Webcams 7: VDO360 Serious Webcams For Business

It was around a year ago that went on the hunt for a USB 3.0 webcam, only to find that they were essentially nonexistent. In my quest what I discovered was a range of products beyond the familiar consumer webcams. These are serious webcams for business, offered by companies like VDO360.

That companies’ initial product, the VPTZH-01 HD USB PTZ Video Camera, was novel for its VISCA compatible pan-tilt-zoom (PTZ) capability. It was introduced at around $1399, a price that was heralded as a breakthrough at the time. Award-winning in fact. The current street price, as exemplified by Amazon, seems to be $999.

The VPTZH-01 HD USB PTZ Video Camera is a USB 2.0 connected device, with all that entails. The sensor is capable of delivering images up to 1920 x 1080 pixels (1080p.) Most applications will only manage to access a 1280 x 720 pixel (720p) stream since they are taking uncompressed frames from the camera.

Applications that are sophisticated enough to setup the camera to deliver a stream of MJPEG compressed images will be able to get full 1080p quality for the effort. The MJPEG compression overcomes the bandwidth constraint of the USB 2.0 connection to the host computer.

Making Some Noise About Noise

Snapper-lawn-mowerThis morning my normally tranquil home office was pierced by the sound of a neighbors lawnmower. The lawnmower, while aggravating, is just the lead-in to that most vile of power tools…the leaf blower. Leaf blowers should be outlawed.

All of this has thinking about noise. In even modest amounts, noise degrades our ability to communicate. Beyond simply annoying, it hampers productivity. Therefore noise has very real costs. Nowhere is this more true than in the case of conference calls or video conference calls. These are cases where extraneous noise should be avoided.

The classic conference call wisdom, good advise to this day, is that all participants to should diligently mute themselves when not speaking. People being what they are, many do not know of or act upon this belief.

When using a managed conference bridge, like ZipDX, the call moderator has the ability to mute a noisy participant, ensuring that their local acoustic reality doesn’t degrade the call experience for everyone. That’s great, but it really just allows the moderator to compensate for the fact that someone on the call is exhibiting poor conference call etiquette.

A Dead Ringer For DoorBot

DoorBot-Looking-Left.jpgThis week has seen the team behind the DoorBot pseudo-smart doorbell announce their second generation product. In so doing they’ve renamed themselves Ring.

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.

The LG HBS-730 Bluetooth Headset Sucks Rocks

Nexus7-Headset-BT-xmitter verticalAs was mentioned a few weeks ago, I’ve been looking for a Bluetooth headset primarily for listening to music. This is a very different use case for me. For years I’ve reserved Bluetooth wireless devices exclusively for use with my mobile phone, making phone calls.

I bought one of the leading devices in this class, the LG HBS-730. It was recommended by several friends, so I thought it would surely be great. Except that it wasn’t. Compared to my reference, the Etymotic HF5, it sounded dull and lifeless when paired to anything I had on-hand.
