A highly sought-after feature today is remote access to camera images. Both analog and IP cameras can be accessed remotely. The big difference is that IP cameras are already adapted for this feature, while analog cameras will need to be connected to a DVR that will convert the analog signal into a digital signal, so that only the transmission of images via the internet is possible. process and installation are easier with IP cameras. Some even come with their own cell phone applications to facilitate access. It is good to warn that whenever a camera or DVR is connected to the internet there is a risk of invasion by hackers.
