You will always have 7 days of Cloud backup to view that incident without the need of the SD card or any backup device. My favorite backup option for this special camera allows you to view and record the doorbell video right onto your existing security camera system. Other video doorbell camera manufacturers want to keep their cameras in a closed cloud system, meaning, they don’t allow the doorbell’s video streams to be recorded by another security camera system because that may deter you from possibly paying them a monthly fee to view your camera footage from their paid monthly cloud service which is really the bulk of their income. My sister has security cameras with the Ring doorbell added separately. She hates the fact that it’s a separate app to control. I added this to my new security camera from this store and it works with the camera system so I don’t have to leave the app to talk to whoever comes to the front door and be able to see where they are going on the other cameras. I also added a MyQ controller for my garage door so when packages come, I can tell the delivery guy to slide it into my garage when I open the garage door remotely. After I watch him do it on the doorbell camera and my other camera in the garage, I close the garage door from the MyQ app and everything is secure. Okay, there are some pros and cons to the video doorbell but it’s much better than the ring doorbell i had for two years for a couple of reasons. For one, the ring video doorbell came up with something that was considered very revolutionary at the time and that is the motion sensor which is really a heat motion sensor. I do like the fact that the heat motion sensor was meant to detect people not video motion and you can change the sensitivity to the heat moron but the Ring doorbell motion sensor does not do that very well.
