I use mine plugged in for power, and with a SD Card (Samsung 64Gb Class 10 U3). This camera does a great job! Motion detection works pretty well.Pros:1) Great Image, under natural light or IR illumination.2) And the IR is truly "Black IR"!3) Ball mount with magnetic base works AOK.4) Wide angle lens is good - everything is in focus corner to corner. Very Nice!I do have a few problems/suggestions though, Cons:1) It would be nice to be able to download the video files from the camera via a shared drive type of option - in either direction. Meaning: Let me access the device storage (with password, of course) from a computer and download the files like any other shared device drive. That way I don't have to use the HIDVCAM app and download them painfully 1 at a time to my phone and then move them to my computer. Or, let me set access to a shared drive on my computer and let the camera push the video files there in the background (NOT while recording the file).2) Sound is recorded with the only option being "Chinese - 1 Channel" instead of something more compatible (or something I can set) such as "Windows Media Audio V8 - 2 channel", and none of my available playback methods allow me to hear this default channel (maybe I just need a more flexible player?).3) Motion detection is pretty spot on, but it would still be nice to set "Hot" (only look here) and/or "Cold" (never look here) areas and a Threshold value.4) Ideally, I'd like to set the "Lead-In" timing on motion detection videos - meaning that I'd like the option to capture a couple of seconds prior to when the motion trigger clicked. Obviously that would require the camera to buffer the video until it was needed, but it would be a nice feature!
