Motion Detector Hidden Camera

Written By:
Tuesday, April 19th, 2011

A motion detector hidden camera can be just what the situation calls for when covert monitoring is required.  These hidden cameras can be used just about anywhere and provide a remarkably good digital video image.  There are a few different types of motion detector hidden cameras and in the following article will take a look at each.  Before we look at individual motion detector hidden cameras, let’s quickly review how a digital video security camera system works.

Modern digital video security camera systems are component systems.   That means that each major device used in the system doesn’t have to be the same brand, type, or made by the same manufacturer.  This alone has great implications for a motion detector hidden camera because it means you can always add this camera to your existing system without any major difficulty.

A typical digital video security and surveillance system consists of three major components (devices); one or more cameras, a Digital Video Recorder or DVR, and a monitor (which is needed for setup after which its use is optional).  Since this article focuses on motion detector hidden cameras, we’ll take a closer look at how the digital video camera works.

The primary function of a digital video camera is to transfer an image created by reflecting light into an electronic signal that can be recreated and displayed on a monitor and/or saved as a digital video file.  The same holds true for the motion detector hidden camera.

The camera accomplishes this by using lenses, sensors, and Integrated Circuit (IC) electronic chips.  Each camera has a “field of vision”; this is the area that the camera can “see” through its lens.  The image the camera sees through the lens is made up of reflected light.  The lens gathers the light image and focuses it onto a very small sensor chip ranging from 1/4 inch to 1/2 inch square.

There are two such sensor chips available for use; however both yield the same results, transferring light energy into electrical energy.  The Charged Coupled Device or CCD and the Complementary Metal Oxide Semiconductor or CMOS.  Both sensors produce a video image in the end, but in the process of getting there, their approach is different.

The CCD and CMOS are fairly comparable these days, but they both still have different slight advantages.  Typically, the CCD creates a higher resolution and higher quality image, but it does so at the cost of needing electrical power.  The CMOS doesn’t create as detailed an image as the CCD, but it is advantageous to use in standalone motion detector hidden cameras because it uses much less electrical power.

So, for applications that include the use of a motion detector hidden camera, the camera sensor will vary depending on whether the camera operates off of a full-time power supply or batteries.  Normally, one is apt to see more CMOS sensors used in standalone battery operated cameras and the CCD used when the camera is part of a digital video security system that has a full time power feed.  This is not a hard and fast rule though, because as technology continues to advance CCDs are created that use less power and CMOSs are created that deliver a higher quality digital video image.

How covert can a hidden camera be when it is hidden inside a motion detector, something that is used for an alarm system?  The answer is very covert.  If you have an existing alarm system chances are you have existing motion detectors mounted for that system or perhaps you have existing motion detectors to control the rooms lighting.  At any rate, these devices are very common in business and home applications.  No one would suspect that the motion detector would also be a digital video camera.  (Incidentally, most motion detector hidden cameras DO NOT have a functioning motion detector.  The available room inside the detector is usually consumed by the camera.)

Security Camera King has three different types of motion detector hidden cameras available for purchase; a wired 420 TVL motion detector hidden camera (Product# CV-LXPIR), a wireless black and white (Product# HC-MOTIOD-G) or color (HC-MOTIOD-GC), and a 380 TVL (Product# HC-MOTION-DVR) standalone camera with its own built-in DVR.

High Quality Hidden Camera

Written By:
Friday, February 18th, 2011

There are situations when designing your digital video security and surveillance system that you should consider using a high quality hidden camera. These cameras come in a variety of types, shapes, and sizes and connect to your system just like any other digital video security camera.

Today’s technology has allowed the digital video camera to be incredibly small and still produce a full-size high quality video image. Because of this, a high quality hidden camera can be disguised or concealed in just about any object. This is important when effective covert security and surveillance monitoring is required because the key to success is not being detected.

It seems as though there are almost as many high quality hidden camera models available as there are non-hidden models. As usage becomes more popular and demand increases, so does the variety of objects arrive on the market with these cameras embedded in them.

Most high quality hidden cameras use a 3.7 mm diameter lens and a 1/4″ or 1/3″ sensor. The sensor is what the lens focuses the light image on. It is also what is used to convert the light image into a potential electronic digital video image. There are two different sensors and every camera uses one; the Charged Coupled Device or CCD and the Complementary Metal Oxide Semiconductor or CMOS.

The rest of the internal working parts of a high quality hidden camera are just electronics. “Just electronics” doesn’t mean to lessen the sophistication and power of the technology, rather electronic technology as exponentially increased in the past several years. “Just electronics” means to imply that although there is a lot of circuitry, it can be accomplished by using very small Integrate Chip (IC) chips in a small amount of space.

