    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

    I think of POE as managing the voltage drop this way. The camera actually does run on 12v through POE, but converts whatever arrives of the 48v through the long run down to 12v. Short run? 47 to 12v. Long run? Convert the 18v (or whatever) that arrives to 12v. As long as it doesn't drop below...

    Because POE is 48v. Some cams capable of POE will also have a secondary power dongle which is usually 12v. Higher voltage carries current much better over a distance on small copper wires. If they used 12v over 100m on hair-thin wires it wouldn't run a thing by the time it got to the far end.

    External IR for Foscam FI9900P - Spider Issue

    Turn that Foscam into a puppy cam or something and replace it with a modern Dahua or Hikvision. Just about everything supports turning off the IR for the best usage of external illuminators. All the cool kids on a budget are getting the Dahua IPC-HDW5231R-Z Starlight varifocal turret. It's not...

    Could someone explain why it does not matter PAL vs NTSC?

    When a video camera is trying to display 50 lines per second on a screen that's refreshing 60 times per second then you get horrible rolling distortion. The two big differences now are in the resolution for the subchannel which is slightly better on a pal camera and the multiplier for exposure...

    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

    The link to it said 24w and someone misread it as 24v and thought it was incompatible. NBD.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    It is the standard for all devices regardless of POE. If it will plug into a router or switch it will work on 100m of cable.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Any farther and you may or may not have problems. It's like milk and the date on the container- best before, not bad after. But how far after? You take your chances.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    PoE is good for 100m.

    ANNKE I61DR 2MP (Hikvision Cube Clone)

    Look on the bright side- you'll have video of her beating the snot out of you to play in divorce court. And to show us first naturally...

    Just setup my 2nd 5231R-Z as a driveway cam!

    Do they use those for exposure and gain settings or just for day/night switching? I'd assumed that it was day/night switching and exposure/gain/etc was done by actual image analysis.

    PoE Switch Suggestion List

    Definitely a great bang for the buck if you don't need a full power budget, but who runs a switch full of PTZs or cams with heaters or extra long distance IR LEDs from home anyway? It's going to complicate my next NAS purchase though. I hadn't been planning on getting one that supported link...

    Just setup my 2nd 5231R-Z as a driveway cam!

    I'd think that the next priority would be good coverage of where your wife parks. Put a third cam on the corner of your house to the right of the front door looking out and zoom it in at an angle towards the mailbox. That'll cover the box, her car, plus decent coverage of everybody...

    Just setup my 2nd 5231R-Z as a driveway cam!

    Walk around your car at night. Try the door handles. Then check your footage and see how detailed your face is when your press pause. Ask yourself if you would want to ID a stranger with a similar picture. If not, then zoom in more or add more light. Having said that, you also want to see...

    Just setup my 2nd 5231R-Z as a driveway cam!

    I'd angle up a hair and a bit more zoom.

    Just setup my 2nd 5231R-Z as a driveway cam!

    Landscape but zoomed in more.

    Just setup my 2nd 5231R-Z as a driveway cam!

    There's privacy masking in the camera->video->overlay section but I don't know if it'll change the gain or just not display the bright light while the scene is still artificially darkened.

    PoE Switch Suggestion List

    Definitely has a fan. I just plugged my new one in. Amazon reviews argued back and forth about whether it has a fan or not but I think they blend the 8 port and 16 port reviews into the same pot, so to speak. It's not LOUD, but not silent either. Definitely noticeable even when my CPU cooler fan...

    Just setup my 2nd 5231R-Z as a driveway cam!

    I'd go landscape too. You don't need to see your own plate, you can take his light out of the picture (bright and aimed directly into your lens), plus you see more of the street, although that's fairly well covered already by the front door camera.
