Burglar Alarm FAQs
How much does a burglar alarm cost?
The cost depends on your property size, the level of protection required, and whether you choose a monitored system. Our basic audible-only systems start from £499, while fully monitored systems with police response start from £899. We offer a free, no-obligation security survey to provide a detailed quote tailored to your needs.
Will my pets trigger false alarms?
No — our modern systems include pet-immune motion detectors that distinguish between human movement and pets up to around 38kg. We can also configure zones to exclude areas where pets roam, keeping false alarms to a minimum without gaps in your security coverage.
Do I need a landline for a monitored alarm?
Not necessarily. While traditional systems used landlines, modern alarms connect via mobile networks (4G/5G), broadband, or hybrid solutions combining multiple paths — so your alarm stays connected even if one method fails.
How quickly can police respond to an alarm?
With a URN-registered police response system, verified activations receive priority dispatch from South Wales Police. Response times vary with police resources and location, but URN alarms are always prioritised over unverified activations.
