One of the most popular security devices being used today is the wireless security camera with DVR recorder (Digital Video Recorder).Since the camera is wireless, this means no cables are needed to connect the camera with the recorder, making installation quick and easy. In addition to the wireless feature, a wireless security camera with DVR recorder system has plenty of optional features that make this an incredibly versatile system that can be used for almost any application.

A wireless security camera with DVR recorder is often the choice for do-it-yourself security and surveillance systems because of the ease of installation. Normally, a digital video camera requires to wire hookups. The first is a video transmission cable, usually RG-59 coaxial cable, that must be installed from each individual camera to the DVR. The second wire hookup is a low-voltage DC power supply wire which comes from either a power distribution center box or a plug-in transformer.

If you are planning on installing the system yourself (and many customers do) running the RG-59 coaxial cable can sometimes be an overwhelming task. Installing ...
... the cable requires the proper tools and accessories that average homeowners may not own. For example, holes may need to be drilled through walls and average size drill bits arent long enough to accomplish this task. However, specialized extended length bits make this task a snap. Wall clamps and mounting hardware may be needed as well.

Although the RG-59 coaxial cable is relatively small, some home and business owners alike may find the appearance of this cable objectionable. It requires some experience and construction know-how to install this cable neatly, safely, and in such a way that it is hidden.

The same situations may also apply to the power supply wire although this wire is much smaller than the RG-59 coaxial cable. The power supply wire may be placed in the same run as the coaxial cable if a power distribution center box is used. If a plug-in transformer is used the run of the wire is often much shorter than that of the coaxial cable as the closest outlet is often used.

Nonetheless, the wireless security camera with DVR recorder is a much easier installation. First, there is no RG-59 coaxial cable that needs to be run from the camera to the DVR. Second, often times these cameras come with rechargeable batteries eliminating the power supply wire. The installation of a wireless camera with rechargeable batteries for a power supply is basically just attaching the camera mount to the surface where the camera will be placed.

A wireless security camera with DVR recorder sends its video data via radio waves instead of a coaxial transmission cable. The camera contains a built-in transmitter and antenna that sends the video data via radio waves to a corresponding receiver. The receiver converts the signals back into electronic data and sends it to the nearby DVR via a connection cable. There are many different types of signal architectures but probably the most common is the 2.4 or 5.8 GHz band technology. This is the same technology used for land-line based wireless telephones.

Wireless receivers are able to handle inputs from more than one camera at a time. In fact there are several variations on the number of camera inputs but the most common are 1, 4, or 8. If the security system requires more cameras than what the receiver can provide, additional receivers can be used provided they have different frequencies available for each additional camera and the DVR is designed for the number of cameras used. (Systems requiring a number of camera inputs greater than the capacity of the DVR simply use additional DVRs.)

Wireless transmission technology is based on Line of Sight or LOS. This means that the specified range of the wireless camera is based on a situation where the camera antenna has a direct Line Of Sight to the receivers antenna. In other words, this maximum distance is based on no objects impeding the LOS between the two. If an object does exist between the two it doesnt necessarily mean that the camera and receiver wont work. In fact, usually the object just reduces the range. The amount of the reduction is based on the type of object or material that impedes the LOS (such as a window, wall, trees, etc.).

So if you are looking for an easy do-it-yourself installation but versatile in application system, a wireless security camera with DVR recorder is the perfect solution for you.
