wired vs wireless cameras

[24SecuritySys]

I want to install security cameras in office and am not able to decide whether to use wireless or wired cameras for it, Although I have read few articles about surveillance systems on websites like http://www.24securitysystems.com/home-video-surveillance/
and find it useful
but still this question remains
if anyone know which one better and is willing to share his knowledge
please tell

wired will always be more reliable. you need a power feed to the camera in any case,
