8. The Y cam Indoor HDS is the only camera in our review with free cloud storage. Field of ViewIf you choose a camera with a very wide field of view, at least 160 degrees, you can expect to see every part of the room in front of the camera. The widest field of view in our review is the D Link DCS 2630L at 180 degrees. A wide field of view, which the majority of the cameras we reviewed have, is anything larger than 80 degrees, and it works best if you mount the camera high in a corner that overlooks the room. Digital ZoomDigital zoom allows you to select part of the video and enlarge it.

11b/g/n standard and Bluetooth Low Energy technology and, in case of an emergency, all the devices will speak at once telling you the location of the triggered alarm the devices shouldn’t be more than 50 feet apart from each other. The wired and battery models can be connected wirelessly up to 18 and you can also connect the Nest Protect with other Nest smart products such as the Nest Learning thermostat. Now, let’s talk about the elephant in the room or the Nest!: the security and privacy of your data. As you know, Nest is owned by Google, so this already makes people more cautious about their privacy. There has been a reported backdoor more than a couple of years ago on the Nest thermostat, but the Nest Protect was and remains unaffected by the IoT vulnerabilities and there are many. Now, Nest admits on collecting data from your system to analyse the average battery life, it records data about any adjustments you make to the product and the history of all changes, but it insists that all collected data is not sold to third party companies and the info may be shared but not before the user gives explicit permission to do so. The First Alert Onelink Safe and Sound is the newest smoke and Carbon Monoxide detector from the US based manufacturer and it is the second attempt at creating a worthy competitor to the widely popular Nest Protect 2nd Generation. I purposely skipped the first generation of OneLink because it was a mess software wise the app was unstable and the device would constantly trigger false alarms, so the company has worked hard to fix these issues and hoped that this new device would receive more positive feedback from the audience. To further set it apart from its predecessor and its competitors – which are not that many, the First Alert Onelink Safe and Sound has included a built in speaker and has embedded Alexa Voice Services, while also keeping the compatibility with Apple’s HomeKit of course, this has driven the price up significantly. Since the Halo Smoke Alarm got discontinued and the Cloud based support got closed as well, I can understand why people may be reluctant with giving start ups a chance and instead may prefer to go with a more mature company that’s been in the business for longer and that’s where the likes of Nest and OneLink Safe and Sound come into play and remain overall favourites in spite of the usually higher price tags. The First Alert Onelink Safe and Sound detector features a fairly large oval case made of plastic, with the front side divided into multiple inner sections by narrow plastic bands, the device mostly being covered by lots of puncture holes the middle section is slightly elevated.

The photoelectric sensors is used to detect any smouldering fires that uses a light beam which, normally does not hit the sensor, but when smoke scatters the light particles, it will hit the sensor, therefore triggering the alarms – this method is used to detect a fire in its early stages, therefore reacting a lot faster.

Users of this security system do not need to adjust cameras because it’s day and night mode are automatic.
