    Power consumption (supply current) depends on the device model. Check the technical data for every camera and DVR/NVR and don't forget to add HDD consumption. Consumption is practically constant and not dependent on the states you've mentioned, only cameras with IR illumination have lower consumption in day mode. For example, small Hikvision's day/night camera consumes maximum 4 W , and 4 channel DVR 10 W.

    There is no difference in power consumption between analog and HD or IP cameras, because the analog cameras are also "computerized" using DSP.

    Starting (power up) time is different for each DVR/NVR. For analog and HD cameras it's almost instant but IP cameras need some time to boot up.

    Event trigger is instant, motion trigger starts recording even some time ( 5s typ.) before the motion event.

    Check your router's WAN IP address (somewhere on Status page) and real one (whatsmyip.com or canyouseeme.org) . If they are not the same, thids is the problem:

    Mobile internet ISPs often do not enable port forwarding. If they use "WAN IP sharing", then you have another router(s) (which you cannot setup) between your point of connection and internet. In this case only solution is P"P (cloud) connection.

    I'm not familiar with SRD-443 but it sounds like an old DVR and probably don't support cloud connection.

    I suggest testing iSpy . It's free, open source and has a large list of compatible devices, both DVRs and IP cameras. I tested it briefly, it worked OK, but haven't checked all the features.

    Other solution is Milestone. Very powerful, full of features, but also very, very expensive.

    Lack of static IPs is no problem, use some commercial DDNS service for all sites. Dyn.com is the most popular, $40/yr for 30 sites and available on practically any device on Earth.

    Good luck

    I have problem with latest version of iVMS-4500 for iOS on iPhone 6. I add new device (DVR) normally, and get all available cameras' pictures. Some time later I can see only Camera 1 . If I try to reconnect to the device (Devices-Edit-Save) I get also only one camera.

    I tried reinstalling iVMS-4500, got all cameras for some time, maybe an hour or so, but later I get only one camera again. This happens on iVMS-4500 installed during last 10 days on iPhone 6. On Androids everything works fine. Also, it happens both with old 7208 HVI/ST DVR and and new Turbo HD DVR, so it surely has nothing to do with the device.

    Try disconnecting both devices and scan IP addresses on the network (I suggest Advanced IP Scanner) to check if there is any IP address conflict, ie. is there any other device with ...1.80 or ...1.82 address.

    Next, try using different IP addresses (192.168.1.180 , 192.168.1.182)

    And finally, one question: what kind of network equipment you use, is there any smart LAN switch or something like that?

    Since you have a NoName DVR , it's impossible to identify it.

    There are two things to do:

     

    1. try to connect via web browser (usually Internet Explorer). In LAN connection url should be something like this

    http://192.168.x.yyy(:ww) without brackets

    where x.yyy are two last numbers of DVR's IP address and ww is DVR's HTTP port if different from 80 otherwise can be ommited.

     

    2. make a snapshot of the application window and send. Someone could recognize it.

    Last week I installed two Hikvision's DS-7104HGHI-SH Turbo HD DVRs with V3.3.2 firmware. Both times I noticed strange behaviour:

    After full setup (network, time, camera resolution, recording schedule, DDNS etc.) everything had worked fine, but later , upon power restart, all settings were reset to factory default except network and user settings, same as Restore function in Maintenance menu. Of course, I didn't open Maintenance menu. I work a lot with Hik's DVRs and this never happened to me before.

    Any ideas ?

    Very probably not !

    Most commercial RF modulators are made for composite video (PAL/NTSC) input and give analog TV VHF/UHF output. AHD is HD technology developed specially for video surveillance systems. But, if you have an AHD camera with double BNC output (both AHD and composite video) or AHD DVR with BNC composite output then you can use these signals to connect to RF modulator. Or you can use VGA to video converter and convert DVR's VGA output to composite video. All these solutions give worse picture than the original, D1 in best case.
