Free Security Improvements (Cost £0)
Before buying any technology, these free measures make the biggest difference:
- 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, surprisingly close. Modern budget cameras from Tapo, Eufy, and Reolink produce excellent 2K footage. The main differences are in night vision quality, AI detection accuracy, build materials, and app polish. For most home security purposes, a £50–£80 camera does the job well.
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?
Modern systems from reputable brands use AES-128/256 encryption and two-factor authentication. The main vulnerability is weak Wi-Fi passwords, not the devices themselves. Use a strong, unique Wi-Fi password and enable 2FA on all security apps.
