With these cameras, you can be sure that there is no question of wires as their primary source of
powering up is from the batteries. So, all you need to have to make them work are the batteries that need to be charged properly from time to time which will set you for unending video feeds day in and day out. This also means that they do not need any electrical power outlet within its vicinity which can only be good news. Hence, your days of getting tangled between wires are over thanks to the
battery operated security camera. One of the biggest advantages of getting security cameras is that you will be able to keep an eye on the entire house. This is why you always need to make sure that the cameras are placed strategically so that this objective is achieved.

The First Alert P1010 uses the aforementioned technology, so it has a beam of light inside a small chamber which does not directly hit the photoelectric sensor, but, the moment smoke particles enter the device through the holes in the metallic section, the light gets diverted and it will immediately hit the sensor, thus sounding the alarm. In case a fire is detected, you will be able to hear three beeps, pause, three beeps, pause and repeat, while the LED light will flash rapidly – the LED is located inside the Silence / Test button the horn is loud,
reaching up to 85 db, 10 feet away from the device – if you have a hearing impairment, it is advisable to have a look at smoke alarms with built in strobes. 1. Which type of sensors are equipped on the smoke detectors?Smoke detectors can have two types of sensors: ionization sensors, photoelectric sensors or both usually called dual sensors. The ionization sensor is used to sense flashing fires by detecting the small particles generated by these fast burning fires and triggering the alarm. The technology behind it involves using a radioactive isotope of americium usually, it’s Americium 241 to ionize the air inside a chamber and, if the sensor detects any changes in the air, it triggers the alarm. The disadvantage of using such type of detectors is
that they are more prone to false alarms such as when you’re cooking or when there’s a large amount of steam. The photoelectric sensor is more sensitive to larger particles which are specific to slow burning, smouldering fires which could originate from a forgotten cigarette on the couch, but the sensor is not as sensitive to flaming fires. The way this type of detector works is that it uses a light source can be infrared, ultraviolet or visible which points away from the sensor, but, in the event of smoke entering the small chamber, the light particles will be scattered, therefore, some will hit the sensor and trigger the alarm. This type of technology is used a bit different in larger spaces, where the light beam is directed towards the sensor, but if the intensity of the light drops under a certain level due to smoke, the alarm will be triggered. 2.

Some may trigger when the door or window vibrates versus actually opening. A carbon monoxide detector
triggers when the level of carbon monoxide in your home reaches a dangerous level.
Unlike other environmental dangers, you cannot see, taste, or smell carbon monoxide. These detectors can save your life and those of your pets. Carbon monoxide is released when you burn gasoline, wood, oil, charcoal, propane, and natural gas, so homes with gas appliances, chimneys, wood burning stoves, and connected garages have a higher need for carbon monoxide detectors. Like smoke and fire alarms, these sensors can work as stand alone alarms or connect with your security system. It’s always a great idea to connect detectors to your system so that a monitoring center can notify you and emergency dispatch in case the alarm is triggered. Some wireless home security systems offer a video recording storage option and others don’t. For the ones that don’t, you are able to see a live video feed of your home any time you access your system; however, nothing is recorded. The systems with video storage generally include either a local storage or cloud storage option. A local storage option saves a pre determined number of video clips on the device itself.
