If you've been waiting for an HD-CVI technology PTZ Camera that would do everything you want then the wait is over! This PTZ has an amazing 30X Optical Zoom that goes from 4.3-129 mm so when you need detail, imagine what you'll be able to see! Remember that an HD-CVI Camera MUST be used with an HD-CVI compatible DVR. If you're adding on to an existing security system that already has a CVI DVR, you'll be fine but if you are upgrading from Analog, I suggest you check out our Tribrids so that you have some flexibility. If you don't have any experience with CVI technology, you should get familiar with it! People love it because they can save a ton of money by not having to run all new cabling thoughout the building. That's because HD-CVI uses a standard coaxial cable that transmits Video, Audio and allows you to control the PTZ over the same cable!
