Hytera HM785 UHF DMR mobil transceiver / Bluetooth, GPS
Description
The Hytera HM785 DMR mobile radio is the next generation of professional digital mobile radio providing greater flexibility and scalability. This mobile radio with DMR technology supports a single control head as standard with options for remote control head mounting and dual control head to suit different environments (such as vehicles, motorcycles and fixed control rooms) ensuring efficient communication. The new UI interface facilitates faster operations and the AI-based noise cancellation technology guarantees clearer voice even in the noisiest environments. It is also the first ever DMR radio that can support the IP Transit Solution feature. It comes with a rich digital mobile feature set including a broad range and ability to integrate into existing services, which provides greater efficiency. Built-in Bluetooth 5.0, allows wireless accessory (such as wireless remote speaker microphone) adaptation and data transmission.
- Screen: 2.4-inch colour screen with simple UI interaction to improve operation
- IP Transit Solution: first ever Hytera DMR radio that can support the IP Transit Solution feature
- Function Button: patented button structure design provides greater feedback to the operator with 6 programmable keys for customised operation for quick access to features used on regular basis
- Faster Cooling: improved case design improves heat dissipation to improve cooling when using higher transmit power levels
- High Reliability: textured features make it easier to distinguish each functional area. The frame has a greater wear resistance and enhanced screen design provides greater reliability
- Scalable ports: accessory Port and Ethernet Port provide connectivity to external accessories and other devices
MORE FLEXIBLE
Flexible control heads and accessories allow installation according to the users requirements. The connection cable of the remote control head can be either 3m, 10m or 40m as standard. A connection cable of up to 120m is also available (Customisation required).
CLEARER AUDIO
Adopts AI noise cancellation technology to filter out background noise (such as road noise), eliminate echoes, enhance speech and reduce howling when in close proximity to the transmitting radio. With this technology, the mobile radio provides crisper and clearer audio when transmitting and receiving voice calls.
MORE RELIABLE
Improved receiver sensitivity improves audio quality in weak signal areas to provide clearer audio.
RICH SCALABLE APPLICATION
Supports multiple connections through the accessory and network (Ethernet) ports. It also supports Clarity Transmission and back to back connections which will greatly facilitate your solutions.
