Shopping For the Right Camera in Retail Security

Shrinkage is a fact of life for retailers. But monitoring it requires a multifaceted approach when it comes to security technology. Paul Murphy, marketing manager at IndigoVision, draws a distinction between shoplifting and theft by employees. "Dealing with shoplifting has different requirements to employee theft. With internal theft it can be more slight of hand so camera resolution is key. They could, for example, scan one thing but take a higher value item through. Here you need to have the quality of video evidence and also integrate with the EPOS (Electronic Point Of Sale) systems for trend analysis to pick-up, for example, if one member of staff does more zero value transactions than others," says Murphy.

Another element for camera deployment, emphasises Murphy, relates to retailers with multiple sites where there may be central monitoring: "If you are looking to distribute and pull back video then you need to think about the bandwidth that is being used on the camera and the type of compression." Added to this, Murphy says, it is not just a question of resolution and video quality: "You need to factor in the frame rate as well when talking about recorded video for evidential purposes. If a camera has too a high bandwidth or storage requirement then people will say to lower the resolution and frames per second. The issue with this is that the evidence you may then want to use in conjunction your EPOS system can be compromised," explains Murphy.
