✦ Ultra-slim 44mm body, compatible with narrow door frames for all scenarios
Featuring a rarely-seen ultra-narrow 44mm profile in the industry, this terminal is tailor-made for compact door frames. Ideal for glass-door offices, light luxury office buildings, entrance doors of high-end residential compounds, and old community renovation projects. It fits perfectly even with minimal mounting space reserved on door frames without looking obtrusive or taking extra space, balancing practicality and aesthetic appearance.

✦ Premium All-Metal Precision Chassis with Brand-New Aesthetic Design
The F339 undergoes a complete redesign covering color schemes, exterior molds and internal hardware circuits:
▫️Integrated solid aluminum alloy casing, wear-resistant and scratch-proof. It retains its original color and shape without deformation even after years of continuous commercial deployment.
▫️2.5D curved tempered glass touch panel with silky smooth surface, fingerprint-resistant and impact-resistant.
▫️Custom backlit logo available. Minimalist streamlined design complements the interior styles of all high-end commercial offices and residential buildings.
▫️Dual 2MP anti-backlight cameras equipped with infrared sensors and smart fill lights, supporting instant fast facial recognition under harsh lighting conditions including strong backlight, bright sunlight and dim night environments.

✦ Multiple unlocking methods & all-scenario access permission management
Comes standard with multiple verification modes, and a QR code module is available as an option: Facial Recognition | IC Card Swipe | Touch Password | Bluetooth Remote Unlock.
It supports professional access control schedule permission management, temporary visitor authorization, elevator control linkage and parking lot linkage, making centralized management much easier for office building and residential property teams. The device supports offline local operation, so normal access will not be interrupted even when disconnected from the network, with Ethernet port as standard configuration.

✦ Industry-leading tech: PLC two-wire long-distance transmission, ideal for old building renovation projects
The F339 Pro exclusively adopts a split POE/PLC long-distance communication solution, its core competitive advantage for retrofitting old premises. Conventional Ethernet requires 8-core network cables, which drives up construction costs and creates huge threading difficulties in the walls of old residential compounds. The PLC communication of F339 Pro only needs two wires to transmit Ethernet data up to 1 kilometer. Paired with the matching split PLC receiving module, it transmits network signals and power through existing old wires, eliminating the need for new slotting and network cable laying!
▫️ Optional POE power supply module delivers power and data transmission via a single cable, greatly simplifying on-site wiring
▫️ Compatible with the classic RS485 remote communication protocol, matching most legacy access control renovation systems
▫️ Split modular design enables flexible on-site installation, drastically cutting construction man-hours and material costs for renovation projects
