Security Camera King has a full selection of hidden camera equipment to satisfy your needs. Modern technology has resulted in a tremendous variety of disguised and hidden camera equipment. As a matter of fact, the smallest hidden camera that we offer for sale is the size of a Phillips head screw!
How does hidden camera equipment work? The following is a brief explanation.
First the camera must have a lens. The lens’s duty is to gather the light reflected by the objects in its field of view and focus them onto a sensor chip no larger than 1/4 to 1/3 inches square. Most often but not always, hidden cameras use 3.7 mm wide angle lenses.

Almost all the security cameras these days are digital security cameras. Compared to their old analog equivalents, they are lighter, more efficient, use less electricity, and just about anyone can install them.
Digital security cameras are a small-package of technological wonders from the lens to the video transmission type it uses. In addition, digital security cameras get to “piggy back” on the personal computer industry; that is many times a device is advanced technologically for a computer; the digital security camera industry can reap the benefit of the advance as well.
