uxcell 2pcs Split Joint Mini CCTV Camera BNC Passive Video Balun Transceiver

the super anti-interference video transceiver is a passive (non-amplified) device that allows the transmission of real-time monochrome or color video over unshielded twisted-pair (utp) telephone wire. Baseband (composite) signals of any type are supported Features: 1. Transmission distances of color signal up to 1,000ft(300m) 2. Exceptional interference rejection, built-in unique lrc passive anti-interference filter circuit, effectivelymon-mode noise 3. Male BNC allows connection directly to the camera or DVR. 4. Reliable screwless utp terminal connection 5. No power required 6. Built-in transient protection 7. Iimited lifetime Technical specifications: 1. video: frequency response: dc to 5mhz attenuation: 0.5db typ common-mode/differential-mode rejection 15khz to 5mhz 60db typ 2. impedance: coax, male bnc: 75 ohms utp, screwless terminal blocks: 100 ohms 3. power: no external power required 4. environmental: temperature -20 to +75 degrees humidity(non-condensing) 0 to 95 percent transient immunity: per ansi/ieee 587 c62.41 5. wire type: network wiring: one unshielded twisted-pair 24-16 awg (0,5-1.31 mm) category type: 5 or better impedance: 100+-20 ohms cc loop resistance (24 awg) 52 ohms per 1,000ft, (18 ohms per 100m) differential capacitance: 19 pf / ft max (62pf/m max) 6. mechanical: size: 18 x 2.2 x 1.5cm / 7.1 x 0.9 x 0.6 inch (L*W*H)
