Three elements for the selection of surveillance cameras for infrared cameras

Generally, when installing a monitoring project, the first three factors to consider are the clarity of the infrared camera, the monitoring distance, and the monitoring range. These are also several factors that need to be selected first when selecting an infrared camera. Especially the monitoring range is very important for the selection of infrared camera surveillance lens. The monitoring lens of the infrared camera directly determines the monitoring range, so the first consideration when selecting an infrared camera monitoring lens is how much monitoring range.

When choosing and choosing an infrared camera, you should visit the construction site to measure how far the monitoring distance is and how wide the monitoring range is. After obtaining these data, we can choose a suitable infrared camera monitoring lens. The two parameters of the infrared camera's monitoring range and monitoring distance are opposite to each other. As the so-called fish and bear's paw can't have both, the monitoring range is enlarged, the monitoring distance is getting closer; otherwise, the monitoring distance is longer, and the monitoring range is changing It's small.

When choosing an infrared camera surveillance lens, make a judgment based on the actual monitoring environment. For environments that require large-scale monitoring, it is good to choose a wide-angle lens, and for environments that require long-range monitoring, a telephoto lens is suitable. The focal length of the lens directly determines the monitoring distance and monitoring range of the infrared camera.

At present, there are various types of infrared camera surveillance lenses on the market. Some support zoom and some belong to fixed lenses. For zoom lenses, they have greater flexibility and can adapt to more surveillance environments. The fixed lens has a fixed focal length, and the monitoring distance and monitoring range are unchanged. You can only choose a lens according to the monitoring environment. When the infrared camera is monitored during the day, we can determine its monitoring distance according to the lens parameters. In addition to the focal length of the lens, the irradiation distance of the infrared light board is also an important factor affecting the monitoring distance of the infrared camera. The farther the night vision distance is.

The selection of infrared camera surveillance lenses needs to be judged according to the actual situation. Do not directly determine the type of infrared camera surveillance lenses before the surveillance environment inspection has been conducted. Buying without inspecting the surveillance environment is often worth the money.
