I have a Swann NVR8-7200 with the 4 cameras that came with it, with an internal 2T HD. I have the system FINALLY to send smtp email alerts on motion settings after playing around with it. Well now I am getting emails every few minutes. I have turned my sensitive down to 0, but at night the flying insects will go off and send email alerts to me. If I turn it to -1, it won't pick up anything at all, our cars has been getting broke into at night so I would like to know what goes on in the driveway. I guess I should turn off the email system at night, but continue recording motion. Is there any other workarounds? I am having a hard time trying to figure out how to get it to record 24/7. So I can go back and review if I decide to turn off the email alerts at night time. Would that be under Remote Playback window? What am I doing wrong? What are some tips and tricks I need to know. I only had the system installed for a week and keep on learning things about it.

Ok, I figured out that I didn't have LOCAL RECORDING checked. I thought LOCAL RECORDING was meant if the camera itself had internal HD/SD and remote was my NVR. I was wrong.. That part is now solved. Like I said, the more I play with it the more I learn.
