We retired and are gonna travel a little more in our camper.  I have a guy that will check cows and calve daily on grass and stalks but I was thinking about putting a game camera on the automatic waterer (12 foot tank) and on the two electric fence chargers.  The chargers have a screen that shows how many volts so you can look at the charger monitor and tell if there is a short.  Just for my well being...

The stock tank will be outdoors and the one on the chargers is indoors.  What brands to avoid etc....   Verizon will be the carrier.   Thanks in advance!!!
