Door Entry & Intercoms
Video doorbells and intercoms let you see and speak to whoever's at the door, from the porch or your phone. Check power (battery vs wired/transformer), whether it needs a subscription for recorded clips, field of view, and compatibility with existing chimes or smart-home hubs. For apartments, confirm the intercom matches your building's wiring before buying.
