I have like most (most ?) of you IP Cams. Mine are connected to a NVR and I can view my cams in real time through the Internet.
I tried to find a way to limit the access because in fact I don't need to access them all the time. That means my cams are online only if I need them.
my nvr is connected to a POE switch and my cams are also connected to that switch, so the local recording is enabled all the time.
My POE switch is connected to my router to have online access, BUT:
I put another switch between the POE switch and the router and this switch is powered through a monitored HE switch (in my case a Lutron Caseta Smart Home Plug-in Lamp Dimmer Switch, but any controlled outlet is fine, you know them all).
I created a virtual volume switch (but a dimmer switch can be also good) and a rule:
if the volume of this virtual switch equals 68 (1 of 100 possibilities), the lutron switches ON, and the Lan switch is now ON, making the cams visible through the net.
Of course, you can modify the rule to suit your paranoid behavior, like "if the volume equals the actual minute of the HE clock (1 of 60 possibilities, variable), then open the lan switch", etc.
And you can enhance the rule by closing the virtual switch for the night, or after a certain time on, when you leave, etc.
That means your cams are offline but if you adjust your virtual volume/dimmer and the value matches your rule, the cams are online.
You "hide" this virtual switch within a (passworded) dashboard and voilà !
Ok, sounds silly, useless or a good idea: unleash the comments
