What is the difference between 3tb purple wd30purz and wd30purz, very confusing?

Absolutely nothing. They are the same.

Is this compatible with annke surveillance camera system 8ch 1080p lite h.264+ dvr with (8) hd 1080p outdoor weatherproof cameras cctv security camera

As the owner of South Jersey Surveillance Systems, I can assure you that any WD purple or Seagate Skyhawk hard drive is the appropriate type of storage drive for any and all DVRs and NVRs.

Whats the difference between this and the red plus?

WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue. WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap. WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs. WD Red is a NAS drive. It’s optimized for NAS systems. WD Purple is for surveillance. Advised for 24/7 operation. WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.
