THESE ARE ABSOLUTELY GREAT FOR WATCHING THE HORSES
We can watch the stalls with these great little cameras. They work at night in black and white with just a 7.5 watt nightlite and the picture is just like daytime and have audio as well. Simply connect the camera cable (65') to coaxial cable from the barn to the house and plug into the TV. These start at just $139.

We also have color cameras but the nightvision is not as clear and requires more light. We also have systems that can operate up to 8 cameras on a rotating basis.

For a bit more money, we have some wireless systems that can operate up to 300 feet with either battery or DC current. These come with 1 camera and the receiver connects to the TV.
There is also a complete system with 4 cameras and monitor (14" or 17") all wireless. These show all four cameras in rotation as well as all together on a quad screen.

We also have a terrific little guy - wireless B&W on either DC electric or regular batteries. This unit consists of 1 B&W camera and a 5.5inch monitor. These can be fitted with up to 4 cameras and have a range of 300'. We use one in the farthest barn and the metal roof etc have no effect on the clarity. We hooked one up in the truck and trailer and they work fine off the 12 volt system. under $200.
I tried many systems to see what works the best. The black and white systems really are the best for night vision and with almost no light (7 watt bulb) the stall looks like midday. However, I do have most of this setup and ironed out the bugs as to what works best with horses and foaling. Feel free to call or email with any questions.
