Intrusion Detectors — Security Sensors in Tbilisi
Intrusion Detectors are core components of security alarm systems that detect unauthorized entry, motion, door/window opening, or glass breakage and immediately send signal to alarm panel in Tbilisi and throughout Georgia. These sensors create invisible protection barrier in your home, office, shop, or warehouse and provide 24/7 monitoring, enabling quick response to intrusion attempts and preventing theft, vandalism, and property damage. LAGI offers full range of intrusion detectors: PIR motion detectors (passive infrared, 110°-180° viewing angle, 10-15m radius, pet-immune), door/window magnetic contacts (reed switch, NO/NC), glass break acoustic detectors (9m radius, frequency analysis), combined PIR+MW detectors (dual technology, false alarm reduction), outdoor PIR detectors (IP65 weatherproof, anti-vandal), vibration detectors (wall/window break), wireless 433MHz/868MHz and wired models. All detectors ensure high accuracy and reliable operation.
Main Types of Intrusion Detectors
- PIR motion detectors — passive infrared sensor, 110°-180° viewing angle, 10-15m radius, pet-immune (ignores pets <15kg), anti-tamper, ideal for indoor spaces.
- Door/window magnetic contacts — reed switch, NO/NC contacts, 10-25mm distance, surface/recessed mounting, cheap, ideal for all doors and windows.
- Glass break acoustic detectors — detect glass break frequency (100-15000Hz), 9m radius, one detector for multiple windows, false alarm filter.
- Combined PIR+MW detectors — PIR (infrared) + MW (microwave) dual technology, both sensors must trigger → false alarm minimization, high security.
- Outdoor PIR detectors — IP65 weatherproof, anti-vandal housing, temperature -40°C to +70°C, pet-immune, ideal for yards, parking lots.
- Wireless 433MHz/868MHz detectors — battery powered (1-3 year life), wireless connection to panel, easy installation, no cables needed.
FAQ — Frequently Asked Questions
Pet-immune (or pet-friendly) is function that allows PIR motion detector to ignore pets (dogs, cats) and not trigger false alarm. How it works: detector analyzes object size, weight, and movement speed. If object is small (<15kg or <25kg depending on model) and moves at low height (on floor), detector ignores it. If object is large (human) and moves vertically, detector triggers. This is necessary for homes with pets.
Wired detectors — connect to panel with cable, don't need batteries, more reliable connection, cheaper, but require cable installation (difficult installation). Wireless detectors — connect to panel with radio signal (433MHz/868MHz), battery powered (1-3 year life), easy installation (no cables needed), more expensive, but ideal for existing buildings where cable installation is difficult. Recommendation: wired — for new construction, wireless — for existing buildings.
Correct PIR detector placement is critical for effective protection. Recommendations: 1) height — 2-2.5m from floor (optimal viewing angle). 2) in corner — install in room corner to cover entire space. 3) at entrance — install facing door/window (entry path). 4) avoid — direct sunlight, heaters, air conditioners (false alarms). 5) testing — after installation test detector from different angles and ensure it covers entire space.
