What are the rules on CCTV cameras and GDPR

The rules are different for Domestic and for Retail/Commercial. A great source of information for the rules on GDPR in a domestic dwelling is the ICO (Information Commissioner's Office). If your cameras only pick up imagery from within the boundary of your private property then you do not need to worry about GDPR, if your cameras pick up any images from your neighbours, public footpaths or the street, the general GDPR and data protection act of 2018 will apply.

A few things to think about when considering installing CCTV are the following

  • Will I benefit from CCTV?

  • Are there other things I could use to protect my house such as intelligent lighting or better exterior lighting?

  • What is the most privacy-friendly way to set up my cameras?

  • What areas need monitoring?

  • Can I position my cameras on just my property?

  • Do I need to record the images, or should I have just a live feed instead?

  • Has my CCTV system got an audio-recording facility? Audio recording is very privacy-intrusive.

If you do decide that installing a CCTV system is the best way to protect your home then you will need to put up a sign informing people that you have a CCTV system in place

If you are looking to install your CCTV system into a Commercial, Retail or Industrial environment you must adhere to GDPR rules.

As opposed to installing CCTV in a residential application, there are some things you must do regardless of the application.

  • A sign must be displayed explaining that CCTV is in use

  • Delete footage when its no longer required

  • Control the number of people that have access to the footage

  • Clearly state the reason for use

  • Create an employee privacy policy

Are CCTV cameras interchangeable?

The short answer is yes, CCTV camera can be interchangeable, but it might not be worth it.

The adaptability of a system to use a competitors camera on the hard drive will depend on the brand of the system, Most of the leading manufactures will allow competitors cameras on their hard drive.

This said, it's not an easy task and will require a few things.

As an example of this, should you be using something like the Eagle camera system and loading another brand of camera, you will need a laptop and a configuration tool like this one from Dahuawiki .

Are CCTV cameras effective?

The evidence suggests that CCTV can effectively reduce crime. There are however things to take into consideration such as positioning, installation intent, and the CCTV system being used.

It is estimated that overall, for every 100 crimes, an average of 16 crimes were prevented with CCTV (based on 41 studies), specifically for vehicle crime, for every 100 crimes, an average of 26 crimes were prevented (based on 22 studies).  

CCTV appears to be most effective in a car park setting and appears to be more effective in the UK than in other locations tested. Further evidence suggests that CCTV is also very effective in the outskirts of a city, research suggesting it can prevent up to 31 crimes for every 100 crimes intended.
