The move to distribute the £89 Ring devices has, however, raised Big Brother fears about the close relationship between a private company and the police.

The internet-enabled doorbells are triggered by movement and begin recording as someone approaches the front door, with the householder notified via mobile.

The company - reportedly bought by Amazon for $1 billion - and the police said the devices deter intruders and capture evidence that helps bring criminals to justice.

Four forces - Suffolk, Leicestershire, Humberside and Hertfordshire - have been given the devices to pass on to residents, the Sunday Times reports.

Another five have promoted the all-seeing doorbells with money-off vouchers or discount code with others reportedly in talks with Ring.

All 43 forces in England and Wales were asked whether they were working with Ring.
