It drops into an existing peephole, puts a 4.3-inch touchscreen on the inside and records 1080p to a microSD card of up to 512 GB. The Eufy Video Doorbell E340 counters with dual cameras, 2K video, color night vision, package and familiar-face alerts plus automatic replies, and it stores clips on 8 GB of built-in storage or a Eufy HomeBase. Both skip HomeKit and Matter. Choose the EZVIZ CP4 for a no-drill apartment door and a proper indoor screen; choose the Eufy Video Doorbell E340 when packages on the stoop and 2K dual-lens coverage matter more than the peephole form.
