Shop anti-theft system - anti-theft in the camera shop
With the continuous development of the times and the continuous improvement of people's living standards, cameras have become an indispensable product in people's daily life. Cameras are indispensable in daily life, so how to protect the camera store?
Today, I will introduce one of the branches of the shop anti-theft system--the anti-theft of the camera shop.
feature:
(1) There is a single lens that can be replaced;
(2) having a movable reflector structure;
(3) There are five prisms;
(4) framing through the optical viewfinder.
One lens is relative to a dual (lens) reverse (optical) camera. This lens is used for both framing and imaging. When framing, the light incident through the lens is incident on the reflector, and then reflected by the reflector to the pentaprism, and then refracted by the pentaprism, which is observed by the photographer through the optical viewfinder.
When the shutter exposure image is pressed, the reflector is raised (the black in the optical viewfinder), and the light is directly incident on the photosensitive element to complete the exposure imaging. The end of the exposure reflector is lowered.
feature:
(1) no reflector and pentaprism;
(2) Electronic framing;
(3) Non-replaceable lens;
(4) Small and portable.
Because of the long lens and the large size of this kind of camera, an anti-theft system with a separate bracket is required.
Because this type of camera is small,so just a simple bracket is all you need.Like this,
