Miniature CCTV cameras or pinholes or needles the size of a matchbox are the most common type of hidden CCTV cameras, the main feature of which is its small size. This hidden CCTV camera has small dimensions (about 3 by 3 cm) as well as a fixed lens and a microphone to receive sound from the desired environment. PinHole CCTV camera (or needle lens CCTV camera) due to the small size of the body and small lens, it is possible to record images wherever you want, even from a 3 mm hole.

Miniature CCTV camera applications
Due to the small size of the body, it is usually used in spaces where there is a need to view and receive images imperceptibly or there is not enough space for a bolt or trap camera, for example in previous years in vehicles such as buses and trucks. It was not possible to install a camera with a normal or large body, and a smaller camera had to be used, with the needle camera being the best and most appropriate choice. Needle cameras, like other CCTV cameras such as bolt, livestock and industrial models, are not of high quality and are mostly installed for small and well-lit environments (no support for night vision). The body of the miniature CCTV camera itself may not be small, but the lens mounted on this CCTV camera is very small and it is not possible to replace the lens in this type of body.

Miniature CCTV night vision
Due to the type of design and due to the special application, this body can not have IR night vision. The main reason for this is that due to the limited dimensions of the body and maintaining the size of the camera tip where the lens is located, the installation of night vision will not be possible by maintaining the standards of a small camera. To compensate for this weakness, quality sensors are usually used so that this camera can provide good vision in low light and can even be created to capture a good image in a good light environment.

Technology used
