    The thread does also seem useful to me.

     

    If somene would decide to do this using the admin account, well, no comments... I guess that anyone who is able to embed an image on a web page should know better than that.

     

    Not doubting usefulness, just the presentation that certain terrible security practices can be okay. There's no way anyone was suggesting using admin...

    And with that, I'm logging out and leaving this site, not because of this thread but how this site is run. It just wears you down over time as this is less a forum and more of just a sales platform for installers/integrators.

    I did comprehend it. When is putting the user/pass in an public facing HTML file good? You are aware idiots/morons won't heed your tiny warning at the bottom. They will put this right on the internet. Yes, it's just an example of how to do it with no security but its absolutely irresponsible to even show that at all IMHO. IP cameras are borderline linux boxes and should be treated as such at all times. The only problem is these linux boxes have security exploits waiting to be found and you're telling people how broadcast ROOT to the world.

    Here's how to embedded an image from a protected storage. Oh btw, that's not secure.

    It's impossible to know what you consider "unacceptable" without a baseline. What FPS is not acceptable? What cameras were you using? Distance the IR had to go? External IR used also? You could have 640x480 crap at your work or 20MP Axis cameras.

     

    You can get 2.1MP/3MP IP cameras that can do 30/15fps respectively. As long as it isn't pitch black you can get 30M IR distance. Bullets, domes, and turrets for ~$120-$200.

    It's best not to mix brands.

     

    It will pull the video as you set it. Nothing should change. That is for video setting changes e.g. white balance, exposure, contrast, etc.

     

    More advanced features like motion recording, alarms, triggers, storage, recording schedules, etc may not work though even if you set it correcting. Of course it could work too. Won't know unless you try it.

    100% yes. I see a street light there too.

     

    20M IR

    1.3MP bullet 720p Dahua IPC-HFW2100 $89

     

    30M IR

    2.1/3MP bullet 1080p Dahua IPC-HFW4300S $125 shipped from CCTV CAMERA CHINA @ aliexpress

     

    With that street light, you will be able to get very close to the reported distance. Personal testing I can see 20M in pitch black with a 30M rated IP camera. Neither of those cameras are expensive. Sounds like that person only sells analog.

    Software is free with Dahua (PSS) or Hikvision (ivms-4200); prefer the latter, this will run on server.

    HP ProLiant G7 N54L MicroServer Server System AMD Turion II Model Neo?? You don't need much but if you are doing other things on this like you want, it may be too much. Recent Celeron/Pentium is fine; an Intel i3 is the max I would use for your situation.

     

    Cat6 is a waste. IMHO, I would opt for cheaper Cat5e. Does gigabit and will carry power over ethernet the same.

    Sounds like you recommend the HIK over the dahua? So if I bought either a HIK or Dahua on say Amazon, would I get a warranty or any kind of phone support should I need it?

     

    Ive never heard of aliexress before but I will check them out. Myabe I missed one but when I was looking at the NVR I dont remember seeing one that was HIK with the same features as the Dahua 5208. Some of the HIKs either had no drives or only half the ports were POE or for both it was more than the 5208.

     

    There's no warranty with the amazon sold units. You have to go through authorized dealers for a warranty. Amazon and all the security sites spammed here aren't authorized. No warranty. No support. Most are just the same chinese imports you could order yourself form aliexpress.

     

    I like hikvision cameras better. I like dahua's NVR/PC software UI better. I didn't bother mixing them because I wanted to avoid all problems.

    There are two feeds coming for each camera. The full resolution main-stream and the lower CIF/MJPEG lower resolution sub-stream.

     

    You are likely trying to view 16 main streams on the live view. That isn't happening and even the best CPU will choke on that. You have to either switch to the sub-stream or find the setting to "auto-switch" between them on the live view (double click to enlarge--switches to main stream; the reverse shrinks back to 4x4).

     

    You should have no problem viewing 16 substreams with your setup. It will still record at full resolution. The only taxing thing is viewing the full main stream. Force highest resolution sub-stream (near D1 quality) or change to "auto-switch."

     

    The same exact thing applies when viewing playback video.

    Thanks for the help. Seems a little hard to find actual dahua cameras from somewhere I normally buy. For instance Amazon caries the nvr but only I think three cameras. Are the cameras rebranded to a different name like q-see???

