Hi! We were looking to add another camera like the ones we bought here before to our network, but they seem to be out of stock. Any idea when you'll get more in (or the equivalent)?

Model was IPPTZ-EL2IR250L30X-AT, but I think IPPTZ-EL2IR250L30X-E would also work or anything with equal capabilities? (IP PTZ 30x optical zoom 2 MP IR etc) 

Thanks!
