Yes, that is possible. I currently have my camera active from 8:00 p.m. to 6:00 a.m. 

Absolutely! The night vision binoculars with infrared aren't just for nighttime use; but also work as a telescope during the day. 

Can be stored but not charged with the original charger 

First, you need to check whether the camera battery is sufficient. When the battery is below 30%, you cannot take pictures at night. You can see the battery in the lower right corner of the camera screen; then format the memory card; find the delay in the menu Take pictures, note that the factory default setting is 30 seconds, but if the animal stays in front of the camera for less than 30 seconds, the picture will not be taken. You can try to set it to 8 seconds, 5 seconds, etc. 

No, you can sling to the front and then you open it, very impressed with this bag.
