I am currently using iSpy with a USB webcam for a simple setup watching my office and it seems to work pretty well. I notice that iSpy is getting a constant image and recording whenever it detects motion. I'm planning to expand my system with 4-5 new cameras and I have a question about motion detection. A lot of cameras seem to offer motion detection as a feature. Is this done in the camera? How I would like it to work is: The camera detects motion, and only sends video when there is motion. This way my computer isn't burdened with constant image processing for motion detection, and my wifi spectrum isn't polluted with 4-5 1080P video streams 24/7--I imagine the cameras should only transmit video when they detect motion. Is this a possible setup with iSpy? Or if not, is there a better way to accomplish this? I really like iSpy's interface and I especially like working from a computer rather than a proprietary NVR. Thanks!
