    Which is the better NVR?

    about that feature you mentioned, the one with two LAN port. I dont understand it, how does it improve performance? All 16 cameras are connnected to a 24 port POE gigabit switch (with nvr connected to it also), these cameras only use about 20Mbps far from the gigabit the switches can fully...

    Which is the better NVR?

    Hello i have two NVR options that i would like to compare DHI-NVR5232-4KS2 DHI-NVR5832-4KS2 I would like to know which of them is better. It will be used with 16x 8MP 4k cameras and 4x 2MP 1080P cameras. Both of them can fit to the price budget that we have, so it will come down to which...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    dahua's cameras has a max bitrate of 8000 kbps, assuming 9000kbps * 32 = 288 000 kpbs which is still lower than its maximum. So am i missing something here ? also if lets say i have only 16 4k cameras, would there be any sense to buy a 32 channel one just for the extra computing power? The...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    Well this does not really apply now since i changed my camera selection because of what you have taught me, but assuming i did get 8MP 4k cameras and lets say 32 of those, was NVR the correct choice...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    Thank you very much this thread has been very informative for me. So the one thing i learned is that sensor size is king in surveillance purposes. One last thing, does NVR matter? aside from those smart features, does it really matter? are there good or bad NVRs ?

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    ohhhhh damn, i did not notice the full color is the same one you linked a while ago ... oh definitely, this local supplier has to go. That makes a lot of sense now, their cameras cost less than 65$ which i would think is a bit cheap for a proper 8MP camera. The only thing why i did not chose...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    Okay if i throw in a full color camera 8MP 1/2.8 , its still a bad ratio. From what i read how full color works is they were designed for ultra low light, with special sensor designed to absorb more light. Here is the full color camera model that my local supplier gave me...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    oh thats so bad ! i thought the deer was on a ground with rocks, turns out to be grass. I'm curious though if you dial down the resolution of the 8MP into 4MP (2k resolution instead of 4k) would it be like a real 4MP camera?

    while we or on the topic of bad cameras. The purpose of the camera i will mention now is for surveillance. https://www.dahuasecurity.com/products/All-Products/Network-Cameras/Lite-Series/8-MP/IPC-HFW2831S-S-S2 My local supplier said it is their best camera but given what you have just said and...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    For this use case though is streaming, and do not really care about night performance for all we care it can even be pure black output on the night. The subject of the camera is typically well lit. Which would give a clearer image a 4MP 1/1.8 sensor (good ratio) or a 8MP 1/2.8 (bad ratio)

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    i notice this is for night time, how about daytime? I assume that i can get away with a higher value? Also what would really happen if i choose a ratio that is on the red side, how does that affect the image?

    Is the IPC-HFW2831S-S-S2 a good camera?

    I am going to need a camera for video streaming, wherein image quality is a higher priority than bandwith or storage consumption. My local dahua supplier said that their best camera is the IPC-HFW2831S-S-S2. It is a 8MP 4k camera, but what i have learned in this forum is that those two spec does...

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    any draw backs for choosing a high focal length camera? because why are there high optical zoom factor(such as 45x) when you can just use a higher focal length?

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    That is something i do not know, i do not have the specs of the old camera on hand, but i will keep this in mind. So to know which has better "zoom" its just focal length * optical zoom rating. The highe the numberr the bette the zoom correct?

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    Can you tell me more about this MP/sensor ratio, what do they do on image quality and what are the apropriate sensor ratio for the common Megapixels 2MP, 4MP, 8MP, and even the 12MP for that matter. The image quality looks good are those from the 1/1.8 sensor?

    Which is a better PTZ for streaming SD6CE445XA or SD5A445XA ?

    My local suppliers have 2 possible PTZ camera candidates that meet our minimum requirement and i am seeking advices on which one is better. The primary purpose of this camera is for streaming, recording and surveillance is only secondary (there are other cameras for that purpose). That means...

    what is the bandwidth consumption of a dahua IP camera

    How much bandwidth does a dahua camera specifically the DH-IPC-HFW2831T-AS-S2 (or similar 4k 8MP camera) actually use? I am planning my switch structure and this piece of info would be important so i can properly size the switches. Its a 100Mbps camera so i would assume it would not go past...

    Dome vs bullet type cameras for indoor application

    I am originally planning on using the DH-IPC HFW2831TN-AS-S2 for indoor purposes and then i happen to stumble upon an article that says dome type dont perform well in terms of image quality when used outdoor (duh its ment to be used indoor). With that i wonder if its the same situation with the...

    Its highly unlikely that we will get hit by a direct strike since there are tall buildigs with lightning rods nearby, but yes over the years there have been strike that were less than 10Km away. I would like to use dtek as they have a 8port version sadly its only for the US

    The cameras recommended are all full color though, not that full color is bad it just drives the price higher. Do you know the current crowd favorite for 8MP 4k Non full color IP camera?
