1. What is the advantage of using Passive Video Balun?
Video balun is to convert the video signal into the balanced signal applicable to betransmitted on common Cat-5 unshielded twisted pair wire.With perfect transmission effect, which can be applied in the occasions such as video monitoring and video meeting and can transmit four channels of video image simultaneously on an 8-core Cat-5 twisted pair wire. It can simplify the wiring project and save wire use quantity.
*Adopt differential signal transmission with excellent anti-jamming ability
*Save project wire expenses, each a pair of twisted pair wire transmits one channel of video signal and one common Cat-5 unshielded Twisted pair wire can simultaneously transmit four channels of video signal.
*Full-motion CCTV video at distances up to 330mwhen used with any passive UTP video transceiver
*Up to1500mwith any active UTP video receiver
*No power required
*Built-in transient Suppression protection
2.Which type of wire required for video balun?
Unshielded Cat-5 or above twisted pair wire (Please use standard Cat-5 or above twisted pair wire.
The wire quality will directly affect the transmitted image effect and transmission distance.)
Characteristic impedance: 100Ω±20Ω
DC loop resistance: 18Ω/100m
Differential capacitance: 62pf/m (Maximum)
Clamp modular plugs for a Cat-5 unshielded twisted pair wire according to the connection order of TIA/EIA-568B,connect the Clamped modular plugs to the RJ45 sockets, connect the coax to the BNC.
(Excluding 16ch baluns which only have screw terminal block)
3. Why using a CCTV Tester?
The CCTV Tester is designed for On-site installation and maintenance of video monitoring system. It can be used for displaying video, controlling PTZ, DC12V/1Apower for camera, Audio input test, generating images, capturing data of RS485 and testing LAN cable etc. With feature of easy operation and portability design, it can simplify the installation and maintainance of the video camera. Also it enhances the working efficiency with lower expenditure of the project.
