    Yes that's our initial thought. But once again, since we want to keep the data usage down + reduce the amount of work of the server, we are wondering wether or not some IP camera models allow us to do that?

     

    Also if not:

     

    - Is it possible to change or make changes to the embedded system of a camera?

     

    - Can we buy a camera without embedded system, and develop our own one?

     

    Thanks

     

    Automatic x seconds of video every x minutes doesn't sound a feature I've seen in any of the IP cameras I've fiddled with.

     

    Your best bet might be to put a cheap rasperrypi and a camera module and then develop a program on the raspi to capture and send the video. Google search for rasperry pi, camera module and programming should get you started.

     

    For example https://www.raspberrypi.org/documentation/usage/camera/raspicam/ and more specifically the raspivid section there for the recording, then some way to send it to your centralized server (ftp, or such?)

    Hey,

     

    We have had problems with their video servers/encoder in the past. Older models are still required to be on automatic reboot, or they get stuck after a while (could take days or weeks). Newer models do not seem to have this problem anymore, but i believe you just have to wait and see.

     

    I suggest you leave it off (no auto reboots) and if you have any problems with it, enable it. If you have to enable it, make sure you schedule it to reboot at night time so it will not do it during busy hours.

    Hello,

    I have problem to capture snapshot.

     

    I am using the following model:

    Device TypeIPC-HFW1120RM

    Software Version2.420.0000.4.R, build : 2015-04-17

    WEB Version3.2.1.262736

    ONVIF Version2.4.1

     

    I am using the following command to capture a image:

    http://192.168.1.108/cgi-bin/snapshot.cgi?chn=1&u=admin&p=[mypassword]

     

    Problem:

    1.It still asks for username password pop-up even though i am supplying the credentials. (check screenshot)

    2. After manual authentication, snapshot works sometimes, but refreshing the page or using the same URL repeatedly stops giving out fresh snapshot.

     

    Please help.

     

    You need to add the credentials to the url the way browser understands them:

    http://admin:password@192.168.1.108/cgi-bin/snapshot.cgi

    Usually, if both devices are Profile S conformant and listed on the official ONVIF site, at least basic streaming and configuration will work. However, it is not guaranteed. There are still some instances of combinations not working.

     

    Good correction. However some of these non-working instances can be solved with a firmware update, as the firmware conformant is listed on the DoC.

     

    ONVIF actually updated their policies (I believe it was Sept 2014) and made their conformance process a bit better. Now the cameras actually must be tested on several devices and devices on several cameras, so cameras and devices tested after Sept 2014 will probably work together with higher possibility.

     

    The features are also a big questionmark on most cases, as most of the features are optional, and mostly only mandatory features are supported.

    ONVIF (Profile S) is a standard protocol used on mainly on IP cameras and recorders. If a camera supports ONVIF Profile S and recorder supports ONVIF Profile S, they work together.

     

    Now when a product claims it supports ONVIF, make sure it really does from

    http://www.onvif.org/FindaProduct/ProfileProducts.aspx

     

    This official search will tell you if the camera actually supports ONVIF. There are many cameras on the market that give you a big shiny ONVIF logo and claim they support ONVIF, when in reality they don't.

    If you can use a custom RTSP path on ISpy:

     

    2x 180 degrees panorama: onvif-media/media.amp?profile=profile_2_h264&sessiontimeout=60&streamtype=unicast

    4x dewarped image: onvif-media/media.amp?profile=profile_3_h264&sessiontimeout=60&streamtype=unicast

     

    So the full address would be rtsp://ipaddr:port/onvif-media/media.amp?profile=profile_2_h264&sessiontimeout=60&streamtype=unicast

    Axis M3007 (http://www.axis.com/products/cam_m3007pv/index.htm) does have better image quality compared to cheaper 360 camera (DynaColor W-8 Fisheye, http://www.dynacolor.com.tw/prodDetail.asp?id=25). I have not tested Hikvision cameras, so I can't comment on that one.

