breff Posted August 27, 2004 Share Posted August 27, 2004 Back to your original question, the d4 from dedicated micros has a single audio input, the audio is only recorded while camera 1 is being recorded though. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...

It's only going to be a single channel at the moment but it might be expanded so the d4 would work for now but then I'd lose any expandability for the future.

Guest Posted August 28, 2004 Share Posted August 28, 2004 What about an AV mic. CSL & Aritech both do a good looking mic. Bearing in mind most DVRs only have a single channel audio input so if its just the one camera then its fine but no good if multiple cameras. 21806[/snapback] I looked at the CSL mic but it didn't seem to have a standard line level output on it. Single channel audio is fine but it needs to record all the time rather than just when that camera is selected. I did think about a seperate audio unit but it'll lose sync when you're playing back and becomes a PITA then. Link to comment Share on other sites More sharing options...
Guest richard pc-core Posted September 8, 2004 Share Posted September 8, 2004 I've been asked to do an installation that consists of 1 camera mounted indoors 12m away from the objects it's going to be recording. I was thinking I'll be needing a 4.3mm lens on a 1/3" CCD camera, sound about right?Next query, I'm going to be using a DVR (possibly with LAN connection, but not essential) but I can't find any with sound inputs, and if I could I've hit of a brick wall with regard to microphones. Any pointers would be greatly appreciated. 21723[/snapback] pc-core do a 4 channel safe-core lan unit with 120gb hdd and single audio input you can contact them on 01952 246688 or have a look at their web site www.safe-core.co.uk they will be more than happy to help Link to comment Share on other sites More sharing options...

Why do you ask? 21994[/snapback] just to let you know the ljd unit dose not have a good play back the pics are grainie also how oftern will your customer need to review the info as the poor compression rate uses up more hdd space ?

Guest cctvman Posted September 8, 2004 Share Posted September 8, 2004 Kev, You nicked that idea of me (& you know am right) Anyway onto the subject is this installation a covert job ??? Most pir/smoke covert cameras have a mic inside with audio amp complete with pot to adjust output If just the norm well as one post says a 3.5-8mm varifocal lens is ideal as it can be moved if customer wants more or less.... And as kev says an AV mic is the best for your job & beleve me one mic placed in a room will cover it the bonus is all AV mics have an amp circuit you can adjust what you want & dont want to hear. One thing make sure you run the mic in screened cable if a long run or near low voltage lights ects I know that the ademco range of dvr's have one audio input & most dvrs will remain @ the state of power up (if programmed).

Have you ever looked on the site? Can you spot the flaw in the plan? Did you read the spec for the DVR? Link to comment Share on other sites More sharing options...
