Camera jumps off line.It delays all time.People be at your door and when you answer it,then the door bell goes. The same with outside cameras, they walk right by it and it doesn't ding. The door bell was not right. They mail me one and said get someone to fix it. If you have a business and people paying for your equipment. You should have your technicians to come out.Free of charge. They need to come check they own equipment. They want to charge you.I don't understand 😒 🙄
