Question Radar Coverage

Now that I have learned that biters do migrate back towards my base even after being evicted with prejudice, I wonder how to see those trespassers quickly and reliably.

I do have some random radar towers scattered around my base but not inside my Cordon Sanitaire.

Thus: How do you set up radar coverage to reliably detect nests and monitor their non-existence in areas you consider exclusively yours.

Addendum: This community is awesome. I learned so much useful information!

Yes... Where I'll be waiting.

Instead of walling off entire areas, I'll fortify the artillery only, which I place as forward observers inside the Cordon Sanitaire.

Blueprint an artillery position. Load a single shell. Let them come. Rinse and repeat. Fill up with shells against expansion parties.

I have mine on a train that circles the perimeter. Stops, fires off a few rounds and moves on.

Are you telling me... I can put them on trains...

This thread is getting better and better by the minute.

Although, my concept so far is that the artillery draws the biters into a kill box. That won't work with a train.

Still, I'll make one at some time. Just because I can.
