Model: Defensor-BR6
Defensor-BR6 is a tri-proof digital wireless ad hoc base station with battery built-in. It is fast deployed single box solution and provides users with reliable, fast-responsive, efficient, and secure services, like clear voice, GPS and SMS under non-line-of-sight, emergency scene and fast-moving scenarios.
Defensor-BR6 adopts anti-vibration structure for shockproof and drop resistant. Its shell is made of PC+ABS engineering plastics for waterproof and dustproof.
Product Description
Highlights
➢IP66 Protection Level
Defensor-BR6 adopts a high protection level design for a variety of harsh environments. Built-in 48Ah battery for 46hours working to gurantee the critcial communications in emergency.
➢Large Area Network Coverage
Supports 6-hopping and 10km-50km each hopping
➢Caller Location Display
Radios within each Defensor node of the ad hoc network can checkthe location of caller including distance and azimuth angle.
➢Rapid Deployment
Push-To-Start for emergency situation and tactical operation. Defensor-BR6 can complete the automatic addressing networking with other base stations within 1min after starting up.