Security Camera King offers a vast supply of high quality hidden cameras, hidden camera systems, and wireless high quality hidden cameras. The following is just a partial list of the items we offer:

Hidden Camera With SD Card

Written By:
Wednesday, February 9th, 2011

There are times when covert camera monitoring and recording are necessary and one of the best devices for this purpose is a hidden camera with SD card. Thanks to recent technological advances in the computer world as well as in general electronics, a camera can be made as small as to fit in the shell of an average writing pen.

When it comes to the appearance of a hidden camera with SD card, there are many types from which to choose. These cameras come in “bare-bones” mini versions, where the camera is basically undisguised but is small enough to be hidden, to disguised versions that look (and often times function) as clocks, mirrors, safes, stuffed animals, and many more.

But what exactly is a hidden camera with SD card and how is it able to work? We’ll answer those questions and more in the following article.

The secret behind the success of the hidden camera with SD card is its incredibly small size. Another technological feature is its relatively low demand for power consumption. Yet another is the ability to save digital video images to an SD card, a relatively small device that can pack a big punch in memory capacity these days. Let’s start from the beginning.

A digital video security camera system works by capturing color digital video images with the camera, transmitting those images to the Digital Video Recorder or DVR unit, and saving them on the DVR’s hard disk drive and or displaying them on a monitor. Technically, a monitor is only needed for the system to set it up; that is, fine tune and adjust initial settings. However, if the user wants to monitor the digital video live (or later) the monitor will be needed. The important point here is that a digital video system can consist of just a digital video camera and DVR.

Basically that’s exactly what a hidden camera with SD card is; a digital video camera with a DVR. The key component of the digital video camera is the sensor that is used to create the digital video image. One of two different types of sensors, a Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor is used. Generally speaking, a CCD provides the highest quality image at the price of power consumption while a CMOS provided a good quality image at a much lower demand for electrical power.

As technology continues to increase, the power demands for the CCD become much less and the quality for the CMOS becomes even better. Since many hidden cameras with SD card are standalone units placed inside other objects to disguise their appearance, power consumption may be an issue. For that reason many hidden camera with SD cards use CMOS sensor chips.

Although the CCD and the CMOS work a little differently, they both produce the same outcome, a relatively high-quality digital video image. They do this by transferring light images into electrical impulses. These impulses can be measured and compiled into data that creates a digital video image.

One of the most impressive features of digital video cameras is that they can produce these high quality digital video images with a CCD or CMOS the size of a square that is only 1/4 inch! In addition, a wide angle lens is usually used to focus the image on the sensor and these lenses are often as small as 3.7 mm in diameter. Obviously, the small sensor chip and lens combination “paves the way” for camera to be used in other devices as a hidden or disguised camera.

After the camera has created the data for a digital video image micro-circuit technology take over from there. First, an on-board analog-to-digital converter chip transfers the analog data into digital data. Then another circuit compiles and condenses the data to create a digital video file. The digital video file is saved by the DVR, however this cameras DVR records to an SD (Secure Digital) card instead of a hard disk drive.

SD cards are non-volatile memory containers that are used in many electronic devices such as cameras, cell phones and MP3 players. All the user has to do is remove the SD card, plug it into their computer, and download the digital video file created by the hidden camera with SD card.

On-board power for hidden cameras with SD cards may be supplied by a battery, or the camera may actually tap into the power of the device in which they are hidden.

Hidden Camera In TV

Written By:
Tuesday, February 8th, 2011

Ever need to watch those who are watching? That’s exactly what a hidden camera in TV can do. In fact the possibilities for different types of hidden cameras are nearly endless these days, thanks to 21st century electronic technology.

The current technology that abounds is so compact and efficient, that a hidden camera in TV is rather simple, especially considering the fact that we currently have hidden color cameras that are made to look like the head of a typical Phillips screw. (See Security Camera Kings product# HC-SCREW-WC or go to http://www.securitycameraking.com/wired-color-screw-camera-58967-prd1.html).

Putting a hidden camera in TV is easy because there is usually lots of spare room inside the television set case to allow for the camera and accompanying electronics. Who would suspect that the television is actually watching them?

Perhaps the real question here is not how they put a hidden camera in TV, a screw, a stuffed animal, a clock, or just about any other object but what is it about the technology that makes such a thing possible? In the following article we’ll describe how a miniature hidden camera works and mention some the technological improvements that have occurred over the past few years to make this possible.

There are two types of digital video security and monitoring, overt and covert. Overt monitoring occurs when no attempts to conceal, disguise, or hide the activity to monitor or record images are made. Covert monitoring is just the opposite; the camera and other equipment is hidden, concealed, or disguised so as not to readily reveal its presence. In the world of security and surveillance, both overt and covert monitoring is needed. Thus, the demand has created the need for a device like a hidden camera in TV.

