Features: HD video balun converts video signals into balanced signals for normal Cat-5 unshielded twisted pair transmission. With perfect transmission effect, it can be applied to video surveillance, video conferencing, etc. Can transmit four channels of video image simultaneous on an 8-core Cat-5 twisted pair wire. It can simplify the wiring project and save wire use quantity. Compatible with all HD-CVI,HD-TVI,HD-AHD. Up to 250m for 1080P AHD Cameras. Up to 450m for 720P CVI Cameras. Up to 250m for 1080P CVI Cameras Up to 250m for 720P/1080P TVI Cameras. Up to 320m for 720P AHD Cameras. NTSC,PAL,and SECAM video formats. No power required. 60dB crosstalk and noise immunity. Built-in transient suppression protection Specification: Condition: Brand New Item Type: Video Balun Color: Shown as Picture Material: Metal Compatible: HD-CVI,HD-TVI,HD-AHD Video Formats: NTSC,PAL, SECAM Frequency Response: DC to 60Mhz Attenuation: 0.5dB Type CMRR: 60dB Surge Protection: 4KV ESD: 8KV Impedance: BNC: 75ohms, RJ45: 100ohms Working Temperature: -10 -70 Storage Temperature: -30 -70 Humidity: 0-95% Type of wire required: Unshielded Cat-5 or above twisted pair cable (Please use standard Cat-5 or above twisted pair cable. The quality of the wire will directly affect the transmission image effect and transmission distance.)
