No, never use crossover cables...they are no longer necessary..have you tested your injector to confirm its working?
Sorry. I meant to say directly from ethernet port on poe injector to the laptop. POE port on injector is connected to the camera.
You could try this.
Disabling P2P/Easy4Ip and Watchnet/Lechange Pro
Let us know how it goes. I don't know if it will completely stop the camera from trying to phone home.

phew ... I just read thru 67 pages on this thread.
Everyone seems to be raving about this camera and now this has me intrigued. I am in the process of running cat5e cables to camera locations for a new install at my house. I thought I was all set to buy a Hikvision NVR with Hik bullet cams and domes but now everyone here has me rethinking this.
My only concerns is that these cams have zero warranty on them. If they go bad in 6 months or so I'm out several hundred dollars. The $170 price point is very nice though. Has anyone had ANY problems with these? I didn't see anyone post problems in this thread but maybe someone just hasn't said anything yet.

Dahua is extremely reliable brand, reports of any dahua failure on these forums is extremely rare.. and when they do they are usually self inflicted, ie, not properly waterproofing the connections, or screwing up a firmware update.. but bricking from firmware update is much less frequent of an occurrence than Hikvision or anyone else.. they do try to prevent you from bricking it, but shit still can happen.
If you were to buy these cameras from a US Distributer offering a warranty, you'd be paying so much more you could proabibly import a spare camera from China to use as backup and still end up spending less money.
I'm fully confident we wont have another MiniHuisun or Longse fiasco with these cameras, Dahua makes cameras for FLIR/Lorex, Swann, AmCrest, GeoVision and many others.. and they dont just make cheap shit, a Dahua employee was just showing off a $90k Thermal/Visible Combo PTZ here earlier this week...

I have that exact injector and it runs my starlight turret and ultra starlight bullet just fine, it's been running all of my Poe cams for a while.

The 802.3 poe spec requires that it operates on both mode A and B..

If you buy from Andy, he stands behind his product...
The only issue I've had with 2 of the 5 I've bought, is the weather plug for ethernet was the wrong size and wouldn't fit (too small)... it's such an easy work around and if that's the only problem I'm still making out vs other options.

I should have looked at the specific injector, this one works because it uses 48v unlike some of the passive injectors that use lower voltage. It's still a little less desirable than an 'active' poe injector or switch.
@krawaterway take it down and try powering it from a 12v supply to the barel jack instead of poe for testing.
Works with the 12v supply to the barrel jack. Any suggestions on a poe switch that can handle 5 of these bad boys?

This would work: Amazon.com: BV-TECH 8 Port 120W 10/100Mbps Power over Ethernet Switch - Designed for IP Camera Use(Gray): Computers & Accessories
But before you go buying that, what did you use for your Ethernet cables?

Cisco SF300 24PP with 24 ports POE and 2 gigabit upstream port managed switch with the ability to isolate the cameras to its own VLAN can be bought used on EBay for less than a new dumb 8 port POE switch...

Cables that you terminated (crimp/punch down) yourself or premade?
flat pre-made cables can be made with smaller wires and be problematic
bench test it with a short pre-made ethernet cable and your poe injector don't connect 12v and PoE at the same time!
There are good deals like this on ebay, but setting up managed switches is more involved and isn't for everyone. You also have to watch the power consumption on old gear it can be quite high, the particular model you mention has low power consumption.
