Dome Cameras

 

Dome cameras are the most used CCTV Cameras in our installations. They normally contain these aspects:

  • In simple terms dome cameras look like half of a football.
  • The dome camera can be wall mounted, pole mounted or ceiling mounted
  • The dome camera can be fixed lens or varifocal. Fixed lens are normal cheaper.
  • The dome cameras are normally made of metal and vandal resistant. They can come in a lightweight plastic form.
  • The metal dome camera allows the camera to be vandal resistant.
  • The dome camera normally provides a colour image. There are also thermal dome cameras available.
  • Most dome cameras these days come with infra red light built in which provide night vision. These only come on when the camera detect low light levels such as night time. (Please bare in mind the image turns black and white with infa red night vision)
  • Enhanced housings are available for dome cameras which can provide increased strength from vandals. Water/Rain resistance. Or for use in specialist environments such as highly toxic environments.
  • Domes can come in many different colours. They can also be spray painted if done properly. (this may void the warranty in some situations)
  • Dome cameras are supported in IP, AHD, Analogue & HD.
  • Dome cameras can run on coaxial or Cat5 (networking) cables depending on the camera purchased.
  • Dome cameras can run on IP networks and the power and video signal can be sent through one cat5 cable therefore reducing the cabling cost. (normal coaxial installations require a separate cable for power)
  • Dome cameras can be mounted on the wall outside but they suffer from issues of rain water falling on them. This obstructs the view in rainy conditions. You can get rain coverings but they are rare with suppliers.
  • Dome cameras can come with bases to hide the connectors so a outside IP rated junction box does not need to be used.
