Doorbell Camera Stolen January 30th (I believe)

Is there any way to retrieve footage from the last moments the doorbell camera was powered on and online even though it will most likley be the 30th of January (3+ months ago). Everything I have read says that unless it's downloaded within the first 7 days - it is not able to be accessed....But, how does either the defense or prosecution aquire footage from the previous 6+ months ... would the plaintiff or defendant have had to have downloaded the footage withing the alloted time period of 7 days .... I know some doorbell camera systems will store footage in the cloud for up to 180 days (I believe) but from everything I have read on here - 7 days is the limit and then its....."deleted"?? Or is it stored somewhere that is only accessible when legally nessesary...? If needed I am willing to work with the sheriffs department to coordinate obtaining the footage if it is at all possible.....help??....lol
