Basic Fault Finding On IP Cameras

In this article we are going to be exploring some common issues with non functioning IP cameras and how to resolve them step by step.

Cabling Issues

Always ensure that the RJ45 cable connector is properly pushed into its port. (RJ45 cable is the wire that runs between the IP camera and the network.) Check both ends. A broken release pin on the RJ45 connector is a common thing and can cause the cable to pull out from the network port.

Check the network ports on both sides for green / yellow flashing leds. This will indicate that the IP camera is running OK and has a network connection. If you don't see any network leds flashing this may a cable issue. A network cable tester will help you identify further if the RJ45 cable is good.

IP address testing

If you know the IP address of the IP camera try pinging it using the Command Prompt from a Windows PC or Laptop. Open Command Prompt, type ping YOUR IP ADDRESS example ping 192.168.0.50 and press enter. A successful ping will show as per image below. This will indicate that the IP camera is on and has connected to the network successfully. (While performing the above tests we are assuming that the IP camera is powered on and is connected to the network). From a Mac computer the test are similar using the Terminal tool instead.

If you didn't get a successful ping and instead you got Destination Host Is Unreachable, you may have entered the wrong IP or the IP camera's IP address is on a different range. For more info on IP addresses check out our article on IP Addresses & Subnets.

If you don't know what the IP address we can use an IP scanning tool to locate it. Download and install Advanced Port Scanner. Once it is installed, run the program and you will see the following screen.

From the top toolbar click on the blue IP Icon. This will automatically set your IP scanning ranges. Then click Scan. Once it's finished scanning it will list all active IP address on your current network.

As you can see in the above screenshot the IP Scanner has located and listed all active IP addresses and their ports. The scanner has found 2 IP cameras on our network. IP address 192.168.0.50 and .51. Open up a web browser and enter the IP address in the address bar. It's best to add http:// before the IP address as sometimes an installed web plugin may override your address and treat it as a search query. If everything was successful you should now see the login page for you IP camera. If you are having problems logging into your IP camera check out our article on IP Cameras Login Issues & How To Resolve Them. This article also explains how to factory reset an IP camera.

If all of the above fail try factory resetting the camera. Also keep an eye out for IP conflicts. An IP conflict is when you have 2 devices on the same network with the same IP address. For more info on IP conflicts check out our article on IP Addresses & Subnets. If you have any questions or would like any further advice please leave a comment below.
