whitemotel 0 Posted June 9, 2008 hello... i have the altronix altv2416ul power supply (see picture)...i was testing it to make sure it works...so i plugged the wires in and plugged it to my bullet cam....once i powered it up, the bullet cam started smoking...i assume i lost a bullet cam...is this power supply to powerful?...im assuming P and N stands for positive and neutral ...i think i might have put the white/black wire on N and put the black wire on P...will that mess it up?? thanks in advance Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 The altv2416ul is a 24V AC power supply and the Bullet Camera you hooked up to it might be a 12V DC Camera. Post the model of the camera you used. And yes the P & N Stands for positive and negative. Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 i have a no name brand camera...but the manual says: accepts DC 12V/AC 24V Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 If that's the case I don't see any problem. AC wiring is non polarity sensitive. Check the cameras manual and make sure the camera auto negotiates between AD/DC Voltage, either way it should show you the wiring scheme. Most Bullet camera's are DC, the manual maybe for various models, make sure the specs apply to your model. Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 ok...ill give it a try ...i dont want to burn out another camera...thanks again! Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 also, on the 2 prong plug i attached to the power supply, white is positive and black is negative? will that make a difference? Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 also, on the 2 prong plug i attached to the power supply, white is positive and black is negative? will that make a difference? Are you refering to the power cord that supplies power to the power supply? Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 no, i had to get one from lowes and attach from the wires from the power supply Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 no, i had to get one from lowes and attach from the wires from the power supply I'm not sure what you talking about. Give me a part #. If it's the plug to connect the power supply to the camera, then if will not matter which line is used since you are using AC power. Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 i took a picture of it... from that picture you will see the plug i got from lowes.... also, should i use a 3 prong and attach the ground cable to it? Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 i took a picture of it... from that picture you will see the plug i got from lowes.... also, should i use a 3 prong and attach the ground cable to it? This plug is for suppling the power supply with power from a regular 110/120V AC outlet. Yes you should add a ground from the power outlet to the power supply.

whitemotel 0 Posted June 9, 2008 ok..coo.. one more thing, is white positive and black negative? Share this post Link to post Share on other sites
coolie11 0 Posted June 9, 2008 ok..coo.. one more thing, is white positive and black negative? There is no polarity for AC power. Share this post Link to post Share on other sites
C7 in CA 0 Posted June 9, 2008 also, on the 2 prong plug i attached to the power supply, white is positive and black is negative? will that make a difference? Technically no, well I mean it does matter but should work either way. Best practice would be to land the black wire on the hot and white wire on the neutral green wire on the ground. Usually the brass colored screw on your plug is hot and the silver colored screw is neutral and green screw is ground. (Yes attach the ground too) I would get a 3 prong plug that has the cord already attached. Then you just make the connections inside the power supply. I'm not really liking the look of that plug attached to individual wires like that. It is probably a code violation too. At a minimum at least wrap those wires in a spiral fashion with electrical tape. (But I'd get the other cord type.) Share this post Link to post Share on other sites
whitemotel 0 Posted June 9, 2008 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? Share this post Link to post Share on other sites
DVR MAN 0 Posted June 10, 2008 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! Share this post Link to post Share on other sites
cachecreekcctv 0 Posted June 10, 2008 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.

whitemotel 0 Posted June 10, 2008 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?

whitemotel 0 Posted June 11, 2008 well...two cameras gone...one left....tried to hook up the camera again to the power supply....its zapped it.....either i have a really cheap camera or my power supply is pushing too much power Share this post Link to post Share on other sites
coolie11 0 Posted June 11, 2008 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/ Share this post Link to post Share on other sites

coolie11 0 Posted June 11, 2008 If this is the camera "Bullet Miniature Camera(TS-1822)" Sorry to say, You did fry them. The specs clearly state's Power supply: 12V DC, ¡À10% and 120mA Share this post Link to post Share on other sites
coolie11 0 Posted June 11, 2008 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. Share this post Link to post Share on other sites
