Used 4 models of Spypoint, plus tried a couple of the cell units for regular cameras. Their big attraction is the free plan for the first 100 pictures a month, and only $5 for 250, $10/1000, $15 unlimited. They are fussy about signal., cams break easy, glitchy to operate, and customer service SUCKS. Have no Spypoints now.
Was going to try a couple of Tactacam Reveal X 3.0 this year, to run along side the Reconecos as the newest Tactacams don't need and SD card and are about 50 bucks a camera cheaper, $70 with not needing an SD card.
The Reconecos are great cameras, reliable, easy to setup, easy to get signal on, very fast picture transmission and SMS notification, usually within a minute or 2 of the picture being taken. Unlimited plan is $16 a month, cheaper by the year, can cancel any time. Easy on batteries but takes 12 AA. Very good customer support. Only drawback is the cameras are $225 a pop, plus the $20 for the SD card.
Have tried Bushnell, and Browning, sold them all or returned them.
All prices are Canadian dollars.
