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

Absolutely nothing. They are the same.

Q: 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.

Q: 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.

Very poor packaging

The hard drive is no doubt good. But the delivery package is extremely poor. It's a very delicate item. It is packed in single bubble wrap which is very thin and does not provide any shock to hard drive. This is placed in a thin plastic bag. This is a horrible shipping from the seller.
