Overview
Alarm.com built this video doorbell to work inside its own security service: a hardwired camera with HDR video, people detection and two-way audio. It runs off existing doorbell wiring and needs an Alarm.com interactive plan with video.
Tight integration with an Alarm.com security system is the case for it, with dual-band Wi-Fi for a steady link. Without a service plan it does nothing useful. Specs on the listing conflict on night vision range and viewing angle.
Who it's for
Households whose alarm provider runs on Alarm.com and who want the doorbell in the same app suit it. Renters or buyers with no service contract should choose a consumer doorbell instead.
Pros and cons
- People detection cuts false alerts
- Full-duplex two-way audio
- Dual-band Wi-Fi with MIMO
- Weather resistant for outdoor use
- Requires an Alarm.com service plan
- Spec table conflicts with the bullets
- Needs existing doorbell wiring
Performance notes
Video stability depends on the Wi-Fi signal at the door, which the dual-band radio and two antennas help hold. HDR balances bright sky and shaded porches. Infrared range limits how far it sees after dark.
