According to Consumer Reports, professional monitoring costs range from $100 to $300 annually, plus the cost of equipment. In comparison, DIY system starter kits start at about $200. Also, professionally installed systems typically offer less flexibility. If you move, you may have to pay to have the system reinstalled at your new place. 3 options for DIY ersWant to take home security into your own hands?Let's
narrow the options. At the very least, you'll want to monitor your home's exterior using a smart camera, such as the Nest Cam, which sends live video to your phone and detects motion and loud noises.

The camera itself looks great and can serve as a decorative element in any modern style interior. It looks very much similar to a computer speaker, and if set close to PC, the camera won't be as noticeable to the strangers' eyes. The camera can record videos and stream them on your connected gadget online. For the moment the market offers a variety of video surveillance systems, which exemplify the rapid development of the industry. These security camera systems perform a wide range of tasks, from the surveillance on out to moving objects detection in a certain area
inside the premises. Depending on the intended use, security cameras can have different versions, be fitted with different controls and data processing equipment. In our review, we will examine the best security camera systems available on the market, give you some useful tips on how to make the right product choice and what aspects to focus on when picking a security camera equipped system. Wired cameras connect to security system equipment via wires. This connection type allows for connecting to an existing home network or corporate network, as well as granting access to security cameras’ control and data from various local equipment, or remotely via the Internet. High reliability and security of video data transfer to the recording equipment are the advantages of wired connection. These cameras can be controlled, powered and used to transfer the video via a single cable while
being insensitive to interference of mobile phones, Bluetooth devices, wireless network equipment and car alarm systems.

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. Ionization detectors tend to react slower, and may not warn people inside the house or commercial buildings adequately enough to be able to make it to the exit. So fire departments and legislative bodies recommended installing photo electric smoke detectors, or combination type detectors. The other feature that one may consider in a smoke detector is its gas detection capability. Incorporated in many of the newer models are carbon monoxide and carbon dioxide sensors that trigger an alarm when there is a high level of these gases present in the air. As stand alone detectors, they may be useful as alarms against dangerous gases, but may not be able to detect smoke out of
ordinary fires early enough. You’ll see that these wouldn’t be good fire prevention devices if that’s what you were looking for.
