Find motion events in videos
View all tagsSecurity camera motion detection turns a change in a scene into a useful event. Depending on the system, that event can start recording, send a notification, switch on a light, or trigger an alarm.
The difficult part is not detecting any change—it is deciding which changes matter. This guide explains the main detection methods, why false alerts happen, and how to configure a camera so its recordings and notifications remain useful.
MoFind 1.1.5 makes full-screen motion event previews easier to close with an improved drag gesture. The update also supports reduced motion for a calmer preview experience.
These changes continue a series of focused improvements to MoFind, an app for finding motion events in long surveillance and monitoring videos on iPhone, iPad, and Mac.
MoFind is built for long-video review. It is designed for long, mostly static recordings such as security-camera, doorbell, and trail-cam footage, so you can avoid manually scrubbing frame by frame.
MoFind scans videos on-device offline and turns motion moments into a browsable event list with start time, duration, motion score, and thumbnails.
