Cancel Alarm System But Keep Cameras Active?

I am a current Digital Life Customer but want to downgrade my plan. I currently have this plan: Smart Security. It includes security/alarm monitoring for $39.99 and then a Garage Door Package for $4.99 and a thermostat $4.99 and Camera package $4.99. Can I drop any of these? I no longer need or want the Garage Door and thermostat package and want to get rid or downgrade my alarm system- I don't use it. Really I just want the cameras and the absolute minimum system service package until I can find someone else since Digital Life is going away. What are my options?
