Dc Splitter Advice

[kuchars22]

Hi,

I'm planning on adding a microphone to the front door cam. The cam is already connected using an audio/video/power extension cable, so I would like to plug the mic into the audio socket of the cable, but I also need power, which the DC socket is already occupied by supplying the camera.

My questions are: FIrstly, is there such a splitter that will plug into the DC power connector and split into two, so it can feed into two devices (mic and camera in my case)?

Secondly, the mic only requires about 20mA, whereas the camera would be less than 1000mA (exact requirements not specified by the manufacture). Would a 1000mA DC adapter power both without problems?

THanks

What type of camera are you using that requires almost an Amp of current? Do you have a make / model number?

If you are in any doubt as to whether the PSU is adequate for your needs, why not just step up to a 2 or 3 amp supply? Also make sure that both the mic. and the camera work on the same voltage (12v DC?), and double check the polarity for both.

very good advice,

with out the spec of the camera its very hard to judge, the only type of camera that i can think of that takes 1 amp (1000ma) is a large LED IR Day/Night but like you said

Doktor Jon, 2 to 3 amp sorts that problem.

Camera is Sanyo VDC-DP7585P. The manual only says it can work on 12V, I think I'm using a 1A regulated PSU for the cam. The centre pin is positive on this.

Thanks

ive just had a look at that camera and its nice thing, why not get a good regulated 3 amp psu (over engineered i know) but then use your 1000ma (1 amp) psu for your mic, if your mic is only taking 20ma at 12v then the psu wont even get warm, well maybe slightly.

dont penny pinch, put some LOVE into it

The cabling negotiates quite a few tight corners and holes, and I wanted to reduce the number of cables from 3 (DC for cam and mic and coax video) to 1 (DC, mic and video), then split the DC by the dome.

you can get some mulit core cable with screened coax in, so you will be able to do that with one cable, you'll just have to find it.

here is an idear !

whicks and B & Q sell those budget cctv kits (not for use, I know) BUT the extention cables for those kit have multi cores and (screened) cheep tho, but will work.

special cctv cable mmmmmmmmmmm

Looks all complicated to me. Besides, the cable is already in so I'd like to stick to that. Screwfix do a 4-way splitter so I may just get one of those, and try it out on a 1A PSU.
