Wireless IP Security Camera

One of the more recent digital video security camera system components is the wireless IP security camera. These cameras use the Internet as a network medium for the purpose of transmitting their digital video images and for allowing the user to control the camera remotely. This places the maximum power of remote accessibility as well as easy installation in the hands of the user.

It seems as if all of our electronic devices today utilize or have some sort of affiliation with, the Internet. So why shouldn’t the digital video security industry take advantage of its seemingly ubiquitous presence and cost-efficient use as well? That’s exactly what a wireless IP (Internet Protocol ready) security camera does.

By using a wireless IP security camera you can monitor your business in Ft. Lauderdale while on vacation in Tokyo. If you have a Pan-Tilt-Zoom or PTZ wireless IP security camera you can even control the camera from Tokyo moving the camera horizontally, vertically, or even zooming in on an object. You can do all this anywhere there is a broadband Internet connection and an available desktop or laptop computer and even using a 3G or 4G smartphone.

How is this possible? In the following article we’ll discuss what’s inside a wireless IP security camera and how it works, especially with the internet.

A wireless IP security camera differs from a typical digital video camera in several ways. First, a standard digital video security camera is connected to a processing and storage unit called a Digital Video Recorder or DVR. The camera is normally connected to the unit by running an RG-59 coaxial video transmission cable from each camera to the DVR. The camera transmits its video data over the cable to the DVR where it is compiled into a digital video file that is stored on a hard disk drive and may be viewed live on a digital camera security monitor at the same time.

On the other hand, a wireless IP security camera doesn’t use an RG-59 coaxial video transmission cable or any other video transmission cable. This camera has a built-in transmitter that sends its signal using IEEE802.11 or WiFi radio technology. The camera may or may not, depending on the type, also process the video data into a digital video file before being transmitted from the camera. In addition, when the signal leaves a wireless IP security camera it may be sent to an IP ready DVR over the internet, or it can be sent to any other receiving device (such as a computer or smartphone).

A wireless IP security camera also has its own built in web server technology. This allows one camera to capture video, create digital video files, and send them (using streaming technology) over the Internet to a variety of devices already mentioned. Accessing the camera is as easy as opening a standard web browser on your computer and entering the camera’s Internet address and a password. Even smartphones and similar devices such as iPhone, iPod Touch, iPad, Android, Symbian, and Windows mobile phones can remotely view and control the camera as well.

It’s important to note that a wireless IP security camera and an IP DVR system are different. The IP security camera makes a direct connection to the Internet via a wireless broadband modem or router. An IP DVR system on the other hand uses various wireless technologies to connect the cameras to the DVR FIRST. The DVR is than connected to the Internet via a variety of broadband Internet connections.

Note: For IP DVRs smartphones will require an application (app). For the iPhone and similar devices the application is available for free from the iPhone App Store on your phone. For all other types, Security Camera King offers the app for free when you download it from their website. As an additional note, please remember that the app only works with Security Camera Kings Elite Mini, Elite, and Ultimate DVRs with HDMI output. It will not work with any other type of DVR or any of Security Camera Kings DVRs.

Ultimately then, a wireless IP security camera can use the Internet to send digital video images to a variety of computers and smartphones or it can utilize the Internet as a network medium to connect several cameras to an IP ready DVR.

Security Flood Light DVR Camera

Written By:
Thursday, January 20th, 2011

Nothing says “”Gotchya!” to a potential intruder, vandal, or burglar better than a security flood light DVR camera. Thanks to modern technological improvements these devices are an entire compact digital video security system. They can be used in both residential and commercial applications and can be extremely effective when placed in the proper location.

Not only does a security flood light DVR camera help to protect and prevent perpetrators from causing damage or breaking and entering, but it also offers positive deterrence. It’s already been proven by the law enforcement agencies in London, England and New York City that the mere presence of digital video cameras deters criminal activity.

However, the security flood light DVR camera takes it one step further. Not only does it record still digital photographs or digital video images of the intruder, but once the unit senses motion, it snaps on a powerful high wattage flood light illuminating the surrounding area and “spotlighting” the intruder as well.

In addition to protecting homes and businesses, these units are great for protecting other property as well. Boat docks with electricity, barns, storage areas, specific portions of land, back entrances of retail stores, and no-trespassing industrial areas as well can benefit from the protection of a security flood light DVR camera.

The units are relatively easy to install and use as well. Basically, all that is required for installation is to mount the unit, connect it to a standard residential type power line, and select the settings you desire. Then walk away and be confident that your security flood light DVR camera will protect you and/or your family, business, or property.

Before we provide some detail about the design and function of a standard security flood light DVR camera, let’s briefly describe a typical digital video security camera system and how it works.

Most standard digital video security camera systems contain one to several cameras, a Digital Video Recorder or DVR, and perhaps a monitor. The cameras are mounted in various strategic locations and send their digital video data to the DVR unit by means of a digital video cable run from each camera to the unit, or wirelessly using radio signal transmitters and receivers.

The DVR unit, much like a highly specialized personal computer, contains a hard disk drive like those found in computers. The DVR unit processes the digital data and creates a digital video file that can be viewed live on a monitor and/or saved on the DVR for later use.

A security flood light DVR camera is basically a miniature version of the basic system without the monitor. The unit contains all the devices (sans the monitor) within one relatively small, compact fixture. The floodlight is usually a powerful 500 watt halogen flood lamp. These lights can project a powerful beam of light in a relatively wide field of vision.

Connected to the light, DVR, and the camera is an infrared motion detector. The motion detector, known as a PIR or Passive InfraRed sensor, can detect the infrared radiation emitted by the objects in its field of vision. When this “heat signature” changes greatly or rapidly, the sensor interprets this as motion. The sensor activates a relay that switches the security flood light, DVR, and camera on. Depending on the model, the entire unit switches off either after motion is no longer detected or specified time period after the initial “On” state.

When the camera is switched “on” it immediately begins capturing digital video images (or stills), with the flood light helping to provide a crisp, clear, bright picture. An on board processing chip saves the data either as digital photographs or digital video files to the DVR.

The DVR in this case is not a large hard disk drive, but usually consists of an SD card (Secured Digital card), a compact flash card, thumb drive or similar mini-portable memory device. All the user needs to do is remove the SD card, transfer the files to their personal computer and view, print, or make movies disks of the saved data.

Although a security flood light DVR camera cannot provide the extensive precise coverage of a full size standard digital video security system, it does offer an economical alternative and can be quite useful for specific situations.
