2. Product advantages
In the civilian area, the product can replace the traditional low-light night vision device, and has
a particularly significant advantage: It can be used day and night . It can take color
photos/videos at daytime and black and white photos/videos at night. The image brightness
is regulated through the circuit with good infrared ability. In the black conditions, it can be up to
400 meters effective observation distance. It can record the pictures, the video time is accurate,
and it has long-range real-time infrared monitoring and a long service life.
Ordinary low-light night vision device can't be used during the daytime; otherwise the night
vision tube will burn. The effect is poor with low resolution, the effective resolution is only 24
line pairs, it is not sensitive to infrared, and plus infrared it is maximally up to 40-50 meters.
Internal high voltage boosted circuit is prone to failure, and its reliability is poor and glass tube
is fragile. Low light tube is not high temperature resistant and so the life is short, and the
magnification is small.
3. Applicable and use
