TECH TRENDS
If there’s one thing the last few years made clear, it’s that the traditional classroom setup — a projector, a laptop, and a prayer — doesn’t cut it anymore. Students expect high-quality video whether they’re sitting in the front row or joining from their apartment. Faculty want systems that just work without calling IT every time they switch inputs. And administrators need infrastructure that scales across an entire campus without blowing the budget.
The good news? The Pro AV industry has caught up. The technology to build truly modern learning environments is not only available — it’s more accessible and more affordable than most people realize. Whether you’re upgrading a single classroom or planning a campus-wide rollout, the building blocks are the same. Let’s walk through them.
It Starts with the Camera
Lecture capture is no longer optional. Between hybrid learning, recorded lectures for review, and distance education programs, having a reliable camera in every teaching space is quickly becoming a baseline expectation.
Pan Tilt Zoom (PTZ) cameras are the standard here because they cover an entire room from a single mount point. No camera operator needed — modern PTZ cameras offer auto-tracking and preset recall that keep the instructor framed without any manual intervention.
The BZBGEAR BG-VPTZ-HSU3 is a compact 1080p PTZ camera available in 10X, 20X, and 30X zoom configurations with simultaneous HDMI, 3G-SDI, and USB 3.0 outputs — plus PoE for clean, single-cable installation. That multi-output design matters in education because you can feed the room’s recording system, a live stream, and a USB connection for video conferencing all at the same time. BZBGEAR also offers ceiling and wall mount brackets (BG-VPTZ-CM and BG-VPTZ-WM) purpose-built for classroom installations.
Atlona has built a strong reputation in the education space as well. The AT-HDVS-CAM is designed specifically for lecture capture and UC applications, with USB connectivity that works natively with Teams, Zoom, and WebEx. Atlona’s HyFlex Classroom solution pairs their cameras with room control via the Velocity touch panel system — a turnkey approach that appeals to institutions that want a unified platform from one vendor.
The key is choosing a camera that fits your room size, connectivity needs, and management approach. At BZB Express, we carry options across the spectrum.
Getting Signals Where They Need to Go
Once you’ve got a camera and source devices in the room, the next challenge is distribution. A typical modern classroom might have a laptop input, a document camera, a PTZ camera feed, and a room PC — all needing to reach a display, a recording system, and possibly a streaming encoder. That’s where matrix switchers and extenders earn their keep.
A matrix switcher lets you route any input to any output independently. The BZBGEAR BG-4K-44MA is a 4×4 matrix that handles 4K@60Hz with full audio de-embedding — a great fit for a standard classroom with a few sources and a couple of display outputs. Kramer and WyreStorm both offer comparable 4×4 matrices with their own management ecosystems, so the right choice often comes down to what control platform your campus is already standardized on.
For larger lecture halls or buildings with shared AV infrastructure, bigger matrices are available from multiple manufacturers. BZBGEAR’s lineup scales from 8×8 (BG-4K-88MA) up to 16×16 (BG-4K-1616MA), while Atlona and Kramer offer similar scaling options that integrate with their respective control and management platforms.
But what happens when your display is 200 feet from the switcher? HDMI cables tap out around 50 feet before signal degradation kicks in. That’s where extenders come in. The BZBGEAR BG-EXH-150C pushes 4K@60Hz over standard Cat5e/6/7 cabling up to 490 feet using HDBaseT — more than enough to reach any display in a building. Atlona’s HDBaseT extenders and WyreStorm’s EXT series offer similar reach with their own feature sets, including built-in audio return channels and control passthrough.
For spaces where running cable isn’t practical — think portable setups, temporary classrooms, or historic buildings where you can’t open walls — the BZBGEAR BG-Air4Kast delivers wireless 4K@60Hz transmission up to 164 feet with near-zero latency.
Scaling Across Campus with AV over IP
Here’s where things get really interesting for larger institutions. Once you move beyond individual rooms and start thinking about campus-wide AV distribution, traditional point-to-point wiring becomes expensive and inflexible. AV over IP changes the equation entirely.
