Ajax is a wireless alarm system that protects homes and businesses with no building works and no compulsory monthly fee: sensors detect intrusion and send real-time alerts straight to your phone. It is one of the most popular systems on the Costa del Sol, and ideal for holiday properties. Here is how it works and what it protects.
How an Ajax alarm works
Ajax uses a central hub and wireless sensors — movement detectors, door and window contacts, glass-break sensors — plus sirens. When a sensor is triggered, the hub sounds the alarm and sends an instant notification to your phone. Because it is wireless, it installs quickly with no cables or works.
What it protects
- Homes — main residences, villas and apartments.
- Holiday properties — real-time alerts wherever you are, perfect for second homes.
- Businesses — shops, offices and premises, with sensors for entrances and storage.
No monthly fee (unless you want one)
In the self-monitored setup there is no monthly fee: the alerts come straight to your phone and you decide what to do. If you prefer, optional professional monitoring with a central station can be added. Either way, you stay in control.
Why it is great for the Costa del Sol
Many homes here sit empty for long periods. With Ajax you get an instant alert the moment something happens, so you can react — or call a neighbour or the police — from anywhere. Combined with a good anti-bump cylinder, it gives strong, layered protection.
