AXIS Q1656-DLE Radar-Video Fusion Camera
Troubleshooting
Problems with the radar-video fusion
The bounding box is not
covering the object precisely
If there is no video analytics detection, the camera will show the projection of the radar detection
in the image, and that is not as accurate as a video analytics box. If the box is too high or low,
make sure that the installation height is set correctly. It could also be due to elevation differences
in the scene, like a sloping road, a hill, or a depression.
The bounding box shift its
position when tracking an
object
When both radar and camera analytics detect the same object, or if only the camera analytics detect
and object, the bounding box will be tightly drawn around the object using the camera information.
If the video detection is lost, the bounding box will be drawn at the position of the radar projection,
which is less accurate. Once the video detection is picked up again, the bounding box will be
drawn in the correct position again.
I don’t get the same
detection distance as the
manual says
There are several factors that affect the detection distance:
• Check that the correct height is entered in the settings.
• Depending on the approaching angle of the object towards the installation point, the
detection distance can vary. At the outer parts of the field of view, the detection
sensitivity is lower from a radar perspective. Consider aiming the Q1656-DLE towards
where the intruder is expected to get the furthest distance.
How can I minimize false
alarms?
Here are a few tips to minimize false alarms:
• Make sure that the scene is well lit to maximize detection probability of video analytics
• Set the sensitivity to
Low
in AXIS Object Analytics. This requires that video and radar
analytics agree before triggering an alarm.
• Use exclude areas in the radar to mask known sources of false detections, such as
swaying vegetation, and buildings.
• Configure the radar to use low sensitivity.
• Use exclude areas in AXIS Object Analytics
• Keep the grass short.
Radar interference
The device uses one of two radar channels. Within each channel, up to four radars can negotiate
how to best use that frequency. Sometimes you may see a warning message about interference
from the camera, despite this functionality. You can then manually select a channel for each device.
Devices that are physically close to each other should be set to the same channel. This makes it
easier for the devices to avoid interference.
Performance considerations
The following factors are the most important to consider:
•
Heavy network utilization due to poor infrastructure affects the bandwidth.
