DS-K1T671MF and DS-K1T341AMF support the same core access methods but suit different deployment scales. DS-K1T671MF provides a 7-inch screen, a 0.3–3 m face-recognition range, and larger face, card, and fingerprint capacities. DS-K1T341AMF uses a compact 4.3-inch screen, a 0.3–1.5 m range, and 3,000-user-class capacities. Both are IP65-rated face access terminals.
Model comparison
| Specification | DS-K1T671MF | DS-K1T341AMF |
|---|---|---|
| Product position | Pro face access terminal | Value-series face access terminal |
| Display | 7-inch LCD capacitive touch screen | 4.3-inch LCD capacitive touch screen |
| Camera | 2 MP wide-angle lens | 2 MP wide-angle lens |
| Face-recognition distance | 0.3–3 m without a face mask | 0.3–1.5 m |
| Specified face-recognition duration | Less than 0.2 seconds per user | Less than 0.2 seconds per user |
| Face capacity | Up to 6,000 | Up to 3,000 |
| Card capacity | Up to 6,000 | Up to 3,000 |
| Fingerprint capacity | Up to 5,000 | Up to 3,000 |
| Card type | Built-in M1 card reader | Built-in M1 card reader |
| Environmental protection | IP65 | IP65 |
| Best-fit deployment | Higher-volume entrances and longer approach range | Smaller entrances and cost-controlled deployments |
The published face-recognition accuracy is at least 99% under defined conditions. Real performance depends on enrollment quality, face angle, lighting, camera height, distance, occlusion, firmware, and threshold settings. Validate the actual entrance before volume deployment.
DS-K1T671MF: larger screen, range, and capacity
DS-K1T671MF is the larger terminal. Its 7-inch interface is easier to view at a busy entrance and its specified face-recognition distance extends from 0.3 m to 3 m without a face mask. That wider approach range can support entrances where users should be recognized before reaching the door.
Capacity is also higher: up to 6,000 faces, 6,000 cards, and 5,000 fingerprints. These limits matter for multi-department sites, facilities with frequent credential changes, and projects that need several authentication methods. Capacity alone does not define system size; controller topology, door count, event storage, network architecture, and management software remain separate design items.
The terminal supports two-way audio with compatible clients or stations, TCP/IP, web configuration, ISAPI, and ISUP 5.0. Confirm which functions are enabled by the regional firmware and the management platform used by the project.

DS-K1T341AMF: compact value-series terminal
DS-K1T341AMF uses a 4.3-inch touch screen and supports up to 3,000 faces, 3,000 cards, and 3,000 fingerprints. Its face-recognition distance is specified from 0.3 m to 1.5 m. This makes it suitable for controlled approach points where users stand closer to the reader.
The terminal supports TCP/IP, ISAPI, ISUP 5.0, web configuration, two-way audio with compatible system components, and an M1 card reader. IP65 protection supports appropriate indoor or sheltered outdoor installation, but cable entries, back box, weather exposure, temperature, condensation, and mounting remain installation-level considerations.

Mask-alert functions
Both product pages list mask-related alert modes. Depending on configuration, the terminal can provide a voice reminder and either allow or fail authentication when the configured mask rule is not met. This is a policy feature, not a default requirement. Verify current firmware behavior and whether the project still needs the function.
How to choose between the two
Choose DS-K1T671MF when
- the entrance needs a larger user interface;
- users should be recognized over a longer approach distance;
- the project needs more than 3,000 face or card records;
- a higher-volume site justifies the larger terminal.
Choose DS-K1T341AMF when
- the entrance has a controlled, short approach path;
- 3,000 faces, cards, and fingerprints cover planned growth;
- a smaller screen and enclosure are preferred;
- the project prioritizes a compact value-series design.
Deployment checklist
- Confirm user count, growth, cards, fingerprints, and face-template requirements.
- Map the terminal to the door controller, lock, exit device, alarm input, and power supply.
- Verify mounting height, approach distance, backlight, face angle, and accessibility.
- Check network segmentation, time synchronization, user roles, logs, and backup.
- Confirm firmware, region, management software, and mobile or intercom integration.
- Define enrollment, credential revocation, data retention, and administrator ownership.
- Test normal access, failed access, offline operation, power recovery, and emergency release.
Before enabling biometric templates, the responsible project owner should confirm the site’s applicable privacy, notice, retention, access-control, and security requirements. A product feature list does not establish project compliance.
Frequently asked questions
Which terminal supports more users?
DS-K1T671MF. It supports up to 6,000 faces, 6,000 cards, and 5,000 fingerprints, compared with 3,000 of each on DS-K1T341AMF.
Which terminal has the longer recognition distance?
DS-K1T671MF, with a specified 0.3–3 m range without a face mask. DS-K1T341AMF is specified for 0.3–1.5 m.
Are both terminals weather resistant?
Both are listed as IP65. That rating does not replace correct sealing, cable entry, mounting, power protection, temperature control, or shelter where required.
Can both terminals use face, card, and fingerprint authentication?
Yes, both models support those credential types. Confirm the required authentication combinations, card format, fingerprints, management platform, and regional firmware.
