A little bigger than a coin, but should fit in a barrel.

I did not see any information as to where to access this type of equipment. do you have a source? Please advise. Thanks

Maybe a lojack system, or how about just installing video cameras?

These are containers in multiple locations collecting waste oil and other products too many I suggest for cameras plus you have to get a good photo for police to act. The product is not too pricy but the containers are worth quite a bit. Thanks

How about a dog or child tracking device? Look here.

Or maybe an FM transmitter found here.

Getting closer to finding something in Trimble TrimTrack

I have needed something like this a few times myself, and that's why I've gone to so much trouble to find something.

later . . .

Let the hippies have their grease Just have a drop-off for the containers

Tape a cell phone to the side, then go to that web site that will show you where a particular cell phone is in any part of the World. It's a new service.

Check the Yellow Pages for security companies. Most will be able to direct you to one that deals in this product.

Or, Google "Canadian Society for Industrial Security, Inc." for contact coordinates. Head Office will direct you to a security company in your area that deals in this product.

Tracking systems are wide spread now and are a key security measure.

Cheers.

By the way, what is in these barrels that's so interesting that the get stolen? Hum?

Waste Vegetable oil. The container is worth more than the oil and the container goes missing also.

Paint a sign on the barrels.

FEEL FREE TO TAKE THE OIL BUT PLEASE LEAVE THE BARREL.

THANK YOU.

or

PLEASE RETURN EMPTY BARRELS WHEN FINISHED.

What a cool thought. Hmmm, ...yeah, only thing I can think of is a dog homing device. About $450. ea.

It's a tricky problem, because to be effective you'd need a tracking device on every barrel - that could add up pretty quick.

The most inexpensive beacon type FM tracking transmitter I found was the Beeline at $59 apiece, unless you make them yourself. They also don't look too easy to hide on the surface of a barrel, and I don't know how well they would survive being immersed in oil.

If the barrels were really worth a lot, you might get a more cost effective and lower profile solution by going to a supplier of GPS chips or modules like linx. to get a wholesale deal and customize your tracker.

RFID is a less expensive system, pretty low profile: the least expensive tags are around $20 each, and the systems have half decent capabilities for a security system, check out these affordable systems. The upper limit on range is about 300 feet so it's no GPS, but you can design a useful security system all the same.

Excuse me, but why all the effort of tracking... Can't you and a few of your friends hide out one night with baseball bats, and just citizens-arrest the perp?!

OK, I'll concede this... Drive really long nails through the bats before you and your mates go out. And by the way, there's nothing wrong or illegal about a citizen's arrest.

Just like a police officer, he's allowed to use whatever force is necessary to apprehend a person in the act of committing a crime.

OK, so why not just paint a skull and cross-bones on the side of the drums, with some sort of wording regarding it's carcinogenic properties. That should make them pass it up.

yes, painting the drums, IMO, is a cheaper idea. something that looks like this, too.

BTW, thanks for the GA.

Put a radiation symbol on a container and you will have more problems than you could EVER deal with ............. at least in my area of the planet ( NE USA ) however an Improvised Explosive Device may be a viable option.
