Surveillance security systems are becoming much more common and affordable to the general public. Video and electronic technology have come of age to give heightened performance and to make it easier to protect homes and business alike. Wireless cameras are now guarding on the outside of the house and keeping an eye on the baby inside the house.
What Makes a Wireless Surveillance Camera?
Simply put, the camera has no wires connecting it to the receiving device. There is a transmitter built into the camera which sends the video data to the receiving device, be it a computer monitor via a PC, a VCR, or some other recording media. One benefit is that there are no wires for a burglar to deactivate.
The traditional looking surveillance cameras are still around but more complex and realistic looking models have been engineered to fool the thief. These models are very clever in that they are camouflaged.
Depending on the surroundings they are installed in, they can resemble air purifiers, boom boxes, clock radios, lamps, or ball point pens. They can be had to transmit either color or black and white images.
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.
Recording What the Camera Transmits
As stated above, the signal can be received on various devices. The image quality and the recording duration of the receiving device depends on the need. For example, with a VCR loaded with a T-200 tape, the device may record for up to 10 hours. Specialized long play tape recorders can be found that hold 960 hours on each tape.
The DVR (Digital Video Recorder) is not just for recording TV shows anymore. One of the benefits of recording wireless camera transmissions on a DVR is that all data is stored digitally on a hard drive. This ensures that the quality of the captured data will not degrade, as it will with a VCR tape.
Continuous Wireless Transmissions
Using a 960 GB hard drive, at one end, shooting 30 frames per second will save an amazing 3840 hours of video! On the other hand, if you want the best action with the accompanying sacrifice of recording time, shooting at 480 frames per second will allow for a mere 240 hours. It all depends on the situation.
Nighttime Surveillance Situations
Not all crimes or intrusions take place during the day. During darkness a night vision wireless surveillance camera is the answer. Some of these cameras are multi-purpose; they transmit color video during the daytime and black and white at nighttime or the lights are off. Both cases are covered 24/7.
Some wireless surveillance cameras use the infrared spectrum to capture video in low lighting conditions. This kind of device is especially well suited to a closed circuit television security system. The advent and coupling of new technologies make it clear that there is something out there for ever security need at a reasonable cost. And it is easy to find a specialist consultant to design a system according to needs.
