Web Based Wireless Camera Home Security

Wednesday, October 13th, 2010

Perhaps one of the most recent technological innovations in the area of digital video security is web based wireless camera home security. In the following article we’ll talk about what it is and how it works and hopefully provide you with enough information so you can decide if it is right for you.

Simply put, web based wireless camera home security is the use of wireless digital video cameras and the internet to provide security and surveillance for your home. A web based wireless camera home security system may be self- installed or installed by a professional. Likewise, the system can be personally monitored by you or by a 24 hour, 7 days-a-week professional monitoring service.

For the sake of information, we’ll separate web based wireless camera home security into two categories based on how the video signal is sent to the internet. One method involves the digital video camera sending its video transmission data via radio signals to a corresponding receiver, server, or DVR and the second method involves the digital video camera directly communicating with the internet. Each method accomplishes the same goal, allowing the home security cameras to be monitored, and in some cases controlled, via the internet.

Wireless digital video cameras can become web based wireless camera home security systems when they send their video transmissions via radio signals to receivers, servers, or DVRs which contain the technology to act as web servers and send digital information via the internet. These cameras normally use the 900 MHz or 2.4/5.8 GHz band technologies to transmit their video data. Incidentally, these radio band technologies are the same type used for land based wireless telephones.

These cameras contain a built-in transmitter and antenna with which they send the video data. This data can be sent to a corresponding receiver which is connected via a video transmission cable to the DVR. The DVR processes the signal and sends it via built in web server technology over the internet.

This method is not restricted to using a DVR. In fact the receiver can contain the web server technology and be connected to the internet for monitoring purposes and if so desired, a personal computer or DVR can be remotely located anywhere in the world there is broadband internet access to record the digital video files. The key here in this method is that the cameras transmit to another device that prepares the video data for transmission over the internet.

The alternative web based wireless camera home security method is to use wireless digital video cameras that can connect directly to the internet via a wireless modem or router. These cameras normally contain their own web server processing technology so they can package their video transmission data in a form that is compatible for internet use. These cameras usually send their signals via IEEE 802.11 format or WiFi to a corresponding wireless device such as a home router or wireless broadband modem which in turn is connected to a broad band internet connection. The cameras (as well as the DVRs mentioned in the first method) are usually referred to as wireless IP or internet protocol ready.

Regardless of which method is used to transmit the digital video cameras’ signal over the internet, a GUI or graphical user interface must be used to view and sometimes control the digital video cameras. For IP ready cameras, servers, or DVRS the GUI may be any typical web browser such as Windows Internet Explorer. On the other hand, depending on the manufacturer, the GUI may be a proprietary software program that must be installed on the device used to access the cameras’ data.

Web based wireless camera home security can be incredibly versatile in that the user can be notified via email based on a variety of “triggers” or home security cameras can even be monitored using 3G or 4G smartphones. Also, depending on the manufacturer and type, the cameras can even be controlled remotely over the internet. For example, a Pan-Tilt-Zoom (PTZ) camera can be controlled remotely from thousands of miles away to move or zoom in on objects.

Regardless of which method you choose, web based wireless camera home security is easy to install and economically priced for just about any budget.

Wireless Home Security Cameras and Monitors

Wednesday, August 18th, 2010

Providing your own home security in the form of digital video camera systems is becoming one of the most popular methods of residential security and monitoring. In addition, wireless home security cameras and monitors are become increasingly popular as well because of their versatility in application, ease of installation and operation, and reasonable pricing that makes them affordable for almost any budget.

What is the difference between “wired” and wireless home security cameras and monitors? Basically, “wired” digital video home security cameras use some sort of cable, usually an RG-59 coaxial cable to transmit their video signals to the monitors and/or Digital Video Recorders or DVRs. This cable is similar to the same cable used by most cable television companies. Although professional installers normally mount the cameras and run the cables using the least obvious arrangements, some homeowners may find the cables a bit too obtrusive, especially if they install the cameras themselves and use a different method.

Visibility of the cable isn’t the only reason for using wireless home security cameras and monitors. Sometimes it may be necessary to mount digital video security cameras in locations that may be difficult to provide cable to or in areas that are so far apart that it is easier to use a wireless system instead. For example, many complete home camera systems are used in rural homes that may contain lots of acreage and additional detached buildings such as garages, shops, or barns. If these buildings are located a significant distance from the home, cabling may seem impractical so a wire home security digital video camera is used instead.

One specific application of wireless security cameras and monitors is when they are used as baby monitors. Wireless digital video cameras can provide you with the peace of mind of monitoring your baby 24/7 and make great baby monitors. The digital video camera that is used for this purpose is usually a wireless night vision infrared camera and monitor system.

Infrared cameras used as wireless home security cameras and monitors, especially as baby monitors, are extremely popular and useful. The camera contains one of two special electronic sensor chips, known as a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These chips are sensitive to infrared radiation in the near infrared spectrum. This infrared radiation or “light” can be seen by the sensor chip (and therefore the camera) but cannot be seen by human eyes. That’s why infrared digital video cameras make great baby cams!

Infrared wireless home security cameras normally have an array of infrared Light Emitting Diodes or LEDs that surround the camera lens or are located somewhere near the camera lens and are pointed in the same direction. These LEDs bathe the target area with infrared light (in this case a baby crib for example) but this light does not disturb the baby because the baby cannot see it.

Often times these baby monitor systems are wireless home security cameras and monitors. The signal is sent using by the camera using radio waves to the monitor. Since the monitor is not connected by any type of cable it can be conveniently moved from room to room to maintain surveillance of the baby.

Remember, wireless home security cameras and monitors are not restricted to use as baby monitors only. These cameras and monitors are great for many different types of applications where a wireless camera and monitor would by useful.

Wireless home security cameras can be purchased with almost any feature or additional option that is available for their “wired” counterparts. Some of these features include: cameras for outdoor use or indoor use; cameras that can record audio as well as video; cameras that have Pan-Tilt-Zoom or PTZ functions to increase their field of view; day/night vision cameras; several different camera types or shapes such as box, bullet, and dome cameras; and even cameras that can be networked using the internet (called Internet Protocol ready or IP ready cameras).
