This is my most used, favorite camera in the network. Granted, it's for residential security, but I've had suspects change course and leave when spotting the PTZ (especially if close enough to see the lense following them). It's perfect for capturing not only close up's of license plates (our plate reader does this well, too) but often times it helps to capture who is driving with clear usable footage. It's not used to surveil residents beyond incidentally capturing movements, but we're a small community that's close to a university and several homeless encampments. Criminal activity was on the uptick here and getting a solid camera network has proven to be invaluable to us. The last mail thief this prior summer never returned nor has much else happened since we were able to post high definition photos of the suspect and vehicle he used (it was found shortly after thanks to the usable footage and was a stolen vehicle, of course).
We also looked at Axis cameras, but found these to be of the quality we needed without a huge price tag. No regrets with any camera from this company. The installers also spoke highly of this brand almost suggesting they are TOO good for what we needed! Originally a neighbor had a no name Amazon ptz and it's night and day in the quality and reliability and usability of images and video. We also pay for gigaband internet for these, which makes for excellent real-time tracking footage and video.
