Over the past decade there has been a marked evolution in the technology of surveillance equipment, along with a significant reduction in price among security cameras, tracking devices, and GPS units. Perhaps the biggest evolution of these has been seen in the area of hidden spy cameras. In less than 10 years, the “nanny cam” has evolved from a complicated setup of electronic equipment to a simple to use electronic work of art. So, what steps has technology taken in the evolution of spy cameras?
Wired to Wireless Hidden Cameras
Like standard security cameras found today protecting homes, businesses, and found on nearly every street corner in the city, nanny cams were another wired camera needing video connections running from the camera unit back to a recording device, like a VCR or monitor. Along the way, micro chips got smaller and more powerful in creating miniature lenses, or what is today called pinhole cameras. These were easily placed into such everyday items, like teddy bears, clock radios, and nearly any household item. Although still available today and often seen in disguised hidden cameras, like smoke detectors, floodlights, and some wall clocks, they require two sets of wires to transmit power and signal to a TV or DVR.
Concealing the wires was a bit cumbersome, but then a new generation of wireless cameras hit the market starting around 2000. First manufactured in such inanimate objects as planters, teddy bears, books, exit signs, and countless other items, wireless cameras eventually found their way into practical working components, like alarm clocks, clock radios, wristwatches, cell phones, fountain pens, and CD players. Inside the component was a tiny pinhole video camera and a small wireless transmitter. When a customer purchased a wireless nanny cam, they got not only a working electronic device but a receiver, A/V cables and power adapter as well. The tricky part came when it was actually time to set up the hidden camera system. The receiver that was provided had to plug into either a monitor close by or a VCR if they wanted to record events throughout the day. This required the user to place the VCR somewhere in the house within 100 feet of the camera, either in another room or on another floor altogether. The receiver was then plugged into the VCR, and when the user was ready to start recording he just hit the “start” button. Voila!....well, not exactly. A standard VHS cassette can only record eight to ten hours max, which can create a problem. However, with the advent of PCs and DVR players this did greatly extend the recording time available.
Let's say a mother wants to keep an eye on the nanny or babysitter while she's at work during the day. Just before leaving the house in the morning she would plug in the nanny cam and turn on the VCR or DVR to start recording. On arriving home at the end of the day and wanting to review what was recorded, she would have to sit for several minutes while fast-forwarding through hours of video, often looking at nothing at all. At the time, this was the only means available to monitor her child's welfare during the day, and the process at best was tedious.
Motion Activated Spy Cams
The concept of motion activation in video recording was a big breakthrough in the spy camera industry. Although the technology had been around for years, it wasn't until the mid 2000's that it became available and affordable to every day consumers. No longer did people have to sit through countless hours of viewing blank tape only to find nothing eventful was captured that day. Now, with motion activated hidden cameras, recording only took place when the camera's sensors detected activity in the room. If nothing moved, then the camera sat idle. As a result, the user might only have to watch 30 minutes to an hour of tape rather than 8 hours or more of static recording.
Another technology feature that came along to compliment the motion activated features of hidden cameras was the increasing popularity of the DVR, which eventually all but replaced the VCR. With a DVR there was no longer a need for VHS tape, since everything that was recorded now was done digitally, frame by frame. The advent of motion activation together with the convenience of the DVR made spy camera and nanny cam users very happy. Then, when it didn't seem things could improve any further, technology came along once again to improve the spy camera one more time.
Built-in DVRs and Micro SD Cards
A growing need started to develop for a self-contained, all-in-one hidden camera system, which by 2006 saw a solution finally arrive. To the delight of everyone, the motion activated spy cam now came with a built-in DVR, which utilized a micro SD card for hours of additional recording time and expanded memory. Gone, were audio/video cables, wireless transmitters, receivers, VCRs and obsolete cassette tape. The new generation of nanny cams and spy cameras allowed the user to set the device and walk away; either for the day, or weeks at a time. When he returned and wanted to view what the camera had recorded, he simply removed the SD card and inserted it into a USB card reader or directly into an SD card slot on the computer. Since the camera only recorded when movement was detected, viewing what had been captured became quick and easy. These cameras, which can be built into any everyday item imaginable, and often include added features like variable recording speeds, low light apertures, still shots, and date and time stamps, remain as the most popular hidden spy camera dvr on the market today. It didn't seem that video surveillance could get any better or easier, but then technology advanced once again to bring us the latest generation of hidden spy cameras.
Real Time Remote Viewing
Just when you thought covert spy cameras couldn't get any better, the newest technology that's come out now allows live, remote viewing capabilities. With this new platform of video surveillance, your desktop PC or laptop now becomes a server and a DVR.
The way it works is, the user places the spy camera in any room of his home, office, or other location he wishes to monitor, and the video is streamed live to his computer. As an example, say a guy owns a manufacturing firm in city “A” but has to travel to city “B” frequently to meet with suppliers. He wants to keep an eye on his business and workers while he's away, so he installs a few live, wireless remote-view cameras around the premises. Now, from wherever he is, here and abroad where he can establish an Internet connection, he can log into his laptop and remotely watch live what is taking place at his business in real time. He can also record directly onto his hard drive what the camera is capturing simultaneously 24-hours a day. All that is required is to load the included software program and to connect the receiver directly into the USB port of the computer located on the premises.
This technology is also great for mothers who work and want to monitor their child and babysitter during the day while at the office, or for parents of teenagers who are left at home unsupervised, or perhaps for a husband or wife who may suspect the other of cheating and infidelity, or for family members who are responsible for the care and well-being of elderly parents or relatives who are residing in nursing homes and long-term care facilities. The uses and applications for remote live viewing spy cameras are virtually unlimited.
Next on the Horizon?
It seems that every time we think technology can't improve over what we have today, we are continually surprised in the next technological advance. This is especially true when it comes to wireless hidden spy cameras. We are always excited and eager when the next new spy device or camera is introduced to the market. When that happens, you can be sure The Covert Eye will be there to offer the latest and newest covert surveillance product to our customers.
