Smart security, designed right.

Yes. Every system we install has a mobile app: you arm and disarm, watch live video from the cameras and get real-time alerts, wherever you are.

Yes. The control panel has a backup battery and communicates over both the mobile network and the internet. If the power or the line goes down, protection continues and you are still notified.

As many as you like. Each family member or employee gets their own code or app access, with the permissions you set, and you can see who armed or disarmed and when.

If you're connected to the Monitoring Station, it isn't just a siren. An operator sees the event, checks the video, calls you to confirm and, if needed, dispatches a response. This is what the first two minutes look like:

Within minutes of verification. The monitoring centre operates 24/7 and dispatches a rapid-response team, and the police are notified where needed. You watch live from your phone.

We recommend it. An alarm ringing in an empty house protects no one. With the Station, a person evaluates every signal 24 hours a day, even when you can't answer the phone.

It's a monthly subscription with no commitment, and we connect even systems we didn't install. The exact amount depends on the type of space and the response services, so we give it to you in writing after a short conversation.

It depends on three things: how many entry points the space has, whether you want just an alarm or cameras too, and whether you'll connect to the Monitoring Station. That's why we don't quote blind. We visit for free, see the space and give you a written quote with clear pricing.

One of our technicians visits your space, identifies the weak points, tells you what you need and what you don't, and leaves with everything recorded for a written quote. No charge and no obligation.

Yes. The contract includes an annual preventive check, priority on faults and prompt technical service. It also applies to systems we did not install. Without a contract, we charge per visit.

A wireless home system is usually installed in a day, with no work on the walls. For businesses with several systems, we schedule the work so your operations never stop.

Not necessarily. The wireless Ajax systems we install go in within a few hours with no cabling. In new builds, where we can run cables, we recommend wired or hybrid for maximum reliability.

Usually yes, and it costs less than you think. We keep the detectors and wiring that still work and replace the control panel, so you get phone control and operation during power cuts. See in 2 minutes how well your current system protects you:

Whatever works properly, yes. We test every detector and siren for free and replace only what leaves you exposed. That keeps the upgrade affordable and quick.

Yes, as long as the Data Protection Authority rules are followed: signage, coverage of your own space only, limited retention and informing employees. We guide you at every step and supply the signage ourselves.

Usually 15 to 30 days, depending on the drive and the number of cameras. We set retention in line with the law, so you're covered legally too.

In Pylaia, Thessaloniki, 17is Noemvriou 81. We serve all of Northern Greece and projects across the country.

We are an official Ajax installer with Superior status. We also install Hikvision, Dahua, Paradox, TP-Link, ZKTeco, Teletek and Takex, and always recommend the equipment that suits your premises and budget.

Superior is Ajax's professional line for demanding projects such as jewellery shops, banks and high-value warehouses. It is installed only by certified partners, after training and approval by the manufacturer.

Yes. AT Security is ISO 9001:2015 certified, holds the licence required by Law 2518/1997 for installing and maintaining security systems, and works to European EN standards. We have been in Thessaloniki since 1986.

It depends on the premises. A shop usually needs an alarm with shop-window protection and cameras at the till, an office needs access control, and a warehouse needs perimeter protection and fire detection. After the survey we propose one integrated system with only what you really need.

They recognise people and vehicles and alert you only about them, not about rain, shadows, branches or animals. Alerts drop to the few that matter, and you find an event in the recording quickly.

Yes. Cameras and alarm work together in the same app: when the alarm goes off, you immediately see the image from that spot, and the Monitoring Station verifies the event before dispatching a response.

The alarm keeps communicating over the mobile network, which works as a backup channel. The connection is checked constantly, so if a channel is lost you know straight away, and the Monitoring Station keeps receiving signals.

Not if the right detectors are fitted. There are motion detectors that ignore animals up to about 20 kg, and during the survey we choose the right spots so your home is protected without false alarms.

In many business premises fire detection is mandatory and set out in the fire safety study. We install systems to EN 54 standards. At home, wireless smoke, heat and carbon monoxide detectors warn you early and send an alert to your phone.

With leak sensors at the risk points, such as under washing machines, water heaters and sinks, and a shut-off valve that closes the supply automatically as soon as water is detected. You get an alert on your phone right away, wherever you are.

It is a way to decide who enters, where and when, without keys: with a card, code, phone, fingerprint or face recognition. You see the entry log and can cancel access instantly, and in businesses it can also link to time tracking.

Yes. The systems we install can be expanded: you can start with the essentials and later add cameras, detectors, fire detection or flood detection without replacing the system.

It is your personal page on our website. You see your system and its zones, visit history, agreements and warranties, download user manuals and request a technician. Access is granted after approval, with a personal password.
