Why Choose This Tuya 2-Wired Non-Polarity Video Intercom?
2-Wired Non-Polarity Bus Wiring & Expandable Configuration
The system adopts a 2-wired non-polarity bus connection between the outdoor door station and indoor monitor. Installers can reuse existing two-core wall wiring for renovation projects. Flexible expandable options allow you to add multiple indoor monitors with master-secondary ID setting. The system also supports connecting up to 2 outdoor door stations to one main indoor monitor for multi-entrance villa scenarios. This makes it suitable for 2 wire video intercom, 2 wire intercom retrofit, legacy wiring intercom upgrade, and non polarized 2 wire intercom projects.
7-Inch Full Touch-Screen Indoor Monitor & Multi-Language Menu
The indoor monitor features a 7-inch full capacitive touch screen with an intuitive graphic UI. It has a built-in multi-language customizable OSD menu and supports date-time standby display. You can directly complete unlock, parameter setting, TF-card formatting, and recorded file playback on the touch screen. Screen brightness and ringtone volume are adjustable for daily usage. This makes it a practical indoor video intercom screen for villa video intercom and home security intercom.
PIR Motion Detection & Max 512GB TF-Card Local Recording
The smart PIR human motion detection function sends an instant push alert to the bound Tuya App when human movement is detected near the door entrance. Insert a TF-card to trigger auto snapshot and loop-video recording, saving visitor call logs and motion-triggered footage locally. The system supports a maximum 512GB TF-card. You can play back photos and videos directly on the touch screen. No mandatory cloud subscription is needed for local storage. TF-card is sold separately. This supports motion detection doorbell, PIR motion sensor doorbell, and local recording video intercom searches.
Tuya Smart Life App Remote Control
Download and install the Tuya Smart or Smart Life App. It is a large platform that can add multiple categories of smart products. Compared with a shared account, all family members who add this device have more unlocking functions. Up to 20 administrators and family members can be added to a single family. The video intercom is a device with a high security level. The device must be removed from the original account before it can be bound to a new account. This supports Tuya app remote intercom, remote door unlock system, and smart building entry system applications.
IP65 Outdoor Door Station, 1080P 110° Wide-Angle & IR Night Vision
The IP65 waterproof and dust-proof outdoor door station is fit for all-weather outdoor installation. It has a built-in 2MP 1080P HD camera with a 110-degree wide viewing angle. The IR-Cut infrared night vision automatically switches day-night mode to deliver a clear image under dark environments. It has an integrated physical password keypad on the panel. The relay output supports external electric lock and magnetic lock. Independent power supply is highly recommended for the external lock to avoid hardware damage caused by wrong wiring. This makes it a durable outdoor video intercom station for villa video intercom and 2 wire bus video intercom.
4-in-1 Unlock Modes & Two-Way Audio-Video Intercom
- Password Unlock: Enter the correct access password directly on the outdoor keypad.
- RFID IC-Card Unlock: Swipe an IC-card on the outdoor panel for quick family access.
- Touch-Screen Unlock: Tap the unlock icon on the 7-inch indoor full touch screen.
- Tuya & Smart Life App Remote Unlock: Real-time remote unlock and live-view monitoring on iOS and Android mobile phones.
When a visitor presses the doorbell button, all paired indoor monitors and bound mobile phones ring simultaneously. Real-time hands-free two-way audio-video conversation is supported between the indoor monitor and outdoor door station. This supports keyless door entry system, RFID access control system, and smart building entry system.

