Spotlight camera during power outage?

I do not currently have a security system in my home and am researching various makes and models to find what fits my needs. I like the LED Spotlight Cam with the Solar Power option. A few questions, if I may -- -- Since this is powered by a solar cell and a battery backup, is it "safe to assume" this camera would function as normal during a power outage? (Assuming, of course, my home wifi is also on a functioning UPS backup.) -- If wifi is still available, would it still upload video and otherwise detect and alert?
