Why is this a conversation. You wanted to cancel the contract on the cameras the cameras are being removed if flock is refusing to remove them cut them down throw them in a bin and say come pick them up before they get sent to the dump. The only question is are you going to have to pay out the rest of the contract or some kind of cancellation fee. The moment you tell this company take the cameras down that's the end of the discussion and if they refuse to send them to cease and desist notice and then send them a notice that these cameras are going to be removed by force and that the company is going to be responsible for any damages to those cameras for refusing to remove them themselves. At that point flock either removes the cameras or you cut them down and send them the bill for the demo work. This shit isn't complicated grow some fucking balls and just handle it
