Hidden Nanny Camera

Written By:
Tuesday, September 6th, 2011

So you feel comfortable now that you have a baby monitor camera so you can keep a watchful eye on your infant any time you want to.   But in this day and age, that’s really not quite good enough.  That’s because not only do you need to keep and eye on your baby, but for complete piece of mind, you need to keep and eye on the nanny as well.  The best method for doing that is to install one or more hidden nanny cameras.

There is nothing special about a nanny cam except the name.  Of course they are called nanny cams because the soul object of having them in the first place is to keep a watchful eye on the nanny.  And you can do this covertly or overtly.

Should you choose to watch nanny covertly, it will most likely be best to do it with a hidden nanny camera.  Security Camera King has a huge inventory of hidden cameras-cameras that make great nanny cams.  Whatever camera(s) you choose, they will need to be hooked up to your Digital Video Receiver or DVR or broadcast over the Internet to a Network Video Recorder or NVR.  Should an inappropriate act occur, you will have it recorded for future use as evidence.

You could purchase an IP (Internet Protocol) ready camera.  This would allow you to monitor the camera via the Internet while you’re at work.  Just a quick click to access an Internet browser and you can see what the camera is seeing in real time (live).

However, there’s an even better method thanks to Security Camera King’s DVR design.   Mount the hidden cameras in the room(s) that you think are best to monitor.  Connect the cameras to your DVR.  Connect your DVR to the Internet and you can view ALL or your cameras.  That’s because each one of Security Camera King’s DVRs is IP ready themselves and include their own web server technology.

Do you have an employer that won’t let you use your work computer for personal use (like viewing the hidden nanny cameras)?  That’s no problem with Security Camera King’s systems because anywhere you can pick up broadband Internet you can also monitor your cameras and that includes using your 3G or 4G smartphone!

Security Camera King has a wealth of hidden cameras.  Although not every type of hidden camera can make a good hidden nanny camera.  The following list is some of the hidden cameras that Security Camera King sells that would make good hidden nanny cameras:

  • 420 TVL Motion Detector – this works especially well if you already have a burglar alarm installed.  This unit looks like a stand motion detector but in reality is a 420 TVL hidden camera
  • 420 TVL Smoke Detector – the smoke detector isn’t functional but the camera is!
  • 420 TVL Pinhole Security Camera – You can hide this just about anywhere
  • 400 TVL wired Phillip’s head screw
  • Desktop Speakers – they look like typical personal computer speakers
  • Wall Clock – almost impossible to detect the camera
  • Alarm Clock – This works well anywhere but is especially suited for use in bedrooms or babies’ nursery.
  • Wall Clock with Humidity and Temperature readings – Looks great, all of the clock functions work, and like the wall clock mentioned above it’s almost impossible to detect the camera
  • Cordless House Phone – The phone works and so does the camera, hidden in the base unit
  • Suspended Animation Clock – The clock is quite the novelty item. The camera hidden inside is quite the hidden nanny camera
  • CD/Boombox – Nanny can listen to some music and have her picture taken at the same time
  • Heater Thermostat – looks like a typical heating/cooling control
  • CD Clock Radio – Like the alarm clock above this is especially well suited for bedrooms and even the nursery.

There are several more hidden or disguised cameras that do the job, but listing these at least gives you a good idea of what kind of hidden camera makes a good hidden nanny camera.  If you have additional questions on hidden nanny cameras check our catalog pages for hidden cameras (http://www.securitycameraking.com/wireless-hidden-cameras-253-ctg.html for example) or contact one of our security experts either via Live Chat or telephone at 866-573-8878.

Hidden Camera Equipment

Written By:
Tuesday, September 6th, 2011

Security Camera King has a full selection of hidden camera equipment to satisfy your needs.  Modern technology has resulted in a tremendous variety of disguised and hidden camera equipment.  As a matter of fact, the smallest hidden camera that we offer for sale is the size of a Phillips head screw!

How does hidden camera equipment work?  The following is a brief explanation.

First the camera must have a lens.  The lens’s duty is to gather the light reflected by the objects in its field of view and focus them onto a sensor chip no larger than 1/4 to 1/3 inches square.  Most often but not always, hidden cameras use 3.7 mm wide angle lenses.

The sensor chip is the key factor of a digital camera.  There are two different types of sensor chips and although they both work a little differently, the both produce the same result, electrical impulses that can be measured and used to create a digital video image.

The two sensor types that do this are either the Charged Coupled Device or CCD or the Complementary Metal Oxide Semiconductor or CMOS.  Without at least one of these sensors, the camera just wouldn’t be possible.  You can see that since the lens and sensor chips are so small they can easily be packaged in such a way that no one would suspect the hidden camera.

However, there are some electronic components that are required but these are normally wired in small Integrated Circuit (IC) chips which take up very little space.  One of these chips is an analog to digital converter.  Ironically the signal up to this point has been an analog signal and the analog to digital converter changes it to full binary or digital data.

