Using CAT5 Cable to Wire Analog CCTV Cameras to a DVR 2

Video baluns being invented can mean that CAT5 cable is used to connect CCTV cameras to a CCTV DVR. The connections can be made using screwdrivers. There is no need for specific tools or different. For CCTV installation, you can either use RG59 or the CAT5 (Unshielded Twisted Pair). Comparing it with the coaxial cable, the UTP can be less expensive and works with the video baluns to extend the video transmission distance. One of the CAT5 cables can have four pairs of UTP. It transmits video, an RS485 control signal, and audio. It does this while supplying power supplies to analog cameras with one CAT5 cable. CAT5 is also called the Ethernet cable. It can connect IP devices. CAT5 can make it easy to send upgrades to your system with new cameras. Here are some things to know when you wire your new system.

What Do I Need For Wiring?

The videos can transmit along the CAT5 cable by using pairs of video baluns. There is one at the camera end and one at the DVR end. There can be two different types of video baluns, standard definition, and high definition. They were designed to be used with their retrospective DVRs. Power can be sent by using screws in sockets and DC plugs. the socket goes at the DVR end and the plug goes at the camera end, and put the camera power close to the DVR.

The Correct Cables

Use pure copper CAT5 cable. Sometimes CAT5 cables are not pure copper but copper-coated aluminum or CCA. Check the labels when you buy the cables to make sure the cable is 100 percent copper. CAT5, CAT6, CAT5e, and CAT6e are sometimes CCA and not pure copper. CCA can easily if it is bent, though, and you can sometimes scrape the copper off the center to show a silver-colored metal in the middle.

Maximum Cable Run

The maximum distance a video signal can be sent with some video baluns is almost 1000 feet. With passive video baluns with a CAT5 cable you can transmit color video as far as 13000 feet. If you are using the cable to power cameras and also transfer video signal, then it is recommended you run a top distance of about 150 feet to avoid voltage drop. Because of the voltage drop, you should use 24V AC cameras. Also, if you use more power-hungry cameras, like infrared cameras, you need to use AC power supply at a 28V output. This is already assuming you are using three pairs of wire for a twelve volt supply and one pair for video transfer signal.

Color Convention

Make sure you check your wiring carefully. Choose a specific color convention and then stick to it. You should run one length of CAT5 cable from one DVR to all the cameras. The cable can do two jobs. Also, one pair of wires can be used for the video signals, and the other three pairs of wire can be combined to take the 12 volts of power from the transformer next to the DVR to the camera.
