Are wireless burglar alarms secure?
Yes. A professionally installed wireless burglar alarm is secure. Professional systems encrypt the radio signal between sensors and the control panel, check regularly that every sensor is still in contact, and raise a tamper alert if a device is opened or removed. The main upkeep is sensor batteries, which the system reports when they run low.
How does a wireless alarm stay secure?
Each sensor talks to the control panel over an encrypted radio link, so the signal cannot simply be read or copied. The panel also expects to hear from every sensor at regular intervals. If one goes quiet, because it has failed, been removed or lost its signal, the panel reports it.
Every device has a tamper switch. Opening a sensor, pulling it off the wall or interfering with the panel raises an alert in the same way an intruder would.
Can a wireless alarm be jammed?
Professional wireless systems are built with this in mind. Many detect radio interference on their frequency and treat sustained jamming as a fault or an alarm, rather than failing silently. That is one of the main differences between a professionally installed system and a basic self-fit kit.
Signal strength is checked for every sensor position during installation. Thick walls, foil-backed insulation and long distances can weaken a radio link, so positions are tested before devices are fixed.
When is a wired or hybrid alarm the better choice?
Where a property is being built, extended or rewired, cables can go in before the walls are closed, and a wired alarm avoids sensor batteries altogether. Where a sound wired alarm already exists, it can often be modernised rather than replaced, with wireless devices added as a hybrid system.
