CCTV Accessories/Video Balun-CJ-1800R/T Active Video Balun
Specification of Video Balun
- Frequency response: DC-8MHZ
- CMRR (Common Mode Rejection Ratio): 60DB
- Impedance: BNC terminal: 75Ω, Connection terminal: 100Ω
- Working temperature: -10DC-70DC
- Storage temperature: -30DC-70DC
- Applicable to NTSC, PAL, SECAM and CCIR systems
- External dimension: 105mm*58mm*29mm (excluding BNC)
- Power supply: DC12V
Characteristic
- 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
- The farthest transmission distance will be 1500m if it is used with passive transceiver (CJ-UTP600P, CJ-201E, CJ-202E, CJ-201C) and the farthest transmission distance can reach 2400m if it is used with active transmitter (CJ-1800T)
- Built-in transient suppression protection
Use
CJ-1800R receives balanced signal to converts it into unbalanced signal and raises the received signal with perfect receiving 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 a 8-core Cat-5 twisted pair wire. It can simplify the wiring project and save wire use quantity.
Other
- Type of the required wire:
- 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)
