Home Security Motion Detectors

In the home security area, motion detectors are a common and popular means of securing the house and yard. The motion detector can be connected to an alarm or a light, both of which alert the owners that there is possible danger of an intruder.
The motion detector is a security device that uses either an electronic or mechanical sensor to measure movement to detect unauthorized entry. There are 3 main types of sensors used in motion detectors:
- Microwave - this sensor sends microwaves pulses to measure the moving object.
- Ultrasonic - this sends electrical pulses to measure the moving object.
- PIR (Passive Infrared) - measures body heat, but emits no energy.
Modern motion detectors often use a combination of technologies. This tends to make the detector more accurate and reliable, and cuts down on the number of false alarms. One of the major causes of false alarms is animals – when a pet moves in front of the sensor, it is detected as a moving object and the alarm sounds. Many newer models have a “pet-sensitive” function that ignores body mass below a particular weight.
Mechanical Motion Detectors
One of the simplest forms of mechanical motion detection is the tripwire. If a bell or something similar is attached to the wire, it will sound if the wire is knocked or “tripped”. This type of device is easily disarmed, however, by cutting the wire. This makes the device only effective if it can be concealed from view.
Electronic Motion Detectors
The major ways that motion is electronically detected are optical and acoustical. The motion detector can be connected to an alarm, a light or a security camera, or any combination of the three. When movement activates the sensor, the attached security device is activated.
Motion detectors that are employed to provide security for the home are most often connected to a bright light. This serves a dual purpose – it illuminates an intruder, and probably scares them away, but it also provides light for family members returning home after dark. This prevents falls and reduces the possibility of attack from a prowler hiding nearby.

The Reality TV Show Big Brother has become a huge hit these past few years - it has come up with 10 seasons already since its inception in 2000, and an 11th season is already on the works to air in 2009. Part of the appeal of Big Brother comes from the fact that the contestants, more commonly known as house guests, live in a house that is surrounded by cameras and microphones that are left on – 24/7 for the next three months.
Having cameras and monitors inside your home is not exactly something new, and it is not something trivial either. Putting security cameras and monitors inside your houses has been an accepted practice for many years now. But in real life, you do not just put cameras and security monitors to spy on your family members or roommates, you put them there, most importantly, for your security.
Home security monitors have become so popular that they now have different kinds. You can make use of Cathode Ray Tube monitors, Liquid Crystal Display monitors and even hand-held monitors. You can also use your computer monitors and TV screen to hook up with your security cameras. Another good thing is that most remote security systems nowadays are available with their own monitors. This way, you do not have to shop for another monitor; consequently, you will be saving more money. This is perfect if you just need one camera, say to monitor your kids or to check if the nanny really does her job. You can also use this if you just want to check out if your husband is having an affair or is your roommate stealing things from you. But, if you plan on making sure that your whole house is under surveillance to keep it from burglars or criminals, then it is for the best that you get multiple cameras and monitors.
There are thousands of stores and online markets where you get home security monitors. You have a wide array of products to choose from. They vary in size, price, and capabilities. You can get a 2.4 GHz camera for as low as $74.25. The receiver of this camera can even hook up four cameras all at the same time. Cameras on disguise are also very popular nowadays. People may be unsuspecting that a teddy bear that costs $279.89 has a high-quality camera in it already. A tote bag that sells for $189.89 and has a 2.4 GHz camera in it may also surprise other people.
It is really up to you on what you want or what you think will suit your house and your lifestyle. You have to consider your budget, but at the same time you should also not compromise the quality to your money at hand. After all, it is your and your family’s security we are talking about here. You will have to make sure that you get the monitors that have high resolution. You might miss out on something or you might find things blurry if you get the low-resolution ones just because you are being thrifty and all.
