... or "tvtime", which I use to watch analog input TV on a BT848 based card. You could also try supplying a known-good analogue signal (from a composite output on a DVR/camera/anything else) to the card's inputs. If the signal from your camera is not a properly compliant PAL/NTSC signal, you may wel...

Somewhat brutal -- some day that joke will backfire when someone tries it ...

I'm assuming your original problem is when the camera is in "auto" mode, and it decides whether to IR-cut based on illumination level. Of course, if it is switching on an IR source, this will increase illumination which will cause it to think it's daytime again. It may just be with the IR cut filter...

Is this practice wide spread? As a lot of these backdoors aren't documented (security through obscurity) it's hard to know until they get exploited, or unless you worked at the company making them ;) For one camera, there was an unpublished URL (e.g. http://camera/video.cgi , http://camera/admin.cg...

Splicing CAT5/6 cable together with twist+electrical tape is not exactly within specifications. It may well work, it may introduced noise/emissions or a rather nasty reflection in the cable that stops it working. Alternative idea: An external grade small weatherproof junction box. Drill small hole i...

Is ‘GOP’ a technical term here? Do they buffer up to a certain point then batch send? Would then the image corruption be related to packet loss in all likelihood? If so, that’s a lot (?) of loss for a hardwired link.. (I terminated the cable myself but fluke said it was good..) Is tcp support typic...

Well I found my error - I had the monitors set to UDP, needed to be TCP. UDP is not a reliable transmission method, in that a packet can turn up none, one, or more times. In no particular order related to other packets. If you accept that behaviour as part of your system design, then it's fine. But...

I got three dirt cheap cameras off AliExpress. Two 1080p indoor cameras that cost me €20 each (including shipping) and a third 1080p outdoor camera for €30 (including shipping) All three are setup on zm on a raspberry pi 4 4gb and now running fine (I had an issue getting all to work simultaneously ...

You have the right word for it! Try searching the forum with the phrases "FFMPEG tearing" "FFMPEG smearing" -- this does come up from time to time, and should be fixable.

... BNC cameras? Is there a good balun gizmo? You may need more than a balun to get you out of that one. Don't be fooled by seeing cheap balun devices that can adapt a BNC (coax) to twisted pair (cat-5) that have no real electronics in them. They are JUST cable adapters ... all they do is correctly...

It was a delay by viewing it directly through it's web GUI. If the camera is suffering from its own incompetence, then I'm not sure ZM would improve that :) I was hoping you'd say the lag was not there when viewing directly, but laggy in Zoneminder. Glad you got it sorted by downgrading the firmwar...

Is the 30-45 second lag there if you watch it "independently of Zoneminder" (i.e. its own app, its own web-page, through VLC ...) ? Or is the lag being caused by Zoneminder settings, e.g. having accidentally set a frame rate in Zoneminder (should be blank!) which is not the same as the camera's fram...

My recommendation is to look in places other than Which? for reviews and ratings, especially on technical matters. Find a computing mag, and try again! :) You want to know about ease of use and consumer friendly? Then sure, some widely-supported, current fashionable-trend security-gizmo like Nest/Ri...

So often that it would corrupt the LAN routing tables making hosts on the LAN slow or unreachable. Camera being flaky aside, there is something else wrong with your network/router. Does this camera have a fixed IP address? (If not, give it one!) -- as it could be the constant requests for an IP add...

Yeah so many cheap UPS's will not turn on unless there is enough juice in the battery. So when power comes back... your machines don't. Not useful. It depends what you want to happen (and the consequences of that desire!) "Not turning on because: Battery dead" is a good feature IMO. A lot of APC on...
