The Reolink D340P Wired PoE Smart Video Doorbell offers superior reliability, faster data speeds, and easier installs vs. traditional hardwired and Wi-Fi doorbell cameras. Know who’s at your door every time – even when you’re away from home! Home doorbell lets you greet guests and watch package deliveries - day and night - with head-to-toe video and infrared night vision. Razor-sharp 2K+ (5MP) resolution gives you twice the clarity of standard 1080p wired doorbells. Person and Vehicle detection algorithms greatly reduce false alerts. Plug the included chime into a normal electrical outlet anywhere inside your home. Synch the smart doorbell to your Reolink smartphone app. Connect to a Reolink NVR or Home Hub (sold separately) or record directly to an onboard microSD card (up to 256GB, sold separately).
