Thanks again, and I like your answer lol The only thing I don't understand is, if it is rated 24W, how it can power 50 or 60W in appliances? By the way, this is the version I have in mind, which is more powerful, but isn't so well documented as the lighter version...

That was also the understanding I have, but why they show this picture and these spec? 1 CCTV camera + router + DVR, can backup power for 12 hours 2 CCTV cameras + routers + DVR. Backup power for 6 - 8 hours. 4 CCTV cameras + routers + DVR, backup power for 3-4 hours

My cameras are analog. DH-HAC-HFW2221R-Z-IRE6 - Dahua My main concern is if I can hook up multiple cameras.

I would appreciate if someone could have a look at the below link, and explain to me. https://zircon.co.th/en/product/dcupszmn45 They have a slightly more powerful version as well, which you will see at the bottom of the page. DC UPS ZMN616 It concerns a DC UPS rated at 24W. Yet they connect...

I have plenty of those, as I sell devices that use them, and they work fine, but I liked the power supply I have because of the UPS function. When using it on battery, the picture is perfect

POE is not an option with my cameras, so can you suggest something reliable?

It seems the major problem is my power supply. I measure 11.83V at the camera while operational, but I get slightly distorted picture. When I unplug the mains from the power supply, so UPS function kicks in, the picture is perfect. I also can replace the power supply with a 12v 2A power...

This is my current setup, and I hope someone can help, because I'm losing it. I have currently 7 cameras installed. It are HDCVI cameras dh-hac-hfw2221rp-z-ire6, and get the signal over high quality Cat5e with passive baluns. My XVR is XVR5108HS-I3, and I set up with monitor connected to the...

Also this, how do I confirm? I can move the arrow between confirm and cancel, but don't know where to press confirm and make disappear.

This is the recorder. https://www.dahuasecurity.com/products/productDetail/60397?from=rss Supports 1080p up to 8mp

Still struggling to set up my cameras. These are the settings I applied for 1 camera. My cameras are dh-hac-hfw2221rp-z-ire6 So it is set to 1080p 15Fps, but when I go to the PTZ of that camera, it shows it is 1080p 25Fps, and I have no option to change to 15Fps, only 720p 25 or 50Fps. What I...

You mean your 30 meter lengths are powered over LAN? It was the main reason why I started this thread, and I was advised against. Had I known your real life experience, it would have saved me quite some hassle.

This is mine, with built in UPS, which switches without any interruption.

Thanks for the suggestions, but I explained already that I can't get my head around those formula calculations. So I rely on the online calculators. I only wanted to know if the manual calculation gives a different result from the online calculator.

I do not have POE, and it isn't an option either

I don't have POE, but a 12V power supply I'm using below calculator, which states single length has to be used. https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html I now also notice my mistake, by measuring the voltage with no load at the end, which obviously will have no loss...

I just figured that all those online voltage drop calculators aren't worth their money, even when they are free. My installation is now completed. In 2 locations I used 2 core 1.5 sq mm copper multi strand VCT power cable, over a length of 25 - 30 meter. 1.5 sq mm is between 15 and 16 AWG...

In my camera settings I have choice between H264 - H264B - H264H and H265. Bitrate CBR or VBR. Which are the recommended setting? I notice that I can only select up to 15fps, while the cameras support 30Fps. All the above is using the app and remote configuration

Ok found the digital zoom, they really could have made those tabs in the top left corner a little bigger lol

My cameras are all varifocal 2.7 > 12mm hac-hfw2221rp-z-ire6. When I connected the XVR by hdmi to the monitor, I could zoom in and out using the scroll wheel

And looks like I'm still missing a lot. Also still no settings to zoom or whatever.

Thanks, I normally use Firefox, I tried now with IE, and yes those settings are there now, but I guess I have to use binoculars. Any suggestion how to get rid of the >confirm cancel?

Looks like you need a Phd in something to use Dahua cameras lol. I have discovered how to get rid of the download certificate by watching a youtube. Now one of my cameras shows > confirm cancel in the middle of the screen. Any idea how to get rid of that? Also my cameras are varifocal, and...

I have a Dahua XVR5108HS-i3, and 8 cameras. Before I installed I tested the web interface, and got screen with 8 cameras when I clicked on Live. Now I have the whole thing installed, open the web interface, and see a screen with 4 cameras, which all 4 show a black screen with the text download...

It's about $30 a month, but for other reasons, like IP's that get blacklisted, I prefer not to have a static IP. They gave me one for free a few years ago, and I asked them to switch it off. P2P method works fine, only wanted to know if there are security issues

I only see 1 fan in my XVR, so don't know which function it has, but it keeps running. I have external power supply In the online manual I notice that previous models of the XVR had a power switch .

Not only that,but I guess if using that method have to sign up with a DDNS service as well, because I have dynamic IP which changes every 24 hours

I'm aware of that, but I actually want the fan stop running without the need to unplug the power

I have the DH-XVR5108HS-I3, which has no physical power button. When I select shutdown from the menu, the device shuts down, but the fan keeps running. Any way to sort that? Another question I have is, can I prevent from automatic logout, so that whenever I connect over the web interface...

I have my Dahua DMSS app linked to my XVR using the P2P method, as I'm too dumb to setup a reliable free DDNS. Is using the P2P method safe, or should I really opt for the DDNS method, and if so, which service do you suggest? Cheers
