Do you have an option for images? I have a location in mind that spans a shed to the barn with no trees that trigger motion,
Camera motion detection isn't all that great outdoors. It doesn't even take the wind or trees to trigger a motion alert. Camera motion detection works by detecting changes in the colors of the pixels, not actual movement. Just the shadows off the clouds passing by the sun is enough to trigger the motion detection on a camera.
Most of the traditional game cameras have a separate built in motion detector that triggers the camera part of the unit.
I use Vivotek cameras at my place. I have SD cards inside them to record the most recent events, I have them connected to my network where I have network attached storage for all the cameras to record for long periods, and I run a Cradlepoint Mobile Broadband Router that I plug a USB AT&T 4G LTE Modem into for internet access over my standard cellular account.
Cellular abilities built into the camera is nice for one camera, but once you start getting a bunch of cameras it can get expensive fast. SMS is essentially a very limited form of email (which is why you can email from a PC to text message on phones by using email addresses such as
1234567890@txt.att.net; with 1234567890 being the phone number, and it works on all carriers by changing the domain name). The Vivotek cameras I use can be set to email on alerts (could be set to email to your phone's SMS), and with email not being as limited you can send yourself better resolution images.
I've found the Vivotek cams to be the most versatile. With the internal SD recording, NAS recording, built in webserver, ability to database all the video on a network server, ability to send a wide variety of alerts, awesome software works on all versions of Windows PCs, has Android & IOS apps, they're able to do almost anything someone wants. With some creative implementations of wireless access points, wireless Ethernet adapters, powerline network adapters, power over Ethernet adapters, and standard Ethernet, there really aren't many installations that can't be made pretty easy.
