Common questions to ask
when buying a CCTV System:

There are a number of brands which are synonymous with security and surveillance. Check with your provider for a list of top brands that can meet your needs.

  • Storage format of video files.
  • Compression of video files.
  • Ability to add back-up, e.g. microSD cards.
  • Indoor or Outdoor suitability.
  • Do you wish/need to capture sound.
  • Level of resolution you wish to capture e.g. to read registration plate or see broad movements.

There are some camera models which are specifically suited to lower-lighting, they are often referred to as “Low-light cameras”. Infrared cameras can be a great alternative in darker areas, where they will detect heat and provides a thermal image on the video monitor.

Wide-angle cameras can be a great way to capture a more expansive area, these are often popular when capturing an outdoor area.

The video files might be stored in very compressed file sizes (H.265 standard) or less compressed (H.264) or the least compressed (Mpeg). The higher the compression, the more expensive the camera is likely to be.

  • Analog cameras tend to be most affordable, but it's worth taking into account that they may typically capture low resolution imagery or footage.
  • HD Cameras are now becoming a lot more affordable, and provide much higher image quality and clarity. With a HD image, you can zoom in to get more granular detail about the subject in your picture.
  • IP Based cameras are connected to the home or office and can provide live-streaming of content to you via your smart phone or device, wherever you are.
  • Analog cameras are required to be connected to the DVR over cables; so in case of an 8-channel DVR system, 8 cables are attached, one to each camera. In case of an IP based system, the cameras are connected to the NVR over ethernet and so any number of cameras can be connected/expanded over the network, depending upon the bandwidth requirement.
