The OC810ADT Outdoor Camera has been replaced by the OC835ADT HD Version. But if you want this older version or if you do not have the new Black Netgear Gateway you will need this one since the new hd outdoor camera only works if you have a newer gateway. The OC810 ADT Pulse Outdoor Camera was the best way to see outside your home or business when you are not there or if you want to record what is going on (now the OC835ADT is) . Since you can have up to 10 ADT Pulse Cameras, it is nice to have at least a few outdoors.
