The incident comes as ride hailing services such as Uber and Lyft are facing intense questions about the security of their customers. University of South Carolina student Samantha Josephson was killed last month after mistakenly getting into a car that she thought was her Uber ride. Uber said in a statement it was devastated about the "unspeakable crime," and that it's working with the universRead More – SourceLorex offers two types of wireless security cameras wireless and wire free. Both types wirelessly trasmit data to a receiver connected to a security digital video recorder DVR recorder. Wireless security cameras, which can be used with most Analog MPX DVR systems, need to be plugged in, while a wire free security camera is powered by rechargeable lithium ion batteries. Another main difference is that wireless cameras are designed for 24/7 monitoring, while wire free cameras only turn on when motion is detected.

One of them is the First Alert P1010 Micro Smoke Alarm, which, while it has all the expected elements of the traditional smoke detector, it is rather unique from the design point of view yes, I know, First Alert again, but, in truth, there are not that many reliable options on the market right now. Furthermore, besides the transparent Silence / Test button positioned ion the side, there aren’t any other elements to break the minimalist design continuity. At first glance, you’d be tempted to simply position the smoke detector on a shelf and not bothering installing it on the wall or ceiling, but since you want it to detect the smoke as fast as possible, you should mount it on the ceiling and a bit further from the corners of the room it’s also ideal to keep it at least 15 feet away from a fuel burning heat source, so it won’t trigger those annoying false alarms. That being said, the installation process is simple and intuitive: all you have to do is remove the card from the bottom of the mounting bracket, attach the ring to the ceiling or wall using the fixing anchors they’re provided inside the package, fortunately and afterwards, simply rotate the alarm into place. The most popular types of sensors that are used to detect the smoke particles are the ionization sensors and the photoelectric sensors some manufacturers have developed their own proprietary sensors to detect more than one type of fires, such as the case of the Nest Protect with its Split Spectrum sensor. The ionization sensors are used to detect the small particles from fast burning fires, but because of their nature, they’re more prone to false alarms these type of sensors are usually found built into older smoke detectors. The photoelectric sensors can detect larger particles, so it is a lot more useful for smouldering fires those which have not yet erupted into flames, so they’re better for an early detection and are less likely to trigger false alarms. The First Alert P1010 uses the aforementioned technology, so it has a beam of light inside a small chamber which does not directly hit the photoelectric sensor, but, the moment smoke particles enter the device through the holes in the metallic section, the light gets diverted and it will immediately hit the sensor, thus sounding the alarm. In case a fire is detected, you will be able to hear three beeps, pause, three beeps, pause and repeat, while the LED light will flash rapidly – the LED is located inside the Silence / Test button the horn is loud, reaching up to 85 db, 10 feet away from the device – if you have a hearing impairment, it is advisable to have a look at smoke alarms with built in strobes. 1. Which type of sensors are equipped on the smoke detectors?Smoke detectors can have two types of sensors: ionization sensors, photoelectric sensors or both usually called dual sensors.
