Dear user. The length of time that the "device record" in the device control panel can be saved and the maximum record limit that can be saved per unit are set by the product manufacturer . If you think the "device record" function does not meet your needs, you can report this problem to the product after-sales party so that they can make improvements later. Thank you for your support and understanding.
Note: If your device cannot update the device record for a long time, it may be that your device is offline. Please reconnect to the network.
