Cuddelink is the most affordable for sure. You have to be able to accept the limitations of that system to be happy with them though. I have had a handful of guys over the years purchase a system after using traditional cellular cams and not been happy in the endI am using three different cellular cameras and testing quality. I am using Spartan, Browning and Tactacam Reveal. The Spartans have incredible quality and reliability but pricey to run. I would like to hear some other opinions on people running 15-20 cameras.