AV over IP — Audio-Visual over Internet Protocol — means transmitting video, audio, and control signals over your existing network infrastructure. Instead of running dedicated HDMI or HDBaseT cables between every source and every display, you put transmitters and receivers on the network and route everything through standard Ethernet switches.
Atlona’s OmniStream platform is one of the most established solutions in education. It handles 4K AV encoding and decoding across existing network infrastructure, and the OmniStream Audio component adds AES67 and Dante support for networked audio distribution — a big deal for campuses that want unified audio and video routing.
The BZBGEAR BG-IPGEAR-PRO system takes a similar approach with 4K@60Hz multicast support and PoE on both the transmitter (BG-IPGEAR-PRO-T) and receiver (BG-IPGEAR-PRO-R). For campuses that need even more flexibility, the BG-IPGEAR-ULTRA adds seamless matrix switching and video wall capability in a single transceiver.
WyreStorm’s NetworkHD platform and Kramer’s AV-over-IP solutions round out the landscape, each with different strengths around encoding efficiency, latency profiles, and management software. Our team at BZB Express can help you evaluate which approach fits your network architecture and scale requirements.
Audio Is Half the Equation
It’s easy to get caught up in the video side of things, but audio is arguably more important in education. Students can tolerate a slightly soft image — they can’t learn from a lecture they can’t hear clearly. And for hybrid classrooms where remote students need to hear both the instructor and in-room discussion, audio quality is the single biggest factor in whether the experience actually works.
Ceiling microphones are the cleanest solution for classrooms. The Shure MXA920 is the industry benchmark — a ceiling array microphone with Automatic Coverage technology that captures talkers across up to a 30×30 foot area without manually aiming pickup lobes. It includes onboard IntelliMix DSP with automatic mixing, echo cancellation, and noise reduction, and runs on PoE for simple installation. It’s a premium choice, but for institutions building flagship lecture halls or executive training rooms, it’s hard to beat.
For conference-style classrooms and smaller rooms, the BZBGEAR BG-JTSCM22G12 is a 12-inch ceiling-mount cardioid condenser microphone optimized for conferencing applications — a more budget-friendly option that still delivers clean pickup for lecture capture and video conferencing.
Audio DSP (Digital Signal Processing) is critical for rooms that need echo cancellation, automatic mixing, and multi-zone audio management. The Kramer DSP-62-AEC is a 6×2 audio matrix switcher with built-in DSP and Acoustic Echo Cancellation (AEC) that handles the audio processing most classrooms need — microphone mixing, echo cancellation, HDMI audio de-embedding, and USB audio interface for UC platforms — all in a single PoE-powered box. It’s a popular choice for education deployments where Kramer is already in the ecosystem.
Speakerphones and portable audio fill the gap for flexible spaces. The WyreStorm HALO 60 is a true full-duplex USB and Bluetooth conference speakerphone with four noise-canceling microphones and 360-degree pickup — ideal for seminar rooms, study groups, and faculty meeting spaces where a permanent ceiling installation doesn’t make sense.
For distributing audio signals across longer distances — say, routing lecture audio from a main hall to an overflow room or recording booth — the BZBGEAR BG-AUD-TCS extends stereo, Toslink, and coaxial audio over Cat5e/6/7 cable up to 950 feet without signal loss.
Bringing It All Together
The best education AV systems aren’t built around a single brand or product — they’re built around a coherent design that connects capture, distribution, switching, audio, and display into a reliable workflow. A PTZ camera captures the lecture. A matrix switcher routes sources to the right outputs. Extenders or AV-over-IP endpoints deliver signals wherever they’re needed. And proper microphones and DSP ensure that everyone — in the room and online — can actually hear what’s being taught.
The technology is mature. The pricing is reasonable. And the impact on learning outcomes — for both in-person and remote students — is significant.
