This is a set of three units. ■ Overview ● This unit is a network video encoder equipped with a 10BASE-T/100BASE-TX terminal (network terminal) for network use. It captures video from up to 4 analog cameras and compresses it into JPEG, MPEG-4, or H.264 images. By connecting this unit to a network such as a LAN (Local Area Network) or the internet using the network terminal, you can view the camera's images and audio on a personal computer (PC) on the network. (The audio function only supports the video input of Ch1) 【Features】 1. Motion-adaptive I-P conversion function - By detecting and processing motion areas from analog video, it generates smooth digital images even from moving video. 2. Camera coaxial communication function - Allows control of pan/tilt and lens for combination cameras (sold separately). 3. Cable compensation function - Compensates for the deterioration of analog video due to long-distance transmission, keeping the images clear. 4. No power wiring required (Power over Ethernet reception.
