From image quality, talk performance to durability – a complete look at the new FARHD outdoor station
In any video intercom system, the outdoor station (door station) plays the most critical role as the “first line of defense”. FARHD’s new upgraded 4-wire video doorbell outdoor station brings breakthroughs in multiple technical areas. This article explains its core advantages.
Advantage 1: 4-Wire Transmission – Stable and Reliable
While 2-wire systems are simpler to wire, they may suffer from signal attenuation over long distances or in complex electromagnetic environments. FARHD uses a mature 4-wire technology where two cores carry audio and unlock signals, and two separate cores supply power – effectively avoiding crosstalk. It supports transmission distances up to 100 meters, suitable for villa gardens or long townhouse corridors. The system is compatible with mainstream 4-wire indoor monitors and electric locks, making upgrades or retrofits easy without rewiring.
Advantage 2: 1080P HD + Infrared Night Vision – Clear 24/7
The outdoor station features a 2MP (1080P) HD camera with a 115° wide-angle lens, capturing a full view of the area in front of your door. Built-in infrared night vision compensation automatically activates in complete darkness, providing clear black‑and‑white night video. Additionally, the camera supports WDR (wide dynamic range) and backlight compensation, ensuring the visitor’s face remains identifiable even under strong midday sun or evening backlight.
Advantage 3: Aluminum Alloy Body + IP65 Protection – Withstands All Seasons
Unlike ordinary ABS plastic, the aluminum alloy housing offers superior impact resistance et des weather resistance. After salt spray and UV aging tests, even in coastal or high‑UV areas, it will not fade, powder, or deform. IP65 rating means it is completely dust‑tight and protected against low‑pressure water jets from any direction – heavy rain or even a pressure washer will not affect normal operation.
Added Value: Two-Way Talk and Remote Unlock
Through the indoor monitor or Tuya/Smart Life app, users can perform remote video intercom and one‑key unlock. When a delivery person or visitor presses the call button, you can see a live video on your phone, talk to them, and after confirming their identity, unlock the door remotely. This feature is especially useful for frequent travelers, package recipients, or homes with elderly family members.
Dual-Color Design – Technology with Aesthetics
The silver and black aluminum finishes turn a technical product into an architectural accent. Whether your wall is modern white or red brick, you can find the perfect match.
Summary
Avec stable 4-wire transmission, HD night vision, durable aluminum body, and smart remote features, the FARHD upgraded 4-wire video doorbell outdoor station redefines quality standards for entry‑level video intercoms. If you are looking for a long‑lasting, high‑image‑quality outdoor doorbell for your villa or home, this new product deserves your attention
