Remote Video Speaker Microphone (VM685)

Remote Video Speaker Microphone

Hytera’s Remote Video Speaker Microphone (RVM) is designed to capture, store and share media including audio, image and video evidence taken from the field. The body-worn camera with remote speakerphone allows users to make and receive voice communications, initiate an emergency alarm, and deliver real-time video to a control centre over the LTE network, even in low-light conditions; when paired with the Hytera Multi-mode Advanced Radio.

The Hytera RVM docks into a specifically designed Multi-Unit Charger that automatically exports audio, video, images and log files to the Digital Evidence Management (DEM) platform. This feature ensures content captured remains tamper-proof and is securely transferred to the control centre.
