Pinhole Security CameraThe pinhole security camera has a very small lens. It may be powered by batteries or a DC power supply. More than one receiver can operate the camera. It transmits images to the receiver when there’s a 60 meter open distance between the camera and the receiver. The pinhole security camera is typically less than 1 inch square. Color Security CameraThe color security camera captures images that help people distinguish grouped items. It’s expensive because it needs too much light to capture good images.

It’s cheaper than the color security camera because it uses little light to capture good images.
