Which HIK NVR to purchase

[mhz 0]

I am currently running 5 x DS-2CD2342WD-I Turret cameras in my home and looking to purchase around 5-7 more of them.

I have been running a PC with milestone software on it but am finding it doesn't really have the grunt to keep up with the recording.

 

I am wondering what HIK NVR's I should look at to run these cameras.

I should point out that I am running the current cameras of a 24 port Cisco POE switch.

 

Any recommendations would be appreciated.
