So I knew setting up my new reef tank that I will want it as automated as possible due to a variable work travel schedule. In all honesty I really didn't do a lot of research and depending on your needs you may want something a bit different but based on my room configuration I was looking for a camera that could connect to the wireless internet, have a good streaming capability and easy to set up. I sort of lucked out as during a late night search on amazon.com I came across the dropcam. It has a simple apple product type of feel to it and was one of the easiest things to ever set up. If only reef tank controllers were this easy everyone would probably own one. Price was $149 and set up consisted of taking it out of the box, plugging it into my laptop (compatible with mac or pc) with the supplied usb cable they provide in the box. Once you go through a 3 part set up on your computer you mount the camera and that same usb cable has an outlet adapter that attaches to the usb port end so you can plug it into an electrical outlet. The cord comes with a fairly long cable, I want to say at least about 10-12'. The cam has a plastic piece that you use 3 screws to mount it to secure it to the wall. After that, you can clip the camera right into it and rotate and/or move the camera forward to change the angle how you like. From there you create your own cam link on the dropcam website. So what's the catch? If you want to record/dvr the data you can pay a monthly or yearly fee depending on if you want 7 days or 30 days of data stored. If you just want to stream it live there is no charge to do so. It has a zoom feature but it's pretty much all or nothing, you can't zoom in to different ranges and the pan and tilt is really a manual process with limited range depending on where you mount it. I can change settings from my phone (android and iphone app), view on my phone or anywhere I have internet access. For my purpose, it's exactly what I was looking for at a relatively inexpensive cost.
If you want to see it in action, I currently have it zoomed at about 3' from my tank. Lights come on at 3:30pm and you'll see reflection in the glass till it gets darker out. http://www.dropcam.com/p/PlankerReef
