I am new to survellience cameras and am considering buying a couple of Hikvision DS-2DE4A425IW-DE Outdoor PTZ Network Dome cameras. If the camera needs to pan a couple of times each minute, how long will the motor mechanism hold up? I don't want to go the PTZ approach if the motor mechanism will only last a couple of years. Also, I am able to flush mount to very sturdy soffit, does the camera come with the hardware necessary for a simple overhead mounting (no telescoping required). Thank you.
