    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...

    Record to network share

    Well said dogbert... also for newbs, #3) Changing the blue iris service to log in with the blueiris account is done under Windows, computer management, services. There should be a BlueIris entry running in the list if you're running it as a service. Right click it, \properties\login then edit in...

    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...

    turning off desktop pc

    A vpn would also work and is recommended, but I agree with fenderman. I'm curious your reasoning for not wanting to leave it on 24/7?

    Ip Cam and Network help needed

    If "-Able to record and save 24/7 on the office server" is a literal requirement, then the NVR wouldn't be an option. If the server is offsite (remote access), then you will need to setup a vpn between the 2 lans. Once you have that site to site vpn rolling, all you need is a camera that can...

    Rainbow Corruption

    beepsilver, thanks for the feedback. Ironically my starlight variofocal turret is my only camera that has not actually done it (yet). I think that may just be a coincidence, however I have also observed that the webui on the turret is much faster responding than the other 2 starlights (a mini ir...

    Rainbow Corruption

    I sometimes find it too hard to give up... New mobo bios went in, along with slightly older drivers from the hp website. I had the latest drivers direct from intel, and an ancient bios. Maybe the older hp ones will work on my hp rig together with the bios? If not, I'll try again with the new...

    Rainbow Corruption

    True, I didn't think about the fact that the recordings will be ok. It was all the false triggers that were annoying. I hope it never fails again for that reason alone. Kev [Update: yeah... frigging rainbows, again. I'm about done with ha lol.]

    Rainbow Corruption

    Say it ain't so! I have to temper my excitement. If it happens once more I'm switching back to h265... and crossing my fingers that the darn pc will have the balls to handle more cams as I add them. Last thing I need is to see rainbows after I find my truck was broken in to! Kev

    POE cam with 2-way audio - BI

    From my understanding, there are 2 types of horses available now. 1) proprietary cams that work well but being proprietary require a separate app to use, and 2) onvif compatible cams with audio out that sucks. Seems most if not all cam manufacturers are struggling with delivering onvif 'talk...

    LAN Setup preventing IP Cam traffic??

    Well you gotta do what you gotta do. If you don't mind me asking, what bitrates were involved before (at 4k I'm guessing?), and now at 1080p? If it's handling an 8kbit h264 stream, there are plenty of good cams available... even 4kbit would be ok for h265. How about WiFi signal (g/n, XXdb)...

    Rainbow Corruption

    Update: I wiped/reinstalled everything fresh on my bi machine after I swapped in a new 3tb purple drive. Then I decided to give ha another shot... now it has set a record of 24hrs without a hiccup. Looks promising compared to the previous 10hr record between corruption incidents... will report...

    Dahua Camera Audio Noise

    Today I fixed the intolerably crackly gargling audio on my newer mic'd Dahua cams! The secret was disabling noise reduction in the cam's webui. Try it; the difference in sound clarity is night/day. Fwiw, this is with my cams' default 64k-711a encoding. Kev

    Looking for input before final mounting

    I have only been working with the well known cams in these forums. It doesn't surprise me that manufacturers tend to obfuscate that critical bit of info. I haven't dug into it yet, but I figure there may be a way to calc H fov based on focal length (known for almost all cams) and sensor (ie 2mp...

    Looking for input before final mounting

    If you're like me, and you prefer viewing a situation through the lens of mathematics, make note of these basic equations: D = Distance from lens to object Theta = FOV of lens (angle) O = Half horizontal FOV (object plane) R = Horizontal Pixels A = Area Resolution (PPF) V = vertical pixels...

    LAN Setup preventing IP Cam traffic??

    Did you verify if the netgear device was hardwired or wifi to the dlink device? If it is WiFi, going hardwired there may improve bamdwidth.
