When it comes to selecting the best camera systems for farms, there are several important factors to consider. First, the type of cameras used should be suitable for the environment; meaning they need to be able to withstand weather conditions such as rain, wind and snow. Additionally, you’ll want a system that offers night vision capabilities in order to monitor your property even when it’s dark. Finally, you may also want features like motion detection or remote viewing so that you can keep an eye on things from anywhere with an internet connection. Some great options include Lorex's 8-channel 4K security system and Swann Security's Outdoor Bullet Surveillance Cameras which both offer reliable performance and easy installation.
