Note: If the network card chip is Intel 219 model, it will cause frame loss, so do not choose this network port to connect the camera.

1. Click the Configure button in the image above, select the Advanced tab, select Jumbo Packet in Properties, and set the Value to the maximum available option.

Note: Not all network cards support Jumbo Packets.

1. On the Network Connections page, right-click the host network card connected to the camera, select Properties, and select Internet Protocol Version 4 (TCP/IPv4).

Note: Setting the host network card's IP address to a fixed address is to improve the reliability of the connection between the host and the camera.

1. **Check if the camera driver is the specified version**
2. Install the corresponding version of the camera driver according to the camera brand used.
3. Set the camera IP address and the host IP address to the same network segment, but not the same IP address.
4. Use the driver to acquire images and set relevant parameters.

Note: 1. You can set the host network card IP address to an address less than 128 in the same network segment, and the camera IP address to an address greater than 128 in the same network segment.

2. After setting the fixed IP address on the host network card, you can view the camera's IP address and the IP address of the host network card connecting to this camera through the network port camera IP configuration tool that comes with the camera driver.

**V. Check if the camera image acquisition module in the vision software is set to self-trigger**

1\. Open all threads in the vision software and check if the trigger mode of the camera image acquisition module is set to self-trigger.

Note: 1. If two camera image acquisition modules use the same camera, after the camera image acquisition module set to self-trigger acquires an image, the camera image acquisition module set to software trigger will fail to acquire images, and this will happen consistently, not sporadically.

**VI. Check if power options are set to High Performance**

1\. Open Control Panel / Hardware and Sound / Power Options, and set the preferred plan to High Performance mode.

Note: 1. This item will not cause the software to freeze images, but it will affect the software detection time.

2. If you don't see High Performance mode in the preferred plans, you can open "Show additional plans" to check.
