Who it fits

Key specs explained for this model

Video Resolution: 2K FHD

This resolution provides higher pixel density than standard 1080p HD. You will see clearer details on faces and clothing. The extra clarity helps identify visitors from a distance. It is useful if you need to verify who is at the door. Compare this with 1080p models to see if the improved detail justifies the choice for your security needs.

Storage Type: 8GB eMMC local storage

The device stores footage directly on the hardware without requiring a cloud account. You do not need a monthly subscription to save videos. This setup protects your privacy by keeping data on your premises. It is ideal for users who want to avoid recurring fees. Check the capacity against other models to ensure it holds enough video for your typical usage patterns.

Night Vision: Color night vision

This feature captures nighttime footage in full color rather than black and white. It uses a dual-light system to illuminate the area. You can see the color of clothing and vehicles clearly in low light. The effective range extends up to 16 feet. This is distinct from infrared night vision found in many competitors. It helps in identifying details that monochrome cameras miss.

Power Source: Rechargeable battery or wired (16–24V)

You can choose between a swappable rechargeable battery or a hardwired connection. The battery option allows for flexible installation without existing doorbell wires. The wired option supports 16–24V sources for continuous power. This dual capability suits both new installations and retrofits. Compare this flexibility with battery-only or wire-only models to find the best fit for your home's electrical setup.

This dual-power approach lets you choose the setup that fits your home structure.
