  • Q
    What is the difference between a normal lens and an infrared lens?
    Collapse Unfold
    A

    The purpose of the two is different: in the monitoring environment that does not require infrared light subsidies, use ordinary lenses; in the monitoring environment with infrared light subsidies, if you want to have more ideal monitoring effects, you must use infrared lenses, of course, use ordinary The infrared lens can also see the picture under the infrared subsidy, but the picture will become blurred, I believe everyone understands it. Second, the prices of the two are different: the price of professional infrared lenses is several times that of ordinary lenses, why? Because the infrared lens is clear during the day and night, the effect is natural and expensive.


  • Q
    What is infrared imaging?
    Collapse Unfold
    A
    Infrared imaging technology is a promising new technology. Electromagnetic waves longer than 0.78 microns are located outside the red of the visible light spectrum and are called infrared rays, also known as infrared radiation. Refers to the electromagnetic wave with a wavelength of 0.78-1000 microns, where the part with a wavelength of 0.78-2.0 microns is called near infrared, and the part with a wavelength of 2.0-1000 microns is called thermal infrared. In nature, all objects can radiate infrared rays, so using the detector to measure the infrared difference between the target itself and the background can obtain infrared images formed by different thermal infrared rays.
  • Q
    What should I do if the battery power of the camera is too fast?
    Collapse Unfold
    A
    1. The ambient temperature is too low.

    2. The rechargeable battery is not fully charged.

    3. The rechargeable battery is completely depleted and cannot be recharged.

    Solution:

    1. Recharge the rechargeable battery.

    2. Use another rechargeable battery.
  • Q

    A
    1. The ambient temperature is too low or too high.
    2. The rechargeable battery is not fully charged. Recharge the rechargeable battery.
    3. The life of the battery is nearing the end. Generally, this type of battery can be charged and discharged for about 300 cycles.
