Wireless camera with or without a digital video recorder (DVR) is an integral part of a large home / office security system. Even when used as a stand-alone wireless camera itself as a serious deterrent to thieves and criminals. In addition to reasons of security cameras for wireless tracking and monitoring activities are used.
Why wireless?
Wireless Internet Camera Surveillance
In recent yearsCameras> Wireless is becoming increasingly popular. Traditionally, wired cameras in use (very limited). This was partly due to the high price of wired cameras, and partly because of the need for wires from camera to photo / video recorder and / or monitor.
With the advent of new technologies and cheaper in video processing and memory expansion has become much more feasible, low-budget wireless cameraHome and office monitoring.
Of course, advances in technology and price is scaled for wired cameras as well, but the use of low-cost wireless technology offers an advantage over wired devices to wireless cameras, because the costs for copper wire and runs from point A will eliminated after B. In addition, the wires are an easy target and can be attacked if it is visible. The wires can also to the recording device, which is under active attack or aManipulation. These questions are provided by wireless cameras, wireless are taking the video signal, and the recording device can be hidden, or even not present in the same premises.
Similar to wired cameras, wireless cameras distort the frequency at which the camera works to manipulate. However, you can set up a system that operates on two different frequencies, so that if a frequencydistorted or blocked, keeping the rate of transmission of other images / video signals.
Wireless cameras are easy to install and easy to replace, if necessary, since the lack of wiring.
The composition
Ideally, you should use the following components for the creation of a wireless camera.
1 Wireless Camera
Should be used a wireless camera, CCDThe technology expands, images / video in color and has a resolution of about 500 (H) * 500 (V) pixels or more. It 'very important that the camera should provide night vision devices. Infrared LEDs allow the camera to see in the dark. Look for a minimum of 20 infrared LEDs, and more than 10 meters night vision.
If the wireless camera mounted outside the camera housing is robust and stable enough to withstand the sun,rain, strong winds and tempering.
It 'should choose a camera with a very low lux rating. An evaluation of low lux camera can be built to have a clear picture even in low light conditions.
Be aware that, although the signal lines are absent, you may still want the power to provide the camera with power supply. Alternatively (if possible), uses the camera's batteries fully portable and completely wireless.
2Receiver
Receiver is the component of the system image or video signals (wireless) receives and converts these signals into a format suitable for display (or TV) input. If this appliance has a memory image or video, the device is called DVR (Digital Video Recorder). In general, you should at least support your DVR IGB memory. Receiver (or DVR) can be more than one channel. This means that it should be possible (in theory) use many wireless camerasso many channels available. Technically, this is not possible, however, some of the channels can be overloaded with noise, or signals from other nearby wireless devices.

In most cases it should be possible to use your home TV to view photos or video. The receiver (or DVR) to connect to your TV via cable. The TV does not connect to the DVR all the time. If there is a simpleRecipient You can send photos or video monitor in real time only. And 'possible to monitor small screen dedicated battery powered, largely receiver (or DVR)-Unit includes items as well. If you want to use the computer monitor for display purposes, we will ensure that the signal receiver or DVR-generated compatible with PC monitors.
