Overview
The ZKTeco SenseFace 4B is an access-control terminal combining face, card and password authentication with a 4.3-inch touchscreen. Its 1 MP WDR binocular camera provides the facial capture hardware, and Linux is the documented operating system. The 4B omits the fingerprint sensor fitted to the 4A. Facial authentication is documented, but the current manufacturer table leaves its face-template capacity unresolved; the 4A capacity must not be substituted. 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 8,000 each, with storage for 200,000 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 175 × 84.5 × 21.65 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 4B and its management configuration must be commissioned with the separately specified lock, exit arrangement and door wiring.
Product FAQs
Can the 8,000-user figure be used as the face capacity?
No. User records and face templates are different limits. The current manufacturer table marks the 4B face-capacity cell with a slash despite listing face authentication. An exact 4B datasheet or manufacturer clarification is needed before a numerical face limit can be confirmed.
Will SenseFace 4B 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.
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 4B 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.
