Blink Video Doorbell + Sync Module 2 | Two-way audio, HD video, long-lasting battery life, motion detection, chime app alerts, Works with Alexa (Black) : desertcart.co.uk: desertcart Devices & Accessories

Review: Good quality from a small unit - Just moved house and wanted a video doorbell. The original intention was to buy an desertcart Echo Show 15 to use with it but desertcart seemed to have ceased production of that so we purchased the Echo Hub. Didn't want to subscribe to cloud storage and so the Sync2 module with a flash-drive fitted does the job for us. Setup was a bit tricky since both my wife and I wanted to receive notifications but once sorted it is working well. Used with Alexa, we get told there is someone at the door when the bell-push is used. We also receive notifications that motion has been detected (the field and sensitivity of motion detection can be altered so, for example, you don't pick up all passers by on the street). Recorded images are sharp, with a good field of view, in colour during daylight and B&W at night. An excellent little product in conjunction with the sync2 especially at the deal price we paid.
Review: Good performance - It does what it says on the box

### ⭐⭐⭐⭐⭐ Good quality from a small unit
*by J***Y on 18 November 2024*

Just moved house and wanted a video doorbell. The original intention was to buy an Amazon Echo Show 15 to use with it but Amazon seemed to have ceased production of that so we purchased the Echo Hub. Didn't want to subscribe to cloud storage and so the Sync2 module with a flash-drive fitted does the job for us. Setup was a bit tricky since both my wife and I wanted to receive notifications but once sorted it is working well. Used with Alexa, we get told there is someone at the door when the bell-push is used. We also receive notifications that motion has been detected (the field and sensitivity of motion detection can be altered so, for example, you don't pick up all passers by on the street).
