    Firmware for newer dahua cams as well as detailed specs available here

    The dahua api does have a manual focus and zoom function. I had issues with autofocus when switching between day/night modes; autofocus gives up (times out) before the exposure settles in after switching modes. This left my cameras out of focus. To fix it I programmed my vms system to send the...

    Switch Dahua Day/Night Profile via IPC HTTP API

    LOL Darkflame, I like your avatar! You could try something like this. Dahua API v1.56, page 52: SetAlarmOutConfig http://<ip>/cgi-bin/configManager.cgi?action=setConfig&AlarmOut[port].Mode=<paramValue> -port = Alarm out port index starts at 0 -paramValue: 0=auto, 1=force on, 2=close alarm Kevin

    Trigger blue iris with IVS?

    I did spend some time using highlighted motion in BI to tweak object size and sensitivity. I stopped playing with them after I got 'em down to an extra trigger or 2 only on very windy days. A guy could spend the rest of his life working toward zero false positives; for some situations that's...

    Trigger blue iris with IVS?

    I tried playing with this using ODM with my 5231r-z (July firmware ...14...). I turned off motion so the cam is only using IVS. Under ODM 'metadata' it shows some info regarding the IVS messages, but they do not appear in "Events". Seems wierd ODM seems to find the IVS rules but fails to get the...

    Multiple html commands in sequence

    Thanks Darkflame! It's time I refresh my linux scripting skills and that sounds like a good way to do that. I will also look into autoit and _iecreate. The curl method might also be a good fit with a dedicated linux lpr box. Kev

    Polarized lenses

    I was aware of polarization angles and planned for testing whatever methods I try. In my case though, the putting a box out there would have too negative an impact on curb appeal. It is tucked in a small roof return on my single story home.

    Switch Dahua Day/Night Profile via IPC HTTP API

    It depends on the cameras involved. Like the OP of this thread, I've got a bunch of Dahua starlight cams. They all have similar html get commands based on the generic Dahua HTML API. First I had to go in to each cam and setup both day and night modes according to my previous post, and set them...

    Switch Dahua Day/Night Profile via IPC HTTP API

    It really depends on what you're doing with it. I'm no photography expert by any means, but I have found with security cams you have to keep a tight leash on shutter speed and noise reduction to stop motion blur. Here is an example of what seems to work well for me at the moment. My Z5 is used...

    BI build question re: low end CPU

    Win10pro I bet you'll be happy as a clam with the i5 6k. Intel HD+BI is like a match made in heaven.

    Multiple html commands in sequence

    I have been using BI event schedule and custom ptz commands to switch my dahua starlight cams between day/night mode, as well as refocus a few of them. On a normal day it's a great setup; just after civil sunrise day mode goes on, a few seconds later focus is done on the motorized lens cams...

    Rainbow Corruption

    A quick note on #2 from my previous post: "ONVIF login/logout" lines do normally appear on my camera logs when BI sends html get commands from an event schedule (ie, morning time BI sends a command to switch to day mode then refocus). However when the log is due to a get command, there is...

    BI build question re: low end CPU

    Mr.N00bLaR, I was born a diehard tinkerer. So I truly do appreciate the enjoyment that can be had by tweaking with voltages and clocks, but honestly from my limited experience with IP security cams I have to agree with what fenderman's suggestions. A proper and efficient hardware accelerated...

    Rainbow Corruption

    1) Happened on lan as well (100mbps on an way underutilized enterprise switch... 3 cams 8k a pop... plenty of overhead). My vpn, which I use for remote, gets a minimum of 18mbps upload throughout the day. 2) I had the same thought that it could be just a dropped packet... but further inspection...

    Rainbow Corruption

    Update... from rainbows, to gaps in continuous footage. My system has been up and running since my previous post without the type of rainbows we've discussed so far. However now I have noticed 3 other problems which are just as vaporous to troubleshoot. The first one is more of an annoyance...

    How to handle DST changes on multiple cameras?

    For those who have asus routers, Merlin firmware includes ntpd. That's what I use, together with some routing table entries that isolate my cameras from the internet. My router would be bored and underutilized otherwise. :)

    How to handle DST changes on multiple cameras?

    That appears to be just another ntp daemon (utc). Having to do dst on the camera is I think the central issue here. So no 'pure ntp server' stuff will help. Whatever it is has to do post processing after ntp sync, before time is sent to a requesting camera. I agree syncing more often is ok...

    Polarized lenses

    ...wonder if Andy could talk to his manufacturers and see if they could make a z12 with filtered glass. That would be perfect for the job!

    How to handle DST changes on multiple cameras?

    Hmm... per that apps page: "NetTime works internally with UTC (Universal Time) and doesn't have any code for handling daylight savings or time zones. As long as Windows is configured correctly, it should automatically handle daylight savings changes for you." Most connected gizmos these days...

    Polarized lenses

    Thanks John! My original idea was to get a small sheet of polarized glass and either glue it to the front of the cam, or maybe 3d print a mount that slips over the front. However both methods would make it hard not to also block the ir leds, which I want to avoid. Anyone taken apart their a...

    Polarized lenses

    I have a Dahua starlight bullet (z5) lpr cam setup that does the job well, and it is also in a good position to ID driver/passenger faces during the daytime. Although sometimes glare gets in the way, especially when their windows are all rolled up. Has anyone here tried messing with polarized...

    Can't access BI via Mobil App on work wifi

    This old post is probably already sorted, but for future readers I wanted to add to looney2ns good post: Use TCP port 443 anytime you are at a place that is likely to block certain types of connections. Work, schools, etc... usually block a bunch of stuff to prevent unsanctioned use of their...

    VPN app for Android

    I recommend using the open source "openvpn for android" instead. First because it works with the newer GCM ciphers (aka 'tls-crypt', it is way faster and more secure). The official openvpn connect app has been lagging on support for tls-crypt. Openvpn for android also has a lot more settings...

    Major problems connecting to server from outside home network

    Cor, it doesn't have to be complicated. Your router may have openvpn built in; those are imho simple to setup. Back OT regarding login issues, I have been experiencing intermittent hang ups when I login to my server from the android app. It is not a complete fail, but if the app is set to show...

    Change Brightness via Http post command

    I use the method bp2008 mentioned; it's fairly newb friendly, but has it's downsides too. I have no use for 'pure IR on/off'. So I setup Custom HTTP to use "IR on/off" to switch my cameras between day/night mode. I also customized the 'focus far' BI command to refocus my cameras after switching...

    Port forwarding stops

    Thanks looney2ns, this thread has a lot of support for upnp and port forwarding, which are both red carpets to a hacker. These days with OpenVPN, there's really no excuse to not use a VPN server at home to secure all remote access to your LAN. Doesn't have to be some gnarly server, just an Asus...