Once the data has been finalized it is sent to the Digital Video Recorder or DVR.  The DVR differs depending on the type of camera.  Some cameras are hardwired to the DVR via a coaxial video transmission cable and others have their own on-board miniature DVRs that normally save their information to either on-board memory or portable media such as SD cards, Thumb flash drives, and the like.  The latter case allows for complete independence (and makes for great hidden camera equipment) for the camera; in other words it is self-contained and needs no wiring.  These units also usually operate on one-time-use or rechargeable batteries

So, with the above in consideration we can categorize hidden cameras and hidden camera equipment into two different categories.  One where the camera is wired through to a digital video system’s DVR; and standalone (and usually portable) self-contained units.

Security Camera King offers a full line of hidden camera equipment including the two categories mentioned above.  It would be a bit tedious to mention any properties or features of these cameras in the space that we have in this article.  But to make you aware of the vast supply Security Camera King has, we will list the different cameras that are available representing both categories we have previously mentioned.

Digital Recording Device

Written By:
Friday, September 2nd, 2011

A digital (audio) recording device, according to the U. S. Code of Regulations (Title 17, Chapter 10, Subchapter A, paragraph 1001), “is any machine or device of a type commonly distributed to individuals for use by individuals, whether or not included with or as part of some other machine or device, the digital recording function of which is designed or marketed for the primary purpose of, and that is capable of, making a digital audio copied recording for private use…”

Huh?  Let’s try this again.  A digital recording device is any device that records in a digital (binary) format.  There are all kinds of digital recording devices.  Since the technological advancements that have come with the computer age, many other industries have borrowed the same technology but may have modified it slightly to meet their specific needs.

As far as the digital video security and surveillance camera industry goes there are basically two digital recording devices that immediately come to mind.  One is the digital phone/room recorder and the other is the Digital Video Recorder or DVR.

Security Camera King offers two different digital phone/room recorders, product# DPR-N88 and product# DPR-N308.  These two recorders are audio digital recording devices.  They work by recording to a storage medium a stream of discrete numbers that represent the changes in air pressure or sound.  In contrast, analog sound is created from a continuous wave that represents the changes in air pressure or sound.

Basically using a simple set of the numbers 1 and 0 (called binary or digital format) just about anything that is recorded as an analog set can be converted to digital.  There are several advantages to digital recording devices.  First and foremost is that digital recording does not degrade in quality over time like analog recordings do.  Another advantage of digital recordings is that, thanks to the ever increasing technology of the computer industry, more data can be stored digitally than can be done by an analog medium.

While digital audio recording record the changes in sound, digital video stores information that represents the changes over time in chroma and luminence for video.  Once again, the older (analog) method of recording video was, like analog audio, the creation of a continuous wave.

The security camera industry reaped the biggest benefit from the “computer age” when they started using digital recording devices called DVRs (which are also the second type of digital recording device referenced above).  In the security camera industry the main digital recording device is the DVR.  There are several types of DVRs which use several different methods for storage as a digital recording device.

The most common digital recording device for full size commercial or residential security camera systems is the Hard Disk Drive or HDD.  The DVRs HDD is a non-volatile (will not lose recorded information when power is disconnected), random access digital recording device.  Security Camera Kings systems’ HDD storage options ranges from 500 Gigabytes (GB) to 8 Terabytes (TB).

The HDD consists of rotating rigid platters (disks) on a motor driven spindle.  Digital data is magnetically written to or read from the platter by read/write magnetic heads.   These heads are extremely close to the platters but they never touch them.  As a result when the heads are directed to read or write the platter spins and the head either searches and reads for magnetic changes on the platter or writes magnetic changes on the platter which is literally a series of 1s and 0s.

There are other types of digital recording devices too.  For example, Security Camera King’s product# HC-SUNGL-DVR are sunglasses with the camera and DVR included and built into the glasses.  Of course, in this case the digital recording device is not an HDD but an electronic circuit designed for digitally recording the video and audio.  These sunglasses not only have 4 GB of storage built-in, but the DVR can also accept Micro SD Expansion memory cards of up to 8 GB.

Well hopefully this article has given you enough knowledge about digital recording devices that you’ll know what to look for and how they work.  If you have any additional questions about digital recording devices and how they may apply to you please contact one of Security Camera Kings security experts today.

Computer Security Camera

Written By:
Friday, August 12th, 2011

What a better way to utilize your computer than as a computer security camera?  Thanks to today’s modern technology you can utilize your computer to run an entire digital video camera security and surveillance system, and not just the camera.

One way to get a computer security camera is to use a Web cam.  There is software available these days that will allow you to use your Web cam and computer as a security camera system. This might be useful as a Nanny cam or an unusual circumstance where only one camera is needed, but most of the time we find this impractical.

However, there are computer security camera packages out there that can handle more than one camera.  The way this is done is by adding an included PCI card to your computer.  The card functions by doing most of the work and using your computer’s CPU as little as possible.  One of the most popular products for this use is called “GeoVision PC-DVR cards).

