As another reviewer has mentioned, this unit is designed to be used in a car, since it’s designed for 12 volts DC. (I guess I’m too old for this stuff. As if booming 800W car stereos aren’t enough, are people outfitting their cars with a DVD player for every seat now?) But that doesn’t mean you can’t use it at home as we are.
In our case, we have a home surveillance system using a dedicated DVR. The DVR has baseband (i.e. “video”) output that we send to various LCD monitors throughout the house. It’s a big house with lots of electrical wiring and other signal cables in the attic. We’re using a converter box Kworld 1680EX LCD Tv Tuner Box Support HD 1080I High Quality Image to convert the signal to VGA. Even tho we’re using RG-6 Quad everywhere, after the splitters and all, there was some signal degradation, and I needed an inexpensive baseband amplifier to boost the signal strength. This does the trick!
I don’t know the S/N figures, but it seems clean. You can adjust the output level, which is helpful for good vertical sync. (Install the amp right after the signal source for lowest noise.) I asked our professional installer how much industry amps cost. He said the last one he bought was about $200.
If you don’t have a 12 volt power supply or wall wart handy, you can tap your UPS battery for power. (You are using a UPS on your surveillance system, right?) Inputs and outputs are all RCA, so you may need BNC to RCA adapters in a professional surveillance system….
