Good Evening everyone.

I am touching up an old install that someone else had done awhile back still, and the generic 1.5 year old CCTV Monitor has blown out. No picture at all.

I am trying to get the owner to purchase a new monitor, but doesn't like the cost.

The input to the monitor comes from a Time Lapse Recorded using BNC, a BNC converted goes to coaxial, another BNC converted connected the coax to the monitor.

Would it be possible to use a regular TV with some sort of add-on, since the cabling is coax? I don't think there is, but thought I would ask about it.

thanks.

Same owner, same system, the guy has a GeoVision DVR 16 channel, and would like to upgrade to a true-bred DVR, that can store approximately at least a month.

I figured this would be an easy task, of course, but he doesn't want to spend more than 1k. I found generics for that kind of price, but he figures he could get a cheap name-brand from eBay. That's a no-go, they're still 5k.

Anyone use cheap 16c DVRs?

The only other thing I can think of is getting a 1Terabyte add-on to the GeoVision system, which wouldn't be what he wants, but would get him the 30 days.

Thanks!

Absolutely, a regular tv with a video input would work. If you dont have a vid input use a 75 ohm modulator and set the tv to channel 3 or 4 (usually your options on those devices.

I'll give a modulator a try, thanks!

That BNC out is just composite video, so most TV's now have at least one composite video in. The difference between a regular TV and a CCTV monitor is the resolution though.

Haven't seen any good 16ch for under 1k.

I actually just finished a residential job. I took the s-video signal out from the DVR and ran it to video distribution unit. I then ran it to 4 tv's via an s-video run over cat-3. It worked out well. The DVR I used actually had an s-video output. But the same concept will work fine with composite video.

This is the video distribution unit I used.

Sounds like you have your hands full with this customer.
Go to Wal-mart and buy a combination tv/dvd recorder and install it for him. :rofl:

Seriously, I don't think you are going to find anything with the kind of fire power the customer wants with the price restrictions you are limited to.

Looks like a nice unit anthonyh.

Bobby: I figured as much as that.

Thanks for the input guys! I'm going to give a modulator a try, and see how that turns out.

Do you already have the regular TV and does it not have composite video in?

A modulator is a really bad idea. It will reduce the lines of resolution down to about 240 using the tuner input. The composite input will be closer to 330.

Most cameras are capable of at least 340 with the majority of them in the 420 field.

This is what makes an actual CCTV monitor stand out. It's not uncommon to see them up to 1000 lines.

Video to VGA adapter.

Try one of these and get yourself a dirt cheap 17" PC monitor with a lot higher resolution.

We literally dump about 15 monitors last month, cant even give them away, everyone’s going to flat panels.

It is a 17" regular TV, w/o composite video... We had thought of using a monitor, but the adapting to use one would be upto $90, Since he had a spare TV laying around, it seemed like a good idea...to him.

Even with the compusa adapter, I would have to convert it to composite.

I will bring up your ideas with him either tomorrow/saturday.

Thanks for the help, any others let me know.
