Alarm & intrusion systems
Motion sensors, door and glass-break detectors, and panic buttons.
An intruder alarm registers entry and movement inside a building while the site is armed. Motion detectors cover the interior, while door and window contacts and glass-break detectors cover the perimeter, the line an intruder crosses first. The control panel reads those signals, sets off the siren and sends the alert to the owner's app. Panic buttons, which a person presses deliberately, and water-leak detectors connect to the same panel, so an intrusion and an incident of another kind in the building both arrive through one channel.
There are only so many ways into a building: a door, a window, a roof light, a shared balcony, a basement entrance. That list is what settles where the protected line runs and what covers each opening, whether a door contact, a glass-break detector, or a motion detector aimed at exactly that stretch. Where a detector sits matters no less than which detector it is: ceiling height, glazed walls, warm air rising off a heater and a pet moving around a flat are the commonest causes of a false alarm. A false alarm is not merely noise, because after a few groundless activations people stop reacting to the siren and the site stops being armed, and that is how a building ends up unprotected. The system also needs a standby supply for a mains failure and an alert path that still works when the internet connection drops.
An office stands empty at night, a warehouse over the weekend, a shop after closing, and in those hours a building depends on nothing but what is installed in it. After handover what stays on the site is a zone plan, a programmed panel and an app on the owner's phone, and that is what works while there is nobody in the building. Arming and disarming codes are issued to each user separately, so the log shows who took the site off guard and when. The real measure of an intruder alarm is not the number of detectors it carries but the number of nights the site is genuinely armed.

Standards and regulations
The requirements for intruder alarm systems are set out in the EN 50131 series, which assigns the system a security grade from 1 to 4 and an environmental class. The grade reflects how prepared and how well equipped an attempt at entry the system has to withstand, and the environmental class reflects where the equipment sits: a building with heating, an unheated warehouse or the open air. Those two decisions determine how many detectors a zone needs and of what type, while the requirements on the panel, the detectors and the warning devices themselves are set out in the parts of the same series. Alarm transmission, meaning how the signal leaves the building, is covered by the EN 50136 series, and electromagnetic immunity and environmental testing by the EN 50130 series. In Georgia the requirement for an intruder alarm comes from several directions: the security policy of the owner or the company, insurance conditions, and in some cases rules laid down for a particular type of premises, so what applies to a specific building is checked at the consultation stage against the regulations in force.

Frequently asked questions
How much does intruder alarm installation cost?
The price depends on two numbers: how many openings have to be covered, meaning how many doors, windows, glazed walls and roof lights sit on the protected line, and how many zones the site is divided into. A panel carries a fixed number of zones, and while the design stays inside that limit each extra detector adds only its own price, whereas crossing the limit calls for an expander module or a second panel and the cost moves up a step. That is why the openings are counted and the site divided into zones before the cost estimate, not the other way round.
Wired or wireless alarm system, which is better?
A wired system is more robust and takes its power centrally, but it needs cable routes, which makes it a natural fit during construction or renovation. A wireless system goes into a finished interior with no additional building work, at the cost of periodic battery changes and signal checks. On many sites the two are combined: a wired perimeter, with wireless devices where cable cannot reach.
Can I control the alarm system from my phone?
Yes. The panel links to an app that shows whether the site is armed or disarmed, which zone triggered and when, and the site can be armed and disarmed from there as well. The alert reaches you even when you are out of the country. For that to be dependable the site needs a stable internet connection, and the panel needs a standby power supply.
Do security cameras replace an intruder alarm?
No, they answer different questions. A detector registers the event at the moment of entry and raises the alarm immediately, while a camera shows what actually happened. When the two work together, the alarm signal is tied to a specific second of the recording, which makes a false alarm far easier to tell apart from a real one.
