Case Study: The Silent Sentry
A large rural property in Leeds was a constant target for fuel theft. We installed a PowerG long-range wireless alarm system with perimeter beam sensors. When intruders cut through a fence line 500 meters from the main house, the silent alarm notified the owner's phone instantly. He was able to call the police while the intruders were still in the field, leading to an on-site arrest before they reached the storage tanks.
"The range of the wireless sensors is incredible. It's the first time we've felt truly secure on such a large site."

What is Grade 2?
In the UK, Grade 2 is the industry standard for residential and small commercial properties. It means the system is designed to deter intruders with 'limited knowledge' and a 'limited set of tools.' It is the minimum standard required by most insurance companies.
Insurance Approved
Our Visonic and PowerMaster systems meet strict European standards (EN50131). Don't risk your insurance claim with budget, uncertified DIY alarms.
Anti-Masking Tech
Sensors that alert if an intruder attempts to spray or cover them.
Anti-Jamming
Encrypted wireless signals that cannot be blocked by RF jammers.
Back Tamper Protection
Instant alarm if a sensor is pulled off the wall.
Advanced PowerG Technology
Our systems use PowerG technology, offering a wireless range of up to 2km. This means we can secure large properties, outbuildings, and detached garages with a single central hub, all while maintaining a 5-8 year battery life on sensors.
Case Study: The Foiled Attempt
An intruder attempted to force open a rear window at a property in Huddersfield. The shock sensor triggered the external siren immediately, waking the neighbors and sending a push notification to the owner's phone. The intruder fled before even entering the property. The owner was able to check their LJB cameras on the same app and provide the footage to the police.

Alarm FAQs
Answers to common questions about intrusion systems.
Do you offer wireless alarms?
Yes! Our modern Grade 2 wireless alarm systems are incredibly reliable and require zero cabling through your walls, meaning a clean installation that doesn't ruin your decor.
Will my pets trigger the alarm?
No. We use advanced 'Pet-Immune' sensors that can distinguish between a human intruder and an animal (typically up to 25-30kg), allowing your pets to roam freely while the system is armed.
What happens if the power goes out?
All our alarm systems include a built-in backup battery that keeps the system fully operational for up to 12-24 hours during a power cut, ensuring your security is never interrupted.
