The Nest Hello adds a level of security to your home, because it can clearly see and detect motion well beyond your front porch. And if you sign up for video storage, you can access up to five days worth of video to ensure any suspicious activity is captured and saved. When you are looking at the various options on the market, the first thing to look at is the feature set and the compatibility of the doorbell cameras. Make sure that the doorbell camera has all of the features that you would want and/or use. For instance, if you travel a lot, an important feature may be that the camera can send the feed directly to a mobile device. Different brands also offer various camera angles and even zoom features.

For one, the ring video doorbell came up with something that was considered very revolutionary at the time and that is the motion sensor which is really a heat motion sensor. I do like the fact that the heat motion sensor was meant to detect people not video motion and you can change the sensitivity to the heat moron but the Ring doorbell motion sensor does not do that very well. No matter what the sensitivity level that I set it to, it will always pick up large trucks and SUVs driving by on the road in front of my house since my ring doorbell faced the street out in front and the the street is more than a 70 feet from my front door I still picked up garbage trucks and large SUVs that passed by because of their heat signature. I also realized that even though you can change the directions of where it will pick up heat motion it wasn’t quite doing that. This new doorbell camera does a better job because it makes sure that you can draw boxes on the video view of exactly where you you want motion to be detected. So when it came to making sure it only picked up motion at the front door and then the front yard I didn’t have to worry about motion that was happening with cars driving by only when someone actually walked up to the front door or through the pathway to the front door.

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. 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.
