Hi, I am looking to purchase a camera/NVR setup for my home, with 1080p minimum resolution. I have done quite a bit of research, and narrowed it down so far to: Hikvision and Dahua cameras and NVR, possibly using BlueIris. My favorite NVR so far is the Dahua NVR4208-8P or possibly the NVR4216-8P, both include 8 PoE ports, although there is another version of these without PoE. I have read that these HD NVRs, as well as the Hikvision, are very NOISY, which is a concern for me considering the future location of the unit. I would prefer to have a PoE-enabled NVR, but if the non-PoE version is quieter because the power supply only needs to output ~20W vs. 140W+, I would go with the quieter non-PoE version and get a fan-less switch with 8 PoE ports. More precisely at this point (still open to other suggestions), I am trying to decide between: - Dahua NVR-4208-8P (PoE) with 2 or 3 Dahua HFW4300 cameras - Dahua NVR-4208 (no PoE) with a Zyxel 8 ports PoE switch and 2 or 3 Dahua HFW4300 cameras Also, I would like to buy them from a US seller in case there is a problem/return needed, and it seems that both companies do not support equipment purchased online, even from US companies, and lots of sellers offer an unbranded version with firmware/language issues and slight differences in specs/packaging. QUESTIONS: 1) Is anybody familiar with the Dahua or Hikvision NVRs in PoE and non-PoE versions, and could tell me about their overall experience, and how loud they compare? 2) Can anybody share their experience and suggestions getting supported/warrantied Dahua or Hikvision equipment from US sellers? 3) I have seen some new Dahua systems with IP over coax offerings, HDCVI. This seems to offer wiring compatibility with existing setups and less risks of interference than a cat5e/6 wiring. Has anybody tried these and can comment ? 4) Also, I have read somewhere that Lorex NVR might be a rebranded Hikvision NVR. I had looked at both Lorex and Q-See 1080p offers since I am a Costco member, but the real reviews are quite bad in general for both. At one point, I was close to go with a QT-7xxx series (the more recent QC series software seems too unreliable), for overall performance and easy setup and remote access, but Dahua and Hikvision seem better quality, except that their remote web access seems very limited, no Chrome and older Java6 required, whereas I have seen rave reviews about the QT remote access (my Comcast installer even gave me a free demo of his home setup access). I think I am probably going to stick to Dahua or Hikvision, but I'd like to hear from people about the remote access experience to these NVRs (and cameras) from a PC browser or an Android phone, since I want to be able to access these from work and also from Europe where I occasionally travel. I am planning to make a final decision this week since I have an upcoming trip early November. Thank you, Rob

Thanks for the info. I hadn't researched the HDCVI actually, but noticed new offerings while shopping online and thought the I might stand for IP. Now that I know, ll won't even bother looking into them. Regarding the NVR noise, I understand that it's model specific, and I was actually hoping for feedback/experience regarding specific models from Dahua and Hikvision, especially those with PoE vs. those without. For instance, I am trying to decide between Dahua's NVR4208 (non-PoE) and NVR4208-8P (PoE), and I wanted to know if the PoE model is louder or the same as the non-PoE version. I have gotten confirmation that the other model NVR4216-8P has a very loud Delta fan, not sure if it would be the same in the NVR4216 and in the two NVR4208 models. I am not concerned with the noise of the hard drives I am going to put in, just the fans which generate most of the noise. Since the power supply of a PoE model would need to have higher wattage to power up all PoE cameras, the manufacturer might have put one or more bigger/louder fan(s) to keep it from overheating, whereas the non-PoE model just needs to power up the internal boards and hard drives, and could go with a smaller less noisy fan or less of them. I am actually looking more at the non-PoE models, because I just found out that I should get a separate PoE switch if I want direct access to the cameras. I still want to know if there are any non-PoE models that are quiet, especially if the Dahua NVR-4208 or NVR-4216 fall into that quiet category or not.

@camtastic: I am pretty much at the same (un)decision point now as you were back in February, except maybe for slightly more recent Dahua NVRs 42xx available now with and without PoE, and the fact I would rather get Q-See QT series instead of QC due to poor software ratings. Could you share with us what you ended up buying, and what your experience has been so far? Thank you!
