There are various ways to fit these 5 components together, but the ending result will ultimately give you a complete security system.
How does a Wireless Surveillance System Function?
To start off, your Wireless cameras will use the built in transmitter to send the captured footage as a signal to your receiver which is generally connected to your VCR or DVR.
Your camera's built in transmitter primary function is to relay the video signals to the receiver. The receiving unit generally connects to the viewing or recording device for further processing. The transmitted signal can be simply viewed by the user or recorded and saved for future reference.
Several Kinds of Wireless Cameras
To start with, Dome Cameras are basically board cameras that are built into a dome covering. Dome Cameras are usually equipped with high power Infrared leeds primarily for indoor and outdoor use as well as low light settings. These cameras have a special feature known as the day/night mode. This feature makes the camera record in color during the day light while in low light conditions it records in black and white. The camera senses the amount of light available in the area and automatically switches to that appropriate mode with out the users intervention.
Moving on, Professional cameras can be affixed indoors and outdoors on buildings, ceiling brackets, and walls. Not to forget that many professional security cameras are waterproof and weatherproof, can function in low light conditions day or night, and can fit in very tiny or hard to get to areas via a snake camera. Professional security cameras are generally very high in resolution, they usually deliver very sharp and clear images with prominent detail. You can find them with color or black and white images.
Another type of cameras is hidden cameras. These types of cameras are very tiny to the extent that you can not easily distinguish them with your bare eyes. You can find these cameras hidden in many relevant household items such as shirt buttons, teddy bears, smoke detectors, pens, radios, clocks, and baby wipes.
Understanding Transmitters
Wireless Cameras generally use 2.4GHz transmitter, this usually transmits video and audio footage over a distance ranging from 200' to 700' depending on the condition of the outside weather. However there are many more advance and powerful Wireless cameras on the market today. But you will definitely find a Wireless camera with a transmitter built in it since most Wireless cameras do come with this feature.
Understanding Receivers
The main job of the receive is to catch the signal of the audio and video footage sent by the transmitter in the Wireless camera and then send this signal to the VCR or DVR that connects to it for further processing.
Understanding Recorders
As you know, VCRs record the audio and visual information to a video cassette tape which will eventually be filled up after 9 hrs or so, and then it has to be replaced. Fortunately, a very helpful feature have been added to security based VCRs. These newly released VCRs come with time lapse and security motion detection settings which enables the VCR to initiate the recording process merely when any type of motion or movement is detected. The Time lapse technology is basically a series of photos taken in order and over a set number of time intervals. Obviously, not every frame is recorded like real time footage. Both technologies, Motion detection and Time Lapse, greatly assist in minimizing the space usage on your videotapes.
Since the cameras operate only when motion is detected, a 9 hour video tape could last for weeks before it is filled up. The way it operates is simple, the cameras starts to record when it senses any type of movement in its view range, after 30 sec or so of inactivity it seizes recording, then it resets and continues to monitor for the next motion.
Understanding Digital Video Recorder (DVR)

DVRs on the other hand, don’t use video tapes at all. A DVR records video and audio footage directly to the hard drive of your computer or to other media types such CDs and DVDs. This makes it easy for you to share the information by simply burning a DVD or CD of the footage incase you need to share it with the authorities. Adding on, this method of digital storage is convenient on several levels since it will save you storage space that might have been taken up by bulky video tapes. Not to forget that you will obtain a high quality result all the time since digital media usually has a better quality image than VCR tapes. A tremendous benefit to DVRs is that once you install them in your house or business you can practically view them from anywhere in the world using the internet.
