While IP cameras are often more expensive than their analogue counterparts on a one-to-one basis there is often no need to rip out analogue cameras if they still have life in them. Most analogue cameras can be migrated to IP through the use of encoders; and indeed this is as a key foundation stone for the UK CCTV strategy over the next few years to avoid unnecessary cost. Encoders can be deployed at the camera (network edge) or in the Control room. Once you have encoders in place you can also start to add additional functionality to your system with the use of video analytics, which over the past couple of years have proven to offer demonstrable benefits; or driving additional services such as audio for announcements and commands, or connecting other equipment such as PIR’s / Redwalls or opening and closing barriers.
System integrators and end-users who wish to see the benefits of an IP-based solution should look to someone who really knows the technology and can give an impartial view. It is common sense that manufacturers will only support their own hardware and will promise the earth for it, whereas a distributor will have evaluated a number of solutions from different vendors and be able to say that product A is the best for solution B because of XYZ whereas product Y is the best for solution C because of etc etc.
