    you could try some commercial level nvr like onssi, milestone, etc. you really have to research this one deep though depending on how many different manufacturers you are using, which models, etc.

     

    Well we are looking for something that also has bells and whistles like remote config, 3g mobile phone viewing, point of sale alarm capabilities. Upgrading 20 stores to one platform would be expensive. Honestly I want to find the best way to do this that will work effectively and (somewhat of a joke in technology) last us for a while without becoming outdated. We can go with IC Realtime and get a decent deal on something that looks to be good for us but I am concerned because they dont seem to be an industry standard from what I've found (mind you Im somewhat new to this)

    another small thing to note is that 2way audio is not necessarly the same as voip or a traditional sip client. 2way can function more like a walkie talkie with half duplex conversation whereas a full sip client can have live full duplex conversations like for video conferencing for instance. also there are many more control options on a sip client than just 2way audio.

     

    finally the codecs being used as well as the settings on those codecs (nevermind the hardware side) can really play into whether the audio is worth it on a unit or just marketing bs. for instance many dvr 2way codecs are simply .wav audio and they don't implement time stamps properly for conversations so the actual audio is out of whack, skips a lot, etc.

     

    this is an interesting topic and i would love to hear actual experiences on it with specific hardware setups if anyone has direct experience. i know it is against the law in many states at least in the US but i am interested discussing this topic as i believe it should be fully supported (IMO as a sip client not just 2way audio).

    you can improve it by telling avermedia to increase the size of the images using the mobile viewer which just uses the /mobile images. the size of these are 170x instead of 320x which is what it should be for an iphone. most companies allow you choose different picture sizes but this is not the case with them; and so when you stretch the picture you will lose detail. especially if you are not trying to clean up the artifacts after stretching.

    different companies implement ddns differently. some are proprietary solutions since they make the hardware already. in these cases they usually are not the typical ddns. something more like a combination of uPnP, Zero Config, etc. which are typically mapping mac addresses with ip. hopefully they support some kind of heartbeat or auto update ip address procedure but who knows how often it updates.

     

    dyndns is usually a good way to go though.

    many years ago i did the ccna, ccda, ccnp, ccdp in 3 months. i bought a couple of 2501, 4000 series switch, and a 2509 for remote terminal access. at the time BnN still had a 30 day return policy on books so i used them like a library. between those and a routersim it was pretty easy. of course things have changed. the newer tests require much more in-depth knowledge. in fact the routersims today are much more complicated than when i was doing it (just used for basic commands back in the day not full interoperable networks like now).

     

    in the end the ccna is the way to go.

     

    i still have the equipment i believe if you want some cheap ones. i am sure the o/s would need some serious updates though.

     

    routersims are a good start though without having to get the hardware. eventually though you will want some real world experience with real routers/switches.

     

    also i don't know if this applies to low end cisco products but most enterprise stuff is done via ciscoworks these days which is all GUI based anyways.

    we did a video demo of foscam here:

    just be careful what you are getting because this line is a series of clones and they all have different firmware. i have seen plenty of people brick their cams doing a firmware update only to find that the cam is really a clone and not the one they thought it was. for instance foscam and goscam are the same with different firmware on some models.

     

    they tend to lock up a lot from people who come to me with them.

    we did a couple video reviews of them here:

    i have seen them lock up at times remotely and i can't get into them for a day. usually when i pull the mpg4 stream if it happens. other than that the picture quality is very good and they are a good bang for the buck IMO.

     

    IMO stay away from linksys and dlink

     

    other ip cams in this range might be

    axis m series 1011, 1031, etc.

    axis 207

    panasonic bl series

    lorex

    trendnet

    airlink skyipcam

    aviosys 9070
