MotionProtect Outdoor User Manual


MotionProtect Outdoor is a wireless outdoor motion detector for the Ajax security system. The detector communicates with the hub via protected Jeweller radio protocol at a distance up to 1,700 meters in the line of sight. MotionProtect Outdoor features protection against blocking the detector view (anti-masking system) and triggering by pets (pet immunity). The motion detection distance is adjustable: from 3 up to 15 meters.

MotionProtect Outdoor can operate both on pre-installed batteries or use an external power supply. Depending on the detector settings, the batteries’ life is up to 5 years.

MotionProtect Outdoor does not support connection via the ocBridge Plus and uartBridge integration modules.

The user can configure the detector via the Ajax app for iOS, Android, macOS, and Windows. The security system notifies users of all events through push notifications, SMS, and calls (if activated).

The Ajax security system can be connected to a central monitoring station of a security company.

Operating Principle

When the system is armed, the detector continuously receives signals from two PIR sensors. If both sensors detect identical motion, MotionProtect Outdoor instantly transmits an alarm signal to the hub and blinks with a green LED. MotionProtect Outdoor ignores animals, birds, insects, as well as swaying plants and trees.

By a motion alarm, the security system also can activate sirens and notify a security company if connected.

The detector recognizes motion and sends the first alarm immediately, but next alarms until disarming are transmitted no more than once in 5 seconds.

If a motion is detected before the system is armed, the detector will be armed not immediately, but during the next polling by the hub.

Anti-masking system

Masking is an attempt to block in any way the view of the detector’s lens.

MotionProtect Outdoor detects the following types of masking:

  • An obstacle in front of both lenses (an object on the height of the detector and at a distance of up to 20 cm in front of it)
  • An obstacle in front of any of the lenses (an object at a distance of up to 10 cm in front of one of the lenses)
  • Painting or pasting any of the lenses with an opaque substance
  • Pasting the detector front side with an opaque substance
  • Applying an aerosol or painting the detector front side with paint

If one or more types of masking are detected, the detector generates a masking alarm and lights up a green LED for 1 second.

MotionProtect Outdoor detects masking regardless of the security state: armed or disarmed.

    ajax motionprotect outdoor

For the detection and interfacing to occur, the detector should be located within the coverage area of the wireless network of the hub (at a single protected object). Request for connection to the hub is transmitted for a short time at the time of switching on the device.

MotionProtect Outdoor turns off automatically after 6 seconds, if it failed to connect to the hub. To retry the connection, you do not need to switch off the device. If the detector has already been assigned to another hub, turn off MotionProtect Outdoor, and then follow the standard addition procedure.

If the connection to the hub failed, repeat the connection attempt after 30 seconds.

The device connected to the hub will appear in the list of devices of the hub in the app. The update of the detector statuses in the list depends on the device ping interval set in the hub settings (the default value is 36 seconds).

To avoid masking alarms, switch off anti-masking in the device settings before the installation!

How to find the firmware version or the ID of the detector or device?


Sensitivity level of the motion detector.

The choice depends on the type of object, the presence of potential sources of false alarms, and the protected area:

  • Low — there are likely sources of false alarms in the protected area. For example, tall bushes.
  • Medium (default value) — recommended value, suitable for most objects. Do not change it if the detector is working correctly.
  • High — there is no interference in the protected area, the maximum detection range and speed of alarm detection are important. For example, if the detector is installed in a narrow passage.

Functionality Testing

The Ajax security system allows conducting tests for checking the functionality of connected devices.

The tests do not start immediately but within a period of 36 seconds when using default settings. The test time start depends on the settings of the detector ping interval (the “Jeweller” menu in the hub settings).

Jeweller Signal Strength Test

Detection Zone Test

Attenuation test

According to the requirements of EN50131, the level of the radio signal sent by wireless devices is reduced during the test mode.

Choosing an installation place

Before installing the detector, conduct the Jeweller signal strength test.

Install MotionProtect Outdoor at the height of 0.8 – 1.3 m, ensuring the upper lens axis to be parallel to the ground, and the supposed intrusion path is perpendicular to the lens axis.

When choosing the installation place, consider the maximum device detection range. It depends on the sensitivity level and the position of the regulator for adjusting the motion detection range.

Regulator position Sensitivity level Motion detection range
(minimum range)
Low / Middle / High up to 3 meters
(middle range)
Low up to 7 meters
Middle / High up to 8 meters
(maximum range)
Low / Middle / High up to 15 meters

The detection range was tested at an ambient temperature of +23°C and clear weather. In other conditions, the detection range may vary. When choosing an installation place, use the Detection Zone Test to determine the sector in which the device detects movement as accurately as possible.

