Overview
The ZKTeco SFace900 is a multi-biometric time-attendance and access-control terminal with face and fingerprint identification. Its 4.3-inch touchscreen provides the local interface. The manufacturer’s Hong Kong datasheet describes a semi-outdoor installation under eaves and a maximum illumination of 12,000 lux. That is a defined, sheltered installation context rather than evidence that the terminal can be exposed to unrestricted weather.
The dated datasheet documents TCP/IP, RS232/485 and USB host communication, with connections for an electric lock, door sensor, exit button and alarm. These support an attendance point or a separately designed door installation. The control interfaces do not establish that the lock or other door components are supplied. Local functions include automatic status switching, self-service queries, work codes, short messages and daylight-saving adjustment, supporting the organisation of recorded clocking activity.
Manufacturer and supplier figures differ: the available 2016 datasheet and this supplier record cannot be treated as one verified capacity specification. The exact hardware and regional revision must be established before selecting an enrolment limit or fitted communication option. ZKTeco lists operating conditions of 0–45°C and 20–80% humidity in that document. Assess those conditions at the proposed mounting point, and identify the required host software, credentials and power arrangement for the actual unit being quoted.
Applications & Use Cases
- Scheduled attendance prompts: The documented scheduled-bell function can support configured clocking routines at the attendance point. Define the relevant times and event-collection workflow; a scheduled prompt does not itself calculate employee hours.
Product FAQs
Which face and fingerprint limits are established for this supplied unit?
The 2016 Hong Kong datasheet lists 1,200 faces and 2,000 fingerprints, while the supplier record lists 3,000 faces and 4,000 fingerprints. The exact supplied revision has not been matched to either specification. Obtain its model label and applicable manufacturer datasheet before sizing enrolment against the larger figures.
Does the optional battery guarantee four hours of operation?
The dated datasheet describes an optional 2,000mAh battery and approximately four hours of operation. That is a manufacturer reference for its documented configuration, not a runtime guarantee for an unspecified supplied battery. Confirm that battery option and its condition if power continuity is essential.
Is the supplier’s 4G option confirmed by the linked datasheet?
No. The 2016 document lists optional Wi-Fi, 3G and ADMS, while the supplier record mentions 4G. A fitted 4G modem requires exact configuration evidence; the earlier optional 3G reference does not establish it.
Which attendance software is shown in the manufacturer’s system diagram?
The 2016 diagram names ZKTime.Net 3.0. That establishes the historical documented arrangement, not universal support for current cloud platforms or every software release. Identify the deployed software and firmware before integrating or replacing a terminal.
Can the Wiegand connection be assumed to accept an external reader?
The dated datasheet specifies Wiegand signal output. An output is not evidence of a Wiegand reader input. Check the exact host and output format when using the terminal in another access system; the presence of RS485 also does not prove support for every external reader.
