This is one of Dahua’s latest PTZ cameras with IR LEDs and 30X optical zoom. If you have lower zoom needs, the same camera is available with a 12X zoom as the SD59212S-HN. What makes this camera unique from other PTZ as well as other IR PTZ’s from Dahua or Hikvision is that it can tilt up 15 degrees above the horizon. If you have ever owned a PTZ, you know what I mean, very annoying when you can’t see past the horizon. If you compare this to prior IR PTZ’s from Dahua, this one is considerably smaller. What also makes this PTZ unique is the more affordable price.
