Team Digit | Published on 09 Mar 2021 BelBird Technologies uses a combination of thermal, motion, radar sensors and mobile device attributes to provide the protective features of more conventional surveillance systems, such as intruder detection and checking for authorised access in both office and home environments. The system can be configured to allow for particular movement of people during certain timings, increase or decrease security levels, and can be installed much existing surveillance setups. The surveillance system is non intrusive, and works without cameras, but can potentially be integrated with biometric identification and other technologies in the future. We spoke to BelBird Technologies to find out more about their surveillance system that bypasses the use of cameras.
