Free security improvements (cost £0)
Before buying any technology, start with these free measures:
- Lock all doors and windows: 30% of burglaries happen through unlocked doors/windows
- Use timer plugs on lamps: a dark house signals nobody's home
- Keep hedges below 1 metre: high hedges give burglars cover
- Don't advertise new purchases: break down delivery boxes before putting them out
- Use the "neighbour effect": introduce yourself to neighbours; watched streets have less crime
- Post on community groups: active neighbourhood watch groups reduce burglary by 16–26%

Frequently asked questions
Is a £50 camera as good as a £200 camera?
In daylight, close. Budget cameras from Tapo, Eufy and Reolink record 2K footage. The differences show in night vision, AI detection accuracy, build materials and the app. For most homes, a £50–£80 camera does the job.
Can I use security cameras without Wi-Fi?
Most smart cameras need Wi-Fi for remote access and alerts. However, cameras with local SD card recording (like Reolink and Tapo models) will still record footage without internet. You just can't view it remotely until the connection is restored. For offline-first options, look at Reolink's 4G LTE cameras.
Are smart security systems easy to hack?
Systems from the major brands use AES-128/256 encryption and two-factor authentication. The usual weak point is a weak Wi-Fi password. Use a strong, unique Wi-Fi password and enable 2FA on all security apps.
