Cameras
and recorders aren’t the only things that are essential to your video
surveillance system. For your setup to work, you also need secure connections.
When you’ve decided to stick with the fool-proof stability of a wired system,
finding the most appropriate accessories for your wiring system is critical, so
you can make sure that there will be no unwanted disconnection once your system
is up and running. There are three common types of camera cables and connectors
that used in CCTV systems. These are BNC, RCA, and DIN.
The
BNC or Bayonet-Neil-Concelman connector is the industry standard when it comes
to transmitting video signal over coaxial connections. BNC connectors feature a
special locking mechanism, which ensures firm attachment to the monitor or DVR.
This unique mechanism secures the cable so that it will not come loose even
when the line gets pulled and tugged by accident. Apart from being the industry
standard for surveillance systems and CCTV cameras, BNC connectors and cables are also ideal
because they offer consistent efficiency even over long distances of up to 300
feet. Cable quality affects this efficiency, so make sure that you invest in
high-quality cables. Unwanted disconnections are prevented as BNC cables lock
in place, which also contributes to consistent image transmission.
Using
BNC cables and connectors, however, is not without its downsides, among which
is requiring a separate power source and its inability to support audio. Unlike
DIN and RCA connectors and cables, BNC can only transmit video, which can be a
major limitation for those who also want to record sound in their surveillance.
There
are various types of BNC connectors designed for specific uses, ranging from
crimp-on connectors to twist-ons, F compression connectors, and F-crimp
connectors. Your choice of BNC connector type to use should depend on the kind
of connection your system requires.
