When using an external POE switch all of your CAT5 or CAT6 will run directly from each camera to a POE switch that is connected to your local network. Some NVRs come with built in POE, but in most cases it is recommended to use an external POE switch like the POE-8MB1G from Securit圜.

In most cases you run your video and power to and from the camera on the same CAT5 or CAT6 wire, assuming you are using a POE (Power Over Ethernet) power source such as a POE injector or POE Switch.

IP cameras use digital video transmission over CAT5 or CAT6 cable. The power wires can be split off from the coax in cases where your power source may not be in a close proximity to your recording device. Siamese Cable is a manufactured coax cable with a set of power wires attached to it. You could run a coax wire and separate power wires but most CCTV professionals choose to use “ Siamese Cable”. One for video transmission and a set of power wires in order to power the camera. When installing a completely new security system you may want to have the video and power wires come from a single location located near the storage device (DVR or NVR) as shown below.Īnalog, HD-SDI and HD-CVI cameras will need two wires run to them. That being said, we will be talking about a fully-wired system in conjunction with a storage device such as a DVR (Digital Video Recorder) or NVR (Network Video Recorder). I do want to mention that it is possible to reliably transmit video wirelessly using a device such as the TP-LocoM5 – Wireless Access Point/Bridge as seen here at But even then you would still need to have a power wire run to the camera or a local power source near the camera and it only works with IP Cameras. Most CCTV professionals would probably not recommend a wireless system in an environment where up-time and security are critical. Yes, there are some “Wireless Security Camera” solutions available on the market today, but if you do some research you will find that there are a lot of limitations to wireless security cameras. One thing all of these options have in common is you will probably have to run some sort wire to the cameras. You may decide to go with a traditional analog system, HD-SDI, HD-CVI or even an IP network based security products. Today there are a lot of options when it comes to choosing a quality CCTV security system.
