    5231- External IR Help

    Unfortunately, this doesn't work for me. The junction box at the cam isn't large enough to hold an active splitter in addition to the camera's cable connections and all the cable. In addition, the wire run goes past the location of the IR light before it hits the cam by about 20 feet. So I...

    5231- External IR Help

    This does not work if you're trying to pass the PoE along the ethernet cable, according to the seller. I've tried using a passive splitter/injector combination, but this doesn't work because it doesn't step the 48v down to 12v. Alternatively, I'd like to use the active splitter you linked to...

    Compensating for narrow IR lighting

    I haven't done a comparison with faces, although I probably should. I was just pleased that I could see more detail in the margins than before. The external IR is mounted two rafters in front of the camera. You can just see it in the upper left corner (note how the rafter tail was illuminated...

    Compensating for narrow IR lighting

    Okay, pretty much solved my problem with this IR illuminator. I also turned off the onboard IR lighting. Attached are before and after photos. The lighting still isn't uniform, but the edges of the image are brighter than they were before. Before: After:

    5231- External IR Help

    This is the only manufacturer I've found who makes a PoE passthrough IR illuminator. I chose not to try it based on the reviews on Amazon. Granted there aren't many of them so it might be fine.

    5231- External IR Help

    I've been trying to solve the same problem. You're not going to find a splitter that lets you tap the DC voltage while passing along the PoE on the ethernet cable. I had to rig something using a splitter followed by an injector, both rated for 12V DC, plus a DC splitter between the two to...

    Disable onboard IR for Dahua Starlight cam

    I've installed some Dahua IPC-HDW5231R-Z cameras around my house. I'm trying to use an external IR illuminator in place of the onboard IR to get better illumination over a large deck. For the life of me, I can't figure out how to disable the camera's IR while leaving the camera in IR-sensitive...

    Compensating for narrow IR lighting

    I already have Starlight cameras, as I said in my original post. The IR on the Starlight is what's causing the problem. And I don't think your statements about IR range are correct. There are many products out there for illuminating large areas.

    Compensating for narrow IR lighting

    I'd be interested in knowing. My main motivation for making PoE work here instead of using a wall wart is that I've got my security system on a battery backup and it'd be better if the IR illuminator didn't go down in a power outage.

    Compensating for narrow IR lighting

    It looks like my NVR supports IEEE802.3af/at so I expect to have 25.5W available. Good point that the splitter will have to be rated for whatever the camera and emitter need. With 10W for the camera, that leaves 15W for the IR. So if I keep the emitter at or below 1A at 12VDC I should be...

    Compensating for narrow IR lighting

    Yep. This is the conclusion I'm coming to. I still have the issue of how to tap my PoE to power an IR emitter and still keep everything weatherproof. Probably have to insert a large weathertight junction box somewhere along the conduit and place a PoE splitter inside. No rest for the wicked! ;)

    Solved: Problems after repunching down with Dahua IPC-HDW5231R-Z

    Absolutely buy a tester. I was going nuts too before I bought mine. Now I can immediately tell when I haven't punched a pair down right. Also, make sure the punchdown side of your panel is expecting 568B. The panel I have uses 568A, so I have to make sure that I terminate cables at the...

    Compensating for narrow IR lighting

    I can tilt the camera slightly downward and get the rafter tail out of the field of view, but not sure what other reflections you're talking about. It just seems to me that items in the foreground, like the railing, are naturally going to be illuminated more than items further away, right?

    Compensating for narrow IR lighting

    I'm open to this, but I'm not sure how to do it without ruining the clean weatherproof install I've got (see attached image). I'm using PoE, so it's just CAT5e running thru 1/2" PVC conduit into a Dahua weatherproof junction box. Everything's enclosed, and there's nowhere to put what looks...

    Compensating for narrow IR lighting

    I've installed some Dahua IPC-HDW5231R-Z cameras around my house. The beam of the built-in IR seems a bit too narrow. For example, I've got one installed over my deck and while the center of the frame is well illuminated, the left and right margins are pretty dark and it would be hard to...
