Run base station on 12v

[suraeight]

I want to run the base station on 12v. It seems that this is possible.

What adapter do I need or do Netgear has any accessories for this?

You don't need any adapter as the wall transformer supplies 12dc@1.5a.   What you would need is a big battery/ 12 power supply and a fused, center positive 5.5mm coaxial plug.

Word to wise tho, if your running on a battery, the base prob draws less than the rated output of the transformer, So I would say 1 amp would be safe estimate.

A typical car battery is aprox 80-100 ahr .  So your run time is aprox 80-100 hours .  ( yes, i used quick math, it's an esitmate )

Not knowing why, but it would be a cheap way to run at a remote location without a UPS. Just run from battery with an automatic charger on, when power goes out , you got 80+hrs before it dies. Power comes back and recharges the battery. ( variable rate charger of course )

Hi TomMac and thanks for answer.

I would run the station (and camera) in our caravan where I have pretty big battery connected to a charger which I can run when we are in the caravan and run on 220v.

Regarding the cable, do tou mean something like this?:

Or do you have someone to recommend?

Yes, that's a coaxial cable.

But I wouldn't recommond using the comman cigar type plug.   It's to easy to come out.

BEST; I would either hard wire into your fuse box ( always fuse as close to the battery feed as possible ) 2nd Best use a locking type plug from like Marineco

( the male half goes in and does a 1/4 turn to lock in tight ) OR BMW type cigar socket

BMW/DIN type ; http://www.ebay.com/itm/Continental-DIN-12-V-Accessory-Panel-Power-Socket-Outlet-Fits-BMW-Hella-Plug...

Coaxial plug is I believe 5.5mm ( had asked once before but not 100% ) so verify size with netgear) CENTER positive

Question tho... how are you running the eithernet connection ?

Something to ponder is that a straight battery connection will give you a bit more than 12VDC - probably not an issue.  However, when charging the voltage will be higher, as high as 15 or so VDC, which could cause an issue. Some sort of voltage stabilizer could be useful.

[TomMac]

I would guess that since he's running it in a caravan/camper voltage regulation is already taken care of since most use 12v lighting, etc.

Chargers and regulators on cars, shouldn't be over 14.5v - 14.6   But good thought just in case.

Anything with a built-in regulator would be fine - we just don't know if that's true for Arlo or what the input voltage range specs are. As for car regulation is concerned, we have a GM car (Cadillac ATS) with a battery display that shows over 15v on occasion (the system is set up to minimize alternator drag for gas mileage purposes).

[TomMac]

Yes, we don't know yet , but maybe soon.  !  🙂

Actually a simple ( cheat ) method is to insert a couple of diodes in line on the +.  Normal diode has voltage drop of .6v , so he'd have a 1.2v drop before the unit.

But a better way if not sure would be a LM7812 regulator chip ( cost about $1.50 ) for 12v out , very simple curcuit. ( good for 1 amp but not much heat as V in will be close to output )

[jguerdat]

I pondered a voltage regulator but there needs to be sufficient input voltage to be regulated down to 12v. I'm sure an electrical engineer would easiybe able to figure this out - my old electronics technician skills are pretty rusty...
