Single Camera to commission. I use it to "watch" My mother is old and whose health is shaky. Most: Opportunity to keep in memory positions. Ability to view images on a Smartphone (Galaxy S2 for me). Good image quality Night vision (infrared) Input and output its ability. Possibility to upgrade the firmware. Cons: I regret that there is no Zoom. On this model, bottlenecks have appeared (remains fixed in one position). I have not had this problem with the black model. Just reboot the camera.
