MotionProtect Fibra works as part of the Ajax security system, exchanging data with the hub using the secure Fibra wired protocol. The wired connection range is up to 2,000 meters when using a U/UTP cat.5 twisted pair.
Operating principle
MotionProtect Fibra is a wired motion detector. Using an IR sensor, the detector can identify intrusions by detecting moving objects with temperatures close to that of the human body.
In the armed mode, the detector instantly transmits an alarm signal to the hub when it detects motion. The hub activates connected sirens, runs scenarios, and notifies users and the security company.
All MotionProtect Fibra alarms and events are recorded in the notification feed of the Ajax app. Users know exactly where motion is detected. The notifications contain the name of the hub (the name of the protected object), the name of the device, and the virtual room to which the detector is assigned.
The detector uses Fibra technology to transmit alarms and events. This is a wired data transfer protocol that provides fast and reliable two-way communication between the hub and the connected devices. Using the bus connection method, Fibra delivers alarms and events instantly, even if 100 devices are connected to the system.
Fibra supports block encryption with a floating key and verifies each communication session with devices to prevent sabotage and spoofing. To monitor connection with the system devices and display their statuses in Ajax apps, the protocol involves regular device polling by the hub with a specified interval.
Pet immunity
When properly installed and configured, MotionProtect Fibra does not respond to pets up to 50 centimeters tall and weighing up to 20 kilograms.
The detector is installed at a height of 2.4 meters without any obstruction to its view. For example, in a corner where the view will not be blocked by a closet or other furniture on which a pet can climb.
Temperature compensation
The detector perceives people and other objects as heat spots. The device monitors these heat spots and, if they move, detects an alarm. Under ideal conditions, the human body temperature (36.6°C on average) differs from the ambient temperature. Due to their contrast, the motion detector accurately captures the movement of a person in space.
In situations where the ambient temperature is very close to the body temperature, the detector may not operate properly; it may give false alarms or fail to respond to motion. To offset this factor, we use temperature compensation.
Temperature compensation is used in all Ajax motion detectors, so MotionProtect Fibra detects motion over the entire operating temperature range.
Sending events to the monitoring station
The Ajax security system can transmit alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) using SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other proprietary protocols.
MotionProtect Fibra can transmit the following events:
- Motion alarm.
- Tamper alarm/recovery.
- Hub connection loss/recovery.
- Temporary deactivation/activation of the detector.
- Unsuccessful attempt to arm the security system (with the system integrity check enabled).
When an alarm is received, the monitoring station operator of the security company knows what happened and where the Rapid Response Unit (RRU) has to be sent. Addressability of Ajax devices allows you to send not only events but also the type of the device, the name, group, and virtual room assigned to it to the PRO Desktop and to the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
Do not install the MotionProtect Fibra
- Outdoors. This can lead to false alarms and detector failure.
- In places where objects and structures may obstruct the detector’s view. For example, behind a flower or a column.
- In places where glass structures may obstruct the detector’s view; it doesn’t detect movement behind glass.
- Facing the window to avoid direct sun rays hitting the detector lens. This can lead to false alarms.
- Opposite any objects with rapidly changing temperature — for example, electric and gas heaters. This can lead to false alarms.
- Opposite any moving objects with a temperature close to that of the human body — for example, opposite the swinging curtains above a radiator. This can lead to false alarms.
- In places with fast air circulation — for example, near fans, open windows, or doors. This can lead to false alarms.
- In places with low or unstable Fibra signal strength. This may cause malfunctioning of the detector.
- Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.
