Floodlight cameras are helpful for spotting (and ideally, deterring) intruders, but they typically require some kind of wiring. Even Ring's model still requires a link to a floodlight system. Arlo, however, thinks it can one-up its rivals. Its new Arlo Pro 3 Floodlight Camera is billed as the first truly wireless option of its kind -- you can put it where you need it without any messy connections. About the only hassle is having to recharge the battery.
