Friday, February 18th, 2011

Why would anyone want to have an electrical outlet camera? That’s precisely what you’ll want people to think. That’s what makes the electrical outlet camera so ideal for covert digital video security and surveillance applications.

Half the battle of creating a great, undetectable or covert digital video camera system is having the technology to produce a camera and Digital Video Recorder or DVR small enough to be concealed or disguised in other objects. The other half of the battle of design is finding an object that is so common that the object itself goes unnoticed.

Enter Security Camera King’s “Electrical Outlet Hidden Camera with DVR and 8GB SD Card.”

This electrical outlet camera is actually a collection of technological innovations and it’s not only a camera but a mini digital video security system all in one. There is only one thing this unit won’t do; IT WILL NOT FUNCTION AS AN ACTUAL ELECTRICAL OUTLET. But what it won’t do as far as the outlet is concerned, it more than makes up for in the .

This electrical outlet camera has the appearance of one of those outlet devices that plugs into both outlets on a wall plate, splitting them into a total of six different outlets with ground receptacles. Although the unit does not function as an electrical outlet, it does derive its power from the actual outlet it is plugged into.

The outlet contains a digital video color security camera with a resolution of 380 TVL. In addition it features automatic motion activated recording, scheduled recording, and remote control operation. The recording features include a “time and date stamp” for further documentation accuracy.

The electrical outlet camera’s built in DVR offers plenty of features too. The DVR records to SD card media so the recording capacity time is dependent on the size of the card. An 8 Gigabyte (GB) SD card is included which allows you to record up to 144 hours of video AND audio. However, if that’s not enough, purchase your own additional SD card(s) with a greater capacity (a 16 GB SD card for example) and extend your recording time to up to 288 hours.

The built-in DVR in this electrical outlet camera uses the MPEG-4 CODEC. A Compression/DECompression utility or CODEC is used to compress large digital video files into smaller ones without losing a significant amount of quality. Digital video security cameras actually create their video footage by taking several digital photographs in rapid succession. When played back in rapid succession these photographs fool the human eye into seeing a fluid motion video. Motion video can be created with as few as 12 photographs (also known as “frames) taken every second up to as many as 30 frames per second or fps. The following lists the approximate maximum recording times based on the use of the included 8 GB SD Card:

Resolution at 640 x 480 and 12 fps
• High Quality–approximately 8 hours recording time.
• Medium Quality–approximately 48 hours recording time.
• Low quality– approximately 72 hours recording time; and for

Resolution at 320 x 240 and 30 fps
• High Quality–approximately 16 hours recording time.
• Medium Quality–approximately 96 hours recording time.
• Low Quality–approximately 144 hours recording time.

Once you have finished recording, pull out the easy-to-remove SD card and download the digital video files right to your personal computer where you can view, copy, and/or archive the files. For some computers without a multi-media card reader, you may be required to purchase one of these for your computer.

But that’s not all! The included miniature DVR is more that just a recording device, it can play back the files as well. If you don’t have a computer, you can still view your captured color digital video by using the included RCA cable to connect the unit to your television.

This electrical outlet camera is great for use a home or office security or surveillance camera. Since the unit is totally self-sufficient or a stand alone, that it, it doesn’t require any other devices to work, it can be used in a variety of applications. Retail store merchandise monitoring, employee monitoring in the office, as a nanny cam in the home, and warehouse monitoring are just some of the possible uses for this device.

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:
420 TVL Motion Detector Camera. This is a high quality camera hidden inside a motion detector casing.

PTZ Web Cameras

Written By:
Monday, February 14th, 2011

Pan-Tilt-Zoom or PTZ Web cameras bring two powerful punches to the benefit of the digital video security and surveillance world. Not only can these cameras allow your system to reap the powerful benefit of camera movement (the first punch) but also make use of the Internet as a means for networking (punch number two).

PTZ cameras have been used in the video security and surveillance world for quite some time; even when the systems operated in a totally analog format. However, as technology has increased, cameras have become more powerful in function and lighter in weight as well as more versatile in application. Now, digital video cameras with PTZ functions are much more easily controlled.

Older analog systems usually required a separate, big, bulky controller board that connected to the Digital Video Recorder or DVR unit to manipulate PTZ cameras. This board was proprietary in that it was the only device that could be used to pan, tilt, or zoom PTZ cameras. However, since video security cameras have left the analog genre and become digital, there has been some merging that has occurred with the personal computer world.

There are still separate controller boards available for use with digital PTZ cameras, but these cameras can also be controlled by using software and a personal computer. Many systems are now based on personal computer Graphical User Interfaces or GUIs and the PTZ functions can be controlled by a computer mouse or keyboard strokes.

One PTZ web camera can literally take the place of several non-PTZ cameras. Since these cameras can move in two dimensions and enlarge views as well, they can cover the field of vision that would normally take several non-PTZ cameras to cover. PTZ web cameras have many uses and are great for monitoring large areas such as parking lots, industrial property, and even highways.

Having one or more PTZ cameras is certainly a powerful advantage, but if these cameras are also PTZ Web cameras, their versatility in application and ease of access is incredibly increased. A PTZ Web camera utilizes the Internet as the networking solution for the system thereby broadening the scope of access globally.

