these can be picked up for not a lot of cash as I found out when looking at home brewed night vision setups ...... not sure about the distance it could work over though

Good thought I-K-E

It makes the system more complex but might be feasible

Adding to the complexity, its possible to modilate a laser by ausio frequency, and to capture the signal with a photo-diode over ranges of up to 4 miles.
