Voice Encryption to Ensure Users' Communication Security

The function provides basic voice encryption to safeguard users' communication security

More supplementary services to provide richer application experience

The hardware is newly upgraded to support a variety of services such as remote monitor, remote detection, call alert, remote kill, remote revive, etc., providing users with richer application experience.

Advantage :

AI-based Voice Recognition Technology

The built-in 36mm diameter speaker and advanced AI-based Voice Recognition technology deliver louder, clearer audio by eliminating unwanted ambient noise, reducing distortion and suppressing whistling caused by other devices in close proximity to each other. Ambient noise will no longer slow down communications and users can hear and be heard wherever they are.

Extended Communication Coverage

DR-105A utilizes a high-sensitivity receiver module and a high-efficiency monopole antenna to enhance signal penetration, providing good calls in rooms with weak signals, and maintaining stable performance and RF power output in low battery conditions.

In addition, the monopole antenna has a unique thicker thread design that is less prone to breakage and bending, which helps to increase the antenna's life, as well as increase radiation efficiency and extend radio communication coverage.

Bluetooth 5.0

DR-105A supports Bluetooth; it is fast connection, high compatibility, wide coverage, stable, no lag, and zero delay on calls.

Application

Adopting humanized appearance design, AI-based voice recognition technology, clear digital audio, with automatic roaming, GPS, Bluetooth, digital trunking and other optional features, DR-105A provides solid and reliable communication guarantee for emergency communication and management dispatching of users in business, manufacturing, railroad, airport, hotel, shopping malls, security, entertainment venues, construction sites and other industries.
