Will the camera work if the hotel key card is unplugged?

The camera will not work if the store card is unplugged. After we enter the room, we can unplug the TV's power plug, which will cut off the power and the camera will not work properly.

1. Regular large-scale monitoring equipment requires ups power supply. After the external power supply is cut off, the backup power supply starts and the monitoring works as usual. The road surveillance video and bayonet video used by the public security, large enterprises Surveillance videos all fall into this category;

2. For small surveillance videos such as the cashier counter and store entrance of small stores, in order to save money, most owners do not have backup UPS power supply. Once the power goes out, the surveillance will not work. .

1. In the infrared hemisphere series machines, the image illumination is poor, white, or has a bright white aperture at night.

This phenomenon is caused by improper assembly of the machine. During assembly, the photosensitive device (photoresistor) is too far away from the hemisphere, which will cause the infrared light to be incompletely started and cause poor illumination of the machine at night.

The phenomenon of whitish images or bright white apertures is mainly caused by the infrared light emitted by the infrared light-emitting tube being refracted to the lens through the ball cover. The solution to this phenomenon is to prevent the infrared light from refracting to the lens surface, usually using a sponge. The ring is used to isolate the lens from infrared light. During assembly, the ball cover must be tightly attached to the sponge ring.

2. The image of the night vision infrared waterproof machine is normal during the day and turns white at night.

This phenomenon is generally caused by the reflection of infrared light when the machine is used in an environment with reflective objects or it is used in a small space. To solve this phenomenon, you should first determine whether there are reflective objects in the use environment and try to improve the use environment as much as possible. , secondly check whether the effective infrared distance of the machine corresponds to the actual use distance; if a long-distance infrared machine is used in a small space, the machine image will appear white due to excessive infrared light.

3. No image

First check whether the polarity of the external power supply is correct and whether the output voltage meets the requirements (power supply error: DC12V±10, AC24V±5

), secondly check whether the video connection is in good contact; if you are using a manual aperture lens, you need to check whether the aperture is open, and for an automatic aperture lens, you need to adjust the LEVEL potentiometer to make the aperture at the appropriate position.
