Recommend camera for viewing pets 24/7

I need a set of cameras that I can use to watch my animals while I'm gone and record them 24/7. One of these will be for my female kenyan sand boa who is expecting young soon, so I need a camera with good night recording for her. Another is for my female panther chameleon who I am expecting to lay eggs soon, for this I need basically the same camera. For both of these I would also like to be able to view it from my phone at any time. Motion detection is not needed. In addition to these two which would be set in a specific direction 24/7, I would like a third that I can place in my aquarium room that does not have to record, but I need to be able to control and view it from my phone. I would like all 3 to be ceiling mounted.

Pretty much any modern camera can do all these things. Really the only tricky/expensive feature you want is a digital pan/tilt/zoom camera.
