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 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.
