Good, I would like to buy a couple of cameras for my business. I don't want much, I don't have much budget either. I do not want a security system where you store everything, I want a couple of simple cameras that are put on the wall and recorded by Wifi. The problem is that I don't know how to look for them or I don't know exactly what they are called, and I don't know if I can or not. For that reason, what I ask for is a link to Amazon or a store to ask for, thanks. The features I look for in the camera are the following: - Minimum HD recording. - Night vision. - That it can be controlled from home (I don't know if possible, what I want is to be able to see it via the Web or like that from home) - If possible, in addition to recording it to a micro SD, I would like to know if it is possible to record it to a server (in case they stole the camera, if they take the card, it is saved on some type of external server) I think what I ask is complicated, but if you have that recording to an external server, I would be willing to pay a little more. A greeting and thanks in advance!