To avoid false alarms due to rain or snow falling on the masking sensors, install MotionProtect Outdoor under a covering. To protect masking sensors in the open area, use Hood for MotionProtect Outdoor cover.

MotionProtect Outdoor sends an alarm to the hub only if both PIR sensors detect identical motion. The difference in time of motion detection should not exceed 1.5 seconds.

Check the detector functioning at the alleged installation place. When choosing the location of MotionProtect Outdoor, take into account the radio signal communication range.

If the signal level is low (one bar), we cannot guarantee the stable operation of the detector. Take all possible measures to improve the quality of the signal. At least, move the detector: even a 20 cm shift can significantly improve the quality of signal reception.

If after moving the device still has a low or unstable signal strength, use a radio signal range extender.

Be careful when mounting the attachment panel. Excessive force during its mounting can lead to deformation of the panel and, consequently, to the inability to install the detector or to its unreliable fixation. Attach SmartBracket with the bundled fixing tools. Using any other tools, e.g., large diameter screws may damage the attachment panel. We do not recommend using double-sided adhesive tape for permanent mounting. The tape runs dry with time, which can cause falling, false triggering, and detector malfunction.

Do not install the detector:

  • Without Hood for MotionProtect Outdoor in a place without a covering.
  • Opposite the trees whose leaves can be in the detection zone of the upper and lower PIR sensors of the detector.
  • Opposite the bushes higher than 80 cm.
  • Near metal objects and mirrors (they can shield the radio signal and lead to its attenuation).
  • Closer than 1 meter from the hub.

Note that MotionProtect Outdoor does not detect movement behind the glass. Therefore, do not install the detector in locations where glass objects can obstruct the detector’s view. For example, in places where a glass door can obstruct the view of the device.

Install detector at a height 0.8 to 1.3 meters so that its upper lens looks parallel to the ground. If the site is uneven, the installation height is considered from the highest point of the territory controlled by the detector.

Detector installation procedure

  1. Fix the SmartBracket attachment panel on the surface temporarily using bundled screws or double-sided adhesive tape. Consider the installation height: 0.8 – 1.3 meters.
    ajax motionprotect outdoor
  2. Select the motion detection distance (3 to 15 m) using the adjustment scroll bar.

  3. Put MotionProtect Outdoor on the SmartBracket attachment panel. Leave the detection area (horizontal detection angle — 90°) and make sure that there are no moving objects within the detection area to calibrate anti-masking sensors properly.
    ajax motionprotect outdoor

    Attention! The anti-masking sensors will begin to calibrate automatically when the detector has been put on the SmartBracket attachment panel. Calibration lasts up to 30 seconds and is followed by the flashing upper and lower LED indicators.

  4. Conduct the Detection Zone Test for upper and lower sensors separately, both sensors simultaneously, and anti-masking test in the Ajax app. If the detector does not react to motion, select the appropriate sensitivity level, detection range, and check the detector slope angle.
  5. If all tests have been appropriately passed, fix the SmartBracket to the surface with screws permanently, put MotionProtect Outdoor on the attachment panel, and wait until the end of calibration. Fix the detector on the attachment panel with the bundled screw.

Connecting External Power Supply

MotionProtect Outdoor can use external power supply 5-28 V DC, 200 mA. If the external power supply is connected, there is no need to remove the pre-installed batteries. Batteries provide the detector with the backup power source.

To connect the external power supply:

  1. Disassemble the detector body: remove the screws and open the lid.
  2. Break off special caps on the SmartBracket attachment panel:
    ajax motionprotect outdoor

    1. A cap for putting out the power supply wire behind the SmartBracket attachment panel
    2. A cap for putting out the power supply wire below the SmartBracket attachment panel

  3. Run the external power supply dead wire through the attachment panel and cap.
  4. Connect the cable to the terminal strips observing polarity. Fix the wire with the clamp.
    ajax motionprotect outdoor

    3. Terminal strips on the detector board
    4. The clamp on the back of the detector body

  5. Switch on the power supply. The value of the External Power Supply field in the detector settings will change to Connected.

    Use grounded power supply source only!

  6. Fix the rear of the body with screws, install the detector and wait until the end of calibration.


Check the operational capability of the detector regularly. Clean the detector body from dust, spider web, and other contaminants as they appear. Use soft dry napkin suitable for tech equipment.

Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the detector.

The pre-installed battery ensures up to 5 years of autonomous operation (with the 3 minutes ping interval by the hub). If the detector battery is low, the system notifies the user, and the LED indicator smoothly lights up and goes off if motion is detected or the tamper is triggered.