PTZ Web cameras are also known as IP ready or Internet Protocol ready cameras. These cameras have built in web server technology so that the camera can connect directly to the Internet. Once the Internet connection has been established these cameras can be used in many ways.

For example, more than one PTZ Web cameras can be networked together using the Internet to carry their signals to a remotely located Digital Video Recorder or DVR unit that can record their digital video data. Another way PTZ Web cameras can be used is as individual cameras that use the Internet to send their digital video data to personal computers which are used to monitor and record their digital video data. This has great implications.

PTZ Web cameras that are connected to the Internet can be accessed anywhere in the world there is broadband Internet access. This instantly converts the accessibility of the camera from a local system to a globally accessible system. In addition to monitoring these cameras anywhere there is Internet access, these cameras can also be controlled remotely from the same point.

This access is not limited to only a personal computer with an Internet browser, but 3G and 4G smartphones can also monitor and control these cameras. This means you could be sunning on the beach in Australia while panning, tilting, zooming and monitoring your PTZ web camera security system in Paris. What more is the only thing needed to use your smartphone to do this is the small software application or app; and Security Camera King makes smartphone apps available for their featured security systems for free.

In addition, PTZ Web cameras can also be programmed to track or follow moving objects. This auto-tracking option is great for keeping a close eye on moving objects in the cameras field of vision, especially if the field of vision is not expected to contain moving objects.

So if you have the need for a digital video security cameras that can “look” left and right, up and down, and enlarge the view of objects, consider purchasing PTZ cameras. However, if you would like a camera that does all this and can be viewed and controlled anywhere in the world there is broadband Internet access, consider purchasing PTZ Web Cameras.

Motion Activated Recording

Written By:
Thursday, February 10th, 2011

Conservation is the key term in reference to motion activated recording. In the following article, we’ll take a look at how digital video security and surveillance systems go about doing this and why conservation is a key term associated with this type of monitoring.

Digital video camera security systems can initiate motion activated recording in different ways. One of the most common ways to provide motion activated recording is to use a digital video camera with a built-in motion detector. Digital video security cameras equipped with motion detectors begin recording video when motion is detected and stop when motion is either no longer detected or after a designated (pre-programmed) time period.

The motion detector itself is called a PIR or Passive InfraRed sensor. This sensor constantly monitors the passive infrared signature of the camera’s field of vision. When a significant change in this infrared signature occurs (such as when a person, vehicle, or other object passes by) the PIR interprets this change in the infrared signature as motion.

The PIR sensor on motion activated recording cameras is electronically connected to a relay switch. When the PIR detects motion, the relay is energized to the “On” position which turns on the camera and begins the process of recording. When the infrared signature in the camera’s field of view becomes constant, the sensor interprets this as non-motion and the relay switch is then open, shutting the circuit to the camera off. (Many cameras have an intermediary circuit that is programmed to shut the camera off after a time delay in addition to or after motion is no longer detected.)

One of the biggest benefits of PIR motion activated recording is conservation of digital video security system resources. For example a typical motion activated recording system may have one or more motion activated digital video cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and an optional monitor. The DVR usually consists of a hard disk drive, like the one in most personal computers and in miniature systems may consist of SD cards, small Integrated Circuit (IC) chips, or other portable non-volatile media.

Even though technology advancements are yielding larger capacity and more efficient storage devices, regardless of the type of storage on the DVR, the capacity is still finite. Furthermore, the digital video files created by the cameras and stored on the DVRs are extremely large files. To keep file sizes as small as possible without losing significant quality, COmpression/DECompression or CODEC utilities are used. These utilities may be in the form of software or a hard-wired IC chip.

CODECs greatly improve the storage capacity of any given drive, conserving on system memory. This is important because whenever storage capacity is reached, the newest digital video files are re-recorded over older digital video files. If the files are archived before hand the data could be lost. There are several ways of improving efficiency in addition to using a CODEC. A larger capacity storage medium can also increase re-recording loop times, handle multiple camera recordings at once, and provide storage space for software programs and other necessary binary information.

Another way to greatly improve the storage capacity and efficiency of the camera-DVR relationship is to only record what is necessary. PIR motion activated recordings or PIR motion detector cameras do exactly that. By recording video only when motion is detected, a tremendous amount of memory on the storage medium is conserved. For some applications, motion detection would only be detected if there is a breach in security (banks and retail stores after hours for example) and this could mean no need to record for days or even months.

Memory is not the only resource that is conserved by motion activated recording cameras. Many users these days prefer the use of totally wireless cameras. These cameras send their digital video data via radio signals to a corresponding receiver that is connected to the DVR or to a DVR with a built in receiver. However, these cameras still require a power source which indicates the use of some sort of power supply carried by a wire to the camera – unless the camera is battery operated.

Battery operated cameras may use standard one-time use batteries or rechargeable batteries. Regardless of the type of battery, motion activated recording drastically conserves battery power as the PIR sensor demands a very small drain on the camera batteries as does digital video recording.

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 this page.)

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.
