The Hikvision 8-channel hybrid DVR with two-way audio communication is designed to support security monitoring in homes, offices, shops, and other properties. Its eight-channel capacity allows users to connect multiple compatible cameras to monitor different areas from one recording system. With compatible audio equipment, two-way audio functionality can enable communication between the monitoring location and the camera location.
