Product Analysis and System Design
Outdoor Video Intercom Station with PIR Sensor
The outdoor video intercom station is built with PIR human motion detection and IR LED night vision lights. It supports visitor activity detection near the building entrance and provides clear 960P images day and night. The outdoor station connects to compatible electric lock and magnetic lock for building access management. This makes it a reliable outdoor video intercom station for apartment video intercom and commercial building intercom.
Indoor Video Intercom Monitor for Each Household
Each paired indoor monitor allows residents to communicate with visitors and unlock the door directly from the indoor unit. The system supports additional indoor monitors after initial installation. Please set a unique digital ID for each indoor monitor following daisy-chain wiring rules in the user manual. This supports multi apartment video intercom, apartment intercom replacement, and residential intercom solutions.
Wiring and Installation
4-Core Cable / CAT5 / CAT6 Wiring Support
For multi-household installation, use qualified 4-core cable. CAT5 or CAT6 cable is also acceptable. This 4-wire video intercom system uses a 4-wire connection for stable building communication. It supports 4 wire analog video intercom, building intercom network, and high-rise building intercom projects.
Long-Distance Wiring and Independent Power Supply
For long wiring distance over 30 meters, a separate power supply for the outdoor door station is suggested. Long cable can cause signal attenuation. Use high-quality thick-gauge 4-core cable. If the distance exceeds 30 meters, please apply an independent power supply for the outdoor door station to maintain clear video transmission.
Legacy 4-Core Cable Reuse for Renovation
This 4-wire intercom can work with legacy 4-core building cables for renovation projects. Please check cable continuity and insulation condition before installation. This makes it suitable for apartment intercom replacement and legacy wiring intercom upgrade in older buildings.

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.

📑 Table of Contents / Navigation

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 |
|---|---|
| Normal household use | 18 months |
| Commercial / business use | 12 months |
2.1 What IS Covered
- Hardware failures due to manufacturing defects.
- Functional defects in pre-installed software.

2.4 Resolution Options for Valid Claims

📦 Section 3 – Free Return Service (Where Offered)

🇪🇺 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.
