There are several situations when the camera cannot be turned on when the webcam is found: 1 Whether the connection between the camera and the host is good, and whether the network card of the host is available. 2. The camera and the host are not in the same network segment. If the camera is set to a non DHCP mode, make sure that the fixed IP address of the camera is on the same network segment as the host, such as 192.168.1. X. If the camera is set to DHCP mode, please ensure that the camera and the host are in the same LAN, and the router/switch has the DHCP sever function. 3. Whether the network permission to run the software is restricted. 4. Whether the UDP function of the network is prohibited by the LAN security policy. 5. Whether the 900790089009 port number of the LAN is prohibited. 6. Whether the power supply of the camera is sufficient. If you use a non PoE mode, make sure that the adapter is turned on and plugged in. If none of the above measures can solve the problem, please use the ipconfig command to check the network status on the PC side, and disable the network except for the same network segment with the camera to search for devices again. If the problem still can’t be solved after that, please contact our engineer for support.

There is an upgrade driver in the upgrade tool. If the driver is not installed, this problem will occur. After the driver is successfully installed, the flash back problem will be solved.

Whether for UTool used by DCAM series or NebulaGUI used by DS series, the IR and Depth images saved by both are 16bit image data, which cannot be opened by using the system's own image browser, but can be opened and viewed by using software such as ImageJ; The point cloud map saved by the GUI is in. txt format. From top to bottom, it is the coordinate point information from pixel 0 to the last pixel. The values in each row are the X, Y, Z coordinates of the pixel. The saved point cloud map can be viewed using CloudCompare software. For related instructions, please refer to the link:https://cdn.yun.sooce.cn/4/62267/pdf/16339227552770a0bd9e3dcaf8a6b.pdf

TOF camera calculates the distance from the object to the camera by calculating the time between the light from the camera and the return light from the object received by the camera. Different object surface colors and materials have different reflectivity and absorptivity to light. Therefore, if the measured object is a smooth black object, it may not be recognized. The following methods can be tried: 1. Reduce the product frame rate (for example, 5 frames) and increase the exposure time (for example, 4000); 2. Change the Confidence filter threshold to 2 or 5

DS series does not support parameter configuration such as device output mode, but only supports changing device network mode and IP. If you need to change the camera output mode, frame rate and other parameters, you can call the SDK interface. For specific methods, refer to the SDK development documentation.
