How to have all of your cameras record on command!
As I mentioned in another post, after six years with SS3 I finally broke down during the recent 40% off sale and purchased a key fob. My intention was to keep it on the nightstand, next to the existing panic button, and use it when the inevitable siren start blaring, hopefully for a false alarm, in my hand while on the phone with dispatch.
I hit the off button while the system was already off, and, duh (at least for me) all of my six cameras began recording, and about a minute later were on my timeline and I could replay them. Tada moment, again, at least for me, if I want all of my cameras to record on command just hit the "off" button on my keyfob. Old dogs can learn new tricks..woof.
