The Ring Stick Up Cam is currently on sale for $55 via Amazon, a discount of 45 percent and the lowest price ever for this well-regarded security camera. This deal is available to everyone, unlike the previous Prime Day offer. The camera is standard but versatile, easily mountable on various surfaces and movable. It features two-way communication through a proprietary app or compatible Echo devices like the Show, allowing users to check the camera feed remotely. There are two versions of the camera available in this sale based on power source, with one using a removable battery pack for easy mounting and the other plugging into a power source for continuous operation. Subscription to a Ring Protect Plan is required for cloud storage of recorded footage, with plans ranging from $5 to $20 per month. However, these cameras lack some features found in the Pro model, such as radar detection.
