Building Security — What to Know Before Buying
Modern property security is not just an alarm on the wall — it is a layered system combining physical barriers, electronic surveillance, and biometric access control. The key difference between amateur and professional systems: professional systems operate completely autonomously, without relying on internet or remote servers.
Biometric Access Control
- Fingerprint readers — optical and capacitive sensors, response time under 0.5s, 99.9% accuracy. Recommended: ZKTeco, Suprema, Anviz.
- Face recognition — infrared cameras work in the dark and cannot be fooled by photos. Works fully offline with local face database.
- Smart locks with biometrics — Yale, Assa Abloy, dormakaba — fit standard cylinders, battery-powered 12–18 months, fully offline.
Cloud-Free Video Surveillance
- IP cameras — 4–8 Mpx resolution, night vision, AI motion detection (person/vehicle classification).
- Local NVR — records to local HDD, no internet required. 2TB HDD = 30 days of continuous recording on 4 cameras.
Alarm Systems
- Professional panels: DSC, Paradox, Texecom — standalone operation, GSM/SMS notification without internet.
- Backup battery: 24–72h operation during power outage.
Fire Protection
- Smoke, heat, and CO detectors — EN 54 certified, fully autonomous.
- Addressable systems — Bosch, Siemens, Hochiki — pinpoint accuracy.
