1.8 Built-in Sensor Issues
Problem
Cause and Remedy
The built-in sensor is not triggering the camera to buffer or transfer images.
You have not configured the camera to buffer or transfer images when the built-in sensor is triggered.
Configure a sensor trigger (see 2.2 Configuring a Sensor or Motion Detection Trigger in the Operating Instructions).
The camera is in privacy mode.
No camera images are buffered or transferred while privacy mode is activated. To turn off privacy mode, press the PRIVACY button on the front of the camera, or access the camera as the administrator and turn off privacy mode.
The built-in sensor is obstructed.
Obstacles in front of the sensor, including glass or other transparent materials, can affect the performance of the built-in sensor. Remove any obstacles.
The built-in sensor does not detect temperature difference outside of its range.
The sensor’s active detection range is about 5 m in front of the camera, about 30° horizontally, and about 85° vertically, when the camera is in a 20 °C environment.
The built-in sensor may not make detections depending on the temperature of the object or the surrounding environment.
The smaller the temperature difference is between the object and the surrounding environment, the detection range decreases and it becomes more difficult for the sensor to make detections. On the other hand, if there is a large temperature difference between the object and the surrounding environment, the detection range increases and it becomes easier for the sensor to make detections.
The built-in sensor is dirty.
Clean the built-in sensor with a soft cloth.
The built-in sensor may not perform properly in the following areas.
Where the object is exposed to direct sunlight or bright light
Where the camera is exposed to direct sunlight or bright light
Where there is an obstacle such as glass in front of the camera
In a greasy or humid place like a kitchen
Where there are sharp temperature changes like near an air conditioner
Near devices that emit radio waves, such as mobile phones
Refer to the Installation Guide and select a more appropriate location for the camera.
The lens does not turn to the sensor position after the built-in sensor makes a detection.
You have not enabled the [Lens Position When Triggered] setting.
Set the [Lens Position When Triggered] setting to [Sensor] when configuring the camera to buffer images by built-in sensor (see 2.2 Configuring a Sensor or Motion Detection Trigger in the Operating Instructions).
