The ZKTeco FR1200 is a rugged fingerprint reader designed for reliable access control in both indoor and outdoor environments. It uses a small-size ZK optical fingerprint sensor paired with the ZKFinger VX10.0 algorithm, enabling precise fingerprint capture and transmission via RS-485 communication. The standard version includes a 125 kHz ID card module, while there is an optional upgrade to support 13.56 MHz MF cards. The unit features a buzzer for audio feedback, along with LED indicators to show verification success or failure. Built with durability in mind, the FR1200 has an IP65 rating, meaning it’s protected against dust and low-pressure water jets—suitable for outdoor installation. It operates on 12V DC power, functions between 0-45 °C temperature range, has dimensions of roughly 102 × 50 × 37 mm, and is compact enough for wall- or mullion-mounting.
