CCTV is now often encountered in every public areas such as malls, campuses, offices, shopping centers and others. The benefits of CCTV themselves will feel useful as a tool for security, where every activity that happens we can monitor live anytime and from anywhere, can also be utilized to record the incident as evidence in future. Maybe you are a business owner who is often lost, for example, may lose a motorcycle, or home robbed but you do not have proof.

WIRELESS SYSTEMS
Wireless camera detector motion security system that can provide total security videos for each place of residence or business. This system makes installation a win and in addition to preserving the system' s resources. In addition, this system is very versatile, especially when using an optional feature.

Generally, brain or heart of a video security system is the Digital Video Recorder or DVR. DVR is typically contain computer processors specifically designed to perform the tasks necessary to create and store digital video files and coordinate and control the functions of a digital video camera. For the motion detector system wireless security camera DVR only one is needed, although it is possible to create a camera system using a variety of camera DVR with a lower capacity inputs ( such as two 8-camera DVR) .

Because the camera system is " wired" security must have a transmission coaxial video cable runs from each camera to the DVR is the only factor determining the number of cameras used in the system is the number of video inputs that can be handled by the DVR ( Usually systems that require maximum 16 video inputs more than 16 usually use more than one DVR ..)

However, the single most determining factor for motion detector security camera system is how the wireless signals cameras' video is handled. Each camera must have a unique frequency or channel that can transmit digital video signals. It is important to pause here for a minute to discuss the use of " channels" as there is some ambiguity involved with the use of the term in the field of video security.

Most of us might be thinking as a specific frequency channel, such as television channel or radio station channel, which is one way of terms used in the industry. For example, wireless cameras may transmit on 921.103102 MHz, for the sake of this discussion, we will call the channel 1 or 921.205012 that we call channel 2. That' s one definition security camera industry to " channel."

However, often times the " channel" is used to reference the number of video and / or audio input DVR or receiver can be utilized. In this case DVR 9 channels will be able to accept input from up to 9 different video cameras are also called " channels." For example the most common DVR units is four, eight, and sixteen channels.

Getting back to our discussion about 16 wireless motion detector security camera system, this system will usually require channel 16 ( camera input) DVR. They will also need a wireless camera 16 each on a different channel ( frequency) . A key factor for these systems will become:
1. Getting the 16 cameras each transmit on different frequencies, and,
2. Determining how to receive the signal.

This can be done in various ways ranging from using multiples of the total output of a video receiver to a DVR from a total of 16 video channels individually, or using multiples of a total of 16 channel DVR video inputs with individual or each camera input using a different frequency ( also referred to as channels) . In addition, modern technological advances have produced an IP or Internet Protocol camera ready that contain their own web server technology. Sixteen of these cameras can theoretically be used to create a system of 16 cameras wireless security motion detectors as well.

In this system, each camera has a built-in sensor is PIR or Passive Infrared. This sensor can detect changes in infrared transmission, such as those caused by moving objects. PIR sensors are usually connected to a relay that switches the transmission of a video camera when motion is detected. The camera stops recording either after a predetermined time period programmed or when it detects motion stops.

A motion detector camera operated several offers potential advantages include:
• Conservation of DVR disk space since the video is only transmitted when motion is detected;
• Conservation of power usage is especially important if the camera operates with battery power source, and,
• A reminder function because the camera only records when motion is detected ( for example, some IP camera or DVR ready to send an email when a camera has been triggered " on." )

In addition, the system of 16 cameras wireless security motion detectors can be purchased with optional features like day / night, Pan-Tilt-Zoom ( PTZ) , object tracking and many other options, which all contribute to making this system one of the most versatile security solution video cameras available today
