All About CCTV Cameras In addition to their Functionalities

Access Control - There exists a growing demand for CCTV camera installations in both residential and commercial security needs. These cameras work either separately or perhaps in combinations with other security solutions like access control or intruder alarm. Using the analog camera systems becoming outmoded, consumers find CCTV systems the best option for his or her security needs. However, both of these people and businesses find it confusing in terms of choosing the right choice for their security needs.

The differing types of CCTV Cameras

There are various types, configurations and designs of CCTV cameras available, giving a variety from which to choose, depending on their intended applications and requirements.

Dome Camera

CCTV - The most frequent type will be the Dome Cameras found in indoor security and surveillance applications. The design with this type makes it hard to be aware of direction of facing of such cameras and it is ideal to prevent criminals in their nefarious plans. The buzz also stems from three good reasons, namely:

Easy installation - there are two or three screws required to install a lot of the dome types. Also, these cameras may be mounted easily on both vertical and horizontal surfaces like walls and ceilings.

Vandal-proof feature: The hardened plastic casing since the camera protects it from vandalism.

Infrared Capability: there are some dome cameras which have IR illuminators, which makes it easy to capture video images in low lighting conditions.

Bullet Camera

These cameras have long, tapered, and cylindrical shape as found in a "rifle bullet", passing on the name. They are used for outdoor applications, where there is a requirement for cross country 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 suggest your camera inside a desired direction. These cameras are fitted with either fixe or varifocal lenses.

C-mount camera

CCTV - These have detachable lenses that permit users to change lenses according to the demand for the applications. As an example, the typical CCTV digital slr lenses will keep an eye fixed between 35 and 40 ft distance, while a C-mount camera using special lenses can cover distances further than that.

Day/Night Camera

This type can work in both normal and faintly-lit environments. Because these cameras come with an extra sensitive imaging chip qualified to capture clear video images at nighttime, there is no need for inbuilt infrared illuminators. As a result this camera a great choice for outdoor surveillance applications, where IR cameras usually do not function optimally.
