Knowing the different kinds of security cameras must be your first priority before purchasing one of them. Vandal proof Security CameraThe vandal proof security camera is the best security camera system for home. It cannot be tampered because it does not have exposed wires. The wires are tucked inside the camera’s covering. Its lens is covered with a thick layer of protective polycarbonate plastic or glass. The protective plastic or glass encloses the camera to prevent people from breaking it. The camera may be weatherproof so that it can be used for outdoors. 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.
