1. Support 1080P, support 165MHz/165Gbps single channel (4.95Gbps all channels) bandwidth. 2. Use Cat6 network cable (recommended), the transmission distance can reach 30 meters, and the resolution can reach 1080P. 3. Support uncompressed audio two-channel audio transmission, such as LPCM. 4. cable is connected according to the IEEE-568B standard. No external power supply required. Simple installation. Pls Note: 1. Pls use AMP for-original cat6 pure copper network cable then it can reach 30m and can transmit 1080P images, other factory network cables can only transmit up to about 24 meters. if use the cat5e network cable can only transmit 720P images. 2. cable of the finished interface, no matter if you are using super Cat6, super Cat7, or Super human beings, don' work, it cause the screen to flicker and no image. Personal summary after testing: the quality of cable determines the image effect, please do not use cable that does not meet the requirements. Connection method: 1. Connect the signal source (such as DVR, NVR hard disk recorder) to the sending end of the extender. 2. Use Cat6 network cable to connect interface of the sender and receiver. 3.
