16-CH-Passive Video Balun

16 CH Passive UTP Video balun Video balun is to convert thr video signal into the balance signal applicable to be transmitted on conmmon Cat-5 enshield 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 quality Features: Adopt differential signal transmission with excellent anti-jamming ability Save project wire expenses,each a pair of twisted pait wire teansmits one channel of video signal abd one common Cat-5 unshielded twisted pair wire can simultaneously transmit four channels of video signal Full-motion CCTV video at distances up to 330m when usde with any passive UTP video transceiver Up to 1500m with any active UTP video receiver No power required \ Built-in transient suppression protection Technical specifications: Frequency response :DC-8MHZ CMRR(Common Mode Rejection Ratio):60DB Impedance:BNC:75Ohm,RJ45:100Ohm Working temperature:-10°C-70°C Storage temperature:-30°C-70°C Applicable to NTSC,PAL,SECAM and CCIR systems External dimension:430mm*169mm*44mm(excluding BNC) Type of the requied wire: Unshielded Cat-5 or above twisted pair wire(Please use standard Cat-5 or above twisted pair wire quanlity will directly affect the transmitted image effect and transmission distance) Characteristic impedance:100Ohm +20Ohm DC loop resistance:18Ohm/100m Differential capacitance: 62pf/m(Maximun)