     

    You can buy Q-see which are rebadges or buy from aliexpress (Ebay for china).

     

    Hikvision are much easier to find and what most people buy (including myself). Costco carries Swann which are hikvision rebadges.

     

    You're going to get tons of posts/PM's about where to buy cameras. Most of those will be gray-market and have no USA warranty. IMHO, just cut out the middle man and buy where they buy from--aliexpress.

    Hello. Totally new to this and have been reading through some of the posts. I'm looking at setting up my 1st home system. Probably somewhere between 4 and 6 cameras. 2 indoor the rest outdoor. As of now looks like I'm liking the Dahua 5208 they have on Amazon. I think I can decide on that. I really need some help on cameras if someone can help me with my questions....

     

    Do I have to try and use dahua cameras with that nvr? I read over the Ultimate IP Camera guide. Could I pretty much use any of those name brands like ACTi with the 5208 or only specific cameras from each?

     

    # of MPs. Do I choose a camera based on the distance? So I put a camera about 15 feet up under roof eve facing street which is about 60 feet away. Would 2mp camera be fine or less? Not sure how I choose how many mp's to get.

     

    I see some cameras support mxpeg which I guess is new and better than H264? Is that a camera specific thing or does the NVR also have to support that?

     

    Another thing. Suppose I get IP cameras that support SD cards. Should I assume that I can write to the SD card AND the nvr or is that a specific thing to look for per camera? Not sure I want to but curious.

     

    My last question might be more for the nvr, but when I see like on the 5208 that is supports FTP, does that mean I have the ability to offload, backup ,replicate- whatever you want to call it- video etc to ftp cloud storage OR to a small several TB NAS located somewhere on my network?

     

    Thanks! I hope someone can give me some additional guidance.

     

    No, but not all features may work be compatible if you don't match brands. There is a chance it could work 100%. IMHO, I would stick with the same brand if using a dedicated NVR.

     

    FOV, megapixel, and IR/night vision reach. Do you want a tight shot 60ft away or a wider overview? That is FOV. You can pay more for varia-focal (adjustable zoom) vs fixed focus. Megapixel is up to you. The higher the number, the better detail and ability to zoom in. 2.1MP = 1080p and should be fine for most people today.

     

    SD card would be an advanced feature where brand matching can decide whether it works or not. Most camera's allow you to log-in to the camera directly, but sounds like you want it to work with the NVR.

     

    FTP means FTP. Can be for video, stills, or both. Depends on model. Off-site cloud backup of video is going to be a lot of data/bandwidth!

    ___________

     

    You can also skip the dedicated NVR device and use an i3/i5 Windows PC.

     

    Dauhua and Hikvision both offer great free software (only that respective brand works). There's other software but it's $200-$600 for it as their "Free" versions will likely be restrictive to your backup needs. Axxon Next, Xprotect Go

    What is bitrate and why is more better?

     

    You know how when you watch streaming video it starts kind of "blocky" and then gets clear after a bit? That is the bitrate changing. Higher the number (to a point) the better the video will look.

     

    The absolute highest bitrate my 3MP hikvision bullet can send, at least according to specs, is 16Mbps. That's one camera. I don't run them that high because higher bitrates eat storage like crazy so I keep it lower (4-8Mpbs). If you used the same bitrate as I do for your 3 cameras that's 12Mbps-24Mbps; that's over what you're NVR can do.

    Is it possible to get 8 lower end IP camera (dahua?) ,NVR, switch, for under $5k? Do I need an NVR or can I get software that records?

    Thanks.

     

    You can do that easily under $3K USD. 3MP cameras too.

     

    Costco NVR package

    or

    i3/i5 PC + costco hikvision/swann cameras + switch/cable + free Hikvision iVMS-4200 software.

     

    For $5K you could get all that installed, buy larger hard drives, have a battery backup, and have a few dollars left over.

    Ignore the extra monitors. You can get an i7 and one consumer nvidia card to playback 64 1080p completely untouched, original streams? You have to be using something to dump extra information to display that amount of megapixels during that scale down. That's four 8K video streams of information being played back! Now with professional cards or SLI/dual SLI you can push things but not consumer cards.

