Hey Guys, I have a store, where i have 6 cameras installed. Now one of these days I decided to go check the store, to overview my stock ( don't trust my employee) and when i went to the security room. To check the cameras it said storage is full with the warning sign blinking, and all the cameras showed a black screen plus a red line going to the cameras. now my question is was it still recording or was it completely shut down?
