Amazon has put many of its Ring video doorbells and cameras on sale for up to 35 percent off. One of the most notable price drops is for the Video Doorbell 4, which has returned to a record low of $170. The Video Doorbell 4 has color video previews and a handy Quick Replies function. It offers 1080p video and improved battery life over previous models, Amazon claims. You can run the Video Doorbell 4 wirelessly or hook it up to existing doorbell wiring. It can connect to 2.4 GHz and 5 GHz WiFi networks and it has interchangeable face plates.

Just a couple of months after Ring unwrapped its new, radar-enabled aerial view for the Video Doorbell Pro 2, the Amazon-owned smart brand is now rolling out the clever technology to its updated wired floodlight. At the same time, Ring says it's bringing a color version of its pre-roll video feature to a fourth generation of its battery-powered video doorbell. Slated to ship on May 6 for $250 (you can preorder starting today), the Ring Floodlight Cam Wired Pro will boast both Bird's-Eye View and 3D Motion Detection, a pair of features powered by radar rather than infrared motion sensors. Meanwhile, the Ring Video Doorbell 4 is set to arrive April 28 for $200, and it will add color to the pre-roll functionality that debuted on last year's Video Doorbell 3 Plus. An upgrade to 2019's well received Floodlight Cam, the revamped Floodlight Cam Wired Pro arrives with the same 1080p video resolution while adding HDR for a needed contrast boost, along with a 140-degree (horizontal) by 60-degree (vertical) field of view.
