This doorbell camera allows you to insert an SD card up to 128G that can give you up to 6 months of video storage viewable from your phone, tablet or computer remotely from anywhere. You also get free instant Cloud service so you can capture a snapshot of anyone coming into the camera’s view with a more precise motion sensitivity and grid placement you can control from the camera’s app to pick up motion in any area in the camera’s view you designate as important. That Cloud clip is crucial if the doorbell camera is vandalized. 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.
