Heat sensors are designed to detect a rapid rise in temperature. Theyalso have a feature that sets off an alarm when a fixed temperature is reached. Smoke detectors do not react to heat but use one of two common sensordesigns to detect smoke. An ionization type of detector forms anelectrical path inside a small chamber with a very small amount of radioactivematerial. When smoke enters the chamber, the particles attach themselves to theions and change the electrical current flow. A photoelectric type ofdetector works by using a photoelectric cell and a light source. The light doesnot usually reach the photoelectric cell, but when smoke is present the light isdispersed and reaches the photoelectric cell, triggering the alarm. The maindifference between the two types is photoelectric types are more sensitive tolarge particles and ionization types are more sensitive to small particles. Modern home design should include at least one of each type. Smoke and heatdetectors should be located in each sleeping area and on each story of the homeand placed on the ceiling or on the wall 6''12'' fromthe ceiling. When it comes to apps that control your home security system, you should determine your needs.

additional door/window sensors, pet friendly motion detectors, flood detector, connected smoke alarm, Nest thermostats, wireless cameras, etc. , the equipment belongs to the customer and does not have to be returnedwhen the service is terminated. In order to separate themselves from the pack, the SimpliSafe website highlights some major differences between them and some of the larger home security companies. One of the main differences is that SimpliSafe claims no hidden fees and requires no commitment or service contract. As highlighted in the New York Times articles on SimpliSafe, many home security systems require up to a three year contract that can costthousandsof dollars, and often have add on fees that raise the actual cost of the service from what is stated as the monthly home security monitoring fee. SimpliSafe requires no such contract and no auto renewal fees. Another important difference between SimpliSafe and some of the more traditional home security systems is that SimpliSafe is 100% wireless. Not only does that mean a less expensive and difficult installation process, but more importantly the system cannot be shut down by a clever thief with wire cutters. In fact, the home security installation is so simple that the customer can begin installing the system in as littleas 5 minutes, as shown in a helpful video on the website. This is a nice incentive for those folks who don't want a hefty installation charge or permanent wiring added in their home. Of course, it could also be a negative for people who don't trust themselves to install the system on their own.
