Well I am sure I am not the only one to run into this, but the threads that came up in my search did not help me much.

I have a client who loves their modulated cameras, and now she loves digital cable...you begin to see the problem.

When I run splitters off the wall jack, one into the cable box, and one into the tv the signal on the analog is really bad, if i put an amp in I loose some of the digital cable channels.

Ideally I would like to put my cameras on four channels, then use the channel 3 output of the digital cable box and combine it with my cameras' modulated signals and program the tv tuner to see only channel 3 and the camera channels, this requires some splitting/combining work that yeilds very poor picture quality all around.

Some of her tv's don't have av inputs, and the guide and digital cable features are more important than picture quality to her (obviously since digital cable looks like crap). I can't run additional wires (old house drywall basement), and satellite is not an option.

What are you guys doing in these situations???

Thanks in advance.

1. Put a low pass filter on the incoming cable, allowing you to modulate above channel 117. Put an amplifier on the cable after the filter.
2. Modulate on 125, 123, 121, and 119 (that might get beat up, but it's what's available).
3. Combine and split as needed to feed each room.
4. At each room, put a two way splitter in place as the coax comes out of the wall
5. Send one lead to cable box, and take A/V out from cable box to A/V in on TV
6. Second leg of splitter to TV. Tune TV to 125,123,121,119.

Customer watches cable on A/V input. Watches cameras on TV tuner.

Good remote control is imperative to make this seamless.

We have spent many hours thinking of solution also. The above post is about it. Modulating cameras is great, except with digital cable! Pain in Butt!

Look for a post about a year old that I asked about this in. I believe the solution was though a company called Eagle. You can call them and they will manufacture you a custom notch filter in the rage that the cable company puts their internet signal on.

Run an extra cable to each tv, charge her more money.
put the cable in one of the video inputs make more money...

simple as that...
I do it all the time...

always make more money that way with the digital cable...

Primo's idea is the best way to do it in the ideal world. Of course that's not always possible.

Channel Vison, Channel Plus, and many others all have digital cable box bypass systems available. They work extremely well and all you to do just as said in the earlier post.

"Ideally I would like to put my cameras on four channels, then use the channel 3 output of the digital cable box and combine it with my cameras' modulated signals and program the tv tuner to see only channel 3 and the camera channels."

They free up any and all available channels for modulation that the cable company is not using. This is especially helpfull if there are older TV's that don't have 125 channel tuners in them.

With digital cable you really need to talk to your local cable companies and get them to give you a channel map. With all of the new cable features like video on demand they are using the channel carrier frequencies of the unused channels for return paths. If you modulate a camera onto one of those channels than you will likely lose some of your digital features. Beleive me I've had this problem several times. The worst part is more than likely you won't know about it until Saturday night when the client calls and says they can't do so and so on their cable box.

That said what you want to do is very easy you just have to pay attention to what channels you use for modulation.
