Frequently asked questions
What customers ask before booking.
Do all alarm systems require monthly monitoring?
No. Some systems can operate as local or self-monitored alarms, while professional monitoring is available on compatible platforms. We explain the difference before equipment is selected.
Can an old alarm system be upgraded?
Often yes. The panel, wiring, contacts and sensors must be assessed to determine what is safe and compatible to reuse.
What sensors are commonly included?
Door and window contacts, motion detectors, glass-break sensors, keypads and sirens are common. The property layout determines which devices are useful.
