I am looking for a cheap solution to setting up a temporary security camera for night time surveillance of an area. I have an old PC it can be hooked to, and I will just stick the camera out an upstairs window. It do want to make sure it has reasonable software with it, so it will activate from motion, and it would benefit from being at least 1080p. At the moment I have a hi res logitech webcam camera doing this, and it came with basic motion activated software, so it works well during the day. However during the night it doesn't work, even when using an infrared light source on the area, and it is at night when it is needed. It only needs to capture an area about 10 metres in size, but it need not be all that wide angled. Anyone have any suggestions? I don't want o invest much in it as it is only going to be temporary
