Q: How many video sources can streamZ record simultaneously, and what is the maximum recording quality?

A: streamZ supports two recording modes:

• Standard Recording Mode: Supports up to two simultaneous sources (such as 1 UVC input + 1 HDMI input) recorded at up to 4K30 high quality.
• ISO Independent Recording Mode: Supports up to five sources recorded as separate files. The primary recording channel supports up to 4K, while system resources for the remaining channels are dynamically allocated.

Before starting recording, please go to System Settings > Recording encoding settings and confirm that the selected signal sources match the actual connected inputs. Otherwise, blank video may be recorded.

Q: What is ISO Independent Recording Mode, and when should I use it?

A: In ISO (Independent Source Output) mode, streamZ records each connected input source as a separate video file instead of combining them into a single screen layout.

This mode is ideal for scenarios such as multi-camera interviews, commercial livestreams, or productions requiring detailed post-editing. During post-production, you can freely select the best moments from each camera angle for greater editing flexibility.

For standard recording and archiving purposes, we recommend using Standard Recording Mode, which is simpler to operate.

Q: Can recording files become corrupted if they grow too large?

A: No. To prevent complete file corruption in case recording is interrupted unexpectedly, the system automatically splits recordings into segments every 3.8 GB and continues recording in a new file. Previously saved segments remain unaffected.

Q: Where are recorded files stored, and what file formats are used?

A: After recording is completed, files are stored by default in: Yunbao > Record

Files are automatically organized by year/month/day, and can be previewed, downloaded, or deleted directly from the web interface.

• Video format: .mp4 by default
• Audio format: .mp3 by default

To change the storage path, go to System Settings > Storage settings. The device must be restarted after modifying the storage path for the changes to take effect.

Q: What happens when the storage space is full? Will streamZ automatically delete old files?

A: No. streamZ does not automatically delete existing files.

When storage space becomes insufficient, a warning message will appear in the web interface. Recording will stop once the storage is full, but previously saved files will not be overwritten or deleted.

It is recommended to regularly check the remaining storage capacity (displayed in real time on the homepage resource statistics area) and remove or archive unnecessary recordings in time.

Q: Can streamZ record without an internet connection?

A: Yes. streamZ can still record normally while offline, but please note the following:

1. The recording file timestamps (modified dates) will display the factory default date instead of the actual recording time, which may affect file organization later.
2. Livestreaming still requires a working Wi-Fi or wired network connection. In offline mode, recording is available, but streaming is not supported.

Before recording for the first time, it is recommended to connect streamZ to the internet so the system can automatically synchronize the correct time and ensure accurate file timestamps.
