The FAQ For CCTV Cable

Q1: How to connect BNC Crimp-ON to Coaxial Cable?
 A : Installation of the 2 Piece BNC Crimp type connector
 A crimp type connection allows for quick and simple installation while still maintaining a mechanical and electrical connection fairly close to a solder type termination. Some of the key points to remember are as follows: Make sure to use the proper size connector for the type of cable you are using. Make sure all cuts and stripping is clean. Avoid nicks as much as possible. Use the proper crimp tool, don't try to improvise with pliers, etc.
 
Follow these steps below:


Q2:How to connect BNC Twist-ON to coaxial cable?
 A : Each end of your cabling must be stripped back. Measurements of the stripped coax wire (above) can vary without any problems. However, do not allow the ?outer stranded wire? to touch (contact) the center copper wire. Inserting your stripped coax cabling into your BNC connector: If you look inside of the BNC connector, you?ll see an inner sleeve (small hole) at the end of it. When inserting your coax cable into your BNC connector, make sure that the center copper wire slips into the end of this inner sleeve in the BNC.

Q5: Why use baluns with twisted pair rather than coaxial cable?
A :Twisted pair cable is one method for video transmission. It is common used in computer network. This type of cable provides balanced signal transmission (co-axial cable is unbalanced). As two wires inside the cable twisted together, they are even exposed to any sources of electrical or magnetic interference present. In theory, a twisted pair cable need not be screened. That is why they're called unshielded twisted pair (UTP). Therefore, it can run a longer distance.
