Security has become a very "hot topic", and both external and internal security cameras should be an important component of any security protection plan you either currently have in place or one you are comptemplating installing. Break-ins involving vandalism and/or theft, as well as shoplifting in general can be extremely expensive. This unfortunate expense could amount to much more than the cost of a security camera system. Important to note; security system cameras can be monitored remotely via the internet, when the NVR POE Switch is connected to an ethernet source.
