Vivint Doorbell Camera – Vivint, the security giant best known for door-to-door sales, says its new Doorbell Camera, released in 2015, has been the most successful product rollout in the company’s history, with more than 100,000 units sold in the first five months. In fact, Vivint CTO Jeremy Warren tells CE Pro that the company invested heavily to create its own front-door product because the category is so compelling to consumers. The unit looks like a thicker version of a traditional vertical doorbell, with a form factor that allows placement on a standard door frame. Other units on the market are square, round or otherwise unsuitable for thin frames. Vivint’s can sit right where the old doorbell once stood, powered by the same two wires that connect to the doorbell chime. The camera on the product provides a sweeping 180-degree view and includes night vision for 24-hour surveillance. There’s two-way talk via the built-in mic and speaker and integration with Vivint Sky touchpanels. Will the design and functionality of a doorbell camera really lure customers to Vivint for whole-house security and automation? “Yes, we think so,” Warren says.
