information, either a file, or a video, across the network to be used by the end user anyway they choose.
this consists of all the physical parts of the network.
Network switches allow devices such as network cameras, servers and PCs to communicate with each other to share information and, in some cases, a common Internet connection. Network designs can take many forms and may vary in terms of performance and security. First, determine what your company is using the network for and how congested your local area network (LAN) or wide area network (WAN) is. If you are implementing a smaller surveillance system involving 8 to 10 cameras, you should be able to use a basic 100-megabit (Mbit) network switch without having to consider bandwidth limitations. Most companies can implement a surveillance system of this size using their existing network.If you are implementing 10 cameras or more, you should try to estimate the load on the network using a few rules of thumb: A camera will use approx. 2 to 3 megabits of bandwidth when configured to deliver high-quality images at high frame rates. With more than 12 to 15 cameras, you should consider using a switch with a gigabit (Gbit) backbone. If a gigabit-supporting switch is used, the server that runs the video management software should have a gigabit network adapter installed.Determine the pattern of congestion levels over a given period to find out if you have to install additional bandwidth capacity on your network or whether you can make use of the same network as for general business activities. It may be that the network traffic drops off during nighttime and weekends—the times when you may want to activate the video surveillance system. The usage pattern will help you to determine whether you can a) simply use the same network infrastructure for your general purpose needs as for your surveillance needs, or b) use a combination of existing general purpose network as well as a new network for IP-Surveillance. If additional network capacity is needed, new cabling is normally not needed since adding a switch or reconfiguring the patch panel may solve the problem.
