Andy, the Brownings have much more settings options, and can be changed more easily, more frequently, and more reliably. Right now, I change my Browning settings twice daily (once in the am, and once in the pm). During the rut, I often change settings on particular cell cams several times in 24 hrs. I've not been able to reliably do that with the Tactacams.
Since I'm varying the settings so much on the Brownings, not sure what I've been averaging. But for months, I had one of them beside a Tactacam, and the Browning was transmitting about 500% more pics than the Tactacam, due to it's transmitting 100% instead of 33%, as well as the faster recovery time of the Browning.
Recovery meaning that if the cam was set on 1-minute intervals between triggering events, the Browning might trigger on 5 events in a 6-minute time horizon, while the Tactacam (also set for 1-minute intervals) might trigger only twice in that same 6-minute interval. This is a big difference, and the Browning was getting lots of activity the Tactacam was completely failing to get, not just failing to cellularly transmit (upload).
In all fairness, maybe that particular Tactacam was made on Monday, but the other one I have seems to have similar long recovery times between events.
