cant connect to starlight :(

[JohnnyM]

I picked up a 5231 from Andy as recommended on here.

It is plugged into a POE switch that is connected to a router. It doesn't show as an attached device on the router (a netgear r7000). I tried to ping the default IP addresses and there is no response. I have run a couple of network mapping tools to see if they can find it. Lastly I opened it up and did the 10 second reset. Still no response from the camera.

Any suggestions as to what else I can do?

Thanks
John

that is because the your pc cant see the camera...the camera and the pc have to be on the same subnet...search, there are many threads explaining how to do it.

sounds like an ip address issue.
Lotsa people connect the cam to the laptop, and power the cam with a 12V supply. Then they change the ip addr of the cam, to be within the address range of your home lan. Then disconnect the cam from the laptop, and connect it to the poe switch and router.

 

[JohnnyM]

It is worth a try. I don't think I have a 12v power supply though. I'll check around the devices and see if I have anything compatible.

 

[Fastb]

maybe connect the poe switch between the camera and PC.

Use Dahua's IP config tool. At the top of the window, click on "Search Setting".
enter 192.168.1.108 as the start and end IP's
Click the round search button.
Then change the IP on the camera to a range that agrees with your network.

OK, an update. I am putting all this an email for Andy as well. I am completely open to suggestions….

I found a 12v 2a power supply, and opened up the camera to check all the connections.

Connected the camera directly to a laptop and powered it via the power supply. I get a green light on the board on the camera, and also if I cover the sensor and turn the lights off I get the IR lights. Encouraged by this [and whilst the camera is open] I tried two different POE switches - lights show with both.

Unfortunately it is still not showing on my network. I tried to reset the camera using the reset button here:

Still not on the network

I have tried the default ports, and searched for it using nmap, jnetmap and by checking the attached devices on the router. I also tried the Dahaua Config tool. It found an NVR on my network, but not the camera.

I am completely out of ideas here. Any thoughts?

There is nothing wrong with the camera...the camera must be on the same subnet as your network....as mentioned in post 2.
What is the ip address of your router?

 

[JohnnyM]

I feel like I am banging my head against a brick wall here. It *IS* on the same subnet. At least I hope it is. How can i be sure if I cant contact it? I know my router is on that subnet. The router ip address is 192.168.1.1.

reset the camera and start over...what poe switch are you using? What cable? did you make it yourself?

Connected the camera directly to a laptop

Bad idea. Unless you have set a fixed IP address on the laptop, as there is no DHCP server, the laptop IP address will revert to a '172.x.x.x self-administered address' and will not be able to connect to the camera.

Encouraged by this [and whilst the camera is open] I tried two different POE switches - lights show with both.

And if the PoE switches were not connected to your router - there will be no DHCP service for the laptop either, so the same result.

Suggestion to try:

I know my router is on that subnet. The router ip address is 192.168.1.1.

I also tried the Dahaua Config tool. It found an NVR on my network, but not the camera.

Assuming the laptop and the camera (with a known good ethernet cable) are on the network as normal, and the camera is powered, use the 4.x version of the config tool : ConfigTool - Dahua Wiki
Use the Search Settings to set the range to 192.168.1.1-192.168.1.254 and hit refresh.
Use the Search Settings to set the range to 192.168.0.1-192.168.0.254 and hit refresh.

Thanks Alistair. I appreciate the comments.

FWIW, the laptop does have a static IP address. I was thinking the same thing as you about the need for a DHCP server. I also like to have as many of my network devices to have a static IP address.

When trying the POE switches, each was connected to a router that was acting as the DHCP server. There are no other devices acting as a DHCP server on the network.

POE Switches tried:

• BV-Tech 8 Port Gigabit PoE+ Unmanaged Switch – 130W – 802.3at – POE-SW800G (up to 30w per port)
• Lorex NVR 6100 (switch mode turned off, not sure the MAXw per port)

When connecting the camera directly to the router I used the wall wart to power the camera. I have tried a variety of cat5e and cat6 cables. All tested and known to be working.

I like version 4 of the config tool - they should have that at the top of the download page, not at the bottom. Sadly it doesn't find the camera. It does find the Lorex NVR should I have it plugged in. So I have confidence in the config tool.

Andy on email suggested checking the connections on the boards inside the camera. They all seem to be correct, and there is no sign of heat or moisture damage.

Looks like I just got lucky with this one.

you will never find the camera when its plugged into the nvr...
use a poe switch or 12v and connect direct to your pc...then you MUST change the pc ipv4 address to match the cameras subnet...try 192.168.1.15..now it will be on the default ip of 192.168.1.108 or the config tool will find it.

 

[JohnnyM]

But the NVR may have been able to find the camera if they were on the same subnet. That is why I tried that.

Fenderman, I don't know what more to say to you. I have done what you suggest. Many times now. Read what I have written. I don't know why the device is not being recognized, and I don't know why you are repeating yourself.

Because you are not doing it correctly
.. there's nothing wrong with the camera...this is 100 percent user error..

OK, I am out. This is going nowhere. I'm deleting my account and I'll find another forum elsewhere. Thanks to all who offered advice.

Fenderman, I wish you luck in life with your level of misplaced certainty.

great dont let the door hit you on the way out...inept users like you who have no clue as to what they are doing is the exact reason dahua and others dont sell to end users. Dont get your panties in a bunch and run crying about leaving...

I have been in your shoes and what he is telling you is 100 percent correct. get a Poe switch to power the camera and plug the camera directly into the computer. Find what the default subnet is for the camera and go into the network adapter on your computer and set a static IP address for the computer that is on the same subnet as the camera. For example, if the camera's default ip is 192.168.1.108 and your computer is set to DHCP it will never find the camera.. go into the network adapter and set it to 192.168.1.xxx and then try finding the camera by IP address from a browser.

I'm a very inept user, seriously...but trying to learn enough for my needs. Some of things you all say send me running to Google just to figure out your abbreviations....please remember sometimes we need baby steps, seriously!

Good, you should go to google and learn if you dont understand something....point is the OP got his panties in a bunch because he was told that he was doing something wrong...that is his problem.
