    How do I check to see if a Dahua NVR5216-16P is the early model or the later version? (Version1 or Version2)

    Hi, I have just seen an NVR5216-16P-4KS2E (note the “E”)for sale on Facebook market place, second hand and never used due to failed project.. (Coincidentally my new one from Andy@empire is in transit and arriving via FedEx on Monday) Anyway, I read the huge thread on these and know there is a...

    How much bandwidth does a particular camera use - How do I calculate it?

    Hi Thanks for this, Would you add a WD Purple or Seagate Skyhawk to this old PC or just go with any drive? There are claims out there that you really should use a dedicated surveillance drive.

    How much bandwidth does a particular camera use - How do I calculate it?

    Thanks Can you refer me to a link that explains this? I would like to read up on it and study it. It sounds like it might be the next stage after I complete my current learners steps, nothing wrong with learning one and then stepping up.

    How much bandwidth does a particular camera use - How do I calculate it?

    Great point! So I would need to update my router to 1GB? What about the Poe switch? Should I get one with a 1GB uplink?

    How much bandwidth does a particular camera use - How do I calculate it?

    And your comment is precisely the rabbit hole I am exploring. I want a great resolution and am aware that FPS and bit rate limit even great cameras. I would rather spend $1000 (our dollar buys 60 cents US) on a capable NVR that will kill it versus $400 and feel limited. Hey, I am going to...

    How much bandwidth does a particular camera use - How do I calculate it?

    Thanks This is exactly what I was thinking but as I have a very technical mind I like to understand “why” and how to calculate it……. Its strange but I like to understand the workings and then i feel comfortable versus just fit a box. Its like I need to know “why” otherwise I feel...

    How much bandwidth does a particular camera use - How do I calculate it?

    Thanks What I found was that the 4108-4KS2 was limited to one or two High res (4K or better) cameras due to bandwidth of only 80mb/s (unless you use 8 low res cameras). This means that the NVR 4208 -4KS2 with 200MB/s incoming bandwidth was still a bit limited if I added better cameras. This...

    How much bandwidth does a particular camera use - How do I calculate it?

    Hi, I see that as the cameras increase in MP you need to have an NVR capable of receiving all this increased volume of information/bandwidth. The NVR4108 series has 80MBS incoming bandwidth, the 4208 series has 160 MBS incoming bandwidth and the NVR5216 has 300 mbs incoming bandwidth. Yes I...

    Build & design advice please - for joint neighbourhood Licence Plate camera installation

    Hi all, some help would be appreciated for a neighbourhood meeting next week. Background I live in a semi rural area on a 3.5km long loop road so there is only one point of entry and exit. Across the road from the entry is a small private trotting club and we can potentially instal a tower or...

    What do you know about Dongjia Cameras?

    Old brand Closed down and few records on internet Any known issues with this camera? I have a new one here that someone never used (about 5 years old) Apparently fell appart in the post, heat sink fell off and some screws fell out so he just binned it rather than put in a clients house. It is...

    Can you explain CMOS chip measurements?

    Hello, Why is a 1/1.8 in the T5442T camera bigger than 1/3 and 1/2.8 on other cameras? Can you explain how this measurement works and how to use it to calculate the actual area of a sensor? I like to understand the specs I am reading

    Thanks - yes I did consider this, the threads on changing fans are interesting and I am still reading them. However quiet is a big deal for me.
