mikeygt350 0 Posted May 15, 2009 Does a power supply usually come with higher end cameras or not? Say $400 plus? Also, is there usually just two wires for the power connection, as oppposed to a center pin connection or something else? Share this post Link to post Share on other sites
Soundy 1 Posted May 15, 2009 Does a power supply usually come with higher end cameras or not? Say $400 plus? No, because they're used mostly in installations with one central power supply. Your average integrator/installer wouldn't want to pay extra with the camera for a single power supply when there may be more than a dozen cameras to install... not to mention then needing to find somewhere to plug them all in (since such a supply is usually a "wall-wart" style, that means a LOT of power bars). Typically the only cameras you'll find that include power supplies are the cheap-cheap 12V ones intended for hobbyist or DIY home users. Also, is there usually just two wires for the power connection, as oppposed to a center pin connection or something else? Generally, yes, there are just two wires, whether it's 12VDC or 24VAC or anything else. Some cameras include a ground terminal as well, but I've never used that personally (I know there are some instances where you would). Share this post Link to post Share on other sites
