Description

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere.

Types of CCTV Cameras 

  • Dome CCTV Cameras
  • Bullet CCTV Cameras
  • C-Mount CCTV Cameras
  • PTZ Pan Tilt & Zoom Cameras
  • Day/Night CCTV Cameras
  • Infrared/Night Vision CCTV Cameras
  • Network/IP CCTV Cameras.
  • High Definition (HD)CCTV Cameras

Dome CCTV Camera

The dome camera is one most commonly used for indoor and outdoor security and surveillance. The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of uncertainty. Other benefits of this type of camera include:

Other benefits of internal and external dome cameras include:

  • Ease of installation.
  • Vandal- resistant features.
  • IR night vision.

 

Bullet CCTV Camera

Bullet cameras are long and cylindrical in shape and are ideal for outdoors use. Their strengths lie specifically in applications which require long distance viewing. Installed within protective casings, the camera are shielded against dust, dirt and other natural elements. The cameras can easily be mounted with a mounting bracket, and come fitted with either fixed or varifocal lenses depending on the requirements of its intended application.

Other benefits of bullet cameras include:

  • IR night vision.
  • Compact size aids installation.
  • High-quality image resolution.

C-mount Camera

Coming with detachable lenses, C-mount cameras allow for simple lens changes to fit different applications. C-mount cameras can cover distances beyond 40 ft thanks to the possibility to use special lenses with these cameras, whereas standard CCTV lenses can only cover distances of 35-40 ft.

Other benefits of C-mount cameras include:

  • Can support changes in technology.
  • Effective for indoor use.
  • Bulky size makes them noticeable (which acts as a deterrent).

PTZ Pan Tilt & Zoom Camera

PTZ – Pan/tilt/zoom – cameras allow the camera to be moved left or right (panning0, up and down (tilting) and even allow the lens to be zoomed closer or farther. These cameras are used in situations where a live guard or surveillance specialist is there operating the security systems.

Other benefits of PTZ cameras include:

  • 200m IR night vision.
  • x36 optical zoom.
  • High-quality image resolution.

Day/Night CCTV Camera

Capable of operating in both normal and poorly lit environments, these cameras benefit from not requiring inbuilt infrared illuminators as they can capture clear video images in the dark thanks to their extra sensitive imaging chips. For this reason, these cameras are ideal for outdoor surveillance applications in which IR cameras are unable to function optimally.

Other benefits of day/night cameras include:

  • Record in both colour and black & white.
  • Wide variety of sizes available.
  • Infrared capability.

Infrared CCTV Cameras

One of the best 24 hour surveillance cameras around providing airports, seaports, boards and many other critical infrastructures with quality images, no matter what time of day it is. Infrared cameras have small LEDs surrounding lens to help pick up moving figures in pitch black. Thermal image cameras can see over long distances, up to 300 metres away!

Other benefits of infrared cameras include:

  • Detect intruders up 250-300 metres away.
  • Good in low-light.
  • Thermal radiation passes through visual barriers.

Network CCTV Cameras

These cameras share the images across the internet, so CCTV footage can be easily accessed. Network cameras are ideal for both domestic and commercial purposes because you can see what’s going on whilst away from the property.

Other benefits of network cameras include:

  • Data can be easily accessed.
  • Ideal for homes and companies.
  • Less cabling and less maintenance.

High Definition CCTV Cameras

High definition cameras have such a high resolution that they are mainly used in high risk establishments such as banks and casinos. This is to capture a good image of anyone who enters and exits to maintain high security and maximum safety. These cameras are great for spotting misconduct and allows the user to zoom in for extra clarity, should the footage need to be used in count.

Other benefits of high definition cameras include: 

  • Clear, detailed pictures.
  • Offer maximum safety for high risk establishments.
  • Can zoom in without losing focus.
