Low Cost Interventions
9. Video Doorbells
Video doorbells combine a doorbell with a camera, microphone, and motion sensor, allowing residents to see, speak to, and record visitors remotely via smartphone apps.
These devices deter burglars by increasing perceived surveillance and enabling rapid police response through footage sharing. They are widely adopted in UK neighbourhoods and often integrated into broader smart home security systems.

Effectiveness
Linked to measurable reductions in burglary and doorstop crime, with visible video doorballs leading to 28% fewer attempted break ins.
Visibility is key to success, with glowing LED indicators to deter oppotunistic offenders. They also lead to a 12% increase in arrests, via facial recognition and license plate identification.
They can also create a digital neighbourhood watch with widespread adoption. Effectiveness does depend on visibility, community uptake, and integration with police reporting systems.
