At the rate copper keeps going up this purchase could be more of an investment than a material requirement. This is good heavy gauge copper wire, 2 stranded 18 gauge. It's good for low voltage devices whether they are power by DC or AC power supplies. Of course it has many other uses as well. One particularly nice feature about this wire is that it is on a spool so for long wire runs it is easy to dispense. If you are planning on pulling this, such as fishing walls, etc. you may want to consider an easy pull type kind of wire instead. Also, order this with your other supplies and equipment and if it totals over $500, the shipping is free.

This is good quality, multipurpose wire. I wouldn't have bought it unless my order was over $500 though because if I would have had to pay shipping I could get it cheaper at Lowes (well depending if the price of copper keeps increasing).

Very good Wire! Great for long runs especially inside large rooms (auditoriums, gymnasiums, etc.) or outside as well. Not so great for short runs as easy feed cable, because remember, it's on a spool.

Good quality, proper gauge DC or AC power wire. Use this for extra cable needs like illuminators, special power supply locations, or wherever a Siamese cable isn't appropriate.

I have quite a large area to cover with my digital video security camera system. Several of my cameras are outside and cover the entire perimeter of the house and property. To of my cameras are battery operated wireless cameras. To make the video imges standout for these and other cameras I have purchased a couple of your Infrared illuminators. I use this cable to supply power to the illuminators. The cable is rugged yet pliable and easy to work with. I have seen other Web sites that are asking as much as $130 for the same product.
