Says: I always advise retailers to make the best use of the security they have. CCTV can be one of the most important parts of a retailer's security strategy, but it can only ever be a part.

Retailers can also make several mistakes when installing CCTV. They often think it is going to solve all their crime problems. But even if CCTV is right for your shop, there are a number of pitfalls. For example, cameras can be poorly positioned and retailers may get advice on installation from sales staff from a particular CCTV company, rather than an independent consultant. Sometimes retailers do not make recordings easily accessible to the police. Another error is failing to monitor the system regularly to see how it is performing.

It is important to note that it is hard for retailers to get funding for CCTV. So shopkeepers should start by getting a proper understanding of what their problem is so they can take cost-effective measures.

Ultimately, be clear what the problem is. Do not just jump to installing CCTV if there are less expensive routes you can take.
