sweet....ill def do that....
you guys have been a great help.......
oh yeah, does anybody know why my bullet camera fried when i plugged it in? |
I bet that if you read the install manual, you will see 12 to 24 Volt DC !
I have seen 12-24 volt AC cameras. I have seen 12 Volt DC, or 24 Volt AC. I have also seen cameras state 12-24 volt DC in spec's, then when you read the whole manual you may find that that particular model is only 12 OR 24 volt DC. Please check before smoking another camera. Good luck!

I normally use the same 2.1mm connector to power up either 24vac or 12vdc cameras. On the box-type cameras, I put the pigtail end on the camera. I ALWAYS hang my Fluke Voltohmeter right next to the camera , and check incoming voltage before putting camera to the test. On 12vdc cameras, the center of the plug is always "positive" DC. My Fluke is a model 322, which has a "clamp around" feature, for when I am checking amp draw. The clamping feature works on just about anything to hold it while I read the display.

yeah, i actually read the manual, but not too familiar with "power"...the manual says accepts DC 12V/AC 24V......but something went wrong with i powered it up to the power supply.....
i do have a multimeter but dont have a manual for it.....its a greenlee digital multimeter...can i test the volts or whatever to see if its really 12 volts of power the power supply is pushing out?

Dude post the model of your camera, or the exact specs.
Scan and post the spec sheet.
Provide a link to the product info.
I'm truly believing you have DC Cameras not AC/DC Cameras/

I'm sure these use a 3.5mm plug for power, which is used by most DC Cameras.
And I sure hope you didn't buy them from flebay.

As an installer, you really need to get familiar with the volt/ohm meter. Probably the most used troublsehooting device. Voltage and resistance/continuity make a big difference in any installation.

Power supplies do not "push" out amperage. Your devices (cameras, DVR's, etc) "draw " amperage. Again, amperage is based on resistance. I always try to use the largest ( in terms of VA) power supplies. VA= Volt Amperes. Motors, lights,coils, etc. etc, use different amperage (current) based on this resistance. Don't purchase cheap meters. Buy one decent volt/ohm meter that will last you a lifetime.

If that is the manual that came with that camera, then something went wrong some where.
That manual is far a Box/Brick type camera like the one below.
The camera you provided the link to would of had to look something like the bullet .jpg.
Hope your warranty works out.
Are you an installer, or hobbyist.
I suggest you make this site and google your personal friends, and use all the spare time you have to read, read, read,.
Don't be disappointed we all went through some sort of setback at start up.
