Security Cameras: Tips Needed

The price all depends on what you what and/or need

For example:
number of cameras, vandal resistance-ness, exposed wiring vs concealed wiring, color or black and white, zoom capable, recording or not recording, quality of image, camera in elevator or not

Plus many management firms mark-up the price a contractor gives.

I lost a big camera job once using high quality stuff. The co-op board gave the job to someone cheaper who used cheaper equipment and six months after the installation was complete, the board was unsatisfied with the quality and paid the SAME contractor more mony to install what I originally proposed: the end result is it cost them more than my original price.
