When you’re fitting an intruder alarm, one of the first choices is wired or wireless. Both protect your premises well; they just suit different buildings and situations. Here’s the plain-English difference.
Wired alarms
Sensors connect back to the panel by cable. They’re rock-solid and reliable, with no batteries to change in the sensors, which makes them a good fit for larger premises and new builds where cabling can be run cleanly during a fit-out.
- Pros: very reliable, no sensor batteries, well-suited to bigger sites.
- Cons: more disruptive to install in a finished building (cables to run).
Wireless alarms
Sensors talk to the panel by radio. That makes them quick and tidy to install in an existing, occupied premises without chasing cables through walls — ideal for a shop or office already trading.
- Pros: fast, clean installation; easy to add sensors later; minimal disruption.
- Cons: sensor batteries need occasional replacement (the system tells you when).
So which should you choose?
For a building that’s being fitted out or renovated, wired often makes sense. For an occupied premises where you don’t want the disruption, wireless is usually the easier choice. Many sites end up with a sensible mix. The right answer comes from looking at your building, not a rule of thumb.
We fit and maintain both. See intruder alarm systems or ask Bellcom which suits your premises.
