Why Choose This Anjielo 2-Wire Non-Polarity Video Intercom?
2-Wire Non-Polarity BUS Wiring for Easy Installation
The system uses a non-polarity 2-wire-bus wired connection between the outdoor door station and indoor monitors. Installers do not need to distinguish positive and negative wire polarity, which greatly simplifies installation and old-building renovation wiring work.

Up to 4 Independent Families / Apartments
This system is optimized for up to 4 independent families or apartments. Each apartment can have an independent call button on the outdoor door station.

It is suitable for small multi-apartment buildings, townhouses, multi-unit rental properties, and old-house renovation projects. This supports multi apartment video intercom, multi unit intercom system, and multi tenant video door entry.
Two-Way Audio-Video Intercom & Room-to-Room Inter-Call
When a visitor presses the corresponding apartment call button, the matched indoor monitor will ring. Residents can have real-time hands-free two-way audio-video conversation between the outdoor station and the indoor monitor.

This supports hands free video intercom, two way audio doorbell, and video door entry system applications.

The outdoor station has a fish-eye wide-angle camera sensor, metallic frame body, IP65 waterproof performance, customizable color, adjustable door open time and volume, and card unlock function. The relay output supports external electric lock and magnetic lock for access control. An independent power supply is highly recommended for the external lock to avoid hardware damage caused by wrong wiring. This supports outdoor video intercom station, IP65 waterproof video doorphone, and keyless door entry system.
Tuya Smart Life Remote Access Function
Connect the master indoor monitor to a 2.4GHz WiFi network to unlock Tuya Smart Life App features, including remote live-view monitoring, remote door unlock, and visitor snapshot alerts on mobile phones. It supports real-time remote management for multi-apartment property managers and residents. The indoor monitor only supports 2.4GHz WiFi; 5GHz WiFi is not compatible.

Indoor Monitor as Admin Monitor & Do Not Disturb Function
The indoor monitor supports intercom, unlock, and real-time monitoring with the outdoor unit. It has a do not disturb function for deep night. The indoor monitor can be used as an Admin monitor to broadcast to residents. Admin setting password is 888888. This supports residential intercom solutions and smart building entry system applications.
Expandable with 2-Wired Switch Board & Up to 2 Locks
A 2 Wired Switch Board is required if connecting more than three devices. The door station can connect up to 2 locks. If using one lock, priority connect in gate 1 port, and the lock can get power from the door station. If connecting a second lock in the lock-PWR port, the lock should connect an extra adapter. For magnetic lock, switch to “M”; for electronic lock, switch to “E”. This supports electric lock and magnetic lock for option.
Support 2 IP Cameras (Dahua & Hikvision)
The system supports 2pcs IP cameras connected at the same time. IP camera types include Dahua and Hikvision brand IP cameras. The IP camera connects to the router.

Installation & Wiring
Non-Polarity 2-Wire BUS Connection
The outdoor door station and indoor monitor adopt a non-polarity 2-wire-bus wired connection. Installers do not need to distinguish positive and negative wire polarity.

Long-Distance Installation
Recommended 2-core bus cable, CAT5, or CAT6. When wiring distance exceeds 30 meters, please adopt a separate power supply for the outdoor door station. This ensures stable video transmission and reliable system performance for high rise building intercom, building intercom network, and apartment intercom replacement projects.
Master / Secondary Monitor ID Setting
If connecting one monitor, device ID select “1”. If connecting two monitors, slave monitor device ID select “2”. This allows multi-room and multi-apartment configurations.
2-Wired Switch Board
A 2 Wired Switch Board is required if connecting more than three devices. This allows the system to expand for multi-unit intercom system and multi apartment video intercom projects.

Q: I purchased two screens, how do I install them?

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).

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:

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.
