When people in Paphos decide to install an alarm, the first question they ask us is almost always the same: wireless or wired? Both can protect a home properly. The right choice depends on whether the house is already lived in, whether there are cables in the walls, and how you want to control the system.
How a wired alarm works
In a wired alarm every motion sensor, door contact and siren is connected by cable to a central panel. The cables run through walls, ceilings or trunking. The panel powers every device, so there are no batteries in the sensors.
- Strengths: no sensor batteries to replace, and a solution proven over many years.
- Limits: installing in a finished home means drilling, trunking and often repainting. Extending the system later is harder, because each new sensor needs a new cable.
A wired alarm mainly suits new builds, where cables are planned from the start together with the electrical installation.
How an Ajax wireless alarm works
In modern wireless systems such as Ajax, sensors talk to the central Hub over encrypted radio. Each device has its own long-life battery, and the system warns you well before it runs low.
- Fast installation with no dust or damage, ideal for homes that are already lived in.
- Easy to extend: add a sensor, a photo-verification detector or a smoke detector whenever you want.
- Alerts on your phone for every alarm, arming and disarming event, through the app.
- Backup connections: depending on the model, the Hub can communicate over Ethernet, WiFi or a SIM card.
The main limit is that batteries will eventually need replacing. In practice this happens rarely, and the system tells you exactly which device needs it.
Which is more reliable?
A properly installed system, wired or wireless, is reliable. What really makes the difference is design: the right position for each sensor, every entrance covered, sensitivity set so pets or curtains do not cause false alarms, and the signal checked in every part of the house before handover.
Hybrid: the best of both
Many homes in Cyprus already have an old wired alarm. In these cases you often do not need to throw everything away. With the right module, existing wired sensors can connect to an Ajax system, and wireless devices can be added where coverage is missing. You get the app and modern features while keeping whatever still works well.
What else your alarm can protect
A modern alarm is not only about burglary. In the same system you can add:
- smoke and heat detectors,
- water leak sensors and valves that shut off the supply,
- a panic button for elderly relatives or for business premises,
- outdoor sensors for the garden, veranda and pool area.
How to decide
Choose wireless if:
- the house is already lived in and you want no building work,
- you want to extend the system step by step,
- you want full control from your phone from day one.
Consider wired or hybrid if:
- you are building a new home and cabling can be planned now,
- there is already a wired system in good condition.
What to ask before accepting a quote
Whichever option you choose, a proper quote should clearly answer a few questions:
- Which areas are covered, and with which sensors? Ask to see where each device will go.
- How does the system communicate if the power or internet goes down? Is there a backup battery and a SIM card?
- Who receives the alerts? Just you, the whole family, or a monitoring centre as well?
- What happens after installation? Who handles service, battery checks and user changes?
- Can it be extended later with cameras, smoke detectors or automation?
A system that is explained clearly from the start is usually a system you will use properly for years.

Frequently asked questions
How long do batteries last in an Ajax wireless alarm?
Ajax devices use long-life batteries that typically last several years, depending on the device and how it is used. The app warns you well before a replacement is needed.
Can I keep my old wired alarm?
Often yes. With the right module, existing wired sensors connect to an Ajax system and wireless devices are added where needed.
Will I get false alarms if I have a dog or cat?
Pet-friendly motion detectors are available. With the right position and settings, false alarms are avoided.
