Turn a spare iPhone or iPad into a private home security camera. PerchCam gives you local live view, event recording, and smart alerts without forcing your video through a cloud account. OLD PHONE AS CAMERA Use an unused iPhone or iPad as a live camera for your home, baby room, pets, shop, garage, or office. Place it where you need a view, plug it in for long sessions, and keep monitoring. LOCAL LIVE VIEW Watch from another PerchCam device, a browser, or compatible local players. PerchCam monitor devices can provide web, HLS, and RTSP outputs on your local network, so you can use another phone, a computer browser, VLC, an NVR, Home Assistant, or compatible tools in your own setup. SMART DETECTION Get notified when something important happens: - Motion detection - Person detection - Baby cry detection - Alarm and unusual sound detection - Pet and animal activity - Camera obstruction and scene changes Events can be saved locally with snapshots and video clips, so you can review what happened without scrolling through hours of footage.

USEFUL FOR - Home security - Baby monitoring - Pet watching - Elder care check-ins - Small shop monitoring - Garage, driveway, and entryway checks - Reusing an old iPhone or iPad - Local browser, HLS, and RTSP playback PRO FEATURES Upgrade to unlock the full monitoring workflow, including live streaming features, smart detection, extended event history, email alerts, webhook alerts, and advanced monitoring options.

Verdict
The clearest difference is in-app purchases: NVS Viewer at none against PerchCam's 2. NVS Viewer also leads on iOS requirement (12.0 vs 17.0). PerchCam's advantage is update cadence (every 2 weeks vs every 60 months). On price, ads and device support there is nothing between them.
