The ionized air carries electrical current and maintains that current, until something disrupts the air molecules. When the air molecules are disrupted, usually by smoke, the current drops, and an electrical circuit sound the alarm. Ionization smoke detectors are said to be cheaper to manufacture, but the downside is that they are prone to false alarms. They sound the alarm at the slightest degree of disruption in the ionized air, even from ordinary smoke in the kitchen. Types Of Smoke DetectorPhotoelectric smoke detectors or optical smoke detectors They are widely available, but recently smoke detectors using ionization technology and laser technology are making an introduction in the market. Photoelectric smoke detectors can detect slow, smoldering smoke the fastest, like the thick smoke when a couch or mattress is one fire. In comparison to smoke detectors using ionization technology, photoelectric smoke detectors set off an alarm earlier on slow burning materials. It can detect smoke faster in a large area or in a room with a high ceiling or rooms subject to temperature extremes. On the other hand the ionization type smoke detector is more sensitive to flames than to smoke. It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood.

Research conducted by the Rutgers University School of Criminal Justice showed that alarm systems help deter burglars. Another research conducted by the University of North Carolina proved that burglars would be hesitant to enter a home fitted with an alarm system. In fact, 31% burglars are likely to retreat from a home if they come across a security system. These figures reflect the effectiveness of home security systems. Types of home security systems The market is flooded with many types of security systems for households and businesses. Typically, you will find major components such as a control panel, alarm, sensors, and detectors in a security system.

For example, in accordance with some implementations, the camera 118 or 106 stores the most recent 24 hours of video footage recorded by the camera. In some implementations, portions of the one or more streams are stored at the camera 118 or 106 and/or the local storage device e. g. , portions corresponding to particular events or times of interest. In some implementations, the server system 164 transmits one or more streams of video data to a client device 220 to facilitate event monitoring by a user. In some implementations, the one or more streams may include multiple streams, of respective resolutions and/or frame rates, of the same video feed.
