The team chose the RevoLabs Fusion product because of its 128-bit proprietary encryption that provides security from eavesdropping, a long battery life, and easy integration with the LifeSize system. According to RevoLabs, the company provides “all of the necessary cables to plug into any of the major videoconferencing solutions, including LifeSize, Polycom, Sony, and Tandberg.”

Burnham says he also liked the microphone system’s echo-cancellation technology. “The ceiling in the meeting room is a hard deck; there is no acoustical treatment, so intelligibility can be compromised without echo cancelling,” he says.

To set up for a meeting, six Revolabs boundary microphones are placed at regular intervals along the meeting tables. Both of the solo wearable microphones are placed at the front of the room for the person or people who are leading the meeting.

The school also purchased two LifeSize Express with Focus units to send out to meeting participants who cannot make it to campus in-person. The units are packaged in a custom Pelican hard-case for protection during shipping, as well as a LifeSize Focus HD camera with built-in microphone, an LG Electronics 19in. LCD HD monitor with built-in speakers, and setup instructions.

According to Burnham, the far-end participant needs a DSL or cable modem connection to participate via video. The codec adjusts to available bandwidth and can deliver a quality picture down to 256kbps minimum. Far-end participants do not need a RevoLabs microphone system because they can use the microphone that is built into the Focus camera. “These shippable units mean that the meetings can be in high-definition video on both ends,” Burnham says.

The school also invested in a LifeSize Transit Server 2.0, which is used to manage what Burnham calls “the far-end firewall problem”. The unit lives in the university’s server room on campus. “It serves as a gatekeeper on the network and facilitates far-end units traversing their firewalls, using H.460.18 and H.460.19 standards” Burnham says. “It helps to facilitate H.323 video calls across enterprise firewalls that are not under our control.”

Currently, the system is used once or twice per month. Burnham notes that the meetings have gone smoothly and without failure. The mobile unit remains in the secure meeting room at all times, which is alarmed when not in use.
