1, DKL equipped with special wave filters can remove other human beings like human beings, such as dogs, cats, cows, horses and pigs, so that DKL life detectors can only sense the electric field generated by human beings.
2. Effective distance: 20-500 meters;
3. Vertical angle:
When there are no obstacles: 60 degrees up and down, a total of 120 degrees;
Obstacles: 40-50 degrees up and down, totaling 80-100 degrees;
Horizontal detection angle: 2 degrees left and right, totaling 4 degrees.
