For example, you can set the machine to record on timeframes you’re away from the house, and not record if you’re home. This will drastically cut down the video storage required. 3 Play with the resolution, frame rate, and bitrate until you achieve a picture quality that you’re happy with. The lower they are, the less video storage required. However, don’t go too low. Try to find the perfect balance. 4 Exclude objects that unnecessarily trigger motion detection.
