fall detection devices
Burglars want to get in and out of a house as quickly as possible. The longer it takes to enter a home, the more likely someone will notice and call the police. So the harder you make it to gain entry, the better. Unfortunately, many people make it way too easy for a criminal to
burgle them. Some research suggests that about 30% of all burglaries are through an unlocked door or garage. While it’s easy to pick a lock, it takes much more time than walking through an unlocked door or window. That’s why you should always lock all of your home’s potential entry points; it’s the simplest way to add a buffer of time. Install a home security system. The research shows that homes without a security system are three times more likely to be broken into than homes with one. Home security systems obviously deter would be thieves by bringing audible attention to their break in attempts. They also automatically dispatch the police to your home though it’s important to note that it could be up to 30 minutes to an
hour before they get there.

Turn the device around and you can see four narrow, but fairly long ventilation holes on the edges, four holes for ceiling mounting, a battery door and a micro USB connector in case the smoke detector needs servicing. This is available for the battery powered Nest Protect, but, of course, you can also purchase the wired variant, which will have additional AC connector
pins on the back side to attach a 230V cable connector. The device itself is not really bigger than the average smoke detector from the market, measuring 1. 63 x 5. 28 inches and the install process follows the same steps: after choosing the rooms in which you’re going to install the Nest Protect at least in every room which has a fuel burning appliance, you need to make sure there is a minimum of 10 feet from any cooking appliance and avoid placing it on a corner you can choose either a wall or the ceiling. Then, you need to take the provided backplate and fix it to the wall/ceiling using the four screws and afterwards, just connect the smoke detector to the backplate using a circular motion if you have the wire powered version, the installing process also includes connecting the device to a power source, but, it’s ideal that this is done by a qualified person, to make sure the installation is made in accordance with the country or state’s regulations. The way to differentiate the first and the second generation of Nest Protect is by verifying if it has a battery door the Nest Protect 1 does not have one, verify the back plate the second generation has a round backplate, while the first has a square plate and the easiest one is to look at the edges of the device the second generation has rounded corners all around the case, while the first gen has straight edges. Right now, on the market, there are three types of smoke detectors: those that use
ionization sensors, those that use photoelectric sensors and lastly, those that use both type of sensors also called dual sensor smoke alarms. The Nest Protect, theoretically, falls into the last category, but things are a bit more complicated because it doesn’t have a ionization sensor, but it does use the Split Spectrum Sensor which nullifies the need of the radioactive ionization sensor as you know, it detects smoke produced by flaming fires which burn at a fast rate so, if the ionized air is disrupted by smoke, it triggers the alarm. 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. Now, the Split Spectrum Sensor should detect both the flaming fires and the smouldering ones, by adding a blue LED light at a wavelength of 450nm to look for small particles which are an indicator of a rapid, fast burning fire and keeping the usual photoelectric sensor to detect smouldering fires.

A built in spotlight also enables color recording at night, and it has dual microphones for better audio. Plus, the Arlo Ultra’s base station will be compatible with the company’s smart
home security kit, due out later this year. All of this will cost you, though: A single camera with the hub is $399, and extra cameras are $299 each. And if you want to save 4K videos, it’s an extra $1. 99 per camera per month, on top of the $9. 99 monthly plan, the latter of which is waived for the first year.

The Arlo Pro 2 can be
plugged in or run off battery power, and can last for up to six months without needing a recharge.
