I'm all about the solar charged cellular system now. It's like power windows on a car - I'll never go back to hand crank.

One advantage is that I'll leave the solar camera active throughout the year. On batteries, I usually set out the cameras before deer hunting season and still need to change out the batteries before the end. Post season I'd let the batteries run out and then I collect the devices for the year. It's not worth it to me to feed batteries to multiple devices throughout the entire year.

I'm using one now for a security camera on my driveway. It's cellular so I get notified by my phone app that someone has entered my property - with a couple of photos.

Of course, it matters if the camera isn't positioned to get the necessary solar to keep it charged. I try to select locations and face the device south to optimize the charge. In the worst case, the battery dissipates, and you bring it in for an occasional recharge (still less frequent than straight batteries).
