Smoke detectors are made with different kinds of sensors that detect excessive smoke when it is present and gives out the alarm, or triggers the automatic fire control system. It is best that homeowners are able to see the difference among these different types and see how they work, before deciding on which ones to buy and install in the house. The type of sensor installed in a smoke detector may also dictate the price range, since there are sensors that have more expensive components than those of the other types. Among the types of sensors presently used by several manufacturers of smoke detectors are the ionization type, the optic sensor – also called photo electric sensor, the air sampling sensor, and combination type sensors. A smoke detector with an ionization type sensor uses what is called radio isotopes that produce ionization in the air. The process is quite technical, but what this type of detector contains is ionized air molecules in a chamber inside the device. 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.

Likewise, these devices can tell the camera to record or not, based on your personal preferences. The biggest appeal with these systems comes from using a single app to control all of the smart home devices. WarrantyIt is common among consumer electronics to find a one year warranty. Longer warranties give you more time to replace the unit if it stops working due to a manufacturing defect. The longest warranty we saw, found on both the Nest Cam and the Belkin NetCam HD+, is two years.

It is only 3Mb/s down I don’t know the upload but I do have WiFi. I would like 2 3 outdoor cameras that I can remotely view. Using a system that records and uploads to the cloud 24/7 is not possible because it would use 100% or more of my bandwidth. What options do I have that won’t totally break the bank that will allow 2 3 outdoor cameras that store locally to a NVR or desktop computer that will allow me to bring up at least 24hrs of past video recordings when at the NVR or desktop at home and allow me to occasionally view live video through an app on my cell. Hi Joe, to allow 2 3 outdoor cameras to store locally to a NVR without eating up you bandwidth, you have two best options available.
