There are a lot of good reasons to invest in a security camera system for the home. One of the most profound is probably the fact that a good system will provide you with tremendous peace of mind that criminals might think twice before making an attempt on your home. Some of the most damaging crimes executed by professionals require a certain degree of scouted information ahead of time. For the career criminal embarking on a premeditated act of larceny, they'll
want to know what they're getting into. In short, they're li
able to case the joint. And if they see evidence of any kind of security system in place, they very well may choose another target. In today’s parenting environment, security cameras have taken on a new role. This is especially true since so many wireless security cameras provide you with live feeds that you can access from any computer, smartphone, or tablet you have at your disposal. Instead of just keeping an eye out for criminal activity, a good security camera system will allow you to keep an eye on the homestead and, perhaps more importantly, on its occupants while you're away. If you work a 9 to 5, for example, but your kids get home from school at around 3, you'll be able to check in to make sure they got home safe, and to give them a ring on their cell phone if you don't see them home by a certain time. Choosing the right wireless security camera system for your home may hinge on one particular feature that you don't think you could live without.

The ionization sensors are used to detect the small particles from fast burning fires, but because of their nature, they’re more prone to false alarms these type of sensors are usually found built into older smoke detectors. The photoelectric sensors can detect larger particles, so it is a lot more useful for smouldering fires those which have not yet erupted into flames, so they’re better for an early detection and are less likely to trigger false alarms. 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.

For example, here are some situations in which having a video doorbell installed would really come in handy:When you’re expecting a package. You can let the delivery person know to leave the package. And, because you know when it’s delivered and can bring it inside, this helps to keep it from getting stolen. When your young children are near the front door when it rings, but you don’t
want them opening it until you know who is on the other side. When you’re doing something elsewhere in the house, garage, or backyard. When you’re in the shower. You could easily hop out if it’s an emergency, of course, but what if it’s just a ring and go package delivery?When you’re not expecting guests. When you are expecting guests. When you’re not home and/or out of town. You can check who is at your door for safety purposes and maybe even talk with them. When you’re working or making dinner and want to avoid solicitors, you can check to see if the person ringing the doorbell is worth taking the time out of your lengthy To Do list to greet at the door.
