DOME Camera

Dome cameras typically are the best choice whenever possible

  • When the camera is within someone’s reach domes cannot be easily manipulated or vandalized
  • Domes Installs easy in drop ceilings – usually 2 screws
  • Since a dome has a covered lens the direction the camera is pointing is hidden
  • Domes can accommodate infra-red for Night Vision

While Dome Cameras are the installation choice there are limitations. The Dome Cameras themselves are small and then you are limited in lens size.  If you need to focus on a long distance that requires a lens of 50mm focal length or greater it will not fit inside a standard Dome Camera. You get 2 types of  Dome Cameras – Simple plastic ones or metal vandal-proof for public places.

Box Camera

  • When mounting to a wall or any vertical area
  • When viewing long distances where a long lens is required, which would not fit inside a dome or bullet camera
  • When extreme low light conditions are not a consideration

Infra-red Camera

  • When there are extreme low light conditions
  • When the camera is not within someone’s reach

The distance of an Infra-red Camera are based on its illumination capacity. Infra-red Cameras have LED’s, which cast into the darkness.  On the LED’s of a camera a good rule of thumb is (but not absolute) 1 foot for each LED. Save to work out if a camera has 30 LED’s it can probably see about 30Feet. The Quality of an Infra-red Camera is determent on the size of the LED and the distance they cover. Just because one Infra-red Camera  has more LED’s then the other does not mean it can cast a longer distance, there are different strengths in LED’s. Unfortunately, its hard to compare.

 

Bullet Camera

  • When you want the camera to be inconspicuous but not covert
  • When the camera is not within someone’s reach
  • When extreme low light conditions are not a consideration
  • For shorter to middle distances

Bullet Cameras are a smaller type of camera. The types of internal boards and lens is limited on the Bullet Camera.  The picture quality of the Bullet Camera cannot be compared with other more traditional cameras.

 

Spy Cameras

  • Just as they say, these are meant not to be seen and come in all shapes and sizes from a wall clock to a sprinkler head or smoke detector even Nanny Cam’s
  • These are great to keep an eye on your property / belongings / children / workers without them knowing

It is important to check your local laws on Spy Cameras with respect to surreptitious recording.

Wireless Cameras

  • When connection to the digital video recorder is not practical

Remember though wireless is just for the video signal, you still need a method to power the camera. Wireless Cameras can be found in most styles. For the most part Wireless Cameras require a line of sight to function properly. Distance may vary depending upon the strength of the transmitter and the receiver, what other devices are in the same spectrum etc. There are external Wireless transmitters & receivers that can attach to any standard camera to make them Wireless, but the cost is very high.

Pan Tilt Zoom (PTZ) Camera

  • When you want live control of the camera and adjusting the manual pan, tilt or zoom on a fixed cameras is not practical
  • When you want to set up a camera to tour the premises
  • When you want to view several angles from a single camera

PTZ Cameras costs anywhere from 5x – 10x the cost of an fixed camera. The PTZ Camera can not see or record where its not looking.  You cannot Pan, Tilt, Zoom after it has been recorded (this can only be done with a 360 degree camera). Making a PTZ Camera wireless will add thousands of rands to the cost. You can control a PTZ Camera and zoom.

CCTV Camera Categories:

Indoor   vs.  Outdoor Cameras

Indoor and Outdoor camera are the same in terms of styles, size and shape.  The principle difference is outdoor cameras are at a minimum weather-proof.

Issues to consider when installing cameras are

☺       Moisture (Rain/Snow/Frost/humidity)

☺       Dust

☺       Sand

☺       Light Conditions

☺       Affordability

Night Vision and Day/Night Cameras
Infra-red (IR) Radiation – electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of radio waves.  The name means “below red” (Latin Ínfra – “below”), red being the colour of visible light of longest wavelength.

Infra-red Cameras is used in night-vision cameras when there is insufficient visible light to see an object.

Day/Night Cameras -  a sensitivity enhancement technology which improves light sensitivity of a camera. It still cannot work in near zero light as will an infra-red camera.

I know what you thinking “It sounds so expensive” both those types of cameras have become commercialized and are surprisingly affordable.  The difference in price for one of these cameras versus a traditional camera is normal.

If you would like to know how to choose between a Infra-red & Day/Night Camera if you walk the area where you intend for the camera to be and view it at its lowest possible lighting, if you can see with the naked eye, then the Day/Night Camera should be fine. If you cannot see, then an Infra-red Camera would be recommended.
