Re: Security cameras, networking, DVRs

Night vision is good to about 45 feet with the internal IR LEDS, but that can be supplemented with outboard IR illuminators if necessary.

I will look in the manual on Sat and see what it says to answer your question.

Look Outside
How do you power it if it's outside? I think I might buy that.

Will the IR/any other fancy feature still work behind a window? I can always put it on my enclosed porch which has an outlet.

I know my motion detector lights don't work behind a window.

12 volts. You could use a POE splitter rather than 2 cables.

If it is behind a window, then have aux IR illuminators outside rather than the internal ones.

I'll turn on the IR now for the overnight...

Not really sure what that is. Also, with the IR, does it turn on automatically or is it something I have to manually do?

I'm more concerned with night time activities.

POE splitter...

The internal IR can be on, off or automatic.

What else is needed? Wouldn't I have to move to a POE setup?

I noticed that someone posted that the POE source has to be within 25 feet of the camera. Is that true? I'm thinking of a more remote operation, where the camera would be a couple of hundred feet from the house and I'd want to send it power across that distance. Is that possible?

The cable I made was 25 feet...it can be longer if necessary. The problem is not insoluble.

If it's 12 volts, I could use a storage battery on a trickle charger to power it. That way, it the power goes off, it could still send images to my system and modem which is on a UPS. The time would be limited by Battery/UPS capacity, but could still function long enough to capture some images.

We got a Lorex setup last week, and the DVR died on Thursday (clicking, blinking red light inside). I'm sure we can get a replacement, but how do I trust the security to a new DVR when the previous one lasted 4 days?

DVR's use hard drives. Its totally within the realm of possibilities for a new drive to go AWOL. Cooling issues, surges, brownouts, manufacturing defect, or a stray cosmic ray, can all contribute to drive failure. Probably wouldn't happen twice, but YMMV.

you do it by switching to a modern system where the cameras all record to SD card (which is solid state) and then upload to a remote DVR after they finish writing to the SD card.
most modern cameras e.g. axis, trendnet etc all have this capability as standard.
look for : PoE capability, variable shutter (night mode), SD card support. The good ones will not have IR LEDs (which are useless anyway). instead you put a IR light (or any light with an off the shelf IR filter set (blue/red) you buy from any art store) which is bright enough to illuminate the area properly and put it on a motion sensor.
thats the right way to do it. the old model of one easily broken DVR per location is silly.

Actually my Trendnet with built in IR LEDs work pretty awesome in no light.
