How can I record multiple audio on a CCTV DVR with one audio input. I have four cameras with audio and only? one audio input line on my DVR system. I need to record audio from all four cameras. Is that possible? What can I do?

You need a mixer - google "4-Channel Passive Mini Stereo Mixer".

I know his Fryness likes gadgets, but since when is this a technical board?

Just solder the four cables together - there is a chance this might work...

But then there's also a slim chance you might blow everything up if anything was badly designed...

Your choice.

PS: 25 at Maplins for a 4-channel mini-mixer...

I find myself hovering and waiting for a commercially-linked solution to this problem to be magically revealed by the OP, but perhaps I'm just cynical.

Chaps - wherever possible, please refrain from commercial linkage - it makes this moderation lark a tad awkward. A suggestion for what to google is better unless unavoidable.

hahaha, was that irony? Oh.

Sorry, Jenny. My bad.

(other search engines are available - and all are commercial concerns - search for one you like using... errrrmmm... cuil?)

Dammit - tripped up again! Google is rapidly becoming a generic term for search engines, and of course any search engine of your choice would do.

What is the name for that? Synechdoche? We need suze to tell us!

Cool word... at least three double bonus QI points for that... and spot on the money to my reckoning...

Synecdoche is certainly a rather wonderful word! Metonymy is another, and could also be used to describe this genericization of a commercial name. (Opinions differ as to whether all synecdoche is also metonymy, but it really doesn't matter.)

Google Inc really doesn't like people using its name generically, and occasionally instructs its lawyers to send out (rather futile) "cease and desist" letters. The OED appears not to have had such a letter - and probably wouldn't take any notice in any case - but it reckons that a lower case <g> should be used when one is being generic.

Which is exactly what Jenny did in post 728049, so even more points!

And don't even think of using Portacabin as a generic term unless you want a stiff letter from some lawyers (or you want to make sure some lawyers keep themselves out of trouble, don't mug old ladies &c, by writing pathetic and meaningless letters)

Perhaps it's a marketing ploy attempting to overemphasise how pervasive the google brand is.

You don't send out "cease and desist" letters if you're not going to follow them up - unless it's a marketing ploy...

I'm going to bing/cuil/hotbot/yahoo/dogpile/ask/baido it, and see if I can back that up...

In either case, it's still advertising a commercial brand... no matter how insidious. Can we put those extra points in escrow?

Hormel tried to discourage the use of their trademark to describe unsolicited email, again a possibility of free exposure.

I just wrote myself a note in biro, while I walked along a travelator in nylons, to remind myself to hoover the lino in the portacabin next to the tarmac road. Dynamite!

Lucky we developed the majority of language before copyright/trademarks... otherwise every word would be a legal battle...
