Here’s how we ensure your property remains fully protected against determined intruders:
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.
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.
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.
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.
