Lock Changes and Upgrades
Q: When should I consider changing my locks?
A: If you’ve just moved in, lost keys, had a break-in, or want to improve security, it’s best to replace your locks. We recommend doing so immediately after moving to a new home.
Q: What are British Standard BS3621 locks, and why do I need them?
A: BS3621 locks are tested for strength, reliability, and security. They’re often required by insurers and offer greater resistance against drilling, picking, and forced entry.
Q: Can you upgrade locks on wooden, composite, and UPVC doors?
A: Yes, we carry and fit a wide range of locks suitable for all door types, including mortice, rim cylinders, multi-point locks, and euro cylinders.
Home Surveillance
Q: Do I need Wi-Fi for a home CCTV system?
A: For smart, app-enabled CCTV systems, yes. However, we also offer wired DVR systems that don’t rely on Wi-Fi and are suitable for standalone monitoring.
Q: Can I view footage remotely on my phone?
A: Absolutely. Our smart CCTV systems offer remote access via app, so you can check in on your home anytime, anywhere.
Q: Will the CCTV record at night?
A: Yes. Our systems include infrared night vision so your home is protected and recorded even in total darkness.
Burglar Alarms
Q: Are your alarms suitable for pets?
A: Yes, we offer pet-friendly motion sensors that won’t trigger false alarms when cats or small dogs move around the house.
Q: Can I set zones so only part of the house is alarmed?
A: Definitely. We can configure systems with zone control so you can secure the downstairs at night while moving freely upstairs.
Q: What happens if there’s a power cut?
A: Our systems include battery backups, ensuring your alarm continues to work even during outages.
