"Take photo now" is being removed from the menus for the video-capable cameras but I'm not sure whether that's only in the beta version(s) right now or in the production version.
Direct SMS commands are for the older cameras and I think not for US users, but for people overseas. I'm not sure because I've never used it.
There is no way command any of the new video-capable cameras to take a picture now.
Can you use scheduled event photos to provide you with photos periodically? I do that on all four of my main security cameras even though they are capable of real-time control. I have one of them set to real-time control in case I need to test something in a hurry but I can't remember the last time I used the take a photo command.
