Most covert security and surveillance monitoring systems use a hidden color camera. There are definitely useful times when covert digital video recording is necessary and thanks to 21st century technology, the equipment for this purpose is not only available, but reasonably priced as well.

What makes a hidden color camera possible? The extremely small but highly accurate and efficient parts including, not only the mechanical (lenses for example) but the electronic (sensors, digital-to-analog converter for example) components of the camera as well, have yielded a miniature but powerful product that is easily hidden or disguised.

Hidden color cameras can be a component as part of a larger digital video security and surveillance system or they can be a miniature system all contained in one object. A digital video security system may consist of several different devices, but generally a basic system has three components that include the camera or cameras, a Digital Videos Recorder or DVR unit that also contains the Digital Signal Processor or DSP, and one or more monitors.

The digital video hidden color camera captures video images that it passes on to the DVR unit. The DVR unit’s DSP compiles the digital data sent to it by the camera can creates a digital video file that can be viewed on a monitor or saved on the DVRs hard disk drive for later viewing or archiving.

If the hidden color camera is an all-in-one unit, it usually consists of the camera and some sort of DVR. Thanks to Integrated Circuit (IC) chip technology, the necessary electronic circuitry and be constructed small enough to create a stand-alone hidden color camera that can be placed inside a typical ball-point pen casing.

Standalone all-in-one miniature hidden color camera units do not contain all of the components or sophisticated circuitry of their typical full size standalone cousins. Therefore, there are certain limitations for these smaller units. For example, the DVR used in a ballpoint pen version of a hidden color camera will obviously not have the storage capacity of a full size DVR unit with a hard disk drive.

Often, objects as small as a pen have their own limited built in electronic memory chip. Since their normally is a limitation on space, the memory chip is often limited to a relatively small capacity. Another option if the hidden color camera device is large enough is to use various types of portable memory media such as SD cards or other types of flash memory media.

In addition, these all-in-one hidden color cameras usually have a reduced resolution to conserve on file size as well. Their power source may be as small as a watch battery or they may be connected to an external power source via a pair of small wires. Nonetheless, these miniature cameras still capture good quality video and our excellent choices for covert security and surveillance purposes.

Security Camera King offers a wide variety of miniature standalone hidden color cameras for purchase. If you are interested check our “Hidden Camera Systems” and “Hidden Security Cameras” section by clicking the on “Security Cameras” then “Hidden Camera Systems” and also “Hidden Security Cameras” on the our navigation bar on the left. Just some of the systems we offer in addition to the “Hidden Pen Color Camera With Audio” include the “Portable Lighter Hidden Camera With Built-IN DVR & Audio,” the “Sunglasses Hidden Camera with Built-in DVR & Audio,” and the “Portable Car Key Hidden Camera with Built-In DVR & Audio.”

As mentioned earlier, hidden color cameras can also be one of the components of a larger, full-size digital video security and surveillance system. These devices are just cameras; that is, they do not usually include a DVR or any other components of a digital video system. They normally connect to the system either by a video transmission cable or wirelessly.

Wireless hidden color cameras have the extra advantage of being placed just about anywhere. These cameras are also small enough that in addition to being disguised as other objects, they can be mounted alone in areas or positions that keep all but the lens of the camera hidden.

If you are interested in purchasing one of these hidden color cameras, in addition to the two on-line catalog pages mentioned above under the “Security Cameras” heading, also check out our “Wireless Hidden Cameras“.

Spy Camera CCTV

Written By:
Thursday, December 2nd, 2010

Covert digital video camera monitoring and recording is sometimes referred to as spy camera CCTV. Although the term “spy” may conjure up images of secret agents, under cover operatives and the like, a spy camera CCTV system can have very practical applications suited for every day residential and commercial applications.

It is possible to describe process of digital video monitoring and/or recording as either overt or covert. Overt digital video systems operate without an attempt to disguise or hide the equipment in any manner. In fact, many systems are installed in such a way as to be obvious, since there is an added advantage of deterrence of criminal acts associated with video security systems.

However, there are many applications where the process of digital video monitoring and/or recording is required without the subject being aware of the presence of any video security equipment. These are called covert video systems or spy camera CCTV (Closed Circuit Television). Sometimes the interpretation of the words “spy camera” are so loosely interpreted that some use it to mean any type of video security type camera.

The acronym “CCTV” in spy camera CCTV is basically a term that originated to describe or differentiate the system from an “open” broadcast system. When video cameras were first used for security systems, the cameras were analog cameras that were basically miniature versions of the video cameras used in television stations to record live shows and newscasts. Television cameras however, sent their signal to a powerful transmitter and antenna that openly broadcast the video to anyone that could receive it (owned a television).

Video security systems including modern digital video security systems send their video signals via a video transmission cable, usually an RG-59 type coaxial cable. These cables carry the signal from each camera to the video recorder or Digital Video Recorder (DVR) and are not openly broadcast, hence the term “Closed” Circuit Television. Spy camera CCTV is covertly designed video monitoring and recording that is wired in a closed circuit.

