choosing the correct coaxial cable for CCTV applications? ____________________________
SECURITY CAMERA CABLE Closed Circuit / CCTV
PAIGE SECURITY CAMERA CABLES are designed for sophisticated security surveillance and today’s high tech multi-media distribution systems that require wide bandwidth transmissions for low loss signals. Coaxial solutions include options for varying distances as well as Siamese cables for pan/tilt/zoom or remote power applications.
Network based CLOSED CIRCUIT Camera systems make use of unshielded twisted pair (UTP) cable constructions. UTP solutions include standard as well as SIAMESE CONSTRUCTIONS FOR REMOTE POWER USE.
Most camera equipment which makes use of COAXIAL CAMERA CABLES has a characteristic impedance of 75 Ohms. In order to have minimum losses, it is important to choose a cable for security cameras with a matching impedance of 75 Ohms. Paige Coaxial Camera Cables are all made with the appropriate impedance.
RG (an acronym for Radio Guide) is the prefix for most Coaxial Camera Cables. Most common constructions are RG59, RG6 and RG11. The primary difference in these cables is the size of the center conductor with RG59 being the smallest and RG11 being the largest. Which CCTV cable to use is primarily a function of distance. The larger the center conductor, the further the distance a video signal can travel without significant signal loss.
The chart below illustrates conventional wisdom on the distances for which each cable can/should be used for CCTV monitoring. These distances are guidelines and the camera manufacturer should be consulted for their recommendation.
Distances up to:
COAXIAL CCTV SURVEILLANCE CAMERA CABLES should also have a braided shield of not less than 95%. Typically this shield is bare copper. PAIGE COAXIAL CAMERA CABLES meet this requirement. Use the links to the left to view the various Coaxial configurations available. Siamese constructions with security camera power cables attached are a popular solution.
PAIGE UTP CAMERA CABLES make use of unshielded twisted pairs, generally 24 gauge. UTP solutions are becoming more common as network based CCTV systems replace traditional ones. Paige has a comprehensive selection of UTP camera cables to match your installation needs. See the UTP Camera Cable section to the left to view available constructions.
