Wire-Free, Indoor/Outdoor with Night Vision, I've never seen these reduced before, so you have a few hours to buy at these prices (Usually £199 for single and £410 for triple.)
These are reasonably well reviewed branded cameras, especially compared to other brands. The only issue is needed to change the battery often in busy places (like roads) where movement is detected.
Good app too.
Motion alerts - receive push notifications and emails if anything moves
Night vision - see what is happening even in the dark
Weatherproof - place Arlo anywhere, indoors or out
HD quality - enjoy sharp 720p live video and save those important moments with free cloud storage
