Wireless Cameras are relatively expensive and are not as reliable as wired systems. Most wireless systems are Line of Sight (LOS). Remember that wireless security cameras require power to operate. So even though by going with a wireless solution you can eliminate the need for coaxial cable for video transmission, you still have to wire the camera to a power source. Keeping that in mind it depends on what you want from your camera. How far away will the camera be from what you are trying to record? Will the Camera be inside or outside? Does it need to record color or can it be in black and white? Do you want to be able to remotely make the camera zoom in or change the viewing angle?
