There is a growing demand for CCTV camera installations in both residential and commercial security needs. These cameras work either separately or in combinations with other security solutions like access control or intruder alarm. With the analog camera systems becoming outmoded, consumers find CCTV systems the best choice for their security needs. However, both individuals and businesses find it confusing when it comes to selecting the right choice for their security needs.
The Different Types of CCTV Cameras
There are different types, configurations and styles of CCTV cameras available, giving a wide range to select from, depending on their intended applications and needs.
The most common type is the Dome Cameras found in indoor security and surveillance applications. The shape of this type makes it difficult to know the direction of facing of these cameras and is ideal to stop criminals in their nefarious plans. The popularity also derives from three reasons, namely:
Easy installation – there are two or three screws required to install most of the dome types. Also, these cameras can be mounted easily on both horizontal and vertical surfaces like walls and ceilings.
Vandal-proof feature: The hardened plastic casing covering the camera protects it from vandalism.
Infrared Capability: there are some dome cameras that have IR illuminators, making it easy to capture video images in low lighting conditions.
These cameras have long, tapered, and cylindrical shape as found in a “rifle bullet”, giving it the name. These are used for outdoor applications, where there is a need for long distance viewing. These cameras are installed inside protective casings, protecting them against dirt, rain, hail, dust and other harmful elements. There is a mounting bracket that helps to point the camera in a desired direction. These cameras are fitted with either fixe or varifocal lenses.
These have detachable lenses that allow users to change lenses according to the need of the applications. For example, the standard CCTV camera lenses can keep an eye between 35 and 40 ft distance, while a C-mount camera using special lenses can cover distances further than that.
These types can work in both normal and faintly-lit environments. As these cameras have an extra sensitive imaging chip capable to capture clear video images in the dark, there is no need for inbuilt infrared illuminators. This makes this camera an ideal choice for outdoor surveillance applications, where IR cameras do not function optimally.
