Channel deletion problem
Hey, so after I removed a camera from my NVR, I noticed that the old recordings still seem to be taking up storage space. What do i do to delete them? Also How do I change channel id to make them sequential?

Hi, Good day ! I have an old GVD M3004 NVR, sadly lost the HDD lock key. Is there another way to open the HDD bay without key? Planning to replace a new HDD. Thanks
Sure! We do sell the key for M3004. Just contact us on LINE or WhatsApp and send us the serial number. We’ll help you from there.

Hi, I have a GVD-M4006 and it was working fine until i reboot the system. I tried to login to HD NVR thereafter using Admin and default password but it does not work. Are you able to advise on what could be the issue here and what can I do to access to the cameras again? thank you.
Hi, we’re available on LINE and WhatsApp. Please contact us through one of these channels, as your issue involves a password. Also, kindly send us a photo of the monitor that isn’t working.

Hi there,
The behavior you're seeing is actually normal. The NVR software, by design, doesn't immediately delete old recordings when a camera is removed. Instead, the system will gradually overwrite the data through regular recording cycle, so the storage spaces will be reused automatically overtime. These leftover files also won't interfere with adding new cameras. Each channel is assigned with a unique and non-reused channel ID, and the NVR doesn't reuse old footage for new devices. If the skipped channel numbers bother you after removing cameras, you cam reinstall the NVR software and re-add the cameras in order. This will reset the channel IDs so they line up sequentially again.
Let me know if you have any other questions!
