Introduction

This 2-wire video door phone lets you see and speak to visitors at your door from a 7" colour touchscreen indoors, or remotely on a smartphone or tablet through the TUYA Smart app. The weatherproof outdoor unit has a 1080p FHD camera with infrared night vision for clear colour images in any light, and connects to the indoor unit using just two cores of cable. From the indoor screen you can monitor the camera, hold a two-way conversation with your visitor, and release both an electric door lock and an electric gate.

Mounting

Indoor unit

Fasten the fixing bracket for the indoor unit to the wall using the fixing kit provided. Use the screws and wall plugs if fixing straight onto the wall surface, or the fixing bolts if you are using a back-box. If using wall plugs and screws, drill two horizontally level 6 mm holes about 63 mm apart.

Outdoor unit

1. Install the outdoor unit at a height of 1.4 m to 1.7 m from the ground, out of direct sunlight and away from constant exposure to moisture.
2. Fasten the rain guard bracket in the chosen location using the screws and wall plugs provided, drilling two vertically aligned 6 mm holes about 82 mm apart.
3. Run a length of 2-core cable between the indoor and outdoor units, securing it away from doors and walkways where it could be damaged.
4. Connect the wires as described under Connections.
5. Clip the unit into the rain guard bracket and secure it underneath with the small screw provided.

Connections

Use good-quality 2-core cable, choosing the diameter to suit the length of the run:

Cable run	Minimum core size
Up to 15 m	0.2 mm²
Up to 30 m	0.5 mm²
Up to 50 m	1.0 mm²
Up to 100 m	1.5 mm²

For an electric door lock or gate release, use 2-core 1.0 mm² cable up to a maximum distance of 5 m.

1. Connect terminals 1 and 2 on both units as shown in the diagram above (these two cores are not polarity-sensitive).
2. Terminals 3 and 4 on the indoor unit are for an electric door lock. Pressing the door release applies 12 V DC at up to 3 A.
3. Terminals 5 and 6 on the indoor unit are voltage-free closing contacts rated at 2 A for an electric gate release. The gate release must have its own 24 V power supply; the contacts act as a switch when wired in series.
4. Connect the power supply to the indoor unit and hang it on its fixing bracket.
