The image delivery time to Ajax apps depends on the resolution of the images, connection to the range extender, level of the Wings signal, and the speed of the Internet connection. The alarm messages are delivered immediately.

* The detector requires up to 3 seconds to start the Photo on Demand shooting. ** Delivery time for one image provided that the signal strength between the hub and detector is 2-3 bars, and the hub is connected to the Internet via Ethernet, Wi-Fi or 4G. *** Values were calculated with a signal strength of 3 bars between ReX 2 and the detector, and between the hub and ReX 2. The hub is connected via Ethernet, Wi-Fi or 4G. **** Values were calculated with a signal strength of 3 bars between ReX 2 and the detector. The hub is connected via Ethernet, Wi-Fi or 4G.
The Jeweller and Wings Signal Strength Tests determine the signal strength and stability at the intended location of the device.
The Detection Zone Test helps to determine at what distance the detector will detect motion. To determine the Detection Zone, monitor the LED indicator of the device: during the test, it lights constantly, and turns off when motion is detected.
The Signal Attenuation Test helps to artificially reduce or increase the power of the radio transmitter. The test simulates a change in the room environment to check the connection stability between the device and the hub.

Photo resolution is set in the detector settings (Ajax app → Devices → MotionCam Outdoor → Settings ).
The MotionCam Outdoor detector can operate in temperatures from -25°C to +60°C with up to 95% humidity. Protection class IP55.
MotionCam Outdoor detector can ignore pets up to 80 centimeters tall when installed and set up correctly.
Detectors with photo verification have two radio modules and operate via two protocols: Jeweller and Wings. Jeweller is used for transmitting alarms and events, while Wings is used for transmitting photos.
ReX has only one radio module and supports only the Jeweller protocol.
To configure photo transmission, please use Ajax Translator version 1.10 or later.
At the same time, photo verifications are accepted by all CMSs that support SIA, ADEMCO 685 and Contact ID protocols.
Tamper is a miniature button on the device board. It reports an alarm in case of opening the device enclosure, removing the device from the mounting panel, or detaching it from the surface.
The tamper status is displayed in Ajax apps, in the Enclosure section in the states of each device. When the body status is Open, a fault symbol appears on the device icon.
The temperature is measured by sensors inside each detector, which can heat up differently due to the circulation of air currents in the room. The value may differ from the ambient temperature by 2°C.
The temperature displayed in the Rooms tab is the average of these temperatures for each detector assigned to the room. The temperature data of the street detectors is not taken into account.
To check that the device is operating correctly, carry out the detection area and signal strength tests.
The detection area tests allow you to determine the distance at which the detector will detect alarms and protect it from false triggering. In test mode, the LED indicator lights up continuously, switching off during the alarm. In order to determine the detection area, use the device’s LED indicator as a guide.
By default, the hub is set to a hub–detector ping interval of 36 seconds and 30 undeliverable data packets to consider the device lost. With these settings, the hub will detect the loss of the detector in 18 minutes.
To reduce this time, go to the hub settings in the Jeweller section and change the settings. The minimum time for detecting loss of connection with the device is 36 seconds (3 polls of 12 seconds each).
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Detector Ping Interval × Number of missed pings to determine connection failure
Note that with the minimum ping interval, short-term interference can lead to loss of connection with the device. Therefore, set the minimum values only if it is critically important to promptly inform about events in the system.
