Question:
1, Why normal telehoto CCTV camera can not see human 10km? such as telehoto 1000mm, 1200mm etc.

Because their focal length data is not real, their focal length is not pure optics, their lens diameter is too small, their telephoto image is not clear, or their defog is bad;

Such as 1200mm is only 1000mm real focal length, then plus 2x extender said 2400mm focal length, even 770mm-800mm is only 400mm real focal length.

When telephoto image is clear, sharp and crisp with with high color saturation, then, discernment will be multiplied; also, normal long range have fog, especially the sea and the jungle.

2, Why the 2MP camera image is better than some 8MP and even 8K camera?

Because the camera is no chromatic aberration design that image is clear and sharp with high color saturation, including telephoto edge image.

3, Why many 750mm/ 1000mm/ 1200mm focal length CCTV surveillance camera is only used for 3km-5km laser rangefinder?

Because their optical axis can not align target, such as 2mrad accuracy is 2m for 1000m distance and 6m for 3000m distance.

then their camera can not shoot 3km vehicle, so their laser rangefinder task is only roughly measurement.

4, Why the 2MP camera price is much higher than normal CCTV camera?

Because the camera is coaxial zoom with no chromatic aberration, rapid auto, supper defog, wide spectrum, shockproof, compact size and ultra-long life, also image quality can compete with some SLR camera.
