Use a mobile thermal imaging camera that can detect heat sources, such as the Mobir air mobile thermal imaging camera, which can detect the pinhole camera. You can also lower the brightness and increase the contrast to make it easier to find small heat sources that do not generate much heat. - ** Using network detection **: connect to the hotel's Wi-Fi, turn on King, without entering the game, select network diagnosis, click to start detection. If there is more than one shared Wi-Fi, turn on the mobile game accelerator, find the hotel to prevent hidden cameras, then the hidden camera will be detected.

Nikon camera battery charging
The charging method of Nikon cameras was different between old models and new models. The old model was to put the battery into the charger. The red light flashed to indicate that it was charging. After it was fully charged, the light would stop and continue to light up. At this time, the battery could be removed. The new card machine was directly charged. It could be connected to the computer through the USB port to charge. It could also be plugged into the USB plug to charge with alternating current. For example, the Nikon 810 camera could be charged by inserting the lithium battery into the charger according to the triangle direction. The Nikon D7500 camera used the lithium battery, so it needed to be charged by the official Nikon charger. Some Nikon cameras, such as the Nikon Z9, had a special charger that could be charged by connecting the charger to the Nikon Z9 and the power supply. The Nikon Z9's USB-C port could be charged while shooting. The MCB-N14 supported hot swapping. As long as there was still power left in a battery, it would continue to supply power. The battery pack also supported USB charging and data transmission through the Eh -7P/8P.
