433MHz Wireless Wiegand Access Control Reader & Receiver

433MHz Rolling Code Wireless Access Control Wiegand Reader & Receiver System

Upgrade your home or business security with the Asia-Teco WK1 Wireless Access Control System — a reliable, easy-to-install solution featuring 433MHz rolling code technology, dual-frequency card support (13.56MHz & 125KHz), and seamless Wiegand integration. Whether you're securing a front door, gate, or office entry, this wireless reader and receiver combo delivers professional-grade access control without complicated wiring.

How Does the Wireless Reader System Work?

The system consists of two components: an outdoor wireless reader and an indoor receiver. The reader is mounted at the entry point, while the receiver can be placed anywhere indoors within a 30-meter range. The receiver then connects to your existing access control board via standard Wiegand wiring (26-bit or 36-bit programmable output), making it fully compatible with most access control panels on the market.

Frequently Asked Questions

Q: Is the 433MHz Wireless Wiegand Reader compatible with my existing access control panel?

A: Yes — the Asia-Teco WK1 supports programmable Wiegand output in both 26-bit and 36-bit formats, which are the two most common standards used by access control boards worldwide. Simply connect the receiver's Wiegand wires to your controller as you would with any standard card reader.

Q: Can the wireless reader be used outdoors in wet conditions?

A: Absolutely. The reader unit carries an IP65 waterproof rating, meaning it is fully protected against dust ingress and water jets from any direction, making it suitable for outdoor installation on gates, exterior walls, and entry points exposed to rain.

Q: How long do the batteries last in the wireless reader?

A: The reader is powered by 3x AAA batteries and is designed for energy-efficient operation. Under typical usage of approximately 30 card/key reads per day, the batteries will last around 6 months before needing replacement.

Q: What is rolling code technology and why does it matter for access control security?

A: Rolling code (also called hopping code) technology generates a new unique code with every authentication event. This means that even if someone intercepts the 433MHz transmission, they cannot reuse the captured code to gain access — significantly improving the security of the system compared to fixed-code readers.
