Types Of Motion Sensor Camera Systems And How They Work
If you want to keep your home and family safe at all times, you should consider installing a motion sensor camera for security purposes. There are several types of security devices that can detect movement. Each one has its own specific functions, pros, and cons. Some types of cameras may be more suitable for conditions surrounding your home and its occupants. Review the various kinds of motion devices before deciding on one system.
Motion security cameras actually work in an uncomplicated manner. Most models will have a sensor that detect physical disturbances in the area surrounding your house. Covered areas could include the garage, driveway, backyard, front garden, and some parts of the street in front of your home. Some people include the interiors of their homes in the coverage for more security such as the kitchen, front foyer, living room, hallway, or stairway.
When motion is detected by the system, the motion sensor camera sends a signal to the main unit which can set off an alarm to inform the homeowner or security team of an intruder. The alarm can be either noisy or silent. When the security system identifies movement, it also lets the camera focus and follow the movement. A video image will be sent to a monitor inside the home or to another location via the internet.
Lights may flicker depending on the type of system. The cameras around the house can reveal black & white images, colored, infrared, or night vision pictures. Infrared cameras are one of the most popular security devices and are sometimes called heat vision devices because it detects body heat and motion. Once there is a change in temperature in the area, the sensors are activated and focus on the unusual heat source.
Another type of motion security system runs on microwave motion detection. This type of camera sends out microwave signals that bounce back when it hits something that moves. The microwaves that bounce back will create an image of the moving intruder that can be viewed on a monitor. Once the sensors are activated, the system will record the moving object. Some expensive systems use both microwave and infrared sensors.
While most security cams are wired or attached by cables to the main unit, a monitor or computer; there are also wireless devices that can detect movement such as the Peak models. They can be short range or long range wireless cameras. Wireless systems can transmit signals from 300 feet to 5 miles. Of course, if you are just securing a home, a 300 foot wireless system will provide sufficient coverage.
For those with house pets, consider setting up a pet-immune motion detecting system. This security device lets your dogs and other animals roam freely without setting off the alarm. The sensors will be triggered if it detects objects larger than typical pet sizes or something as large as a human profile. This system also uses passive infra red technology or PIR. It can differentiate human and non-human body temperature.
Spy detectors can record videos unnoticed by intruders. This type of security unit can merge into a background or into your house exterior or interior without being seen. Some of these types of cameras are as small as golf balls and can be designed to blend-in with other things in the surroundings. Many of the spy detectors run on PIR technology and operate during the day or night.
Ultrasonic detectors are also common types of security devices. This type of camera system will emit sound waves just the way bats find their way around. Bats are blind and rely on sound waves to avoid colliding with objects or other animals. A unit that uses ultrasonic sound waves can form an image from sound waves that bounce back from moving objects. The sound waves are not audible to the human ear.
The best benefit of having a motion sensor camera is being forewarned of intruders on your property. Once an audible alarm is set off, the sound may drive away any burglars without the need of a confrontation. Your family and possessions will be safeguarded against theft and harm. Some of these security systems provide light as you approach your home so you can see your way to your doorstep in safety. You can buy these products at affordable prices online. The cheapest units start from $48 and the most sophisticated brands cost up to $400.
