Re: [TSCM-L] {1656} Re: Infrared transmitters
I guess I have to ask why that would be. Is there some advantage to h=
ave considerably (500 times) less amplification of light?
I look at it as a worse case IR laser being used. If you are not in a=
direct line you may not see it with Gen 1. With Gen 3 + you can see =
the scatter as it passess through a window.
Please explain.

We had about 45 minutes of audio on the recorder but it wa=

n the physical search however. These things are available from various manu=
facturers.

Part of my procedure is to take a walk aroud=
the facility and look for IR with Gen 3 night vision. IR comes acros=
s like a flashlight and is easy to see.
If there was a recording (audio) from a vehicle for a day or even a few hou=
rs, how long would it take to download the data using light? It would=
seem that you might have to wait for stalled traffic.

I found a digital audio rec=

the output of the recorder was sent to an IR transmitter, also in the assem=
bly, allowing the recorder to be downloaded via the IR link. The device hel=

off-line unless someone else is interested.
