Can a Canon EOS 550D shoot one frame per second via an IR remote for time-lapse?

I’m triggering a Canon EOS 550D / Rebel T2i with an IR LED for time-lapse. At 6-second intervals it works reliably, but when I try to trigger it every 1 second the timing becomes inconsistent. I’ve disabled automatic settings and reduced image size, which helped a little, but I still see bursts of shots followed by several seconds with no response. Is 1 frame per second too fast for this camera when using an IR remote, or is something else likely limiting it?

It should not be but you would have trouble if long shutter noise-reduction kicks in. On some cameras it can be disabled entirely.
From your description, it sounds like it could be a slow card. You lowered the resolution which should help but I have no idea how slow your card is. Try a faster card.

1 shot per second should generally be possible on a 550D, so the interval itself is not necessarily too fast. Based on the answers, the likely limits are:
- Long-exposure noise reduction: if this is enabled, the camera may spend extra time processing after each shot, which can disrupt regular intervals. Disable it if possible.
- Memory card write speed / buffer clearing: your burst-then-pause behavior strongly suggests the camera is filling its buffer and then waiting to write images to the card. A faster card may improve consistency.
Reducing image size can help, but it won’t fully solve things if the card is the bottleneck. Also make sure your shutter speed and any in-camera processing aren’t adding delay.
So, 1 fps is not inherently too high, but consistent 1-second triggering depends on camera processing settings and how quickly images can be written to the card.
