Frame rate

Reviewers note that the C660 records at 15fps by default with an option to increase to 20fps for smoother clips, and that in its 24 7 mode it runs at a very low 1fps background stream that ramps back up when motion is detected, a trade-off that is acceptable for security footage but less fluid than typical smartphone-style video.

Owners note that the S3 Pro is capped at around 15 frames per second; earlier tests felt this could blur fast motion, but more recent reviews report that footage generally looks smooth and watchable even when people are moving quickly.

As with several Eufy models, the E340 is limited to about 15 fps, and this review again calls out that fast-moving people or cars can appear a bit blurry because of the lower frame rate.

Multiple reviewers criticize the S340’s 15-fps limit, and this article again reports that the low frame rate leads to noticeable blur and choppiness when people or cars move quickly through the frame.

Feedback consistently notes that the camera’s frame rate is limited, with continuous mode running at very low fps and motion events capped at 15 fps, making motion look less fluid than on 25–30 fps models even though static detail is strong.

Multiple tests criticize the Argus 4 Pro’s 15-fps frame rate, and this review reiterates that fast-moving subjects can look choppy or blurred even though overall image clarity remains high.
