Eight infrared LEDs and new algorithms have been added to improve night vision and motion detection. Nest Cam is smart enough to tell the difference between a torch and sunlight, so it won’t get confused and switch to day mode if an intruder shines a light at it.  The Nest Cam costs £159 and will be available to purchase from a range of retailers including Amazon, John Lewis, Currys, PC World and B&Q in July.  For an additional monthly fee, users can subscribe to the Nest Aware cloud service, which allows them to scroll through 10 days of content for £8 per month or 30 days for £24 per month.  All video is stored and processed in the cloud. This allows Nest Cam to provide more accurate alerts when it detects movement in the house, and identify areas where common false alarms occur, like shadows moving across ceilings.  Users can make and share up to three hours of clips, including timelapses, and create custom 'activity zones' around areas of interest – such as a door – so they can be alerted to anyone coming in or going out.  "The cloud is not just used for video recording, but when you stream back to your phone, it can also be used for image processing – whether it's algorithmic or to enhance resolution in certain areas or just get more depth, and you do that in real time," said Mr Paillet.  The Nest Cam has a built-in microphone and speaker, so the user can talk to whoever is in their home via the smartphone app. Nest said that all data is encrypted in the cloud and while it is being transmitted between devices, to ensure it remains private and secure.  Although the primary purpose of the camera is home security, Nest also sees the potential for it to be used as an entertainment device. Nest is piloting the ability for users to stream directly to YouTube Live from a Nest Cam.  Unbox Therapy creator Lewis Hilsenteger, American videographer Devin Graham and YouTube personality Justine Ezarik have all been taking part in the pilot, giving viewers a behind-the-scenes look at their lives.  Nest said that some of the most popular camera feeds will stream directly to Nest’s own YouTube channel, so people can see live video of everything from puppies to scenic landscapes.  The launch of Nest Cam coincides with a refresh of the rest of Nest's product portfolio, with the launch of the second-generation Nest Protect smoke alarm, new features for the Nest Learning Thermostat, and a new app for Android and iOS.  The new Nest Protect includes a sensor that can detect the small particles generated by fast-burning fires, as well as the large particles from slow-burning fires. It also carries out automatic safety checks and allows users to silence false alarms from their phones.  The Nest Learning Thermostat is getting new features via a software update, including safety temperature alerts to warn users if their home gets too cold, and the ability see smoke and carbon monoxide alerts from their Nest Protect on their thermostat screen.  Meanwhile the new app has a new look and added features that make it easier to control Nest products, as well as the ability for users to view live videos of their home via a Nest Cam and record clips.  "We’ve built a portfolio of best-in-class products that each stand on their own while doing more together," said Nest chief executive Tony Fadell. "The result? Energy saved, lives spared, and countless memories recorded and shared.”  The new Nest Protect costs £89 and is available for purchase at nest.com. The new Nest Learning Thermostat software will begin rolling out today and will take up to two weeks to reach Nest customers. The Nest app is available for free in the Google Play Store and iOS App Store.  The news comes after French startup Netatmo launched a new smart home camera earlier this week, that will compete directly with Nest Cam.  Netatmo's camera, which is called Welcome, costs £199, and features proprietary face recognition technology that is capable of recognising registered people's faces even if it only catches a glimpse of them as they walk past. It does not require a cloud subscription.  Follow the Telegraph on LinkedIn. Share this article with your network.
