How to choose thermal vision camera?

With the development of autonomous driving, people’s time in the car space is increasingly released. So let me tell you a few big points.

1.Thermal imaging camera detector resolution.

2.Lens focal length of infrared camera.

The lens of a general thermal imaging camera can be replaced. But the manufacturer’s standard is usually a lens. Basically, all manufacturers come standard with a lens of about 20mm. This kind of focal length lens basically takes into account the two aspects of the field of view size and magnification. The average customer can use a standard lens.

Optional is a 115mm telephoto lens or a 10-15mm wide-angle lens. A telephoto lens will increase the recognition rate at a long distance, but will greatly reduce the field of view. On the contrary, the short-focus lens greatly increases the field of view, but it reduces the recognition rate.

3.Image spacing.

spatial resolution, field of view, and recognition distance are determined by detector resolution and lens focal length. These four indicators, many brands are promoting. In fact, the resolution of the detector of the infrared camera and the focal length of the lens are fixed. These four indicators are fixed. These four indicators are calculated. So don’t pay too much attention when shopping.

4.Frame rate

The frame rate is the second most important indicator in the purchase of infrared cameras.

The frame rate refers to the number of images that can be captured, processed, and represented by the camera within 1 second. The general TV frame rate is 25 Hz. In general, the frame rate of the infrared camera should reach 30HZ, preferably 50HZ, otherwise the infrared camera will not be able to work in many workplaces. The frame frequency directly indicates the performance and response speed of the thermal imaging camera.

Temperature range

This is the most important indicator for the third thermal imaging camera. Each model has its own specific temperature range. Therefore, the user’s measured temperature range must be considered accurate and comprehensive, neither too narrow nor too wide. Therefore, the user only needs to purchase an infrared camera within his own measured temperature.

Automatically search for the highest, lowest, average temperature.

and high and low temperature sound and color alarms. This part will be very useful in practical use. Many mid-to-high end models have this function.

Is it possible to move the temperature measurement point and the temperature measurement area?

This is the fourth most important indicator of thermal imaging cameras. Many infrared cameras do not have this function, and only have the function of center temperature measurement. This type of thermal imaging camera does not automatically track the highest temperature point. If the lens is not aligned with the highest temperature measurement point, the problem will not be captured correctly. Therefore, it is very important to have a movable temperature measurement point and a temperature measurement area.
