Common Types Of Motion Detector Security Camera

By Rainard Vortigernce


One common kind of motion detector security camera which is also known as nanny cam has become popular today mainly because it is really useful in getting nannies in the act of abusing children. The whole idea behind using a security system like this is to first of all put the camera aid transmitter in a place from where it can observe the surroundings without anyone being wise about its location and then keep tabs on what is happening to your children while the nanny takes care of them.

Protect Expensive Possessions

In today's world where one is given to own pricey things, particularly those that are status symbol items, there is an even more urgent need to give protection to these belongings and one of the options open to you in this regard is utilizing a motion detector security camera. Actually, most modern security systems already have the capability of being able to detect motion and therefore improve the effectiveness of such systems.

With a motion detector security camera, you can catch motion and do so it uses a software application that makes it send signals to the security camera when motion is detected and the security camera then records the events as they happen. These kinds of security systems can employ various technologies to perform its tasks such as infra-red, ultrasonic as well as microwave and even dual technology motion detection.

If you use the infrared motion detector security camera would sense the infrared radiation which humans produce and whenever such radiations disturb the motion detector security camera's own infrared spectrum, the camera starts to monitor the events. In the case of an ultrasonic motion detector security camera, the sensor provides the security camera with signals in the type of ultrasonic pulses which help set the camera rolling. Nevertheless, these kinds of motion detector security cameras cannot work effectively other than in clear surroundings and in case of obstacles, the ultrasound signals are distorted and therefore, functionality of the system is affected.

The microwave motion detector security camera operates through letting off microwaves. When such waves encounter an object the waves get bounced back which in turn helps make an image, and though this kind of motion detector security camera is better than the ultrasonic one, it can still suffer from producing false alarms because of capturing minor movements that in fact don't warrant any kind of alarm being set off.

Lastly, the dual technology motion detector security camera is one that works on a bit of infrared and also a bit of microwave motion technology. In fact, this type of motion detector security camera is going to be the most popular of all motion detecting security systems in the times to come and might well replace the other types of motion detecting security systems being used these days.
