based on my research there is no cloud server or cloud function on this camera, you might have been scammed bro. ( Don't take my word for it just yet, until i can actually verify the exact model )
which also explains why the video does not work after you removed the sd card.
can you please take a picture of the product and maybe the box, so i can help to see if i am able to find anything?
Apologies, due to post count Im unable to upload links or images..
But I found a sticker on the back of my camera with the model number - V380-Q5, resolution 720P. The seller did not provide me with any box when he came to install and mount for me.
Yup I'm also suspecting that it runs on the SD card instead of cloud.
His reply was: The micro sd card is being converted to be a micro chip for the camera technical support and use it as a backup. As this is a security camera, we need to have this security measure to ensure backup when there is a failure to the internet. I believe you have pulled out the microsd card to realize that the storage place immediately disappear, that is why the microsd card is being allocated to the camera. Once you pull out, the access is gone. Naturally the storage will not be shown.
He also told me that cloud storage function is the "download" function whereby Im allowed to download the footages from my mobile phone and challenged me to go to Sim Lim to request their sellers to show me that microsd card cameras are unable to download the footages directly to mobile phones.
Kind of doubt much of what he told me.
And now to think of it, he told me that this camera is 960P! When the sticker says otherwise ._.!
