Education Solution

Lecture capture fails when teachers stop using it

The more steps it takes to start, the faster it becomes shelfware

Four things schools report most often

Teacher and presentation are two feeds, and combining them needs either an operator or an expensive all-in-one
Recordings are huge and the server fills up before the term ends
Cross-campus sessions stutter, with audio drifting out of sync
Teachers plug and unplug cables before class, and one wrong port ruins the recording

Our approach

Capture every feed at once : the ZY-EH1304 takes four HDMI inputs - teacher, students, presentation
Record in H.265 : about half the bitrate of H.264, so the same disk holds twice the hours
Standard streams out : RTSP and RTMP, so the existing platform pulls the feed with no migration
Wireless casting : the wireless presenter is plug-and-play and supports domestic operating systems

Signal Chain

Capture, encode, campus network, platform, viewers

1 · Classroom feeds Teacher cam, student cam, presentation PC
multiple HDMI

→

2 · Capture Multi-channel encoder or capture card
H.265

→

3 · Campus network LAN or dedicated network
RTSP / RTMP

→

4 · Platform The school's existing resource platform
live and record

→

5 · Viewers Remote classrooms, student devices
web / app

If a capture platform is already in place, leave step 4 alone. Our encoders publish standard streams that the platform pulls directly - no migration required.

Recommended Products

Designed and manufactured in-house · OEM / ODM available · factory direct · 3-year warranty

ZY-EH1304 4-Channel Encoder

One input each for teacher, students and slides, with four streams per channel so recording and streaming run together.

Main capture unit

ZY-UCH801 HDMI Capture Card

Driver-free USB 3.0 into OBS: the cheapest way to start in a single classroom.

Low-cost recording

ZY-EH1304 4K Streaming Encoder

On-board display confirms status without a laptop - good for open classes and events.

Open classes and events

Wireless Presenter (domestic OS support)

Plug and play, so nobody memorises a cable order, and it supports domestic operating systems.

Classroom interaction

ZY-DH901 Multi-Interface Decoder

HDMI, VGA and CVBS outputs, so older projectors and TVs in remote rooms still work.

Remote classrooms

ZY-EH1304 Rack Encoder

1U chassis with a display, for central deployment across a whole teaching building.

Building-wide rollout

FAQ

How large is one recorded lesson?

At 1080p and 2 Mbps, a 45-minute lesson is roughly 0.7 GB; the same quality in H.264 is about double. Real size depends on motion - record one lesson with a demo unit to see your actual bitrate.

Does the teacher have to operate anything?

Ideally not. We design for plug-in-and-record, with start and stop driven by the existing platform. Any workflow that needs the teacher to press buttons every lesson ends up unused.

Does it work with the platform we already have?

Yes. Encoders publish RTSP and RTMP, which mainstream capture and resource platforms pull directly. There is no need to replace the platform.

Do you supply cameras too?

No. Cameras, including auto-tracking models, come from third parties. We handle everything after the camera output: capture, encoding, transport and recording. That keeps your camera choice open.
