SPRO is a leading brand of video surveillance technology products!

Historically old CCTV systems were used to monitor and identify people after an incident had occurred.

With the new Active Deterrence cameras CCTV systems can now be proactive in preventing a possible crime taking place.


  • PLUG & PLAY: All cameras are connected via the Co-Ax cable running for the DVR Recorder, then just add power to each camera and you have your CCTV set up and ready to use.
  • SECURE RECORDING: Feel safe in the knowledge that your footage from the cameras are safely stored within the recorder with easy access when you need.
  • COLOUR NIGHT: Utilising the power of Starlight technology, the ColourNight range of cameras incorporate a high powered led that will illuminate a surrounding area. This light can be programmed to come on when dark acting as a flood light.
  • ACTIVE DETERRENCE: Actively Ward off potential intruders in real time with built in Smart Motion detection, Tripwire, Intrusion, Object Perimeter protection, facial detections and recognition. 
  • MOBILE APP VIEWING: View and use your CCTV system remotely from anywhere in the world and have access to tools such as playback, two way talk, set alarm and much more!
