When It's set and done -- about $400-$500.
I still need to package this in ammo cases.
I want to purchase 2 new car batteries -- one on each end.
A power switch, some fuses, different cameras (1 up close and 1 set further back). With 2 or more cameras I'll also need PoE network switch and 12to48VDC converter.
I might duplicate target setup for a few different distances. That way I can have it set at 1,000, 900 & 800 or 700.
Or, I might do something like this on the remote end: [Link: amazon.com]


For now, this is what I got:
$65 for 2 antennas, although I made a mistake as I was really trying to buy the M5s.

$53 for 2 Tycon Systems TP-DCDC-1224 Power Over Ethernet Injector
[Link: ebay.com]

~$100 for PoE camera that I used for testing only

Free, old ass Netgear WiFi router (not pictured) that just so happen to use 12VDC as input.

Few battery clamps laying around from BatteryTender kits I buy.
Some 22/2 & 22/4 security wire. Few Cat5e patch cables.
The whole thing works with the camera's (HikVision in my test) software on my phone or laptop.
