Video Resolution and Field of View
Video resolution ranges from 1080p to 2K HDR across our analyzed products. Entry-level 1440p appears on the Roku doorbell ($49.99), while 2K dominates at 80% market share including Tapo D210 ($69.99), Arlo 2nd Gen ($49.99), eufy E340 ($149.99), and WYZE Duo ($107.67). The Google Nest 3rd Gen ($166.00) leads with 2K HDR for enhanced color accuracy. Field of view varies from 150° (Roku) to 180° (Arlo, REOLINK), with head-to-toe viewing becoming standard. The eufy E340 and WYZE Duo feature dual cameras eliminating the traditional tradeoff between wide coverage and detail clarity.
