Ring doorbell owners have been warned that they could be fined up to £100,000.

Privacy experts have flagged crucial guidelines, non-compliance with which could result in a massive bill.

The rules overseeing the use of CCTV at home have been highlighted by Max Royston, a director at Gaffsy.

He said: "If your CCTV films or captures images of people outside of your property boundary, like a neighbour's garden or home, shared spaces or public areas, your CCTV must be GDPR compliant."

If these regulations are not abided by, the owner of the camera could be punished by the ICO (Information Commissioner's Office) including fines thay may reach six figures, touching on potential legal challenges from people who appear within recorded footage.

Experts add that, if businesses are in the wrong, they could face huge penalties of up to £17.5million.

To guard against this, it is important for video and data to be stored properly.

Mr Royston added: "Ensuring the data and time is correct is important, in case you need to submit videos for assessment.

"You'll also need to check whether the recorded information is used for the purpose of which your system was installed."

He added that sharing video online could also result in repurcussions, warning: "You could be infringing on privacy rights."

The expert also said: "It's your responsibility to ensure that the system is installed correctly, for all the information recorded by your system.

"You must also ensure that the information gathered by CCTV is not used for anything other than protecting your property."

If you receive a request to delete footage that is deemed an appropriate one, this should be granted, specialists advise.

Further, video footage should only be retained for a necessary period before being deleted. This is typically a few months, Bristol Live reports.

Mr Royston said: "If the CCTV footage is captured outside your property limits, you should only keep the footage for an appropriate period and delete it after a few months.

"You should also delete footage of neighbours if they ask, due to the GDPR rules."
