I have several trail cameras including Reconyx but now just use the Covert Black Ops model as it can send images to up to 4 phones and 4 emails. Another camera that is very similar is the HCO Panda. Both cameras take still images and video and can handle up to a 32 GB SD card. I've got some great photos of coyotes checking out the collarum this fall.
What is really nice with the newer Black Ops model and the Panda is that you can dial the camera and take a picture, add/remove a phone number or email, or turn the camera on/off. No having to go and retrieve SD cards or wondering if the SIMM card isn't working or the network is down (e.g., SmartScouter issues). Just text the phone number for the camera and enter the proper numbers to get immediate feedback. Both cameras run around $350 and work off of the AT&T data plans which on the cheap end is $10 for 1000 text or two months (whichever comes first) or you can do unlimited texts for $20 and both plans have autorenew options if you want. Yes, they are a bit more than most trail cameras (except for Reconyx) but if you look at the time savings you get by not having to drive and check traps or pull SD cards from trail cameras to see what you were missing, they end up being cheaper in the long run. I'll be running an article on them shortly in WCT Magazine.
You can get the Covert Black Ops from Wildlife Control Supplies and the HCO Panda from Rob Erickson.
