The Hik 2432 and the Huisun PTZ work well together with the Huisun mounted behind the Hik. The Hik supplies the audio to the Huisun using BI and the Huisun lights up the area with its powerful IR LED's for the Hik. They were meant for each other. 
Here's a comparison with the Huisun IR's turned off in the first capture and with them turned on in the second pic.
