Hi, my name is XXXXX XXXXX it would be my pleasure to help with your issue today.

Your cameras connect to your DVR via RG59 Coax. It will depend on how many of the cameras you need to extend the cables on which method you will want to use to extend them. The reason I say this is because of cost.

What you will need to do is figure the total length of all the extensions that you need to determine whether to buy an entire roll of RG59 coax or if you can get away with just buying a 100 foot section that already has the ends on it and just cut it to length.

Here's what you will need to get the job done. I'm not sure what your proximity is to a home improvement store, but most all home improvement stores in the US carry these things.

1. RG59 coax cable. Make sure that you buy cable that has a solid core center conductor and not the cheap stuff that has a twisted copper center core. This will save youa lot of time and heartache when putting on the coax terminations.

2. You will need one BNC to BNC male adapter for each extension to mate the extension cables together. For instance, if you are extending 5 cameras, you will need five of these.

3. You will need two BNC crimp on termination for each of each of your extension cables.

4. You will also need to purchase a BNC crimping tool. YOu can do this with a pair of pliers, but it will make life a lot easier to have the correct tool to crimp on the BNC terminations with, so it will be well worth the cost.

That should be everything you need to extend your cables. If you don't have a home improvement store or electrical supply store locally to purchase these items at and you would like to purchase this equipment off of the internet, let me know how many cameras you need to extend and I'll recommend an online supply house for you that specializes in this type of equipment and make out an order for you for everything that you will need.

What I will need to know is the total length of all the extension cables and how many cameras you need to extend. I work with this stuff every day at my job and can most likely save you some money by buying the equipment you need online if you would like. The only down side to this is that you will have to wait for it to be shipped to you to get the job done.

I'm also familiar with the q-See DVR and can help you with the setup of the DVR to get it working to it's fullest capability, so once we get your extensions done feel free to contact me directly here if you need any assistance with your DVR.
