Introduction

Does access control installation always give you a headache? Complex cabling, high labour costs, long construction periods… These pain points now have a simple yet powerful answer.

We are introducing our brand‑new 2-Wire Video Access Control System, putting “simplicity” at the very core. When you unbox it, you are not just looking at a device – you are experiencing a new way of security that is cost‑effective, hassle‑free, reliable, and scalable.

In this blog, we will unbox this 2‑wire solution and explain how it redefines the installation and use of access control systems.

1. 2-Wire Setup – Less Hassle, Lower Cost

Traditional access control systems (especially IP‑based ones) often require dedicated network cables (Cat5/6), PoE switches, or at least four‑core dedicated wires. This not only increases material costs but also demands more skilled labour and longer wiring time.

Our 2‑wire technology completely changes the game:

• Only two wires needed – Recommended ≥0.5mm² two‑core cable, transmission distance up to 100 metres.
• Non‑polarity connection – No need to distinguish positive and negative terminals; connect either way, eliminating rework.
• Power + signal over same two wires – Video, audio, unlock signals, and device power are all transmitted through the same pair of wires – no separate power cabling required.

Ventajas:

• Installation time reduced by more than 50% – Any general electrician or a confident DIYer can complete it quickly.
• Lower material costs – Two‑core cable is much cheaper than network cable or shielded multi‑core cable.
• Perfect for retrofit projects – Reuse existing two‑core wiring (old intercom lines, telephone wires) – upgrade to a modern video door phone without damaging decorations.

Para villas, self‑built houses, small apartments, offices, factories, the 2‑wire system significantly lowers the deployment threshold and overall cost.

3. Key Features – More Than Just a Doorbell

This 2‑wire system is not just a simple video doorbell – it is a smart security hub integrating access control, surveillance, alarms, and communication.

3.1 Premium IPS Screen – Clear and Comfortable Indoor Experience

The indoor monitor’s IPS technology ensures no colour shift or glare when viewed from the side. With 1024×600 (or higher) resolution, you can clearly see facial details, clothing, and even small objects the visitor is carrying. Touch‑button design makes it easy for children and the elderly to use.

3.2 IP65 Waterproof – Built for Harsh Outdoor Environments

Outdoor door stations are exposed to sun, rain, and dust. IP65 rating means:

• Complete dust‑tight – unaffected by sandstorms.
• Protected against low‑pressure water jets – heavy rain or a pressure washer will not damage the unit.
• Wide operating temperature – from -40°C to +70°C, stable in freezing northern winters and scorching southern summers.

The included rain cover further extends the device’s service life.

3.3 Motion Detection + CCTV Compatibility – Proactive Protection and Easy Expansion

• Human motion detection: The door station’s built‑in sensor can instantly send alerts to the indoor monitor and mobile app when someone approaches or lingers – you will know about unusual activity immediately.
• CCTV compatibility: The system supports connection of up to 20 ONVIF IP cameras (WiFi or wired), allowing you to view live feeds from your garden, garage, backyard, etc., all on the same indoor monitor or mobile app.

This means you don’t need a separate NVR or additional monitor – one indoor monitor becomes the central hub for your entire home surveillance.

3.4 Two‑Way Talk + Remote Unlock

• High‑definition two‑way audio: Echo cancellation and noise reduction ensure natural, clear conversations, even in noisy environments.
• Remote unlock: Through the Tuya / Smart Life mobile app, you can answer doorbell calls, view live video, and unlock the door with one tap – from anywhere. This is perfect for accepting deliveries, letting in housekeepers, or granting temporary access to visitors.

4. Why “Reliable, Scalable, Future‑Proof”?

Reliable

• Mature 2‑wire transmission technology – strong anti‑interference, no signal attenuation up to 100 metres.
• Industrial‑grade wide‑temperature components – suitable for extreme climates.
• IP65 protection + UV‑resistant housing – stable for years of outdoor use.

Escalable

• The system supports up to 2 outdoor stations + 4 indoor monitors in series (expandable with 2‑wire switches).
• Connect up to 20 ONVIF IP cameras – build a complete home security network.
• Multiple unlock methods available: RFID card, mobile NFC, optional face recognition.

Future‑Proof

• Admite Tuya app (optional) – future OTA firmware updates can add new functions.
• Certain models support SIP protocol for integration with third‑party PBX or property management systems.
• 2‑wire cabling is highly versatile – upgrading to newer indoor monitors or door stations in the future does not require rewiring.

5. Application Scenarios

Escenario	Why It Fits
Single villa	Two door stations (front + back) + multiple indoor monitors (living room + bedroom), plus IP cameras for garden surveillance
Townhouse / self‑built home	Use existing two‑core wiring to quickly upgrade to a video intercom – cost‑effective
Small apartment building	One door station at the entrance + indoor monitors in each unit – simple cabling, easy management
Office / retail shop	Reception indoor monitor + back door station + warehouse IP cameras – integrated management
Old community retrofit	No rewiring needed – reuse existing conduits and cables to achieve modern access control
