Are You in the Market for a Doorbell Camera? Consider These Key Factors! When shopping for a doorbell camera, it's essential to consider the type of power source, aspect ratio, and installation requirements. Some doorbells run on batteries, while others require existing wiring. Battery-powered cameras may have limited recording capabilities during power outages. Wired doorbells, on the other hand, provide more reliable video capture. Aspect ratios like 4:3, 16:9, or 1:1 can impact the type of view you get. A square view (1:1) is ideal for most users, but wider aspect ratios may be better suited for larger porches. Installation requirements vary between battery-powered and wired doorbells. Battery-powered cameras are generally easier to install, while wired doorbells require more effort or professional installation. Source: https://www.theverge.com/22954554/best-video-doorbell-camera
