IP and Megapixel cameras and POE infrastructures are starting to replace the traditional analogue coaxial based cameras both for single camera applications as well as multiple camera multiple site applications. However, there are a number of misconceptions about IP systems and infra-structure that deserve some discussion. IP Cameras are designed to put video out directly onto networks, rather than out a traditional coaxial or twisted pair cable. Traditional cameras can also be converted to IP transmission by inserting a video encoder onto the network. IP transmission allows a maximum cable length of 100 metres on Cat 5 or 6 cable, so IP cameras located more than 100 metres from the nearest switch or hub must have some form of in-line booster installed. IP cameras also usually transmit their video using either MPEG-4, Motion JPEG or H.264 so it is important to check with your recording supplier to make sure the camera is supported by your DVR. Power Over Ethernet (POE) is a networking technology that allows the LAN infrastructure to power the edge camera or other device without having to run additional 230 volt or ELV cabling. This has major advantages when security installations are piggybacking onto existing LAN cabling. Each POE switch is rated for a maximum current draw which must be carefully calculated when planning a POE deployment. Click here to go to our Veracity infra-structure page. Megapixel cameras are a subset of IP cameras that use handycam technologies to transmit picture resolutions that are multiples of the resolutions possible with traditional analogue cameras. This allows users to zoom in on details within the picture to a level that would not be possible with traditional cameras. Click here to download brochures on our 3 and 5 Megapixel Arecont cameras. There are also a number of specialist megapixel cameras that allow 180 and 360 degree simultaneous views. This allows clients with public spaces to have 100% space coverage which has many advantages both for security and health and safety reasons.