Q: I purchased two screens, how do I install them?
✅ A: Set the screen connected to the doorbell as the main screen (Digital ID: 1). Connect the next screen using the OUT port, connect the second screen to the IN port, and change the Digital ID to 2.
Q: How do I add my fingerprint and password?
✅ A: Please refer to this tutorial video: How to add fingerprint and password
Q: Does the video intercom device support connecting to sliding doors?
✅ A: Yes. Use the doorbell "COM" and "NO" two wires to connect to the sliding gate opener.
🔍 Troubleshooting
Q: The doorbell keeps ringing
✅ A: If the outdoor station does not have a card swipe function, set it to "don't support access card" mode. If it supports card swiping, set it to "support card" mode.
Q: The device works but the doorbell does not ring when pressed
✅ A: Set the screen to Home Screen Mode. If it is set to Message Mode, it will not ring.
Q: Image is blurry, black and white, or no image
✅ A: Set the settings to PAL 1080 and automatic. You can also adjust it on the back of the doorbell. Watch tutorial
Q: Device suddenly cannot connect to the Internet
✅ A: Power off and restart the device, or update the system.
Q: No voice from the doorbell (audio issue)
✅ A: Check the line settings to see if the audio cable is dropped, has poor contact, or has fallen off. You can also plug it into door2.
Q: Lock connected to doorbell won't open the door
✅ A: Check the wiring. If it doesn't unlock when connected to the 2PIN port, connect to the 3PIN port to power the lock. Also pay attention to distinguish between NO and NC.
Q: LED indicator on the screen does not light up
✅ A: If you bought 64218 or 64202, there is a separate 2PIN line. You cannot use the doorbell's 2PIN line because the positive and negative poles are opposite. The correct connection is the red line close to the LED indicator. If it still doesn't light up, it may be a motherboard issue.

1.3 Refund Amount
- Refund = product purchase price (excluding original shipping fees).
- Free Return service (where offered) applies only if the product is in new, resalable condition.
- If an inspection reveals that the damage was caused by you (including incorrect wiring) rather than a product defect, we will deduct the repair costs or refuse the refund.
1.4 EU 14-Day Right of Withdrawal
If you are a consumer in the EU, you have a 14-day cooling-off period to withdraw from the purchase without giving any reason. The right of withdrawal ends 14 days after you (or a person you designate) take physical possession of the goods. You must bear the direct cost of returning the goods, unless we offered free return. This statutory right is not affected by our 30-day guarantee, but the product must not show damage from misuse or improper installation.
🔧 Section 2 – Limited Warranty (18 Months)
We warrant that the product is free from defects in materials and workmanship under normal, intended home use for the following periods from the original purchase date:
| Use Type | Warranty Period |

| Commercial / business use | 12 months |

🇪🇺 Section 4 – Special Provisions for the European Union (EU)
4.1 Legal Conformity Warranty (2 Years)
You have a 2-year legal guarantee that the goods conform to the contract at the time of delivery. However, you must prove that the lack of conformity existed at the time of delivery. If the product is damaged after delivery due to incorrect installation, that is not a lack of conformity at delivery.
4.2 14-Day Right of Withdrawal
You have 14 days to cancel the purchase. You lose this right if you have installed, mounted, or modified the product beyond what is necessary to inspect it. Simply opening the package is fine; drilling holes, connecting wires, or attaching the doorbell to a wall constitutes "using" the product and may limit your withdrawal rights.
🇺🇸 Section 5 – Special Provisions for the United States (US)
For consumers in the US, this warranty is a limited warranty and is governed by the Magnuson-Moss Warranty Act and applicable state laws.
5.1 Implied Warranties
Any implied warranties (e.g., merchantability, fitness for a particular purpose) are limited to the duration of this express warranty (18 months). Some states do not allow limitations on how long an implied warranty lasts, so this may not apply to you.
5.2 Limitation of Consequential Damages
We are not responsible for any incidental or consequential damages (such as loss of time, inconvenience, damage to your home wiring, door, or other property). Some states do not allow the exclusion of consequential damages, so this may not apply to you.
5.4 Installation Warning – US Emphasis
⚠️ In the US, improper installation is the #1 cause of doorbell failures. We strongly recommend installation by a licensed electrician. If you connect any electric lock or accessory without a separate power supply, you assume all risk of damage. This limited warranty does not cover such damage.
📋 Section 6 – General Provisions (All Customers)
6.1 How to Contact Us
Email: sales@anjielo.com
WhatsApp: +8617336198736
Please include your order number and photos/videos of the issue when possible.
6.2 Governing Law & Dispute Resolution
For EU customers: Your mandatory consumer rights are governed by the law of your country of residence.
For US customers: This warranty is governed by the laws of the state of the seller's registered address. Any dispute shall first be attempted to be resolved through binding arbitration upon either party's request.
6.3 Changes to This Policy
We may update this policy from time to time. The version applicable to your purchase is the one in effect on the date of your order.
