Wireless CCTV systems utilize wireless transmitters from the camera to the receiver to avoid having to run wires. The ability to transmit video signals without wires can be very convenient for many locations which have limited access or ability to run wires. Wireless technology is developing at a fast pace, but there are problems with it that you might not know about. Wireless in security gives you an opportunity to place cameras just about anywhere you want. Theyíre not limited on where to place them because of other connecting wires that run into your home or business.

The hassle of recharging and putting the batteries back in, scare off most people from ever wanting to invest in a wireless camera like this, so if youíve got the time or someone else to do it, itís a flexible option.

The problem you might find is that if there are any obstructions, it will weaken the signal, and you wonít be able to view what it captures. At times though the signal will be enough to catch blurry images and jumpy screen shots of whatís being transmitted. Youíll have to contend with walls, crevices, and even weather when trying to get clear signals all of the time for security. Donít forget either that youíll have to work around any permanent objects in the way of transmission too, such as trees or utility poles for a home or business security camera. Installation of a wireless security system requires someone thatís trained in the cameras and receivers, and knows the latest tips and tricks on getting one to work properly too. Expect then that your cost will increase with not only installation, but fine tuning it to work properly.

The manufacturers donít really have a standardized encryption for most consumer wireless security cameras.

Wireless CCTV camera systems have a very high Ďcoolnessí factor. A wireless system provides the solution to the problem of signal transmission.
