Honestly, my experience with Doorbot and its creators was so bad that I can’t help but harbor some animosity toward their operation. Yet, I want to be fair. Design is an iterative process. Perhaps they just need a few iterations on the theme to get to more generally usable product.
On the other hand, the description of the new product seems to be an incremental improvement from DootBot. Jump from 802.11B type Wifi to the more recent 802.11N type. Jump from VGA resolution video to 720p video, the baseline for HD. Abandon push-to-talk audio, ala Nextel of old, for something more akin to telephony. It’s basically a reversal of some of the bad design decisions embodied in the first generation product.
On the other hand, they still seem completely wed to their own “cloud service.” My experience with that was expect massive latency on call setup. Expect video only on occasion. I rarely even had continuous audio. On this basis alone you probably won’t receive that Fedex Express package you’re expecting on the first delivery attempt.
I’ve come to understand that my mistake with respect to DoorBot was expecting the kind of performance that I could more reasonably expect from any standards compliant IP phone. The DoorBot team clearly doesn’t have that sort of experience or appreciate that kind of performance. Even if that’s what separates the tools from the toys. DoorBot is a toy. Nothing more.
