Highlights
➢Rugged & Reliable
Defensor-T4 water and dust proof rating is IP67, which ensures outstanding performance even under harsh environments.
➢Secure Communication
IFLY military tactical communications system owns the independent intellectual property rights of the single frequency relay technology, which makes it difficult for hackers to monitor the voice communication. Defensor-T4 also supports customized voice encryption to meet users needs of multiple levels security.
➢Supports Wireless Ad Hoc Networking
Wirelessly connect with Defensor base station. If one base station moves away from the network or malfunctions, it will automatically route to another Defensor base station to guarantee link continuity.
➢Smaller, Lighter
The Defensor-T4 is 5*2.2*1.2inches, Weighing 10.6oz
➢Long Battery Life
In digital mode, the Defensor-T4 can operate for approximately 16 hours under a duty cycle of 5-5-90.
➢GPS Positioning
Built-in GPS/Beidou satellite module. The positioning information is initiated when a call is taken, and software in command center will display these each handset's GPS information.
