Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.

Expert:  Rusty replied 1 month ago.

Can you verify that the splitter works? I agree this is the right technology for the job, you did well there. I just want to make sure there isn't a fault in equipment because you seem to have the knowledge to connect this properly, as well as have the right equipment for the job.

Both are brand new no output at all

Ok, a few questions about the splitter...

Is the power light on?

Is the input in the right position?

Does the camera work when connected directly to the DVR (without the splitter)?

Good questions...Is the power light on? YESIs the input in the right position? YESDoes the camera work when connected directly to the DVR (without the splitter)? YES
Expert:  Rusty replied 1 month ago.

Then you have a bad splitter. If the length of cable is short after the splitter, I recommend a passive splitter, click here. You will most likely need the coupler, click here for that.

I will try that splitter i have the coupler...
Expert:  Rusty replied 1 month ago.

If it's working when you plug directly into the DVR, that means the signal is good. Since the signal is disrupted at the splitter, that tells me that it amplifies the signal beyond the DVR's capacity, so a passive splitter will knock that signal down to the proper decibel range for the DVR.

Should I use both amplifier and the passive splitter? I did see one that has gain control...
Expert:  Rusty replied 1 month ago.

No, just the passive splitter. The one with gain control will allow you to adjust it for the best signal. However since it's digital, it will not give you better quality. It will only go from good picture, to a tiling picture, to no picture depending on where you set the gain. If the DVR is less than 20 feet from the splitter, the passive one should work just fine.

The DVR will be 2 feel from the splitter I am going to try and rig some adapters for F connector to BNC that should work
Expert:  Rusty replied 1 month ago.

F connectors, RCA connectors and BNC connectors all carry the exact same type of signal. You can use any of them to adapt to your needs, they all work the same way. The only difference is how far the signal will carry on the different types of cables. You can adapt them how you wish.

sir will try and see what I come up with
Expert:  Rusty replied 1 month ago.

Let me know how it works! I used to build video conferences and cable TV systems, so I'm very familiar with this stuff. I'm here in case you have any questions.

Customer: replied 1 month ago.
Ok instead of waiting for a splitter i will try and put that second connection in the screw on BNC balun that should work correct?
Expert:  Rusty replied 1 month ago.

Yes, you can adapt the BNC to F or RCA as many times as is necessary.
