You VGA cable sucks. If the VGA monitor supports 1920x1080, bring it near the DVR, and try with a short VGA cable.

Only 16ch.

No.

You need 12VDC, no clue where you got it can work with 24VDC.

*ONLY* Internet Explorer, not Edge. Just connect to any Hikvision DVR, and it will download the needed IE plugin.

On Windows you can only use Internet Explorer.

And your DVR is exactly which one...?

Make sure you are using Internet Explorer, and NOT Edge. Look for IE icon, right click, run as administrator. Choose folder where you want the recording downloaded.

Look again, your DVR has RJ45, not RJ11.

Your cameras are being detected as PAL (CVBS) by the DVR. Since they are 4in1 cameras, you have to change them to TVI.

Yes they are, since you said "It seems that the LEds in these cameras do not last very long". They are crap like the IR boards you buy. If you want them to last longer, do not buy crap.

DS-7208HQHI-F1 and DS-7208HQHI-K1 support 8 BNC channels, plus 2 IP cameras. It surely sounds that for whatever reason like it is trying to go to/show channels 9-10, which they do not have any IP camera configured. But that should NOT be happening by default. Is the end user using the mouse wheel to scroll through channels? Or is the unit showing that error without anyone touching the unit?

What you are looking for is WDR. All current Hikvision models will have BLC. I would say that all will also have DWDR (digital WDR), but you are interested on true WDR.

If you want it well done and clean: Cat6, video+power baluns If you are cheap: Cat5, video only baluns, and power connectors. If you are even cheaper: Cat5, video only baluns, and power connectors, and you might even want to try using a single Cat5 for 2 or even 3 cameras.

Connect your mobile to your 2.4G wifi, since your mobile will configure the camera with the wifi it is currently connected to.

Your DVR restarts, so it obviously does so.

Gmail and Yahoo are the issue. If you want to send emails with a free provider, you will have to keep trying/looking around, they won't make it easy for you, since they do not care about those who want to send emails using SMTP. Port forwarding has nothing to do with it.

The guy that works here has your answer, you want his address?

3G/4G router and use Hikvision's P2P service (Hik-connect)

You need to contact whoever sold it to you. Only the original seller should reset it/delete it from someone else's P2P account. (like, we only reset devices with serial numbers that have been sold by us)

Smart PSS works with Dahua units. MJK CMS software works with MJK units.

What CMS platform?

SmartPSS is only for Dahua devices. You will not be able to add a MJK unit, no matter how hard you try.

Probably a customized firmware from the reseller. Ask them what app you have to use. Some resellers use different P2P servers, so their devices will not work with DMSS/SmartPSS which both use Dahua's P2P servers. When that is the case, it does work from inside the wifi/LAN, but not when you are outside ther network. You need to use their own app, or just flash Dahua's firmware so it will use Dahua's P2P servers. You can usually find out if it is a personalized firmware by checking the firmware version. Instead of being something like: 2.420.0000 It will be like: 2.420.XX00 (where XX are two letters instead of numbers, since the dealer name is DiyaKala it might be 2.420.DK00)

http://IP:port (using Internet Explorer) If you do not know the camera IP, you can use Config Tool from Dahua (download as standalone, or as part of Dahua Toolbox) to see your Dahua devices on the LAN.
