    Is this correct?

    Hmm, I should have done more research before I opened this thread. I just notice that I can purchase RG6 coaxial cable with power cable attached, at about a third of the price of Cat5e cable. No Baluns or whatever needed, and since I already have network cable installed, I can easily attach...

    Is this correct?

    Thanks I was just looking at the voltage drop over 30 meters on a 24AWG wire, and it quotes 2.5V drop over that length. I presume 9.5V will not be sufficient to operate the camera, so would it be safe to use a 15V power supply, or do you have another suggestion, because of course not all...

    Is this correct?

    I have 6 piece of these HCDVI cameras HAC-HFW2221R-Z-IRE6 Cat5e cable is installed already. I have these baluns Video Balun Now I plan to buy this 8 port POE switch POE Switch So since I already have the Ethernet cable in place, can I use just 1 Balun at camera side, then transfer power...

    Which Balun do I need

    Thanks again for your kind reply. I have 6 identical 1080p cameras HAC-HFW2221R-Z-IRE6 Before I saw the PoE NVR, which is obviously of no use for me, I considered either the XVR5108HS-S2 or the XVR7108H-4K-I2 , where the latter one is about double the price of the former. As I'm a noob in...

    Which Balun do I need

    Thank you for your detailed answer. I searched for Hybrid NVR, but couldn't find one that is PoE enabled, can you maybe point me to an 8 channel one? My cameras are HDCVI, but I have the network cables already in place, so I want to avoid replacing them with coaxial.

    Which Balun do I need

    I have these Dahua cameras HAC-HFW2221R-Z-IRE6 And intend to purchase this NVR, which has PoE built-in, so to my understanding should be able to power the cameras over network cable, without the need of any other power source. Is that correct? NVR4108HS-8P-4KS2/L Previously, I purchased...

    Making my own PoE switch

    Not so sure about that, going by the comments of bigredfish, who owns this camera and IP cameras as well. HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    Making my own PoE switch

    I did find this, as I posted in my previous message, but in my book 12V 8.6 W means 0.71A and not 1.4A. 8.6W / 12VDC = 0.71A Why do sellers recommend 2.5A if 0.71Ais what it really needs?

    Making my own PoE switch

    Because it was much cheaper than the same spec ( motorized varifocal) in IP camera, and they are 2MP, which means better picture at night

    Making my own PoE switch

    I understand the camera will use only the amps it need, but I think a Cat5 wire is limited to something like 1.5amp, and I also don't know how much the camera actually need. In the spec it says maximum 8.6Watt power consumption, which is 0.71Amp, but on Ebay listings I read recommendations for...

    Making my own PoE switch

    I have purchased 6 piece HAC-HFW2221R-Z-IRE6, and will use Cat5 wire to connect. Therefore I have purchased the following video balun. Cameras came without power supply, which I think is standard. I know they are are 12v but I can't find anywhere how many Amp the power supply should be...

    Dahua HCVR or XVR

    I took it to the extreme with my 3fps > 30fps comparison, but with 15fps the chance is of course only 2 times. I'll look into it again if i can find a 7108 at a reasonable price, but so far it is about a 80% premium over the 5108, and in my opinion it isn't worth that. Thanks for your...

    Dahua HCVR or XVR

    Ok, in both videos I clearly notice a difference in smoothness between 15fps and 30fps, but the clarity of the video is actually the same with a 3fps as it is with a 30fps, and I think that is the important factor in security surveillance. So even a 3fps recording would show me the face of the...

    Dahua HCVR or XVR

    Thanks again for the explanation. A final question. Taken into account that my cameras will only record footage inside my perimeter, so only slow moving objects, is there any advantage to get the 7108 over the 5108?

    Dahua HCVR or XVR

    In my neck of woods we have smart phones already :lol: So varifocal is same as zoom. What is digital zoom? Does that mean I can zoom in on recorded material? Or is this possible with the 5108hs?

    Dahua HCVR or XVR

    Thanks for the detailed response. I think you're right about the HCVR5108HS-S3, however in Vietnam they call it XVR, and that may be the reason that I also found it as XVR here in Thailand. But can I assume that for my purpose the HCVR will be fine, since I only use the Dahua cameras I quoted...

    Dahua HCVR or XVR

    Hi, I purchased Dahua HAC-HFW2221R-Z-IRE6 cameras I'm looking at the XVR-5108HS, but I'm getting confused by all those specs. To be clear, the camera will not target any fast moving objects, so I guess I'll be fine with a 15fps frame rate. Is this recorder capable of recording in 1080p at...

    I finally got the HAC-HFW2221RP-Z-IRE6 for 65 Euro (~72USD ) include shipping from a European Ebay seller with a close to 99.5% positive feedback score. Ordered 6 pieces to get that price

    Offer of $80 include shipping for the HAC-HFW2221R-Z-IRE6 was accepted, damn should have offered 75 :) Now I see there is also a HAC-HFW2221R-Z-IRE6-DP. Any idea what the difference is or what the DP stand for, as I can't figure it out from the Dahua website. HAC-HFW2221R-Z-IRE6-DP | Dahua...

    You never sleep or what? You were online before I went to bed, and now you still are lol. In the camera looking over the dock, the vegetation in the bottom left corner, how far in front of the camera that would be? Looks like a nice area where you live

    Thanks mate great videos, I think the gator had his reflectors on lol. In the last video at what is the height and focal length of the camera, and what is the closest point the camera sees?

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    I saw your pictures from the 2221R-Z, so guess I'm gonna send the 2221R-Z seller an offer, at least he listed he was open to offers. You have video of that camera posted somewhere?

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    Where did you see that the Chinese 4MP has true WDR? In the spec from the seller it says DWDR and the same is listed for the 1200R, only the 2221R-Z seems to have true DWR

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    The more I read and watch youtubes with an agenda, the more difficult it gets for me to make the right decision, so maybe I should stop reading and just place an order. lol I will not order the Starlight cameras, since that is over my budget, so it is either HAC-HFW1200R-VF-IRE6 or...

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    Thanks, I'm well aware that the starlight versions will be superior, but it would double the cost of my installation compared to the 4MP version and that isn't worth for me. Now regarding that 4MP camera, I did a search on this forum and there are several threads all from the end of last year...

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    Thanks, one last question. I notice in the spec that this is a varifocal lens, but there is no mention about motorized, so I guess I will have to disassemble the camera to set the right size and there will also no zoom available. So may be better go with the IPC-HFW4431R-Z at 15 Euro/piece...

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    The camera I have in mind is the HAC-HFW1200R-VF-IRE6, which I can find on several official Dahua sites, including Thailand, Middle East and Russia. I have a feeling that the camera is discontinued, but I get it for 53 Euro include shipping from Aliexpress, so I consider this a good deal. I'm...

    HAC-HFW1200R-VF-IRE6 vs IPC-HFW4431R-Z

    I just watched some youtubes showing a comparison in frame rate and as far as I could figure, but my eyes and brain are old already :-) , the higher frame rate seems to be more important for fast moving objects. Since my cameras are only viewing inside my closed perimeter, I don't expect many...
