The camera is also conveniently battery powered from the included AA Lithium batteries, with a 2 year lifespan. Cloud storage is also totally free, without any monthly fees or subscription contract, so you can go back and watch old footage if you ever need to check something out. You can create a Blink XT home security system with just one camera if you only want to keep an eye on the front door, or you can include up to 10 cameras on one Blink Sync Module. This camera is also weatherproof, so you can put it outside. While both the Ring Spotlight Cam Battery and Spotlight Cam Solar streams high quality, crystal clear video footage, it takes things a step further by also including a 110 decibel siren, which you can sound if you have suspicious activity happening around your home. It’s perfect for catching porch pirates.
