Infrared Light Angle and Lens Focal Length Match

The infrared lamp angle has a unique connection with the lens. If it is not coordinated, the performance of the monitoring camera cannot be well reflected. Generally speaking, the angle of infrared lamps determines the infrared distance to a certain extent. The large angle of infrared lamps is suitable for a large -range large -scale monitoring camera. The light is evenly distributed, and the quality of the screen is clear. The small -angle infrared lamp board is suitable for long -distance small -range monitoring cameras, but it is usually not available to the nearby environment, which can easily cause monitoring blind spots. Only in different positions with different angles of infrared lamp monitoring cameras can meet the requirements of usual monitoring requirements. In addition, in addition to the infrared light angle affects the distance, there is also the transmitting power of infrared lights. The larger the output power, the farther and farther in the irradiation distance. The factors that affect infrared light output power are mainly the size of the light -emitting chip. At this stage, mainstream chip products include 12mil?, 14mil, 16mil, 20mil, 24mil, 40mil and other levels. The number of lens millimeters also affects the monitoring distance of the surveillance camera to a certain extent. It can be said that the distance between the infrared lamp and the focal length of the lens to monitor the distance of the camera. The longer the focal length of the lens, the farther the irradiation distance. The telephoto is mainly concerned about the irradiation distance. The longer the focal length of the lens, the farther the irradiation distance, such as 3 times optical zoom, 30x optical zoom, etc. The wide -angle lens focuses on the width of the shooting screen, the close distance, and the large -scale monitoring the camera of the camera. The focal length of the lens can calculate the angle and distance according to certain standards. To understand this main parameter, it is very easy to choose the suitable infrared light. Infrared light angle and lens focal length pairing attention to consistency. Only with an infrared lamp with an angle with a suitable angle lens can the monitoring camera fully play its good performance.
