IP66 Fingerprint & RFID Access Control Reader | Asia-Teco SF4
Asia-Teco SF4 — IP66 Waterproof Fingerprint & RFID Door Access Control Reader
Secure your entry points with the Asia-Teco SF4, a heavy-duty, all-in-one access control reader built for both indoor and outdoor use. Housed in an anti-vandal zinc-alloy metal case and rated IP66 weatherproof, this integrated unit combines a capacitive fingerprint sensor with a 125KHz RFID proximity card reader — giving you flexible, multi-mode authentication in a single sleek device.
Why Choose the SF4?
- 1,000-User Capacity: Supports up to 100 fingerprint users, 890 RFID card users, and 10 visitor users all in one system.
- IP66 Weatherproof Rating: Completely dust-tight and protected against powerful water jets — ideal for gates, exterior doors, and covered entry points.
- Fast Fingerprint Identification: Capacitive fingerprint module with 500 DPI resolution identifies users in under 1 second, with an ultra-low false acceptance rate (FAR <0.001%).
- Anti-Vandal Metal Construction: Durable zinc-alloy body resists tampering and physical damage.
- Multi-Color LED Status Display: Instantly communicates access granted, denied, or system alerts at a glance.
- Integrated Alarm & Buzzer Output: Built-in alarm deters unauthorized access attempts.
- Adjustable Relay Output: Configurable lock release time from 0–99 seconds (5-second default), supporting NO, NC, and Common configurations with up to 2A load.
- Wide Operating Range: Functions reliably from -30°C to 60°C (-22°F to 140°F) and in humidity from 10%RH to 99%RH.
- Low Idle Current: Draws less than 45mA at idle, keeping energy consumption minimal.

Frequently Asked Questions
Q: Is the Asia-Teco SF4 RFID fingerprint reader suitable for outdoor installation?
A: Yes. The SF4 carries an IP66 weatherproof rating, meaning it is fully protected against dust ingress and powerful water jets. It operates reliably in temperatures from -30°C to 60°C and humidity up to 99%RH, making it well-suited for exterior gates, covered entryways, and outdoor access points.
Q: What types of credentials does the SF4 access control reader support?
A: The SF4 supports three credential types simultaneously: capacitive fingerprint (up to 100 users), 125KHz EM RFID proximity cards (up to 890 users), and visitor codes (up to 10 users), for a combined total of 1,000 users.
Q: What locks is this reader compatible with, and how do I wire it?
A: The SF4 includes one programmable relay output (NO, NC, Common) with an adjustable lock release time of 0–99 seconds and a maximum load of 2A, making it compatible with most electric strikes, magnetic locks, and electric bolt locks. Wiring connections include relay output, exit button, alarm, and door contact terminals.
Q: How quickly does the fingerprint sensor identify a user?
A: The capacitive fingerprint module identifies enrolled users in under 1 second with a false acceptance rate of less than 0.001%, ensuring fast, highly accurate entry for authorized individuals.
