None that I am aware of but personally I would find this kind of method difficult to use. Trail cameras, Zoneminder and other programs tend to save each motion "event" into a separate file with the time and date in the filename. The idea is when you sort your list of video files alphabetically, the oldest video will be at the top and the newest at the end. Each video only contains a recording of the motion - if there is no motion, nothing is recorded. At this point you can play each video one by one by double-clicking on it, or add them all into a playlist in your preferred video player. By skipping to the next video file (usually one button press), you will jump directly to the next time the motion sensor triggered. It makes it very quick to skip through each video, and if you hit one you are interested in you can let it play through to watch it in full. The following video file will be the next event that happened afterwards, so it will be very similar to playing one long concatenated video, except each event is already in a separate file in case you need to send it to someone else or make a copy of it for future reference. > Or, even having one slider and being able to look at a time period after > that.

Normally these programs will only record video for a short time after the motion sensor has been triggered. So if you example you have a person enter the camera frame, have a sleep, then get up and leave two hours later, you'll only end up with two events lasting a minute or two each - first when the person enters the frame and again when they exit. Possibly another short video file or two if they roll over in their sleep. But the point is the cameras don't record continuously so you can't get 20 minutes after an event that only lasts for a few seconds. There are other ways to do this (recording continuously and flagging times when events happen) but this is a different problem and solution, and at that point there is nothing to concatenate because you have a continuous recording.

Re: [FFmpeg-user] FFMpeg question on Raspberry Pi
Thanks again for the information! Sorry for the late reply . . . for some reason, I only just got this . . . I would guess that there is a way to automate that concatenating via FFMpeg and I have a nephew that codes in Linux for a full-time job. I wanted to ask about the Raspberry Pi group what might be the best method(s) and then talk with him . . . We are most interested in being able to group videos by a certain time period, e.g., the motion tripped within a particular time period. The ideal setup would be looking at the concatenating video with two sliders - one for the beginning and one for the ending and downloading to the phone. While moving the sliders to see images/time stamps of the video where to start and stop. The time stamps could be on the original videos. Is the a video player that might be able to do that? Or, even having one slider and being able to look at a time period after that. For example, the 20 minutes of video following a certain identified point of the concatenating video . . .

Hi! Another tip, to use a USB mobile internet stick, and you can upload your video files to a Google drive cloud.

You're going to have to do a fair bit of programming/scripting to get this I suspect, as I don't think there's anything around that can do this out of the box on a Pi. However, since you won't want to use an SD card for this (as writing all the video will kill the SD card very quickly) you'll probably need to use a USB external hard drive. In this case you could just buy two, and swap them over when you visit the camera. Then back on another computer you can flick through the video on the USB hard drive. > 1.

They have motion sensors built in, they'll capture video of the motion, and save each event as a different video file. Then you can visit it, swap over the memory card, and watch all the videos on any device you can plug the card into (even a smartphone if you have a card reader for it). They run off batteries and include infrared lights to capture video at night, so they are well suited for remote areas where you don't need a live video feed. The only real benefit of using the Pi would be that you get Ethernet/WiFi on it for remote access/live video, but if you won't be using that because it's too far away from a WiFi network and you don't want to use WiFi extenders or dig a cable, using a game camera will probably save you a huge amount of effort.
