NVR: http://www1.hikvision.com/cn/prgs_679_i4418.html
Camera: http://www1.hikvision.com/cn/prgs_191_i7025.html

Although is wireless, you will still need to provide power point at the location of the camera.

The NVR specification stated that the total max recording bandwidth is 25 Mbps.
The camera, each can supply max of 8 Mbps, 4 of them will be 32 Mbps, which exceed the total max bandwidth of the NVR.
You might need to cap the max bandwidth for each camera to 6 Mbps, should be available in the settings inside NVR.

Tip #1: Avoid bundle hard disk together, reason is chances are the hard disk might suffer damage during shipping from China to Malaysia. You can get the surveillance hard disk like Western Digital Purple in Malaysia, and then install the hard disk yourself.

Tip #2: Since you planned to get the whole set of CCTV solution from China, your parcel might subject to GST, since the total amount of the parcel import is more than RM 500.

If you are buying from China, especially any electronics with software required.

In your case, IP cameras will have its own user interface, you'll need to login to the IP camera and do some basic settings, such as:

1. IP configuration
2. Motion, or continuous recording setting
3. Memory card formatting (there should be a setting in the UI as well)
4. Encoding setting for resolution and frame rate

Most likely, China products do not come with English firmware, unless you're comfortable with Chinese firmware, then please take note. Hmm, also there's a way that could possibly update the firmware from Chinese to English but it comes with great learning curve and lots of time as well. Not to mention that there's always a risk in cross updating different firmware language. Worse to worst, you might end up with some gibberish language mixed up.

Hmm, from what I remember the firmware usually comes exclusive. Yes, the device does support both languages. However, when shipped to their dealers, in order to protect all dealers, manufacturers prepare chinese language for china market and english for overseas. Therefore, Chinese dealers won't be able to disrupt overseas market.

It's best if you can confirm with the seller in China, don't refer based on their website. It's not wrong to announce that their devices support both languages, but which language firmware are you getting?

Better be safe than sorry. 

You bought the EZVIZ C2C from China, but I am not sure if you can successfully register for account on ys7.com for remote viewing, because to create account on ys7.com, you will be required to have cellphone number from China, as far as I know of.

I am not sure if registering an account on ezvizlife.com will work or not, but you can try.

Better return the ipcam.EZVIZ China can never been used here.

My recommendation
=============

Hikvision China Set
NVR: DS-7608N-K2/8P (Supports up to 8 network cameras with PoE)
Network Camera: DS-2CD3T26WD-I3 (IP67 Protection and Minimum Illuminance of 0.002 Lux)

Hikvision English Set
NVR:  DS-7608NI-K2/8P (Supports up to 8 network cameras with PoE)
Network Camera: DS-2CD2T22WD-I3 (IP67 Protection and Minimum Illuminance of 0.01 Lux)

1TB of hard drive is enough for your need, can store up to 48 hours from six 2MP 25fps camera at 5120kbps bit rate.

Try setting up ezviz, should be straightforward after that and you'll be able to access outside home network

If not you might need to set up port forward on your asus router

Hikvision cam -> poe adapter cable -> poe ethernet switch/hikvision nvr with poe -> router

Are you using the multilanguage version or chinese firmware?
If chinese one, probably can't use ezviz here

Yeah, can still operate without monitor but you'll still need to know the ip address for nvr to configure the settings.

Try setting up with ivms 4500 mobile app and see if you can detect your device locally. Then you'll need to port forward your nvr so you can access it outside home network

For the hdd, have you tried formatting it in the hikvision setting?

I am curious how many cameras you have.

Your NVR is the one that has 8 LAN ports right?
2TB is enough for you at the moment, can even expand your cameras in the future.

Get a temporary monitor to do initial setup, such as admin password and etc.
Your NVR can live without monitor after initial setup.
But since you said you are able to view from iVMS 4500 locally in LAN, I would assumed you have done the initial setup. Because iVMS 4500 requires you to login to the NVR for viewing.
Since you can view from iVMS 4500 through LAN, next you have to setup your Asus router so that you can perform remote view from internet.
1. Port forwarding
2. Setup Asus DDNS
3. Make sure your internet IP is a public IP, request your ISP for an public IP is you found that your internet IP is a private IP.
4. Change the address in your iVMS 4500 so that it point to the DDNS address you registered in your Asus router.

