However, no other security camera in our review has a battery backup.

Tops among these is the First Alert SA320CN Est. $20, a dual sensor, battery powered smoke detector that earns positive feedback overall. It's been tested by Consumer Reports, and earns the top rating for detecting both smoldering fires and flaming ones, though not a recommendation presumably because it cannot be interconnected with other alarms. User reviews are positive, including a 4. 6 star rating at Home Depot, and recommendations from 98 percent of the nearly 100 owners that leave reviews. The ionization/photoelectric sensor smoke alarms above use standard batteries. However, they are inappropriate for those who live in a state or city that requires that battery operated smoke detectors be powered by sealed 10 year batteries. In that case, we suggest the First Alert SA3210 Est. $50. It's very similar to the First Alert SA320CN save for the power source a sealed 10 year lithium battery that complies with regulations in those areas that require them. It's not been professionally reviewed, but the handful of user reviews we spotted scattered on sites across the internet have largely been positive thus far.
