Overview
The ZKTeco SenseFace 3A is an access-control terminal combining face, fingerprint, card and password authentication with a 2.8-inch touchscreen. Its 1 MP WDR binocular camera provides the facial capture hardware, and Linux is the documented operating system. The 3A includes an in-glass fingerprint sensor, providing an additional biometric route at the same terminal. The April 2024 datasheet documents 3,000 faces and 6,000 fingerprints for its standard configuration; the newer table introduces version distinctions. Facial authentication is specified at 30 centimetres to two metres, which helps define a deliberate approach to the terminal.
The listed user and card capacities are 6,000 each, with storage for 150,000 transactions. These limits describe different record types and should be assessed separately. TCP/IP provides wired networking, while the listed Wi-Fi option operates at 2.4 GHz. USB Type A is specified for a USB drive. Wiegand input or output and ZKTeco RS485 provide additional integration paths, alongside lock, sensor, exit-button and auxiliary connections.
The enclosure measures 166 × 63 × 25 mm. The power requirement is 12V DC, 3A. The IP65 rating describes the terminal enclosure; the installed wiring and connected door components still require suitable protection. Card-reader options, management software and door hardware need to be selected together. A supported connection or accessory does not establish its inclusion in the supplied package.
Applications & Use Cases
- Scheduled access for different staff groups: Configure the documented access levels, groups and holiday rules to distinguish when enrolled users may enter. The SenseFace 3A and its management configuration must be commissioned with the separately specified lock, exit arrangement and door wiring.
Product FAQs
What USB format is documented for transferring user data?
The April 2024 SenseFace 3A/3B datasheet specifies FAT32 for USB-drive user-data upload and download. Prepare the drive for that documented workflow; a USB connector does not establish direct PC peripheral operation or support for every filesystem.
Will SenseFace 3A read existing 13.56 MHz staff cards?
The standard reader is specified for 125 kHz ID cards; 13.56 MHz IC reading is an optional configuration. Match the fitted reader and credential technology before reusing a card fleet. Frequency alone does not prove compatibility with every card encoding or existing credential system.
Which indoor monitor connection should an intercom project specify?
The current table separates VT07-B01/B01-W on ZKTeco’s private TCP/IP protocol from VT07-B22L/B26L-W on standard SIP. Match the monitor model, protocol and firmware; “video intercom” alone does not establish interoperability. The older April 2024 leaflet groups B01 monitors under SIP, so that revision conflict must be resolved for the intended equipment.
Can access-control and attendance software use the same configuration unchanged?
The table names ZKBio CVAccess for AC PUSH and ZKBio Time for TA PUSH, plus ZKBio Zlink for cloud management. Firmware protocol switching is documented; it does not by itself prove simultaneous operation with multiple backends. Specify the intended software version, protocol and applicable licence.
Can a 14-digit employee number also be used as a 14-digit PIN?
No. The SenseFace 3A functions allow up to 14 digits for the user ID, but the maximum user password length is eight digits. Keep the employee identifier and authentication password as separate fields when mapping an existing staff database.
