About CCTV Cameras And Their Functionalities

Home Alarms - There is a growing need for CCTV camera installations in both commercial and residential security needs. These cameras work either separately or even in combinations along with other security solutions like access control or intruder alarm. Using the analog camera systems becoming outmoded, consumers find CCTV systems the best choice for security needs. However, both of these individuals and businesses think it is confusing with regards to selecting the right option for their security needs.

The differing types of CCTV Cameras

There are different types, configurations and designs of CCTV cameras available, giving a variety to pick from, according to their intended applications and requires.

Dome Camera

Access Control - The most frequent type may be the Dome Cameras found in indoor security and surveillance applications. The shape of this type makes it challenging to be aware of direction of facing of those cameras and is also ideal to prevent criminals inside their nefarious plans. The popularity also derives from 3 good reasons, namely:

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

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

Infrared Capability: there are a few dome cameras which have IR illuminators, rendering it an easy task to capture video images in low lighting conditions.

Bullet Camera

These cameras have long, tapered, and cylindrical shape as present in a "rifle bullet", creating the name. These are useful for outdoor applications, where there can be a requirement for long-distance viewing. These cameras are installed inside protective casings, protecting them against dirt, rain, hail, dust along with other harmful elements. There exists a mounting bracket that assists to suggest the camera in the desired direction. These cameras are fitted with either fixe or varifocal lenses.

C-mount camera

Security Products - These have detachable lenses that enable users to alter lenses based on the necessity of the applications. For instance, the standard CCTV digital slr lenses are able to keep an eye 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 be employed in both normal and faintly-lit environments. Since these cameras come with an extra sensitive imaging chip competent to capture clear video images at nighttime, there is no need for inbuilt infrared illuminators. This will make this camera a great choice for outdoor surveillance applications, where IR cameras do not function optimally.