     

    Yes, we do and can, I am repeating.

    but no idea of the differences what's consumer or professional cards. We use G series from nVidia. Nothing else. With 64 Channels of 1080P bit stream , No problem. Around 100 Channels of 1080P compressed stream could be the bottleneck when reading out from a HDD. But it is not really because there could be multiples of HDDs or Multiples of Gigabit Internet ports or SSDs(solid state device-new & faster hard disc). Currently, we are looking at a graphic card of U$80. With that we do decode almost 32 Ch 1080P, each 30 FPS. What I mean "almost" is that we are now trying to reduce the CPU load to less than 35 %. The reason is that we have to allow system makers or developers to put on their own value added/enhanced GUIs or applications, say object tracking, face recognition,etc. I will let you know when it is on the market. I left a PM, last night, arriving to you, soon.

     

    "We are only of 6 engineers who design the chip as well."

     

    What chip is that? $80 USD is a consumer level graphics card. I want to believe you, but red flags keep showing up. I wish you the best of luck if true.

     

    Cheers.

    Wow this situation is exactly what our NVR is designed to solve... our NVR with Smart Search.

     

    Here is how it works:

     

    http://www.youtube.com/watch?v=o0Zgq73LEiE&list=PLavMykS0nm2_sb61rLnO4Hk-M4kHwnvVM

     

    The smart search results is like the flags you are talking about.

     

    too bad its only at the machine side that this can be done :/

     

    I don't think people are understanding the OP correctly (or maybe I'm not).

     

    1. Predefine on-camera motion zones.
    2. Record 24/7.
    3. Timeline is marked when camera sends that the motion zone has been triggered.
    4. Timeline shows recorded footage in one color; different color when motion trigger channel goes off. Once motion ends, goes back to regular color.

     

    Doesn't have to be colored, just flagged for quck and easly viewing later. Doesn't have to do a smart search of find anything. No flags when off, no point in reviewing it. In that video, he would have to do a "smart search" every single day on the same exact door.

  23. Posted

    You could probably trigger jpg capture for motion while recording video continously. At least that would flag when motion was happening.
    Good suggestion for compromise; i will play around with that.

     

    Or you might be able to script a solution... It's maybe more hassle than you are prepared for though.
    Yes!

     

     

    Guess it's hard to believe that without advanced pixel search, nothing can be flagged during continuous recording. Maybe I'm thinking about this wrong lol

     

    Check out the Axxon Next VMS. Generous 16 cam free license. See the youtube video I posted.

  24. Posted

    That's too bad. I guess I'll report back if I find anything.

     

    In my mind the camera is always identifying motion, so I don't see why marking that on the timeline would be different if record was always on. (I'm not a programmer)

     

    As you can see the dealers pushing avilgion even have gaps in the recording. That's not what you want and I don't know why they posted that other than to push sales.

     

     

     

    Axxon Next does what you want:

     

    As you can see, it's made for an operator but you can adjust it. It should tag it with an alarm (red indicator on timeline). Free version is 16 cameras, 1TB storage, 1 server.

    This limitation is due to power drop along the cable.

     

    With a short cable or a larger gauge wire, you'll get more power at the device for a given current. This is a good reason to use cat6, even though few cams run over 100Mbps, since the wire gauge is slightly larger.

     

    Presumably, this minimum power delivery rating is based on maximum spec cable length and minimum spec wire gauge.

     

    Or take 10 seconds to learn about PoE and don't waste money on cat6. You can't power a class 4 device with a class 3 PSE.

     

    This is basic engineering, not POE. The 12.95W spec is worst-case, and is due to wire resistance at max power load. The extra power is dissipated along the cable due to current and cable resistance.

     

    Lower resistance wire and shorter runs will decrease the total cable resistance and increase the power available at the end of the cable.

     

    Worst case is the best case with the classes. Class 3 max is 12.95W. If the PD requires 15W, it's a class 4.

     

    Axis labels their cameras correctly for the max power available:

    http://www.axis.com/files/datasheet/ds_p13_p13e_47290_en_1204_lo.pdf

     

    I agree and understand what you're saying perfectly, but it doesn't really help the OP and his problem. e.g. say 15.4W over Cat6 ends up 14.95 at the PD; what is he to do then? Buying the correct switch or using a high powered injector is a better solution. People need to follow the PoE classes and drop the obsession with "full 15.4W" that seems to permeate this board.
