The FLIR A500-EST is a non-contact screening tool that can serve as a first line of defense against potential health risks. This FLIR EST™ thermal screening solution detects and visualizes heat to quickly identify individuals with an elevated skin temperature. With a 464 × 348 pixel thermal detector and on-camera FLIR Screen-EST™ Mode, the A500-EST can be deployed as a single, standalone screening station or in a network. Compatibility with industry standards such as Modbus TCP, MQTT, RESTful API for data transfer and RTSP for video makes third-party integration easy. The camera can be connected to most Video Management Systems and is compatible with FLIR Screen-EST™ Desktop software.


    Integrates easily into web services with RESTful API over XML or JSON; offers standard EtherNet and Wi-Fi connectivity.


    Optimal screening accuracy with automatic ambient drift compensation; support for external black body compensation if desired.


    On-camera FLIR Screen-EST Mode does not store images or personal information and allows for social distancing in screening setups.
