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. |

1 edit | 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... |

Look Outside | 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. |

The internal IR can be on, off or automatic. |

Look Outside | 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. |
