Each camera will need a 120 volts AC power outlet to plug into so giving some thought into placement will need to be planed. The DVR itself will need to a have a Ethernet wire run to a router to give the system network ability. The cameras themselves automatically sync with the DVR once everything is plugged in. Resolution of 720P can be watched or recorded. If setup on the home network apps can be used to watch the cameras from mobile devices. …….

Smoke detectors must indicate that it has met Underwriters Laboratories UL Standard 217 and carbon dioxide detectors must meet UL Standard 2034. UL conducts certification training on every electrical appliance. Smoke detectors can only alert you if there’s fire. The rest depends on the homeowner’s preparation and other fire prevention safety measures. Equip yourself with fire extinguishers and sprinklers, too, if necessary. Photo Electric or Optical Sensors They are triggered by smoke disturbing an existing beam of light inside the detector. When smoke is not present, the beam from a light source inside the device travels in a straight line to a detector, but when smoke particles enter, some of the light is scattered and triggers the electrical circuit that sounds the alarm. Air Sampling Detectors These have sensors that are capable of detecting microscopic smoke particles in the air. They actually draw air into the detector and passes it into minute pipes that lead to a laser optical device that has the capability to detect minute particles of combustion. When the laser detects the unusual content, it triggers the alarm. Combination Type Detectors It use both ionization and optical sensors, as mandated by some states.
