What to Consider When Choosing a Security Camera?
When choosing a security camera, megapixels, night vision distance, and price alone are not sufficient. Camera resolution, lens and field of view, DORI/PPM analysis, WDR, low-light performance, recording capacity, artificial intelligence features, and cybersecurity must be evaluated together. We examine the technical criteria for selecting the right CCTV and IP camera.
How to Detect Hidden Cameras?
How to detect hidden cameras at home, in a hotel, or a rental apartment? We examine the operating principles, advantages, and technical limitations of lens inspection with phone light, infrared camera detection, Wi-Fi network scanning, and professional RF detectors. We explain what to do and your legal rights if a suspicious camera is found.
What Are Smart Lock Systems? How Do They Work and How to Choose Them?
What are smart lock systems, how do they work, and what features should be considered? We compare fingerprint, password, card, and phone-based door opening methods; Bluetooth, Wi-Fi, and Matter connectivity; door compatibility, security criteria, and emergency features. We examine the right smart lock choice for homes, offices, hotels, and businesses.
What is DORI Analysis in Camera Systems? How is it Performed?
DORI analysis is a technical method used to evaluate the level of detail at which security cameras can capture people or objects at specific distances. We examine the Detection, Observation, Recognition, and Identification levels, PPM calculation, lens selection, and the new criteria introduced with the IEC 62676-4:2025 standard.
Visitor Identity Security in Critical Infrastructures: Document Verification and Biometric Integration
HID's ATOM document scanner and U.ARE.U face verification module are integrated on the Soloinsight CloudGate platform with CTS kiosk hardware, creating a self-service architecture that automates identity verification in critical facilities.
