Is this a good camera?

Annke, made by Hikvision is a reputable company. To use that camera at night and in color mode the LED lights are going to attract a lot of attention if you have neighbors within 1/2 mile. If you use the IR lighting at night you will not attract attention. You can get a camera with near the same specs, 4mp, 25X, 1/1.8 sensor for MUCH less.
Here is one from EmpireTech that has those specs for $500 cheaper.

If you are not a night owl then this is a fantastic 25X PTZ which I highly recomend.
 
Thanks, I really would like a 4K camera. I wonder how bright LED lights would be at night? This camera has an impressive 1.8 sensor. This is probably fantasyland anyways but I was just doing some research.
 
1/1.8 sensor is a great sensor, for 4MP cameras its ideal. For 4K as we've found, its still not optimal.

Dahua makes two 4K cameras (a turret and bullet version) with a 1/1.2" sensor that is impressive
