Name | 3channels+1 channel video control multiplexer |
| |||||||
Model | SD-S803VCS/R | Size | 181MM*123MM*29MM 181MM*101MM*29MM | ||||||
Introduction | Via video multiplexer method,realize 4 channels video signal transmission in one video SYV or SYWV cable,also,realize 3 channels video and 1 channel negative data transmission by change-over switch. All data is in real time transmission,HD image ,no delay Suitable for NEW project or modification works. | ||||||||
Product function and features | 1,as project demand,the device is optimized interface,and is convenient for installment with mini volume; 2,Transmit 4 channels video or 3 channels video +1channel negative RS485 control signal optionally through selector switch; 3,RS 485 control interface can be driven by special chip with 15Kv anti-static module ,which can be 64 nodes; 4, under HS frequency reuse way, signals are combined with high speed without any delay and disturbances; 5,adjustable knob is installed in receiver,which can fine adjustment transmission distance,so that get better video effect; 6, brightness degree of video signal can be adjusted at the transmitter according to different camera; 7,12V DC power supply,built-in; 8,all ports use high quality IVXBNC interfaces; 9,ocular data transmission status with RS485 signal indication; The device has high energy conservation circule | ||||||||