Covert monitoring devices may include just the camera or it may include an entire miniature digital video security camera system. A typical full-size digital video security system not only has cameras, but a Digital Video Recorder or DVR and an optional monitor as well. Hidden miniature digital video security camera systems also include the camera, but in addition, contain a miniature DVR as well. But before we get ahead of ourselves, let’s talk about the technology that allows this to happen.

First a full-size standalone digital video system uses digital video cameras that send their digital video signals to the DVR unit. The DVR unit also contains a highly specialized computer processor called a Digital Signal Processor or DSP. The processor is like the processor in a personal computer but is designed to operate specifically to deal with digital video data. The DSP gathers the digital video data sent to it by the digital video camera and creates a digital video file that can be viewed live on a monitor and/or stored in a digital file format on a hard disk drive on the DVR.

Miniature systems, like a hidden camera in TV system, also have a camera and a DVR. However, the DVR circuitry is contained on a small Integrated Circuit (IC) chip and is either stored in on-board (another type of IC chip) memory or on an SD card or similar device. As technology improves, memory chips become smaller and smaller while their capacity for storage becomes greater. This is just one of the features that provides for making miniature digital video security systems possible.

As for the cameras, there are several technologies applied here to make the devices incredibly small while still yielding fluid, relatively high-quality video. First, many hidden, miniature digital cameras use a highly refined wide angle lens. This lens provides the camera with a significantly wide field of view even though the lens itself is often only 3.7 mm in diameter.

Next the electronic sensor chips used to convert the focused light reflected from the image through the lens can be incredibly small. Typical sizes for these sensors called Charged Coupled Devices or CCDs or Complementary Metal Oxide Semiconductors or CMOSs is 1/4, 1/3, and 1/2 inch square – and that is for full sized cameras.

Finally, as already mentioned IC chip technology continues to get smaller and more sophisticated over time. This allows for an analog-to-digital converter circuit and transmitting circuits to exist in miniature IC chips. So when all of these technological improvements are packaged neatly and tightly together, many covert recording devices are possible, including a hidden camera in TV.

Hidden Spy Camera

Written By:
Friday, November 19th, 2010

There are times when it is necessary to monitor and/or record video using a hidden spy camera. Often, these require situation specific digital video cameras and systems. Security Camera King offers a huge selection of hidden spy cameras to meet all of your covert video capturing needs.

Although digital video security camera systems reap an added benefit of deterring criminal activity, there are some applications where it may be necessary to record video with out be obvious. This is usually accomplished by disguising a very small video camera within the body of another object. The other object may or may not always function for the purpose that it appears it was manufactured.

Modern technological developments in lenses, video image sensor chips, and Integrated Circuit (IC) chips have yielded the smallest of cameras. The smaller these digital video cameras are, the easier it is to disguise them as hidden spy cameras. In fact, technology has become so advanced in producing compact cameras that they can be hidden within a wristwatch (check out our product # HC-WATCH Hidden Watch Color Camera with Audio) or even an ink pen (checkout our product # HC-PEN).

Hidden spy cameras may be either wireless or wired. For a vast selection of wireless spy cameras click on “Wireless Hidden Cameras” under the “Security Cameras” heading on the left side of our web page. For a large selection of hidden spy cameras that are wired or a standalone camera unit, click on the “Hidden Security Cameras” heading under the “Security Cameras” heading. However, if you need a camera and built in Digital Video Recorder or DVR, then click on the “Hidden Camera Systems” heading under the “Security Cameras” heading.

Digital video cameras produce electronic data that is used to create a digital video file. Digital video files can be read and understood by Personal Computers (PC) and Macintosh (MACs) alike. Since digital video files are a type of computer file, they can be stored on memory chips designed for computer use. Recent advancements in the construction and development of memory chips have yielded chips with a greater memory capacity and a much smaller design.

Hidden spy cameras take advantage of this technology to produce micro-camera systems with small size memory chips. The final product yields a self contained high-quality digital video camera as well as a DVR. The actual memory chip media for these cameras may be SD cards, Thumb Flash drives, or built-in memory chips that can transfer their data to a computer using a USB cable.

These hidden spy cameras and hidden spy camera systems may or may not contain their own power supply, depending on the camera or system. For example our product # HC-SPRNK-WC Wired Color Sprinkler Hidden Camera requires an external power source. This camera is disguised to look just exactly like an emergency fire sprinkler head. However, like regular digital video cameras, this hidden spy camera requires power from a low-voltage Direct Current (DC) source. This is normally supplied by a power distribution center or a plug-in transformer/adapter. On the other hand, our Hidden Watch Color Camera with Audio previously mentioned, contains its own rechargeable battery and 4 Gigabytes of on board memory as well.

Security Camera King “crowns” our competition with a tremendous offering of hidden security cameras. The following is just a partial list of the hidden spy camera types of we have to offer. These cameras are disguised as:
• Motion detectors;
• Smoke detectors;
• Sprinklers;
