Surveillance camera have become an important part of our safety, affecting everything from personal safety to property security. With current technological advancements, safety products are also evolving. Therefore, determining the appropriate installation height for video surveillance has become a concern.

1. camera monitoring height: Indoors, the height from the ground should not be less than 2.5m; outdoors, it should not be less than 3.5m.

2. camera monitoring and their accessories, such as lenses, protective covers, brackets, and wipers, should be securely installed, operate smoothly, and protected from damage, ensuring harmony with the surrounding environment.

3. In environments with strong electromagnetic interference, the camera monitoring installation should be insulated from the ground.

4. Separate signal and power cables should be introduced, with exposed portions protected by flexible conduits to avoid affecting the pan-tilt unit's rotation.

5. Surveillance camera installed in elevator cars should be positioned on the left and right sides above the car door, effectively monitoring the facial features of passengers inside the elevator.

Furthermore, for home use, the following data can be used as a reference for camera monitoring height: Built-in lenses in cameras typically come in the following specifications: 3.6mm, 4mm, 6mm, 8mm, and 12mm. The smaller the focal length, the larger the aperture. Therefore, the installation height and distance depend on the specific site and camera parameters. Generally, if the site allows, the height should be no less than 3 meters and no more than 8 meters. Lower installations are more susceptible to damage, while higher installations make future maintenance inconvenient.
