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

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.

i have a no name brand camera...but the manual says:

accepts DC 12V/AC 24V

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.

ok...ill give it a try ...i dont want to burn out another camera...thanks again!

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?

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.

There is no polarity for AC power.

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.

ok..coo..

one more thing, is white positive and black negative?

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.)

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! :shock:

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?

You don't need to. Here's the specs for the unit you're using.

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

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/

Post a picture of your exact hookup.

here is the spec to the camera...

http://www.acesuppliers.com/Supplier_Company/Bullet-Miniature-Camera_Product_Showroom_43077.html

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

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.

damn....check this out....i scanned the manual...i guess the manual gave me the wrong spec...

is there anyway i can use the power supply for that last camera i have?

unable to attach pic...check it out on my webserver: www.beatmanproductions.com/pic.jpg

no, didnt by them on ebay....bought them from a website from china...i sent them an email saying they went bad....they say i have a one year warranty...we will see...

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.

def a learning curve....and def a hobbyist!...got an email from the company i purchased it from they are going to replace it for me...

Now all you need to do is buy conversion transformer for the three 12vdc bullet camera's, they a only around 12 to 14 dollars. That way you use the altronix and when you get ready to upgrade to better cameras you don't have to rewire everything.

Good for you.

You may be able to exchange your power supply for their 12 volt DC supply. If you do, I suggest that you get the fused version, and replace the output fuse for said camera with a fuse that suits that camera. Then if there is a problem, that output will blow the fuse and possibly save the camera. With DC voltage, you must have the ( + ) output going to the plus wire on the camera and the negative wire going to the negative wire on the camera. Usually that means that ( + ) positive goes to the center contact on the camera connector and the ( - ) negative wire goes to the outer connector. Or if there are only wires coming out of the camera, the positive wire should be marked positive. The remaining wire will be ( - ) negative. :)

yo...

i like to, again, thank you guys for the support.....i will def consider everybody's opinion and figure out what will work best....


thanks again! :D

Good Luck ! Remember to use that volt/ohm meter. One of your best "friends" available.

You may decide to go with all 24 volt AC cameras if you cannot return the supply. Good luck!

Thought I'd just in here with a couple of comments.
Yep, those cameras were fried due to AC being supplied to a DC camera. Look on the bright side, you've learned something and loosing those cheap cameras will make the lesson more poignant and the memory last longer. Second, I'm almost certain that the illegible word ¡À10% originally said +/- 10%.

One of my more inexpensive (under $50) model Fluke V/O meters, has an "auto sensing" range on the voltage side. Accurate for low (12 to 120) voltages. Don't use it that often, as most of what I work on is 480 3-phase. I am sure you could find an inexpensive meter at a local Electronics house. The meter would have paid for itself in this case.
