Security system

What security system would you recommend for farm animals?

I have a very large farm and it is really hard to keep everything under control, I am very worried about any emergency situation, so I installed hog barn alarm systems . I chose this company because of the fact that this alarm system is wireless and works three years autonomously, and then you just need to buy batteries for $ 2 and easily replace them. So I recommend it to everyone, you can follow my link and cooperate.
