The cellular service where I want to use them is not the best.
Most cell cams pick up better cell signals than most cell phones.
If you have marginal service on your phone, you should be ok with a cell cam
utilizing the same cell tower(s) as your phone.
I often find that an area has both Verizon & AT&T cell services. It's been my experience that most rural TN areas have better service with AT&T.
Most cell cams (with an antennae) allow you the option to very simply replace that antennae with an auxiliary antennae (which is typically a wire to run the antennae higher up for better reception). In areas of very poor cell service, I sometimes run an auxiliary antennae several feet higher than the cam.
I've tried many different cell cam brands.
For me, I've been overall happiest with Ridgetecs & Brownings.
Most brands work, some just work better, some are a better value than others.
One of the most overlooked "costs" is battery life, and just how many batteries a particular cell cam utilizes to operate. I don't plan to ever buy another one that requires 12 AA batteries.
I have various 8-battery Browning cell cams that will run around a year continuously (I'm very happy with that), and some other brands which die every 2 to 4 months using 12 batteries. And I'm talking Energizer Lithium batteries.
As some of my other brand cell cams die, they're being replaced mostly with Ridgetecs, which for most my uses, are the closest thing to a Reconyx, without the Reconyx price. That said, the Ridgetecs don't have near the battery life of the Brownings, and I suspect most users would be happier with the overall value (and working longevity) of the Brownings.
Call me biased, but I have personally been disappointed with Tactacams, while other users think they're the best cell cams since sliced bread. The are usually slightly cheaper at the point of purchase, but mine have all eaten batteries (12 at a time), while under-performing compared to Browning or Ridgetec.
Understand, most of my more recent cell cam experiences (past 3 yrs) have been with mainly these 3 brands, after having various "duds" with other brands.
