I just buy and install a pack of 2 ref 932L, purchased in promo here. - Delivery fast as usual with amaz. - Given the info to find the SHIFT and then config without problems. - The image quality on Mac (in day mode color) is correct if the brightness of the room is good, the night mode is NB, which seems normal, lack of light. - The setting options can improve the picture (640x480) - The sound is correct. Which fail (or not found) is being able to return sound to the camera from the MAC to diloguer with the person in the room. In final; rapp good price / quality. Telephone contact pre-sales and after-sales: no problem. number on the website D.Link
