Often asked: Cctv What Pairs To Use For Power Cat 5?


Can Cat 5 be used for CCTV?

By using a CAT5 cable you can run CCTV colour video footage over 1000 metres. This is a fantastic feature of a category 5 cable. EMI (Electromagnetic interference): As CAT 5 cables use twisted pairs, it helps to keep your signal away from EMI (Electromagnetic interference).

How do you use a CAT 5 wire for power on security cameras?

Normal security cameras use 9 to 12 volts to operate.

  1. Run CAT – 5 cable form the monitoring location to the security camera location.
  2. Strip about 1/2 inch of the sheath from the wire to locate the rip cord, then pull it back 3 to 5 inches along the cable length.
  3. Choose the wire color that will be used for the video.

What pairs does CAT5 use?

The four wire pairs in a CAT-5 cable are distinguished by the color of their insulation. The four colors are (in order) blue, orange, green and brown. Thus, when refering to the “second pair ” of wires, it is the orange pair.

How far can I run Cat 5 cable for CCTV?

Maximum Cable Run 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.

Which cable is better for CCTV?

For CCTV frequency, RG59 and RG6 coaxial cables are recommended from Finolex Wires and Cables for optimum performance, non-distorted and noise-free video transmission.

Can I use Cat6 for CCTV cameras?

* Cat 6 cables only support speeds up to 10Gbps up to around 55m (180 ft). For most CCTV setups, you’ll want to use cat5e Ethernet cable. Cat5 is slow and outdated, and rarely used anymore. Cat6, on the other hand, is a bit of an overkill for most surveillance systems.

What voltage can Cat5 handle?


Property Nominal Unit
Max tensile load, during installation 100 N
Wire diameter (24 AWG; 0.205 mm2)) 0.51 mm
Operating temperature −55 to +60 °C
Maximum DC operating voltage (PoE uses max 57 V) 125 V


Can you run PoE over Cat5?

[A] Yes. Power over Ethernet is a developing technology whereby supply voltage is provided to certain types of devices through the same cable that is providing the data signal, such as CAT 5 Cable. These type of devices are called ” PoE Compatible” (or “Active Ethernet Compatible”).

Does Ethernet use all 4 pairs?

Gigabit ethernet (or 10/100/1000 Mbps) gets all its super-charged data power from using all four pairs, or all eight wires, when transferring the full 1000 Mbps of data from one computer to another.

Why does Cat5 have 8 wires?

The 8 wires make up 4 pairs of transmit and receive. Think of them as lanes on a highway. In 10/100 Mbps speeds, 4 wires or 2 pairs are used, equating to a two lane highway in each direction. It allows decent traffic to pass but gets clogged easy if a few semis (read Ethernet streaming video) get on the highway.

Is Cat 6 better than Cat 5e?

Cat 6 is cable that’s more reliable at higher speeds than Cat 5 or Cat 5e. They look pretty much the same; in fact, Cat 6 is backward compatible with Cat 4, so you can mix and match. Cat 5e cable is enhanced to reduce interference so that it can reliably deliver gigabit speeds.

How far can you run Cat6 cable for CCTV?

Max length of Camera Cat5e/ Cat6 cable run Print Per Ethernet standards, the maximum length of a Cat5e and Cat6 cable run is 100 meters (or 328 feet).

What is the difference between cat5 and Cat6 cables?

The main difference between cat5 and cat6 cables is reduced “crosstalk” and faster speeds in the transferring of data and connection. The speed of a cat5 cable can handle up to 10/100 Mbps (megabytes per second) at 100 Mhz bandwidth, a speed that was quite efficient in earlier applications of the cat5.
