Access Security Camera Feed and Previously Recorded Video

Need access to off-the-shelf surveillance cameras and previously recorded video to prove that we are telling the truth about a landlord who is a bad actor. The previously recorded and stored video will probably be sufficient depending on what is currently being stored, but access to any ongoing and new recordings will also be helpful. These guys are telling the cops and others that we are acting in bad faith in a landlord/tenant dispute and we need to show that we are the ones being wronged. Providing the credentials to the stored and ongoing video feed will most likely be enough, but we can’t be sure of that till we see what is stored in the cloud account of the cameras.
