As any local solicitor can tell you, some of the most bitter legal disputes originate fromdisagreements between neighbors. Whether it’s property boundaries, loud music, or parking spaces, what might initially be minor irritations can gradually lead to a full-blown court battle.

A relatively recent development in neighbor conflicts are clashes centered on home surveillance products, such asCCTV camerasandsmart doorbells. These technologies, which may capture footage beyond the householder’s property, can pit householders against neighbors who feel their homes and private lives are being unfairly spied upon.

Indeed, a UK judgerecently ruledthat a man’s home security system invaded his neighbor’s privacy, and he now faces a fine ofup to £100,000. So what are the privacy implications of this technology, and what do people need to know if they have, or are considering installing a smart doorbell?

The use of surveillance technologies is governed by a range of measures. Some provide advice and guidance, like the surveillance cameracode of practice, which sets outprinciples for operatorsto follow. Others are legal requirements, such as the rules for collection and processing of personal data under theData Protection Act 2018and theUK General Data Protection Regulation(GDPR).

These measures aim to ensure that any use of surveillance technologies is for legitimate purposes, proportionate, and compliant with relevant legal obligations. A key concern is that surveillance should, as far as possible, be with the informed consent of those surveilled.

Where do smart doorbells fit in?

Purely “domestic use” of personal data by a private individualis exemptedfrom the data protection legislation – for example, your list of addresses for sending Christmas cards. But it’s well established that home surveillance systems, including CCTV and smart doorbells, are subject to UK data protection legislation.

Akey casein 2014 looked at the use of a home CCTV system by a Mr. Ryneš in the Czech Republic. The Court of Justice of the European Union (CJEU) held that while Ryneš’s CCTV system was installed for a legitimate purpose – the protection of his property and personal security – the data collection went beyond that permitted solely for domestic use. This is because it collected personal data from a public space, including a footpath and the entrance to his neighbor’s house opposite.

With this ruling, the CJEU confirmed that domestic surveillance systems fall within the scope of the data protection legislation where they capture data beyond the boundaries of the homeowner’s property. This interpretation remains applicable under UK law for now, although the UK government could potentially alter the scope of the “domestic exemption” now that the UK has left the EU.

While this caseand othersthat have followed since didn’t involve smart doorbells specifically, the principle is the same. The case ofFairhurst vs Woodardin the English County Court in October 2021 reinforces the view that the courts are likely to take a dim view of those who fail to use home surveillance equipment in a way that respects the rights of other people, including their neighbors.

Woodard installed a range of surveillance technology, including CCTV cameras and a smart doorbell, for home security purposes. But these could record video and audio well beyond the boundaries of his property. He then actively misled his neighbor, Fairhurst, as to how and when the cameras operated. The court found Woodard to have breached his data protection obligation to process data in a lawful and transparent way, and to have collected personal data without a specified or lawful purpose, as required by the Data Protection Act 2018 and the GDPR.

The court did recognize that home security could be a legitimate purpose for collection of data that would otherwise breach a neighbor’s right to privacy if the collection was reasonable and proportionate for that purpose. For example, in relation to Woodard’s Amazon Ring doorbell, the court held that capture of incidental personal data (such as video of Fairhurst walking past) was permissible. However, the capture of audio at a significant distance exceeded what was reasonable for the purposes, as did the fact the system’s viewing range recorded large areas of Fairhursts property, including her side gate, garden, and parking space.

It’s worth noting that Woodard’s use of his home surveillance system, and his interaction with Fairhurst concerning that use, also led to a successful action for harassment against him.

Some tips

If you’re considering installing a home surveillance system, such as a smart doorbell, you should:

TheInformation Commissioner’s Officehas also produced some helpful advice for people installing home CCTV systems.

Pleasingly, providers are becoming more aware of the risks and requirements of home surveillance technologies and are building in new features which may encourage lawful use. For example, Amazon has recently addedend-to-end encryptionto its smart doorbell technologies. This aims to keep personal data captured secure against misuse by third parties by restricting access to video and audio streams to specified devices and permitted users.