Depending on the type of GeoVision card you purchase, your computer can be turned into a 1, 4, 8, 16, or 32 camera system.  Not only does GeoVision provide the means for making your computer security camera a system but it also has a wealth of accessories available too.  Just some of the GeoVision accessories include:

  • GeoVision remote control
  • GeoVision special keyboard
  • GeoVision POSDATA – this is a point of sale capture interface that allows you to compare your register checkout with your POSDATA because everytime a sale is made the program turns on the digital video camera to record it

However, there are several disadvantages in using your computer as a computer security camera.  For one thing, digital video places a great strain on the system due to the nature of the video.  Digital video is nothing more than many digital photographs taken in a very small time frame, such as 30 photographs in one second.  This is what is known as a “Frame Rate” and instead of being expressed as photos per second is called “Frames” per second.

Let’s take a close look at this.  One high quality digital photograph can be taken by a computer security camera and the file size that contains the data could easily be 1 MB in size.  Now, 30 of these photographs are taken in one second so that is 30 MB for 1 second.  Times 60 seconds in one minute would be 1800 MB or 1.8 GB.  There are 60 minutes in 1 hour so that would be 1800 times 60 which would equal 108,000 MB or 108 GB for just one hour of video.

That places a tremendous workload on the computer to process all that information, especially live in case the user wants to monitor the cameras in real-time.  In addition, that the amount of data for one camera many systems have 4 or more.  So you can see how the computer could be overwhelmed at this rate.

Using your computer as a computer security camera system can result in unusually slow processing times for the computer to perform other tasks and that’s why there are PCI boards that may include processors and hard drives to alleviate some of the load on the computer.

Another way the computer security camera eases the workload for the computer is by using a CODEC to reduce the size of the file.   A CODEC is an acronym for COmpression/DECompression.  This utility uses specially written programming to reduce the file size tremendously while maintaining a high degree of quality.

All of this can be included in the computer security camera board, and much of it is depending on the manufacturer.

The best solution truly is a separate digital video security and surveillance system simply because the system is tailor designed for digital video use.  The system’s DVR contains processor chips just like the CPU on a computer, but these chips a tailor designed specifically for handling digital video related tasks.

Keychain Spy Camera

Written By:
Friday, August 12th, 2011

If you are in the market for a good covert, portable digital video security camera system, you should consider a keychain spy camera.  They are small, light weight, and virtually undetectable.  Not only do they record video, but they also record audio as well.

Probably the most single important factor behind covert monitoring and recording is the camera being hidden in an object that is so common that it would never be suspected.  Such is the case with Security Camera King’s Product# HC-CARKY.  (It’s safe to say that some of the covert advantage with this product may be lost if you don’t drive a vehicle.)

Security Camera King’s keychain spy camera looks just like the remote control keychain that comes with most cars and trucks these days.  In addition, it contains its own Digital Video Recorder or DVR that records video and audio together.  As small as it is, this device packs a whopping 8 GB of storage space that can provide as much as 3 hours of video and audio recording.

The keychain device connects to any computer using a USB port and playback can be viewed on the computer using just about any media player.  The USB port also charges the built in battery which can provide approximately 2 hours of continuous use on a single charge.

The keychain fob is amazingly small (at least to contain a digital video camera and its own DVR).  It measures 2 inches x 1.25 inches x .625 inches.  The battery used is a 3.7 V 280 mAh battery.  The camera produces standard video format (AVI–Windows standard video format) with a video resolution of 640 x 480 pixels.  It records and plays back at a frame rate of 29 fps.

Many people have asked us how the keychain spy camera works; that is, how can you get a camera in such a small device.   For the remainder of this article we’ll try to explain how the camera works so you’ll at last have some working knowledge about the device.

Today’s digital video cameras are technologically amazing pieces of work.   A lot of their components have borrowed the technology from the personal computer industry.  The following explains how a typical digital camera works.  The keychain spy camera works very similar to the following.

Light is reflected off objects and the lens’ duty is to catch or gather that reflected light (which actually constitutes what we call the “image”) and focus it on a small sensor chip that is sensitive to light.  The chip is either a Charged Coupled Device or CCD or it may be a Complementary Metal Oxide Semiconductor or CMOS.  Each handles converting light energy into electrical energy a little different but both produce the same results; electronic impulses that can be used to create an image.

The CCD or CMOS in a keychain spy camera is only 1/4 inch to 1/3 inch square.  This is one of the reasons that the camera can fit inside something as small as a keychain.

The electrical impulses are routed through some Integrated Circuit (IC) chips that each has their own function as far as interpreting the impulses and producing electronic data.  Some cameras (large or small) may have light, hue, and other corrective IC chips.  Interestingly enough, the information created by the camera to create an image or image file is analog.   So the camera must also have an analog to digital converter IC chip.

Once the data is converted into digital or binary form the data is sent to the DVR where it is recorded.   In the case of the keychain spy camera, the storage medium is some sort of non-volatile flash storage (the memory isn’t lost when you unplug the device from the USB port of your computer).

When the keychain spy camera is plugged into the computer, the computer can download the digital vide file held in memory and copy it to its own hard disk drive.   Then the user can use just about any media player (such as Windows, Quicktime, etc.) to view the file.  In the case of the keychain spy camera, the video file is in AVI format which was the original video file format for Windows.

If you have any additional questions about the keychain spy camera please don’t hesitate to contact one of our security experts either via “Live Chat” or by telephone at 866-573-8878.
