Check the listing for details. Bosch LTC 3293 / 40 Auto Iris Motorized Zoom Lens w Bosch Color Security Camera. Condition: Used. Listed at 439.99 USD. This is an incredible security camera / lens. The last pics in the listing show it hooked up to my security system which are of a car wash that is a little less then a quarter mile away from where my system is. It was at night time so the pics do not do its capability justice, but I will try to add more when there is daylight. The very last picture shows the distance from the camera system to car wash. Also the quality of the pics as far as clarity goes is not great because of the multiple forms of camera / video, it being dark out, and the camera is behind a window, but in person it is much better.