If menu is in English confirmed multilanguage
2 other cameras also multilanguage? If chinese firmware you'll probably need to setup on your nvr using onvif instead of Hikvision

I think should still be possible, like i mentioned before
Try using onvif, not hikvision protocol when addding camera
Check what's the port number used for onvif on the camera settings.

Nice, so you can use hikvision protocol with different firmware language. The guys at ipcamtalk keep stressing out they're not compatible

I thought one of the camera is wired one? So you haven't install that one yet

Post the link on where you bought from or what you bought, from there fellow forumers can provide further guidance.

Last time Hikvision has their own DDNS service, they are now closed.
http://www.forum.use-ip.co.uk/threads/hikv...scontinued.988/

I am not sure if your Asus router has DDNS service offered.
My family has bought 3 different Asus router model, and they all have Asus DDNS service support.

Refer to this guide:
http://www.asus.com/us/support/FAQ/1011725/

Any dns service will do, as long as your router regularly updates ip address to the dns service. I'm using no ip since it's free

My internet speed still fine, then again I'm using wired setup and the cameras are connected a seperate poe adapter. Camera video settings at max quality, but I did reduce the bitrate to around 3000kbps for each camera for normal view.

Firstly, congrats on getting remote view of your house CCTV from your phone.
As mentioned by @alucard89, any DDNS service will do, as long as it works.

For me, wired connection is a safe bet for CCTV, because I can't afford to have lost connection or lost frames.
I will be giving my wireman to wired my house with LAN cable for CCTV, once I start my renovation.

If is just for CCTV with POE, normal Cat5 LAN able is sufficient.
No harm using Cat5e, just that the Cat5e cable might be more expensive than Cat5 cable.

Your NVR specification is here:
http://www1.hikvision.com/cn/prgs_679_i4416.html
Or international version: http://www.hikvision.com/en/Products_acces..._433_i5420.html

I don't see 3MP and I don't see H.265 in the specification, therefore not advisable to get a 3MP or H.265 camera.

Correct me if mistake found.

Well there is the waterproof connector that's included the camera for poe cables.
Using cat6 cables I got from taobao, definitely cheaper to buy longer cables there.

Better to get nvr that properly supports >4mp and above resolution like these ones

DS-7808N-K2
https://world.taobao.com/item/541903045729....6601.244.gBX9He

https://world.taobao.com/item/535606212602....6601.362.PAEIV3

I tried adding 4mp before to my ds 7108sn but it only detects sd resolution. 

DS-2CD2145F-IS
https://item.taobao.com/item.htm?spm=a312a...._u=h2avq0doc74b

From what I've read in ipcamtalk, someone suggested that i need to change the video profile, and voila nvr detects 720p/1080p.

https://ipcamtalk.com/threads/low-resolutio...cd3345-i.12291/

However, I was unable to view substream in SD, both main/substream was in full hd.
So unless you have powerful connection like time 100mbps upload speed, you won't be able to view the stream smoothly unless you set the bitrate lower.

Now there's been other feedback that said upgrading firmware fixes that, but I won't be doing since mine is multilanguage that would revert back to chinese fimrware once upgraded 

Take a read in Wiki, or any other website.
https://en.wikipedia.org/wiki/Category_5_ca...y.C2.A05_vs._5e

Me too have purchased Cat6 (Cat6a) cable from Taobao, definitely cheaper than getting it in Malaysia.
I bought from this seller:
https://world.taobao.com/item/40197923536.htm

Here are some pictures of my Cat6 cable purchase:
[attachmentid=8416112] [attachmentid=8416113] [attachmentid=8416115]
If you want higher resolution support with H.265, you can get DS-7808N-K2/8P NVR.
I purchased this DS-7808N-K2/8P NVR for my home use.
Price of DS-7808N-K2/8P will be more expensive than the one you have, but I am not sure if the NVR has English language version.

Any cat6 cable will do, as long it's connected to the poe adapter

Forgot to mention, you can still change to h264 in the settings.

Different camera model? Or the same camera model?

Double check under camera encoding and make sure that the sub stream is enabled for that particular channel.
