Hytera's VM750D is a smart body camera designed to capture, store, and upload evidence such as pictures, videos, and audios in the field, especially for those involved in public safety. Over 3G, LTE, or WLAN, the VM750D allows you to stream the real-time video in the field to the command center for better situational awareness and make a voice call simply by pressing the push-to-talk (PTT) key. With a 160° diagonal field of view (DFOV), the VM750D expands your view in a significant way, seeing almost as much as your eyes can. So you can capture more details, with this incredible camera. The built-in smart multi-functional sensor in the VM750D can detect what is happening and automatically activate an alarm in case of blocked camera, unauthorized disassembly, no movement within preset time, and a security officer who is down.
