Hi, I am considering purchase of 2 or 3 Axis 207 cameras. I need to be able to view the images on a single web page and set a feature to record if triggered by motion detection at certain times (ie after 6pm). Please could you advise if I will require additional software of any kind and also what is the light level 0.5lux? I nderstand this is low but can you give me some idea of just how dark this is? Many thanks Dan.
