The Best Smart Video Intercoms of 2026 for Houses and Apartments

For a house, a 2-wire system is the most reliable if a cable already runs between the gate and the front door; an IP intercom adds full control from your phone. Two-wire kits send video, audio and power over the existing doorbell cable without relying on Wi-Fi. IP intercoms need a solid network connection at the gate, ideally a PoE cable or an outdoor Wi-Fi bridge on a long driveway. Many hybrid kits pair a wired indoor screen with call forwarding to an app.

Usually yes, as long as the new indoor unit is compatible with the building's system; the entry panel at the street door belongs to the building owner or condo association. Note the make and model of your current handset, since many apartment buildings use systems from brands such as Aiphone or Comelit that only accept matching units. Alternatively, an adapter such as Ring Intercom or Nuki Opener connects to many existing handsets and sends calls to your phone. Check your lease before changing any wiring.

Yes, most video intercoms can trigger an electric strike or maglock and a motorized gate, as long as the voltages and contact types match. An electric strike typically needs 12 V, which the intercom's power supply must provide, while gate openers usually expect a dry contact. If you unlock remotely from the app, choose a strike that relocks automatically once the door shuts.

Usually not for the basics: calls to your phone and remote door opening are typically free, but cloud recording of visitors may cost extra. Check what works without a plan before you buy, especially visitor history and the number of users. Building intercoms that ring residents' cell phones over a 4G SIM, found in some apartment buildings, carry a monthly fee paid by the building owner or management company.

Most picture problems come from the wiring: corroded terminals at the outdoor panel, a cable run that's too long for the system or a weak power supply. Check the outdoor panel's terminals for moisture, and compare the cable length with the manufacturer's maximum for your wire gauge. For IP intercoms, check the network signal at the gate. Poor night images often improve with better lighting at the entrance and a clean camera window.
