Tired of complicated wiring? Our two‑wire connection makes installation a breeze while delivering crystal‑clear video and two‑way talk.

If you have ever struggled with running new cables through finished walls or configuring network settings for a smart doorbell, you know that “simple” is not always the reality. That is why we designed our 7‑inch Indoor Monitor with two‑wire technology – the simplest, tidiest, and most hassle‑free way to add a high‑definition video intercom to your home or office.

Why Choose Our 7‑inch Indoor Monitor?

🔹 7‑inch HD Screen – See Every Detail Clearly

The large 7‑inch IPS display delivers sharp, vibrant images. Whether it is a delivery driver, a guest, or a family member, you will see their face, clothing, and even small packages with exceptional clarity. The wide viewing angle means you can check the screen from anywhere in the room without colour distortion.

🔹 Two‑Wire Tech – Simple, Tidy, and Hassle‑Free

Forget about separate power cables, network wires, or complex IP configurations. Our two‑wire non‑polarity technology transmits power, video, audio, and control signals over a single pair of standard wires (≥0.5mm, up to 100 metres). Connect either way – no need to worry about positive and negative terminals. This makes it perfect for:

• Retrofitting older buildings – reuse existing two‑core cabling (old intercom lines, telephone wires). No wall damage, no tenant disruption.
• New construction – run just one simple cable from the door to the indoor monitor. Less material, less labour.

🔹 Real‑Time Doorbell Response – Never Miss a Visitor

When someone presses the call button, the indoor monitor rings instantly and displays the live video feed. There is no delay, no buffering, and no “device offline” errors. You can answer immediately and see who is there.

🔹 Two‑Way Talk – Communicate Naturally

Built‑in high‑quality microphone and speaker deliver full‑duplex audio with echo cancellation. Talk to visitors as if they were standing next to you – no shouting, no confusion. Give delivery instructions, greet guests, or even deter unwanted solicitors – all without opening the door.

🔹 Sleek Design – Fits Perfectly in Any Room

The monitor features a modern, minimalist design with a glass lens and slim profile. It blends seamlessly into any interior – from a contemporary apartment to a classic villa. Wall‑mount it in your hallway, living room, or home office.

1. Run a single two‑core wire from the door station to the indoor monitor location (or reuse existing wiring).
2. Connect the wires – no polarity, so there is no wrong way.
3. Mount the indoor monitor on the wall bracket.
4. Power up – the included 15V adapter powers both the monitor and the door station.
