The FingerTec R3c provides an exceptional security upgrade for modern business premises requiring tight entry and exit surveillance. This compact slave unit connects directly to your existing core architecture to handle secure biometric dual-direction door setups. First, the terminal features an advanced, non-coated optical scanner to read fingerprints smoothly from any angle. Therefore, it passes encrypted authentication data back to the primary unit to grant building access in under one second. Furthermore, its rugged Acrylonitrile Butadiene Styrene (ABS) shell carries an official IP65 weather-resistance certification. For instance, it can withstand extreme dust, sand, or outdoor rain storms perfectly without degrading hardware lifespan. Additionally, this minimalist reader terminal offers great administrative flexibility and easy physical installation. It utilizes a space-saving narrow casing that fits onto slim door frames or clean vertical wall mounts flawlessly. For connection mobility, the unit links to master readers like the FingerTec R3 or Q2i via a standard RS485 communication line. After that, the system automatically pipes exit swipes into your Ingress desktop management software to calculate employee shift changes and track real-time anti-passback violations. Meanwhile, all electronic lock control outputs and emergency alarm configurations are safely managed away from the physical door by the indoor master controller. As a result, this weather-resistant slave system cuts down daily technical support issues while keeping your corporate workplace highly secure.
