Video surveillance security cameras are are becoming more and more a part of our daily lives. The technology and computer applications are changing and progressing at an alarming rate. These cameras have the ability to lower crime at the home and to assist in keeping terrorism in check.
Types of Video Surveillance Cameras
Dependant on the situation, there are a broad range of surveillance security cameras available to meet the needs. No longer are consumers restricted to the traditional and obvious looking camera. There are two methods which can be used for the video camera to communicate with the receiving device – wired or wireless. Many times a wired connection is cost prohibitive to install or its presence would give away the location of the camera and compromise its effectiveness.
If the lack of a wire is not enough to render the security camera “invisible”, many video cameras are being manufactured to be concealed inside other devices. The world of James Bond has arrived!
For example, how about concealment in a functioning boom boxes? Or inside a clock radio? How about a ball point pen laid casually on the desk? If it makes a difference in the application the cameras can transmit in either color or/and black and white.
And these security cameras can get the job done. One wireless camera built into a cassette radio found at www.extremesurveillance.com has an effective line sight of seven hundred feet and 380 lines of resolution. It comes loaded with a 2.4 Ghz transmitter that delivers to a VCR, radio, or personal computer.
Surveillance Camera Recording Devices
Sometimes the time between changing the recording media is an important consideration. Again, choices abound. For example, using a VCR recorder and the appropriate tape, the received data can record can run continuously for up to 10 hours.
The Digital Video Recorder (DVR) has been zooming off in popularity over the past five or so years. Since the data is stored on a hard drive, like in your PC, and hard drive capacity has increased exponentially, the DVR is the storage device of choice if massive data storage is a concern.
Imagine, with a 960 GB hard drive installed, capturing 30 frames per second will save an archive 3840 hours of video. On the other end of the spectrum, to capture tight knit action with diminished recording time, the camera transmitting at 480 frames per second will still take 240 hours to fill the drive. Requirements drive the decision but having such flexibility is wonderful.
Low Light Cameras
Sometimes even when the outdoor area is well lighted, shadowy areas exist and that compromises security. The obvious answer is to employ a night vision surveillance camera. Some video cameras have multiple capabilities: they can take color video during the day and deliver to black and white when in periods of darkness. One camera covering all the bases.
Infrared surveillance cameras use that spectrum when transmitting video in poor light conditions. A camera using this technology is well suited for a closed circuit television security system. For home applications it makes good sense to mount these kinds of cameras outdoors and other cameras in other places as appropriate.
One example is a camera in the baby’s room to keep an eye on the little one. Using the proper software the views can be switched on demand from a central PC. With all these options in surveillance camera developments, there is no reason why a homeowner or a business can’t entertain a solid sense of security.
