disappointed! a focal optics with a very small angle (not wide) it is more zoomed in, so, in the entry, it takes only a small part of the room instead of having a whole . very mediocre if not part VERY clear. if a subject is presented to 4m, it only takes her bust. it is better to invest in qqchose more expensive but more compatible surveillance. self triggering works well, besides the camera works well, it's just that it's not suitable for job
