Award-Winning Wireless Security
Security & Electrical Group Ltd is an authorised Ajax installer, deploying the award-winning Ajax wireless security ecosystem for commercial and residential properties across England. Ajax has redefined what wireless alarm systems can deliver — combining military-grade encryption, exceptional radio range, photo verification of alarms, and intuitive smartphone control in a system that installs in hours without any wiring.
Unlike traditional wired alarm systems that require extensive cabling and days of installation, Ajax devices communicate wirelessly via the proprietary Jeweller radio protocol with up to 2km range. The hub connects to your network and the Ajax cloud, giving you real-time control and notifications from anywhere via the Ajax app. Every component is battery-powered with multi-year battery life, tamper-protected, and encrypted end-to-end.
Ajax is the smart choice for properties where running new alarm cabling is impractical, disruptive, or too expensive — including listed buildings, rented premises, retrofit installations, and sites that need a professional-grade alarm system installed quickly with minimal disruption.

Control Everything from Your Phone
The Ajax app gives you complete control of your security system from anywhere. Arm and disarm zones, view real-time sensor status, receive instant push notifications with photo verification when alarms trigger, manage user access, and review event history — all from your smartphone.
Multiple users can be added with different permission levels — full control for business owners, arm/disarm only for staff, or view-only for monitoring. Group arming lets you secure different zones independently — arming the warehouse while keeping the office accessible, for example.
The app also shows system health — battery levels, signal strength, tamper status, and connection state for every device — so you always know your system is functioning correctly.

Ajax Alarm System FAQs
Yes. Ajax uses military-grade AES-128 encryption on all communications, frequency-hopping to prevent jamming, and tamper detection on every device. The Jeweller radio protocol is tested against all known attack vectors. Ajax systems meet EN 50131 Grade 2 security standards — the same level required for insurance-approved monitored alarms.
Most Ajax devices run on pre-installed batteries with a lifespan of 5-7 years under normal use. The hub monitors battery levels on every device and alerts you via the app when replacement is needed — well before batteries run out. Battery replacement is straightforward and doesn't require an engineer visit.
MotionCam detectors capture a series of photos when motion is detected, sending them instantly to your phone. This lets you see exactly what triggered the alarm — confirming whether it's a genuine intrusion, a pet, or a false trigger. Photo verification dramatically reduces false alarm responses and gives monitoring stations visual evidence to escalate to police.
Yes. Ajax systems support connection to alarm receiving centres (ARCs) for professional 24/7 monitoring. The hub communicates alarm events to the monitoring station via the Ajax cloud, and photo verification from MotionCam detectors gives operators visual confirmation to escalate genuine intrusions to police response.
Most residential and small commercial Ajax installations are completed within a single day. Because all devices are wireless, there's no cabling to run — each device is mounted, paired to the hub, and tested in position. Larger commercial systems with more detectors and zones may take 1-2 days depending on the number of devices.
