A video doorbell is a smart home device that allows users to see and speak with visitors at their front door through their smartphone, tablet, or computer. These devices help enhance home security and convenience, and their features vary based on the technology ecosystem they are designed for, such as Google, Amazon, or Arlo. While there are differences in performance and design among models, the key considerations usually revolve around compatibility, ease of installation, and the need for cloud subscriptions. The Arlo Essential Video Doorbell Wire-Free is tailored for the Arlo ecosystem and offers a wireless installation that requires only drilling two small holes. It promises up to six months of battery life and includes a loud alarm. The device uses a smartphone app for notifications and can detect motion even before someone rings the doorbell, which may lead to an overload of alerts in busy areas. A subscription to Arlo Secure is needed for full access to features and cloud storage. The video quality is high, with a wide-angle lens and HDR sensor that provide clear images in various lighting conditions. A wired version of the doorbell is also available with similar performance and price. The Ezviz EP8 Ultra stands out with a dual-camera system, one for face recognition and the other for monitoring the doorstep. It includes night vision using an integrated LED and offers local storage of up to 32 GB. The doorbell also features interactive characters on its front screen to engage with visitors. The Ring Video Doorbell 4 maintains a simple yet effective design with Wi-Fi ac connectivity. It provides good video quality with a 180-degree field of view and can identify packages, vehicles, and pre-recorded faces. It works well with the Amazon ecosystem and Alexa. Ring offers three subscription plans, with the most expensive one enabling continuous recording on compatible devices. The Ring Video Doorbell 4 is priced at 199 euros. The Nest Doorbell, now available second-hand, integrates with the Google Home ecosystem. It features a more vertical video format but has a slightly lower video quality compared to newer models. A Google Home Premium subscription provides 30 days of video event history but does not support 24/7 recording. Its battery life is limited to about a month on a single charge. The Eufy Doorbell has been excluded from recommendations due to security concerns raised by consultant Paul Moore, who discovered a vulnerability that could allow remote access to data and recordings. When selecting a video doorbell, users should consider factors such as installation complexity, Wi-Fi range, video quality, field of view, audio features, and compatibility with other smart devices. Some models offer optional chimes for in-home alerts, and Wi-Fi repeaters can help extend signal coverage. Video quality ranges from Full HD to 4K, and night vision is crucial for security. Some doorbells can be connected to smart locks for remote access control. A sufficient internet bandwidth is essential, and cloud storage is usually necessary for full functionality. Additionally, doorbells should be at least IPX4 rated to withstand outdoor conditions.
