Mechanical Dimensions
The dimensions is in millimeters：
The cameras are interfaced to an external circuity via 17-pin connectors located on the housing and contain power, I/O, Ethernet,
and serial signals. The interface is threaded. Tightening the interface during use can reduce the loosening of the interface caused by
on-site vibration. There are three indicators on the side of the device that show the device status. There are M2/M3 screw holes on
the side and bottom of the device for fixing the device.

CHAPTER 5 FAQ
Trouble Shooting
Trouble:
Possible Reason1: The device is not powered on
Solution1: Check whether the power connection of the device is normal (observe whether the top PWR light is solid
green), and ensure that the device is powered on normally.
Possible Reason2: The network connection is abnormal
Solution2: Check whether the network connection is normal (Observe whether the top LNK light is flashing green, and
the ACT light is solid yellow), make sure that the network cable of the device is connected normally, and the PC network port and
the device are in the same network segment.
No device found when running the client
Possible Reason1: The brightness of the light source is not enough
Solution1: Appropriately increase the brightness of the light source or replace it with a brighter light source.
Possible Reason2: The exposure and gain are adjusted too low
Solution2: Appropriately increase exposure and gain.
Live view is black/dark
Possible Reason: The network line speed is not 1000Mbps
Solution: Check if the network transmission speed is 1000Mbps and above.
