FAQ

Monitor the important parameters of the lens
In order to make the megapixel camera the best performance, it would be important to use a high-quality megapixel lens, so the quality of the optical image is a key factor in the overall image quality. Megapixel lenses provide high contrast, sharpness and sharpness for the entire image. Rather than megapixel lens can not fully show the megapixel sensor high resolution, especially in the edge of the picture.s
My surveillance camera is not video in the evening, what is the matter?
Your monitor should be infrared. If there is an image during the day, there is no image at night, it may be that the red light will be opened at night and the power supply will be larger than that of the day. But you don't have enough power. Maybe that's the reason.s
Buy surveillance cameras to see which targets
Focal length (f) parameters: the focal length is the distance between the lens and the sensor. By changing the focal length of the lens, it can change the magnification of the lens and change the image size. When the object is far away from the lens, we can use the formula below: the zoom of the lens is approximately the focal length/object distance. Increase the focal length of the lens, enlarge the magnification, and bring the vision closer, the scope of the picture is small, the details of the vision can be seen more clearly. If you reduce the focal length of the lens, the magnification is reduced, the scope of the image expands, and you can see the larger scene.s

5 meters away with the number of mm monitor camera lens appropriate?
