How Far Can You Run Security Camera Video On Cat 5 Cable

In recent years the invention of the video balun has meant CAT5e cablevision can be used to connect CCTV cameras to CCTV DVR recorders. All the connections can exist made using just a screwdriver, with no need for special tools or fiddly components. Before y'all commencement there are a couple of important things to know.

What components do I need?

Video is transmitted along the CAT5e cable using a pair of video baluns, 1 at the DVR terminate, and i at the camera end. We sell two types of video baluns, Standard definition and High definition designed to be used with our HD 1080P cameras and DVR recorders. Power is transmitted using screw-in DC plugs and sockets. The plug goes at the camera cease and the socket at the DVR end. Locate the camera ability supply close to the DVR.

Use the correct blazon of CAT5e cable

You lot must use pure copper CAT5 cable. Some CAT5 cable is not pure copper but CCA or copper-coated aluminium. Don't rely on the label or what the retailer says, actually check the cable yourself. CAT5, CAT5e, CAT6 and CAT6e can all exist CCA rather than pure copper. CCA tends to intermission easily when aptitude and yous tin scrape the copper off to reveal silver coloured metal in the center. All the cablevision nosotros sell is pure copper external grade.

Don't exceed the maximum cablevision run

The maximum altitude video betoken can be transferred with our video baluns is approximately 300 metres. If you are using the cable to power a camera as well as transfer video signal so we would advise a maximum distance of about 50 metres to avert voltage drop. This assumes you are using iii pairs of wire for 12 volt supply and 1 pair for video signal transfer equally per our images below.

Utilise a colour convention, stick to it and cheque carefully

It is of import to check your wiring carefully. Cull a colour convention and stick to information technology. In the examples below nosotros have used blueish for the video betoken and solid colour for +ve, white plus coloured stripe for -ve.

You demand to run 1 length of CAT5e cable from the DVR recorder to each camera. The cablevision is going to exercise 2 jobs. One pair of wires will handle the video signal, and the other 3 pairs of wires will be combined to accept 12-volt power from the transformer located side by side to the DVR to the photographic camera.

Firstly identify the polarity for all your connectors

Separate the 4 pairs of wires in the Cat5e cable. In this case nosotros are going to utilise the blue pair for transferring the video signal from the camera to the DVR. Keep this pair twisted, to reduce the chance of interference.

The green, brown and orange pairs are going to be used to accept 12-volt power from the transformer to the camera. We utilise 3 pairs of wires combined to reduce the hazard of voltage drop at the camera. Having unwound the wire use the solid colour for 12-volt +ve and the white with coloured trace for 12-volt -ve.

Hither we tin run into the cables inserted into a video balun and a power plug.

Remember to strip back the outer plastic sheath to reveal the copper conductor earlier pushing into the fittings and tightening the connector with a pocket-size screwdriver.

Note how nosotros accept combined the 3 pairs of wires for the 12 volt DC fitting.

Be aware the DC power fittings are different for the DVR end of the cable and the camera end of the cablevision. The DVR cease requires a female socket to take the 12-volt power from power supply.

The camera end requires a male person DC plug To take 12-volt power to the camera

It is important to protect the fittings from water so we recommend using weather proof junction boxes by each camera. All the components you need are available in the CCTV accessories section of our online shop.
