Face Recognition and Temperature Detection Access Control Technology
Control access to buildings, offices, factories, plants, and other facilities by verifying persons identities with a 99% face recognition accuracy. Does not grant access to anyone with a high fever or without a mask. 2M’s terminal software can determine if the person passing by is wearing a mask or not. It can also read his/her temperature and determine, based on a configurable pre-defined temperature threshold, if access should be granted or not.
Module Features:
- Fast recognition time within 0.2 seconds. Various models merge mode are used to reduce false rate and increase pass rate
- Non-contact temperature detection, abnormal body temperature warning system
- Body temperature detection and personnel information binding, which can quickly confirm personnel information while scanning body temperature
- Configurable temperature detection threshold value
- Temperature range between 30˚C to 45˚C
- Accuracy between 0.1˚C to ≤0.3˚C, distance is up to 1m
- Learning algorithm maximizes accuracy rate >99% and reduces the false rate <1%
- Dedicated learning chip supports local offline recognition up to a 10,000 face capacity, face whitelist (1:N)
- WDR, 2MP (1080P) low illumination wide-angle camera and F1.6 large aperture lens for capturing high quality image with various complex lighting scenes
- Anti-spoofing detection based on deep learning algorithm, effective against fraud such as presenting a photo or video rather than a live person

Choosing Between the 2MTT-8, 2MTT-8A, and 2MTT-8A-BLM
All three models share the same tripod turnstile mechanism and face recognition/thermal detection module — the difference is how the arm drops and how much daily traffic the unit is built to handle. The base 2MTT-8 uses a semi-automatic, hand-pushed arm rated for up to 500 passes per day, with a 2-3 year expected lifetime and a 3-million-cycle MTBF (mean time between failures) — a fit for lower-traffic entrances like a small office lobby. The 2MTT-8A steps up to a motor-driven arm rated for 1,000 passes per day, a 3-5 year lifetime, and 5-million-cycle MTBF, with quieter operation and fewer moving parts subject to wear. The 2MTT-8A-BLM uses a brushless motor rated for 2,000 passes per day, at least 5 years of service life, and a 10-million-cycle MTBF — built for high-traffic facilities like factory shift changes or multi-tenant office buildings where the turnstile cycles constantly throughout the day.
As a rule of thumb: choose the 2MTT-8 for light foot traffic where budget is the priority, the 2MTT-8A for moderate daily traffic where quieter, more reliable operation matters, and the 2MTT-8A-BLM for high-cycle environments where minimizing maintenance and downtime outweighs the higher upfront cost.
Installation and Power Requirements
The 2MTT-8 series runs on standard AC100V~240V input with a DC 24V driving voltage, so it fits into most commercial electrical setups without specialized power infrastructure. The open signal input accepts a 12V relay or 12V dry contact, making it compatible with most third-party access control panels and card readers already in use at a facility.
A critical safety feature built into every model in this line: the turnstile arm automatically drops and unlocks when power is cut. This fail-safe behavior aligns with the NFPA 101 Life Safety Code, which requires electronically controlled egress hardware — including turnstiles and gates in assembly occupancies — to unlock automatically on power loss so occupants are never trapped behind a powered barrier during an outage or fire alarm activation. Any facility installing access-controlled turnstiles should confirm this fail-safe behavior is part of their local fire marshal's sign-off before final inspection.
Frequently Asked Questions
What's the difference between the 2MTT-8, 2MTT-8A, and 2MTT-8A-BLM?
The core difference is the drive mechanism and duty cycle. The 2MTT-8 is semi-automatic and hand-pushed, rated for up to 500 passes/day. The 2MTT-8A adds a motor-driven arm rated for 1,000 passes/day. The 2MTT-8A-BLM uses a brushless motor rated for 2,000 passes/day and the longest service life of the three. See the comparison table above for the full spec breakdown.
What happens to the turnstile arm if the power goes out?
The arm automatically drops and unlocks, allowing free passage. This fail-safe design is standard across all three models and aligns with NFPA 101 Life Safety Code requirements for electronically controlled egress hardware.
How accurate is the face recognition on the 2MTT-8?
The learning algorithm is rated for greater than 99% accuracy with a false rate below 1%, and supports local offline recognition for up to 10,000 faces on the dedicated learning chip, with anti-spoofing detection to guard against someone using a photo or video instead of appearing in person.
Can the 2MTT-8 integrate with an existing access control system?
Yes. It accepts a 12V relay or 12V dry contact open-signal input, and supports two-side card readers, paper tickets, fingerprint readers, and coin mechanisms, so it can typically integrate with card-based or biometric access systems already in place at a facility.
Does the thermal detection feature require a mask to work?
No. The system can determine whether someone is wearing a mask and independently reads body temperature, checking it against a configurable threshold (30˚C to 45˚C range, accuracy between 0.1˚C and 0.3˚C) to decide whether to grant access — mask detection and temperature screening operate as separate checks.
How many people can pass through per minute?
Up to 35 people per minute at a pass width of 550mm or less, with recognition completing in as little as 0.2 seconds per person.
