Z20 Smart Wireless Doorbell with 100° Wide-Angle Lens and Night Vision for Home Security

The Z20 smart wireless doorbell provides a practical video intercom solution for any home. It allows you to see, hear, and speak to visitors from anywhere using your smartphone, eliminating the need to open the door to unknown callers. The battery-powered design with low power consumption means minimal maintenance, while the 2.4GHz WiFi connection and cloud storage keep you informed even when you are away. This doorbell is a straightforward upgrade to home entry security without complex wiring.
Key Features and Construction

Built around an XR872 main controller with 32Mb of flash memory, the Z20 doorbell captures video through a 30W CMOS sensor and a 100° wide-angle lens. It records in 480P resolution at 7 frames per second, sufficient for clear identification of visitors during daytime or night.
Lens and Night Vision
The 100° wide-angle lens covers a broad field of view, reducing blind spots at your doorstep. For low-light conditions, two 850nm infrared LEDs provide night vision with excellent clarity at 1 metre and effective range up to 3 metres. The sensor also includes automatic white balance, gain control, and backlight compensation for consistent image quality.
Power and Standby Life
An 800mAh polymer battery powers the doorbell, with a deep sleep current of only 10mA. This enables a hibernation standby time of up to one year under typical conditions. When the battery requires charging, a standard DC 5V 1.5A USB charger can be used, and the working current is 219mA (280mA with infrared active).
Connectivity and Storage
The doorbell connects via 2.4GHz WiFi supporting 802.11b/g/n protocols and communicates using HTTP, TCP/IP, UDP, and P2P. It does not accept a TF card but offers cloud storage with three days of free cycle storage. When the doorbell button is pressed, it captures 5 images (key-triggered recording) and stores them securely online.
Uses and Placement

This wireless doorbell is suitable for residential use, especially where running power cables is impractical. Its compact size and simple mounting make it easy to install at any entrance.
Home Entry Monitoring
Mount the doorbell near your front door, gate, or side entrance. When a visitor presses the button, your phone receives an alert, and you can view a live preview (up to 3 users simultaneously) or initiate a two-way video call. The system supports one main account and up to eight sharing accounts, so family members can all stay informed.
Short-Term Event or Rental Use
Because the doorbell is battery-powered and wireless, it can be temporarily installed at rental properties, holiday homes, or events. The cloud storage and automatic gain control ensure reliable operation without onsite maintenance.
Benefits and Buying Value

The Z20 doorbell delivers a balance of essential security features and low ongoing costs. Its primary advantages are extended battery life, straightforward installation, and no monthly subscription fees for basic cloud storage.
Low Maintenance and Long Lifespan
The polymer battery's deep sleep capability means you only need to recharge every year or so, depending on usage. The absence of wired power and SD cards reduces the risk of failure, and the auto-exposure and white balance systems keep video usable in changing light.
Why Choose This Product
For anyone seeking an affordable, easy-to-fit video doorbell, the Z20 offers dependable performance with its wide-angle lens, night vision, and cloud storage. The ability to share access with up to eight users makes it practical for families, and the compact design ensures it suits most door frames.
