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.

How To View Security Cameras Remotely

Written By:

There are many types of remote security cameras and many ways to view the cameras remotely. There are even security cameras designed for home use that are wireless and can be viewed on a standard television. However, when we speak of most robust, professional security systems that permit remote viewing, we are talking about IP cameras or IP systems. IP, which is a computer technology abbreviation that stands for Internet Protocol, permits a variety of remote viewing options for security cameras.

There are a few methods for making your security camera “remotely viewable,” however; the key ingredient for all of them is the idea of Internet Protocol or networking. Although there are several possible variations for capturing, sending, and storing the camera’s signal the basic process works like this.

An IP security camera system works by converting the camera’s video signal into a digital file that can be transmitted via a networking system. Depending on the type of system, the signal, by way of the local network, can even be sent to the internet making the security camera remotely accessible from anywhere internet is available.

Many cameras connect to a DVR or Digital Video Recorder system. They do this by a physical connection through a cable or by utilizing various wireless technologies (similar to the wireless technology used by wireless computer routers and receivers). Most wireless cameras have a useful maximum range of approximately 300 feet.

Regardless of how the camera’s signal is transmitted, it is normally transmitted to a personal computer, DVR system, IP video server, or directly to the internet. If the camera is an older analog-type CCTV camera, the signal will be transmitted to a “capture card” that will “capture” the analog video and convert it into a binary or digital file form. The purpose of transmitting the camera signal to a personal computer, DVR system, or IP video server is to prepare the digital file for “streaming” so that it can be sent over a Local Area Network (LAN) or the internet. Streaming technology allows for the digital data to be transmitted and viewed in real time, while maintaining small file sizes to prevent overloading the network. Personal computers, DVR systems with specific, dedicated video networking circuits, and IP video servers can each be utilized to do this “file processing” work and transfer the final product to the LAN or internet.

Once the video signal has been prepared by the system and has reached transmission to a LAN or the internet, viewing opportunities are seemingly endless. The camera, video system, or IP video server normally comes with software that prepares the signal and provides software applications for viewing. Based on the file type and application software, the camera can be viewed remotely in a variety of ways.

Some of the easiest remote viewing camera/systems/software allow the user to view the camera using an internet web browser. Some applications may even allow the user to control the camera through the web browser while others may use some sort of proprietary network video recording (NVR) software.

In addition to using personal desktop computers, you can also view your security cameras remotely using just about any personal communication appliance, provided the device supports the format that the security system is using. That means you can view real-time, live images from your camera(s) using a laptop computer, cell phone, or even a PDA. It wouldn’t be surprising to see an application for an iPod if there isn’t one already out there. In fact, some remote systems provide an alert to the user via e-mail if the camera has detected motion and has started recording activity.

Remote viewing expands the possibilities and capabilities of security cameras In various ways. The user can check their cameras at work or while on travel. Constant monitoring systems can be installed and signals transmitted to a remote 24/7 monitoring service that can alert the user of any activity or suspicion. The possibilities are forever becoming endless.