     

    Axis M3007 does not have IR, and it's low light properties are not too good. DynaColor W-8 has IR but it seems to reflect from the dome so much that it makes the image un-usable (not properly tested, just something i noticed from overnight footage at our office).

     

    Here is a image comparison, zoomed dewarped image showing a picture at the wall, about 3 meters away from the cameras. Both streams are 5MP@8Mbps (H.264) and no compression/high profile/max quality. Images are not from identical angle because cameras are mounted side to side.

    DynaColor W-8 Fisheye

    And image comparison of fully zoomed out images, DynaColor has a bit wider FOV, but that's because the lens is physically mounted closer to camera bottom. Because of this, the edges of the image on DynaColor are sharper, as not as much dewarping is required.

    I'm not completely sure about the prices for these cameras, so i wont even try to guess anything.

    Our installers are now using/testing Metricu M-IPC-700A ( http://www.metricu.com/Products.php?cid=11&id=89 ). Supports most of the IP cameras we've tested, including Axis, Sony, Dahua, Hikvision and many others.

     

    More detailed specs can be read from the link, price is around $600 (google told me, from a romanian webstore).

     

    It's very handy when all you need up at the ladders is this one 7" monitor that weights 2650g.

    Just get NVR software to do that.

     

    Thanks. I'm not clear on what an NVR does though?

    All I need is for the camera to write its files to a network share.

    Do IP cameras do that?

    Once the files are on the computer, I can view them with the web server.

     

    NVR (Network video recorder) usually means a dedicated hardware with some basic functions.

    In buellwinkles case "NVR software" means a software that can handle these basic functions and probably a bit more, since it runs on an actual PC with operating system.

     

    The last option would be whats usually called VMS (Video management system/Video monitoring system), which usually gives a lot of features to handle the recording from hundreds of cameras, digital I/O, license plate recognition, analytics, video walls etcetc.

     

    So in your case, NVR software (viewtopic.php?f=19&t=35868 Scroll to Video recording software) would be the best option. These software actually record the camera streams to a non-video format, which you can then playback within the software, and only export important parts as a videoclip. Most software also has web-server and mobile client support aswell.

     

    Since you only want to record single images now and then to a ftp server, you can probably do that without any software at all since most of the cameras have "Screenshot to ftp" functions.

    You can use 2 different programs/computers to view/control/record this camera, atleast it does support 2 streams, and probably more than 2 connections at once. Just make sure you get programs compatible with the camera or with a generic ONVIF support.

     

    If you only need to control the camera rarely, you could try ONVIF Device Manager (http://sourceforge.net/projects/onvifdm/), free opensource program that allows you to connect to and ptz control your ONVIF cameras.

    The backblaze articles are actually a bit invalid for this forum, as it is a backup service, the usage is not anything like in recorders. They do give a nice overall picture of which manufacturer might be the "best", but there are no HDD's that are meant for recorder usage on their 2013 or 2014 setups.

     

    We have used Seagate Barracuda in the past (failure rate VERY high) and SV35 (recommended for surveillance video recorders) series recently (past 2-3 years) with very low failure rate. So my experience kinda fights against the backblaze statistics, but as i said, they've not used any HDDs meant for recorders, as their usage is completely different.

     

    No experience on any other manufacturer.

    It was the radio link (Ubiquiti Nanostation Loco M5's).

     

    Fooled around changing bandwidth from 30 back to 40, raised/lowered the signal strengths... managed to lose the connection totally a couple of times...

     

    Finally came back to original settings and re-booted the AP radio.

     

    All cams now online.

     

    Lessons Learned:

     

    • Radio link problems *can* be camera-specific. I have no clue why, but that seems to be the case.
      .
    • One of the first things to do in a case like this is to re-boot the radio links. Kind of like troubleshooting a Windows PC issue: when in doubt, re-boot.

     

    Thanks for posting your results and how you fixed it. I've always thought all sorts of wireless stuff (except phones i guess) are way too unreliable to be used when something actually needs to work (security for example), sadly it's not always possible to go wired...
