How to run a CAT5 cable for CCTV cameras
Many CCTV engineers have started using CAT5 cables for CCTV application. Are you one of those who wants to know exactly how to run a CAT5 cable for CCTV application? This article explains how to use CAT5 in CCTV application.
Selecting the correct type of cable
If you are planning to run the cable outside, it is advisable that you use shielded twisted pairs. In fact, it is best to use CAT6 instead of CAT5. When the cable is screened, it gives extra protection to your cable. Any unwanted external noise will be eliminated.
CAT5 cables are mostly sold as a 300m drum.
Buying all other accessories
CAT5 or 6 cables require active or passive balun at the camera’s end for termination. If you are running more than four channels, you can use a 4-way passive at the recorder’s end. By using ferrules, CAT5 cables can be terminated.
All terminations should be protected by a junction box. It is advisable to use an IP rated junction box, for example, P55.
Don’t use IP66 to conceal connections, as using airtight boxes can lead to corrosion.
Make sure you have all the required tools. You will require side cutters, cable strippers, cable crimp, multimeter, PPE, cable testers, CCTV video tester and other extra tools and equipment you require for that specific job.
