AJAX MOTIONPROTECT FIBRA BLACK 2YR 44404.09.BL1
MotionProtect Fibra is a wired IR motion detector. It is a vital security system component, so we have engineered this device to deliver unparalleled reliability and user convenience. Its cutting-edge hardware and software algorithms minimize false alarms to nearly zero. With a modern design, MotionProtect Fibra is seamlessly integrated into any environment. The SmartBracket mounting panel simplifies installation, while configuration in the app eliminates the need for engineers to make on-site visits to resolve minor requests.
The Ajax system uses secure two-way communication based on the Fibra proprietary protocol. It features block encryption and device authentication to prevent sabotage, spoofing, or data theft. Fibra lines are multifunctional and support connecting different types of devices to one line: sirens, keypads, and detectors with photo verification.
The Fibra communication requires minimum power consumption, with the detector consuming only up to 0.045 W at its peak. This low power consumption allows installers to connect multiple devices to a single Fibra line, extending wired connectivity.
Fibra operates on the TDMA principle. Each device has a short time frame for exchanging data with a hub, and its communication module remains inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.
