Example of data file storage window.

Each image or video taken by a camera is converted to a digital file and sent to the computer running the control software where it is stored as a .jpg or .mp4 file in a sub-directory on the computer’s hard drive.  From there, it may be e-mailed to a list of recipients by the host PC.  Some users develop their own simple programs to display the images on the cloud or big screens as they come in.

The actual size of still image files largely depends on the resolution setting of the camera.  But the complexity of the image itself can have a significant effect too.  A 5 Mp image of a bunch of snow may be the same size as a 1 Mp image with texture.  In general, images taken at the lowest resolution (1/3 Megapixel or 640×480 or VGA) are adequate and are less than 50 Kb in size.  Images can also be taken at 1, 2, and 3 Mp in standard or HD aspect ratio.  The highest resolution is 5 Mp at standard aspect ratio.  These images can be about 1 Mb in size.

Video files arrive as an .mp4 file  and are about 500 Kb per 10 seconds of video in size.  Frame rate is adjusted automatically by the camera as needed to conserve file size and can be as high as 15 frames per second.  So a video file of a pack of turtles would likely be smaller in size than a video file of a group of hogs taken a minute later by the same camera at the same settings.

We have obtained download speeds with X80’s even faster than the manufacturer’s claim of 5 Kb/sec.  X7D’s seem to max out at about 2.5 Kb/sec.  Download speed is proportional to signal strength and can get pretty slow, tenths of Kb/sec, with a very weak signal.

Conclusion:  Modern PC’s should have no trouble with the data storage needs.  In almost all applications, transmission speed will be the limiting factor for users’ image resolution and video time settings.  One thousand VGA images would take up less than 50 Mb of hard drive storage.
