The system continuously monitors your property. Sensors detect any unusual activity, such as forced entry or movement, and send a signal to the control panel.

Upon detecting a potential security breach, the alarm is triggered. Simultaneously, an alert is sent to your smartphone, and if connected, to our monitoring center.
Remote Access
You can access the system remotely through the app, allowing you to arm/disarm the alarm, check the status, and even view live footage if integrated with CCTV.

Choosing the Right Grade for
Your Security Needs

Bell's High-Security Systems
Here’s how we ensure your property remains fully protected against determined intruders:
Grade 4 High-Security
Digi Modems
For the highest level of security, our Grade 4 Digi Modems maintain constant communication with the central monitoring station. If there’s any interruption, an immediate alert is triggered, and this information can be passed on to the Police or a security response team for swift action.
GSM Modem Backup
Determined intruders may try to cut the telephone line to prevent alarm signals from reaching your mobile app or our central monitoring station. Our GSM modem uses the mobile network, making it immune to such tampering, ensuring signals always get through.
Signal Jamming Detection &
Frequency Switching
Sophisticated intruders might attempt to jam alarm signals to disable the system. Bell Security alarms are engineered to detect signal jamming and can switch to a different frequency, keeping every device in perfect working order.
Backup Sounder with Independent Power Supply
If an intruder tries to smash the main alarm before it can sound, our high-security backup sounder is ready to activate. With its own independent power source, this sounder can continue to alert even if the main system is damaged.
