Why Choose This 7-Inch 4-Wire Video Intercom System?
7-Inch Touch-Button Indoor Monitor

Functions include 2-way intercom, monitoring, unlocking, and mute mode. Power supply is DC 15V 1.2A. The monitor size is 205mm × 108mm × 22mm. This makes it a practical indoor video intercom screen for apartment video intercom, multi apartment video intercom, and building intercom system projects.
1.0MP Outdoor Camera with Motion Detection
The outdoor video intercom station uses a 1.0MP 1/4-inch CMOS camera sensor with a 3.6mm lens and 90-degree viewing angle. It supports motion detection for visitor awareness. The camera is built with an aluminium alloy body and flush-mounted installation. It is powered by the indoor monitor. The outdoor unit size is 275mm × 125mm × 45mm. This motion detection doorbell feature supports smart building entry system and multi-tenant video door entry applications.
10M Night Vision with Automatic Brightness Detection
The outdoor camera is equipped with a night vision function that identifies the brightness of the surrounding environment. In the dark, the video doorbell automatically turns on night vision so you can see a clear image of your surroundings. You can clearly see the appearance of visitors, making it easier to identify them. This night vision video doorbell supports outdoor video intercom station, apartment video intercom, and commercial building intercom projects.
Hands-Free Two-Way Audio and Auto Close
When a visitor presses the bell, the monitor activates and displays the external environment. Press the answer button to speak outside, and press the answer button again to close. If you cannot answer the call or complete a dialog, the monitor automatically closes after 60 seconds. This hands-free video intercom and two-way audio doorbell function improves daily security and visitor management for apartment buildings, villas, and gated communities.
IP65 Waterproof and Weather-Resistant Outdoor Doorbell
The outdoor doorbell is made of aluminium alloy material. It can easily resist rain, snow, and bad weather. The installation package includes a 5m cable for easy connection between the doorbell and monitor. It can be used by connecting the power supply. The outdoor camera has an IP65 waterproof rating and works in operating temperatures from -30°C to 60°C. This IP65 waterproof video doorphone is suitable for outdoor gate, building entrance, and courtyard wall mounting.
Electric Lock Support and Easy Installation
The system works with an electronic lock. A power controller is needed to control the electric lock. The installation package includes tools for easy setup. The indoor monitor supports surface mount, and the outdoor camera supports flush-mounted installation. This one-key unlock function brings convenience for apartments, villas, and multi-family buildings. The electric lock is not included unless selected separately.

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.
Q: Device shows no permission to add device

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 |

🇪🇺 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.
