AJ-REX2 - Photo Extender

The AJ-REX2-Radio Repeater is a high-performance radio signal range extender developed by other brands to maximize the coverage of security systems in large-scale installations. This device acts as an intelligent link between the main control panel and peripheral devices (detectors, sirens, keypads), doubling the effective communication area.

The major technological innovation of this repeater is its full support for transmitting heavy data packets, enabling real-time alarm photo verification. When a camera detector is activated, the repeater instantly forwards the image sequence to the user and the alarm receiving center, without loss of quality or significant delays. The device operates with encrypted two-way radio communication protocols, ensuring all information is protected against interception and jamming attempts. It also features a high-capacity backup battery that ensures up to 38 hours of autonomous operation in the event of a power failure, as well as physical tamper mechanisms against unauthorized opening or removal. It is the definitive solution for warehouses, industrial complexes, and large estates demanding absolute communication stability.
