view.

Precautions for Installation
•
The camera stays level with the horizon, without inclination.
•
The installation height is more than 2 m indoors and within 5-8 m outdoors. If climbing over the wall needs
to be monitored, the camera height can be 2 m higher than the wall.
•
The angle of depression is larger than 150 & Do not install the device against the light.
•
Try to install the device in a place where the light reflection from ground is weak in case of indoor
installation.
•
Try to keep the sky out of the field of view, because false alarms may be generated due to illumination
changes or cloud movement.
Other Precautions
•
Try to disable automatic white balance, the switch of which tends to cause alarm missing.
•
Set the camera to be fixed focus.
•
Do not switch from color mode to black&white mode frequently, otherwise, alarm missing occurs.
•
Try not to use the Infrared all-in-one machine outdoors, which attracts insects and causes false alarms.
•
The target cannot be oversized or undersized. The minimum target detectability is 8*8 pixels. The target
takes up 1/20-1/2 of the screen in height, excess of which leads to alarm missing.
• T
he background modeling after parameter setting needs 4-8 seconds, during which a triggered alarm is not reported.
•
A certain period of time is required from target appearance to recognition, so the duration of a target
appearing in the field of view normally needs to be more than 2 seconds.
•
Avoid too many moving targets in the field of view, which may lead to alarm missing.
•
The fill-in light at night needs to be uniform.
•
The wide-angle lens with short focal length (less than 4 mm) is recommended for small indoor space.

The software does not support pure 64-bit system. The 64-bit system mentioned above supports 32-bit
