So, the new 5MP brings Reolink to a new level of image quality. I was quite happy with the images from my 411WS with its 4-megapixel sensor (2560 x 1440), but wow - the 5-megapixel sensor opens you up to 3072 x 1728 resolution, and that is a significant step up. Bigger is better, right? Well, yes - but the roughly 30% increase in resolution means a fair amount of additional data can be streaming through your network, and if you have an older or inadequate network, then the extra data load may slow you down a bit. Add a few 5MP cameras to your system and you may soon be in the market for a nice network upgrade.
