Ajax vhfBridge – Reliable alarm transmission even without internet

The Ajax vhfBridge is the essential wireless module for anyone who wants to secure their Ajax alarm system even in particularly demanding or remote locations. This wireless module enables alarm transmission via vhf radio frequencies – perfect when GSM, Ethernet, or WLAN are not reliably available.

Why the Ajax "vhfBridge"?

  • Long-range transmission: Sends alarms even over long distances where other signals fail.
  • Seamless integration: Easily integrates into your existing Ajax security system.
  • Double security: Parallel operation with internet connection for maximum reliability.
  • Flexible deployment: Ideal for remote locations, mountainous regions, industrial plants or areas with poor network coverage.
  • Real-time monitoring: Fast and reliable alarm forwarding to monitoring centers or security services.

The vhfBridge converts digital events of the Ajax system (e.g., break-in, sabotage, fire) into analog signals and transmits them via VHF transmitter to a monitoring station – thus ensuring that your security solution remains functional at all times, even in the event of a total internet or mobile network failure.
