Motion Detector Security Camera comes in many different size and forms and are used in a variety of ways; but mostly for covert operations in areas where there is suspected criminal activity. An example to this is the nanny cam that has become very popular today mainly because it is very helpful in catching employees in the act. The whole idea behind using a security system such as this,is to place the camera in a position that is hidden but will only record if there is activity or motion. With modern IP technology remote viewing and recording can be standard features.
Asset Protection
In today’s world it has become increasingly urgent to put measures in place to protect ones assets and to monitor the activities of employees in sensitive and remote areas or areas where there is no visual supervision. The Motion Detector Security Camera can be the ideal piece of equipment for the job as it is a unit that is triggered by activity and will only stay on with activity present. This is especially useful if you are recording the event to view at a later date as data space will not be used until there is motion. It will also alert you if some one enters a restricted or sensitive area.
With a Motion Detector Security Camera you are able to detect and record motion by way of software application and a DVR (Digital Video Recorder), which is activated by a signal from the security camera or motion sensing device on the camera. The sensing of motion triggers the DVR which then records the events as they take place. Such security systems can use different technologies to perform this task, they include infra-red, ultrasonic as well as microwave and even dual technology motion detection.
If you use the infrared Motion Detector Security Camera the detector would sense the infrared radiation of the area that it is viewing. If a human or animal passes through the area, the detector will see the change in infrared frequency and trigger the camera to begin recording the event.
In the case of an ultrasonic Motion Detector Security Camera, the sensor works by producing ultrasonic pulses that when disturbed, sets the camera rolling. However, such motion detector security cameras are not able to work properly other than in clear surroundings and in case of obstacles, the ultrasound signals are distorted and thus, functionality of the system is hampered.
The microwave Motion Detector Security Camera works by way off a microwave transmitter and when the waves encounter an object, the waves are reflected back to a detector which in turn activates the camera system, and though such a motion detector security camera is better than the ultrasonic one, it can still suffer from false alarms because it will capture minor movements that in fact do not warrant any kind of alarm being set off.
To combat the problem of false alarms, manufactures have introduced the use of the dual technology motion detector security camera. It works on infrared and microwave motion technology, this has reduced the false alarm levels as the detector needs two trigger events to activate the security camera and in fact, this kind of Motion Detector Security Camera will probably be the most popular of all motion detecting security systems in the times to come. And may well replace the other types of motion detecting security systems being used at present.
