    Amcrest 2MP Outdoor PTZ POE+ Alarm/Audio specs?

    Right, but what voltage, impedance, etc., for the audio equipment? Im assuming mic level input, but what about the output? Would these work for the input audio? Thanks

    Amcrest 2MP Outdoor PTZ POE+ Alarm/Audio specs?

    https://www.amazon.com/dp/B095XCJWRM As usual the chinese manual that comes with this thing lists nothing about the specs of the alarm or 2 way audio. Where can I find this information? Are the alarm wires just a low voltage relay? And what is the audio impendence/level? Do the mic and...

    Multiple Amcrest cams went offline with same error at same time today?!?

    So I was able to replicate the malfunction. Seems all it takes is entering the following settings for time and waiting a couple days... And yes, the Reboot command does work! Good job Jack! The Amcrest support guy wasn't even aware of that.

    Multiple Amcrest cams went offline with same error at same time today?!?

    Excellent find. Thank you. Now I just have to replicate the malfunction again so I can test whether the API is still accessible. It was the ntp server and settings that populate the field by default. (clock.isc.org) I have tried to replicate the malfunction on my own cameras with no success...

    Multiple Amcrest cams went offline with same error at same time today?!?

    A remote reboot and a physical reset are not the same thing. Remote as in no physical access.

    Multiple Amcrest cams went offline with same error at same time today?!?

    Unfortunately I cannot revert the setting because I cannot login. Does anyone know how to remotely reboot these cameras without using the web UI? I did not detect any open telnet port but perhaps there is a way using the RTSP/ONVIF/TCP port?

    Multiple Amcrest cams went offline with same error at same time today?!?

    So now it has happened to all the cameras, at two completely different locations. The one thing I did at both locations was set all the cameras to use the default NTP time server and automatically adjust for DST. I did this two days ago.

    Multiple Amcrest cams went offline with same error at same time today?!?

    All the other cameras are running the same firmware and are all set to NTP time server.

    Multiple Amcrest cams went offline with same error at same time today?!?

    No; using an old v4 and no auto update.

    Multiple Amcrest cams went offline with same error at same time today?!?

    They are on a separate subnet with a dedicated router, the only thing that gets through that is the BI webserver port which is forwarded from the main router.

    Multiple Amcrest cams went offline with same error at same time today?!?

    Cameras in question are P5M-T1179EW-28MM. I have multiple BI systems setup using these same cameras and no problems until today. Around 16:00 three cameras go offline a few minutes apart. They give the "no signal" error in BI; won't respond to restart. Upon http access they present the...

    No app access over WAN?

    Yes they were the same. I think I figured it out. Somehow the thing got switched to https for the WAN login. I don't remember doing that. Perhaps when the app updated?

    No app access over WAN?

    Using the android app I can no longer log in over WAN. I changed nothing other than possibly windows updates. I can login with the app over LAN, as well as log in to the server via WAN or LAN from a browser with the same credentials, and on the same device the app is installed on! Furthermore...

    Can't connect to server from iPhone when using 4G

    Peerblock was running on the server. For some reason the ip range of the 4G network was on a blocklist.

    Can't connect to server from iPhone when using 4G

    Connecting from a wifi connection anywhere in the world seems to work fine (either from wan or lan), but as soon as I switch it over to 4G it fails to connect. The same issue occurs whether connecting via a mobile browser or the official app. This same phone has no problem connecting over 4G to...

    Separate alerts for each zone?

    In that case what is the best way to clone a camera? Does it actually take the feed from the camera twice, as if there were two separate clients connected to the camera, or is BI smart enough to realize what you're doing and use the same feed? Also is there any recommended settings to use on...

    Calculating bitrate of IP video

    I was hoping you would not say that lol. I will have to sit down one day and try every possible combination of resolution, quality, etc and record the incoming bitrates in BI, I suppose

    Separate alerts for each zone?

    For example I have one camera that covers both the street and the driveway/yard. The street is zone A and the rest is zone B. I want the alert clips to be stored separately so I can ascertain whether the alert from this camera is a visitor in the driveway or just a car passing by on the street...

    Calculating bitrate of IP video

    It seems that whatever I set the "max bitrate" to, the camera will use every bit of that whether I have the framerate set to 1fps or 20fps. Logic would dictate that 1/20th the framerate would use 1/20th the bitrate, but that is not the case. I realize why but the fact that they do not tell you...

    Hikvision storage managment (fw: 5.4.4)

    Can someone explain how to free up the 7 gigs of space that is for some reason being reserved for pictures after I have told it that there will be no pictures? Surely they wouldn't add two completely pointless user fields, would they?

    Setting to automatically switch profile back to default after time

    Whenever I manually change profiles it automatically switches back to default after a number of hours (8 hours maybe?). Where is this setting located? can it be set to something else? Thanks!

    Hikvision port forwarding without permission?

    While were on the subject does anyone know what these other lines are? There is no setting in the cam config page for them... App Description......Ext Port........Int Port....IP Address........Status IPC_CIVIL_CMD........9010....TCP....9010....192.168.2.64....Enabled...

    Hikvision port forwarding without permission?

    Lol. Correct! I thought I had checked that but apparently TPLink still only puts ~10 things per page, circa 1990. To view more you have to hit "next". There it was on the second page under "IPC_Control" Thank you very much gentlemen!

    Hikvision port forwarding without permission?

    I realize this is more of a networking question probably applicable to all cameras but how is it that Hikvision cameras can be accessed via the ivms4500 app without any port forwarding rules set up? The only setting that applies in the app is the "port" line which is the server port, 8000. It...

    Help identifying counterfeit hikvision...

    Ahh thanks for shedding some light on that. The seller was using the standard 2135 stock image so naturally I sent it back immediately. Don't know what else they expected to happen if they can't even be bothered to update their photo lol. After some extreme hassle I was able to translate enough...

    Help identifying counterfeit hikvision...

    Does anyone know if this is actually a hikvision? It's definitely not a 2CD2135F-IS as it shows on the label, I know that for sure; but I have no idea where they got this thing to begin with. It was missing the SD card slot (which means no F in the model number) and half the IR LEDs. If i didn't...

    BI iPhone app performance issues, alerts and alerts video playback black screen

    For some reason now whenever I pause the alerts video playback on the iphone app, the screen goes black until I press play again. Previously it would pause and actually increase image quality of the still significantly. Also clicking the alerts button from the main screen hardly ever displays...

    ARDUINO & BLUE IRIS SERIAL digital i/o DIO

    I should have used the terminal too, would have saved some time lol. Ill probly start doing that. Do you know why it seems to take 10 seconds or so to register an "end trigger" event? Does that happen to you too?