With ever increasing technological advances, including wireless digital video cameras and Internet Protocol (IP) ready cameras, it may be necessary to broaden the definition of CCTV a bit. Since these cameras do broadcast a signal using radio waves or utilize the Internet as a networking medium, it is difficult to say they are working in a closed circuit. However, the intent is still the same and that is; the video signal is only intended for a specific receiver or receivers and is not intended for open broadcast to the public.

Spy camera CCTV systems today are exceptionally good and disguising or hiding themselves. That’s because the digital video cameras have been able to take advantage of the tremendous technological innovations in computing and electronic circuitry. Sensors, lenses, and Integrate Circuit (IC) chips can be integrated into unusually small packages making the camera easy to hide or disguise.

For example, Security Camera King offers an ink pen (our product # HC-PEN) or a wrist watch (our product # HC-WATCH) that contain a color spy camera CCTV complete with a color video camera, audio recording, and a Digital Video Recorder or DVR!

Other spy camera CCTV systems may include several hidden or disguised cameras or a combination of covert and overt camera types. Security Camera King offers a huge selection of spy camera designs including cameras disguised as:
• Wall clocks;
• Exit signs;
• Buttons;
• Screw heads;
• Speakers;
• Telephones; and
• Many other objects.

These cameras can be connected to typical digital video monitors and DVRs to create custom designed spy camera CCTVs. Not only have these systems benefited from technology that permits them to be incredibly small, but they have also benefited from technology to improve in function.

For example, there are two different types of electronic sensor chips used in digital video cameras today that transfer the light from images into electrical energy that can be used to create video images. Not only can these sensor chips create video images, but they are inherently able to detect infrared light (light that the human eye cannot see) as well. With the proper filters and lights, these cameras can record video in total darkness conditions.

Surveillance Spy Cameras

Written By:
Wednesday, December 1st, 2010

If you need to keep an eye on someone without them getting an eye on you try using surveillance spy cameras. Actually, these cameras not only allow you to keep an eye on someone but also something like a pet, a house, a boat or some other type of property.

What exactly is a surveillance spy camera? Typically, a surveillance spy camera is a special type of digital video security and surveillance camera.

A digital video security camera usually has one of three different shapes. Box cameras look like rectangular box shapes and are typically mounted on walls, posts, and other areas. Bullet cameras resemble box cameras but have rounded ends, hence the name “bullet.” Dome cameras are normally flush mounted on a ceiling or wall and have a small protective bubble or dome that covers the camera. The presence of these cameras is somewhat obvious and their usually is no attempt to hide or disguise them.

Surveillance spy cameras on the other hand are digital video cameras that are much smaller, so small in fact that they are often hidden or disguised as other objects. They may contain their own Digital Video Recorder or DVR and power supply and be an entire standalone system, or they may require an external power supply and be incorporated into an entire digital video security system that has both hidden and visible cameras, a standalone DVR with a Digital Signal Processor or DSP, and a monitor.

How can surveillance spy cameras be so small? Let’s look at how a full-size digital video security camera works then will look take a look at a surveillance spy camera. Digital video cameras have three main components within the camera; the lens, a sensor chip, and the electronic circuitry used to operate the sensor chip and convert its information into digital data (a series of 1s and 0s).

The lens is a highly machined mechanically functioning glass (or plastic) that focuses the cameras field of view onto the sensor chip. Generally, the higher quality and type of lens, the higher quality of the video produced. Lenses determine how far, how wide, and how detailed the target area will appear.

There are two types of sensor chips, a Charged Coupled Device or CCD and a Complimentary Metal Oxide Semiconductor or CMOS. These two chips work a little differently but accomplish the same objective, transferring light energy into electrical energy. These chips are usually square or at least rectangular in shape and usually range from 1/4 inch to 1 inch in size.

Electronic circuitry is used to interpret the chip, read its information, and convert it from an analog signal into digital data. The electronic circuitry may also provide other functions such as audio recording and movement of different camera parts.

Surveillance spy cameras contain the same components but the components are designed to be very, very small while still performing the needed task. For example, most of these cameras are extremely small. Their lens is not a full size variable lens but is a very small wide angle lens instead. This eliminates the need for a large lens attachment.

Secondly, surveillance spy cameras usually use one of two sizes for their CCDs or CMOSs, 1/4 inch or 1/3 inch. The incredibly small sizes of these sensor chips allows them to be used (hidden or disguised) in very small objects such as ink pens (see Security Camera King’s product # HC-PEN for example) or wristwatches (see our product # HC-Watch).

Finally, with the latest improvements in Integrated Circuit (IC) chip technology, incredibly complex circuits can be made in circuit chips that are only 1/4 inch in size also. For example, the electronic circuitry needed to activate and read the sensor, convert the information into digital data, and transmit it wirelessly to a corresponding receiver can be fit with a IC chip less than an inch in size.

In addition, surveillance spy cameras can also have their own miniature DVR in the form of a small memory chip. As computer memory technology advances, these chips become smaller yet hold more data. The data on the memory chip can be downloaded to a personal computer using a USB cord.

Security Camera King has a very wide assortment of surveillance spy cameras available for purchase. These cameras come in all sizes and types (view the products individually on-line by clicking on the left hand side of the page “Security Cameras” then “Hidden Security Cameras” or “Wireless Hidden Cameras” or “Hidden Camera Systems.”
