In May, my mare will be giving birth to another foal. I need to find a way to keep an eye on her while I am at my job. Last year I didn't have any luck putting a monitoring system together, so I am turning to you for help. Two years ago, the foal died and the mare almost died due to complications when she was giving birth while I was at work. This is need, not want. My barn is 200 feet from my house so last year I bought an infrared IP camera, a range extender and a wireless router but had no luck. My router would only recognize the camera when it was hardwired in. There is no button on my router to press as their instruction says. My ISP directed me to hardwire it with 250 feet of Cat4 cable and they would not replace the 2011 router. We only have one ISP who serves our area. Any help/guidance would be very helpful. Thanks.
