The S4A Tuya Dynamic Facial Access Control with TCP/IP has several notable features and advantages,
as follows:
1. High Recognition Accuracy: It adopts a dynamic face detection and tracking recognition algorithm based on video streams. It supports a local device storage of 10,000 face libraries. When the face database contains 3,000 faces, the recognition accuracy of 1:n is 99.7% under the condition of a 3/10,000 error rate.
2. Fast Identification Speed: Face tracking and detection take about 20ms, face feature extraction takes about 200ms, and face comparison time is 0.2ms for a 1,000 - people database (multiple recognition averaged) and 0.5ms for a 10,000-person database (multiple recognition averaged). Such speed enables quick passage for authorized personnel, improving access efficiency.
3. Diverse Unlocking Methods: In addition to dynamic facial recognition, it also supports fingerprint, password, card-swiping, remote control, and optional mobile phone app remote opening. This offers users multiple options, allowing them to choose the most convenient unlocking method according to different scenarios.
4. Good Environmental Adaptability: Many models have an IP66-compliant waterproof design, which can work normally in outdoor environments with water exposure and dust, and can adapt to a wide range of temperatures from - 30℃ to 60℃. The metal housing also has anti-vandal properties, making it suitable for various public places and harsh environments.
5. Powerful Communication Capabilities: It supports TCP/IP communication, enabling easy connection to a local area network or the Internet. This allows for centralized management and remote control of access control systems, facilitating monitoring and management by security personnel. It also supports HTTP interface docking, which is convenient for integrating with other systems.
6. Other Features: It supports functions such as saving on-site photos during face recognition or stranger detection, as well as stranger identification and comparison. Some models also support human body temperature detection under indoor conditions, enhancing the functionality and practicality of the device.
