What software can avoid the camera?

High-power laser pens with blue or green light can avoid the camera.

Just use a blue or green high-power laser pointer. COMS photosensitive element of camera is most afraid of laser, and it is easy to be damaged when it meets laser.

There is no such software, but the method of compressing magnetic flux produces high-power electromagnetic pulse, which can interfere with any electronic product.

When choosing a suitable camera, we should pay attention to the following points: pixel, viewing angle, night vision, AI humanoid detection, sound detection and storage mode.

1, pixel, resolution

The higher the pixel and resolution, the clearer the picture. Generally, 2 million pixels, with a resolution of 1080P, can well meet the monitoring requirements. If the quality requirements are very strict, you can choose a camera with 3 million pixels and 2K resolution.

2. Perspective

The horizontal viewing angle determines the visible range of the horizontal area, and the vertical viewing angle determines the visible range of the vertical area. The larger the angle of view, the more content you can see. If only one camera is installed in the same area, the larger the viewing angle, the better.

3. Night vision

Night vision distance is more important than whether the night vision picture is colored or not. There is no monitoring dead angle during the day, and there will be visual dead angle due to light at night. Try to choose a camera with long night vision distance.
