Choosing the right CCTV cameras and installation considerations!

The very mention of ‘home security and surveillance’ will ship one to the terrain of the ‘CCTV camera’. In the present state of affairs, where home burglaries and crimes have seen a steep rise, staying secured and protected is the need of hour. Thanks to advancements in technology; easy availability of sophisticated security and surveillance systems and their installation lets you exploit solutions to your advantage. What matters is taking the right installation decisions – the type of CCTV camera to be installed inside the home and exteriors, whether analog or IP (internet protocol) based camera, whether stationery or moving. In case of IP based camera, the cameras are placed on the network on any location while the DVR which is also on network can be placed in another location.

How to Choose CCTV Camera for Exteriors:

  • Cameras are specified by TVLs (television lines); recommendation is for 600 TVL though 420 TVL and 500 TVL lines are also available
  • For night vision one should use CCTV cameras with infra red LEDs. Most of the IR cameras come with 26 IR LEDs but nowadays one can get single high power LEDs
  • When cameras are placed in exterior they should be weather proof. This can be specified by the IP code level (ingress protection rating). Recommendation specification for outdoor cameras is IP 55, IP 60 and IP 65. It is IP 65 that I considered the best specification.
  • For larger exterior spaces, PTZ cameras, which are high resolution cameras that rotate 180 degrees, should be installed.

How to Choose CCTV Camera for Interiors:

  • For residential interiors one can use 500 Plus TVL Lines cameras, for commercial it is recommended to have 600 lines cameras.
  • There are few cameras available which allows the cameras shutter to close when the house owner comes back to house to maintain their privacy. These cameras are preferred for residential purposes.
  • Mostly dome based cameras are used in interiors but there are cameras available which are aesthetically matching your interiors.
  • For night vision it is preferred to have IR based CCTV cameras inside your premises.
  • The cameras have to be mounted either on roof or on the wall at a height where no one can reach them.

Dos and Don’ts for Installation of Security Cameras:

  • Wires of a CCTV camera should be hidden. Exposed wires are prone to get mishandled, which may deactivate the camera
  • It is advisable to install cameras in such a way that they are facing each other so if one is mishandled, the other records the culprit.
  • Recommended height of installation of the security camera should be 10/11 feet
  • CCTV cameras should not be installed below 4 feet in a parapet wall
  • Lens of the security camera should be cleaned regularly depending on dust levels.
  • Ensure that all your entry and exit points are covered by the CCTV cameras.
  • It is advisable to have exterior cameras which is overlooking the approach roads to your facility to ensure recording of any reconnaissance which is generally done by thieves/burglars before striking the site.
