The IR-505M is a board level iris capture module rather than a finished camera. It is designed for product teams that already own the enclosure, the user interface and the application software, and simply need a reliable 5MP iris engine that can be screwed into an existing mechanical design. The whole imaging chain, sensor, lens mount, NIR illuminator driver and UVC bridge, fits on a 32 x 32mm four-layer PCB with four M2 mounting bosses and a single 5V input.
Because the module speaks standard UVC, it appears as a camera to Windows, Linux and Android hosts with no driver installation, which means an integration team can prototype in an afternoon and move to certification without rewriting their capture stack. Where deeper control is required, an optional SDK exposes exposure locking, illuminator timing, region of interest cropping and raw frame access, and a hardware trigger line lets the host fire a capture in exact sync with a card reader, a turnstile beam or an application prompt.
Key Features
- 32 x 32mm board footprint: four-layer PCB with M2 bosses and a 5V single rail input, sized to drop into kiosk bezels, ATM fascias and handheld enrolment devices that have no room for a cased camera.
- Interchangeable M12 lens options: 6mm, 8mm and 12mm focal lengths cover wide desk capture through to narrow long-range capture, so one board design serves several product variants without a redesign.
- Hardware illuminator sync: a dedicated strobe output drives an external 850nm LED ring in step with the sensor exposure window, keeping power draw and heat low in sealed enclosures.
- Trigger and GPIO control: an opto-isolated trigger input accepts a 3.3V to 24V pulse from a host controller, and status lines report capture-ready and illumination-active states to the main board.
- Low thermal load: typical consumption is 1.6W with illumination active and 0.9W idle, which keeps the module inside the thermal budget of fanless terminals.
- SDK and raw access: C library with Python binding supports frame grab, quality metrics, ROI cropping and template generation, while UVC mode remains available as a fallback for third-party software.
- Mechanical flexibility: a 150mm shielded FPC option moves the sensor head away from the main board, useful when the optical axis has to sit behind a tilted glass panel.

Applications
The module is intended for embedding rather than retail display. Common designs include self-service kiosks for telecom registration, ATM and cash recycler facial-iris identification, bank branch queue terminals, border and immigration pre-screening desks, hospital patient check-in stations, workplace attendance terminals that combine card and iris, and handheld enrolment units carried to remote villages. It also fits access controller projects where the iris camera must sit inside an existing vandal-resistant housing and report through the controller rather than a PC. Because the board is class compliant, the same hardware can ship in a Windows-based kiosk and an Android-based terminal with no firmware change, which shortens the certification cycle for teams building a product family.
Packaging and Quality Assurance
Modules are packed in ESD trays of 20 pieces, sealed in moisture barrier bags with a desiccant, and shipped 100 pieces per carton at approximately 6kg gross weight. Each board passes a 24 hour power cycle test, an illuminator strobe endurance run of 200000 cycles, and a lens focus verification against a target chart before packing. Boards are CE and RoHS compliant. A 12 month warranty applies to the sensor and bridge controller. For OEM customers, firmware splash screen, UVC descriptor naming, trigger polarity, lens selection and FPC length can all be customised, and a development kit with a breakout board, LED ring and reference application source is available for evaluation.
