Change your password Dag-Nab it!

We're getting reports in the field of folks having their Comrex web-based products altered by unknown parties--in some cases making VoIP calls to "sketchy" locations.

It's a good time for a public service reminder. Comrex products ship with a default password.  It's a really bad idea to leave devices exposed to the Internet at default passwords. We've started implementing nag screens like that shown to encourage this, but lots of older products are out there and their addresses are associated with URLs. That means they can be found via search engines.  Even if no URL exists, there are hackers out there running search scripts for VoIP devices, which our products certainly are. Change those passwords today!

LiveShot 1.2 firmware arrives

When our LiveShot video codec shipped late last year, our entire focus was on video quality, and we'd managed to implement what we felt was a respectable first-go at a "network manager". That's the bit that makes the Internet work like it's "not the Internet". I.e. it handles the bad things about IP networks automatically and keeps things solid. With our extensive background in audio-over-Internet, we felt the stuff we'd learned over the years would be good enough for a first effort.


Well we learned quickly that moving a megabit or two over the Internet is a lot more challenging than moving a hundred kilobits.  We've been deeply sequestered most of this year hammering on that aspect of the product, and we're proud to say we're releasing new firmware that does, in our humble estimation, a fantastic job of dynamically adjusting all sorts of parameters to keep your video rock solid when your network isn't so much.

LiveShot 1.2 has a changelog that's about a mile long, but the heart of it involves a much smarter, more dynamic way of adapting the video to maintain stability. This involves better modem sharing (in applications that use a pair of modems) and dynamic adjustments to bitrate, resolution, and framerate when things go south on the network. We've spent the last couple of months taking it to a variety of ultra-congested locations and we're very happy with what we see. We think you will be too.

The question I get asked often is "When will these enhancements be coming to the audio hardware". The answer is: 2014. We're actively on that project and will have hard data around the time of the NAB show in April.
