It seems to me that this is not the most reasonable solution if we take into account the price and quality. The quality of the system is certainly good, but the functionality is extremely reduced. You can take a look at a similar ajax, which has more functionality at a lower cost for a kit with smoke detectors, motion sensors and cameras. At the same time, you also get an application with which you can get all the information from the cameras in the house and can receive push notifications when sensors and alarms are triggered. I mean, you should think about other options.
