PC Webcam works with iChat and iSight

Before I purchase a web cam for my PC I need to know if it will work with iChat and iSight. Will I need to install any third party software for my mac or PC?

Hi Gene,
You will need to make a choice between AIM and Trillian
The AIM app is free but does not Audio only Chat to iChat users and has a very small pic.
Trillian costs $25 for the Pro version to Video chat but has a Bigger pic and can do full screen. The Basic version can alos Audio only chat to iChat users. Trillian can also join other IM services.
More info on setting up AIM on the PC http://www.ralphjohnsuk.dsl.pipex.com/page12.html and the XP Service Pack 2 firewall. The Firewall will need to have Trillain enabled though it as well if you use that.

Why won't my iSight webcam work with iChat?

I have an iSight webcam and a Power Mac G5. I can't get the iSight to work with iChat, but it works with Yahoo Messenger, although the image is choppy. I have cable internet access, and I am connected to a wireless router (though not wirelessly, but with an ethernet cable). Is the router somehow interfering with iChat and the iSight camera?

Hi Tim,
On a slightly different note does the iChat Open ?
If you click on the green Video icon next to your own Buddy pic at the top of the Buddy List do you see your Preview ?
DO you have any Buddies yet ?
Try Table 1 first after doing what Defcom says

What type of external webcam works with iChat?

Is there a certain type of external webcam that works with iChat or can any webcam do the job?

Logitech Quickcam Vision pro for the Mac was recently released and I am using it with G5 QUAD and OS X 10.5.4 without problems. It is quite expensive compared to other cameras but it has a Zeiss lens and I think a much better picture. Works with evocam also. (evocam is a shareware program to do time lapse photos, or motion sensor movies and webcam stuff). I'm very happy with it.
hth,

RE: Can't get vid to work with ichat

Yesterday my vid and sound worked with ichat and now only my sound. It's frustrating because they both still work on quicktime. I am using a logitech 9000 as my camera. Anyone else have the same problem? Thanks, George

Hi
First have you set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps
In ichats prefs click on video and change bandwidth limit to 500.
Restart iChat.

Which USB Webcams will work with iChat?

Hi,
I'm new to these forums and am wanting to get a webcam, but iSights are no longer available and I don't have the interest or money to get a DV Camcorder.
So which USB webcams will work with iChat?
I take it I'll also have to purchase iChatUSBcam or whatever it's called.
Thanks
Iain

Hi Iain:
There is a list of cams on their website:

The only USB cam that doesn't require iChatUSBCam is the iMage.

Isight not working with skype and tokbox after snow leopard upgrade

Recently, I upgraded from Tiger to Snow Leopard. After the upgrade, I found that my built-in iSight camera wasn't recognized on TokBox. On Skype, it said that the iSight camera was in use by another application (however no other applications were running). The iSight is working with iChat, so I don't know what is wrong... everything was fine when I was using Tiger!

Okay, so I restarted my computer and that didn't work.
Then, I went through the suggestions from the link you posted. I found that the iSight works in iChat and Photobooth; however, it does not work in iMovie HD (exactly the same in both user accounts on my computer). Just like before, the iSight is "in use by another application" in Skype on both user accounts.
I reset the SMC, but it didn't seem to help anything. Everything was acting the same as before I reset it.
I also noticed that my iTunes and my iMovie won't open; they both quit unexpectedly every time I try to open them. This happens in both user accounts as well.
Okay, so it will be simplest to work your issues in steps. We will start with iMovie.
Use your Mac's Disk Utility to repair permissions. Then reinstall iMovie HD 6. Repair permissions again after the installer finishes.
If the version of iMovie HD 6 in your iLife '06 DVD is not "6.0.3", download and install the update:
http://support.apple.com/kb/DL319
If you need to do this update, repair permissions again after the update is finished.
Test the reinstalled iMovie HD 6 to see if it works in more than one user account and post back the results.

Isight not working with ichat

I've ran into problems with my built-in isight camera not working with ichat. It says there hasn't been any information sent in the past 10 seconds and shuts down. It works fine on other programs like Yahoo Messenger and Skype though. Anyone know how to fix this?
Thanks

I asked What router/modem do you have make and model.
Not you OS.

Isight is not working on ichat and skype, however will work on photo booth and imovie.

My isight will not work on ichat or skype, saying that there is no camera connected. isight will work in photo booth and imovie. It shows up in the system profiler. Have tried resetting SMC. Help?

(1) Here is how I would proceed to isolate the underlying problem that requires corrective action.
• Shut down everything.
• Then restart modem and allow its self-test to complete.
• Then restart router or wireless access point (if you have them) and allow self-test to complete.
• Then restart Mac.
• Use  > Software Update... (Update your Apple software if not current.)
• Then test Photo Booth or iMovie with no other apps else running to ensure they still work.
• Then quit your test app and try iChat with no other apps else running.
• If iChat works, quit iChat and try Skype with no other apps else running.
(2) If iChat works but Skype does not,
• Verify that you are using the latest version of Skype that is compatible with your OS X (10.5.8) Mac.
• Update if necessary.
• Then test Skype again with no other apps else running.
• If Skype problems remain but your camera works with everything else, Skype's comprehensive support system should best be able to help you use their product with your system.
Start here: https://support.skype.com/
Or, click this link for help specifically related to Mac video calls.
You can also search or post for help with your problem in Skype's dedicated Skype Discussions for Mac. The Skype users who post there may have already solved the same problem.
If nothing else works, you can even sign in and ask for email help directly from Skype's Technical Support people.
(3) If you still have trouble with more than one app, you may need to use Disk Utility to:
• repair permissions,
• repair your disk,
• or even reinstall Mac OS.
If you reinstall OS X 10.5, use the Mac OS X 10.5.8 Combo Update to return to the latest version in one update step.

Do webcams work with a MacPro? and which mic input?

I have bought a new Mac pro 2 days ago and a web camera: Extreme Webcam SN9C201.
I see a clear and fluid image but there are many video artifacts, like great green and purple pixells, arising from the low part of the image to the center.
Any tip?
I have 2 MOTU audio interfaces. I want to use skype without using the MOTUs.
It looks like the analogic input in the Mac-pro is only for line signal.
So what is the cheapest and easiest way to get some microphone preamplification?
Maybe the Griffin Technologies iMic?
Grazie
Sergio

Hi Sergio,
I have a Logitech QickCam UltraVision and have never noticed any video artifacts. It works fine with iChat and Photo Booth. It has a built in mic but it has been a while since I used the mic portion and don't remember if OS 10.5.1 recognizes it. I will hafta test it.
As far as additional mic inputs go, the Griffin iMic has worked for me in the past on an older G4 PowerMac (don't have the iMic anymore to test it on my Mac Pro). I now use a Plantronics mic/headset combo that plugs into a USB device (similar in size to a USB flash drive) which I then plug into any USB port on the Mac. The headset works great on the Mac side as well as on my Vista partition. Both OSs have no difficulty recognizing the USB headset.
Hope this helps.

USB Camera does not work with iChat

Hello,
I'm having a terrible time getting my ToUcam Pro II to work with iChat. I downloaded the iUSBcam program. That didn't work. I downloaded the program Macam, and copied the proper file into the Quicktime Library (as suggested) and that didn't work. I downloaded IOXwebcam, and got an error stating that it wouldn't run due to the fact that it didn't have the proper security settings. Sigh.
So... what am I to do?
I'd like to buy a webcam that does, actually, work with my 8 month old Mac Pro 4 core mac desktop, but the iSight camera is ridiculously expensive. Any other suggestions would be appreciated.
Brad

An X-box 360 cam will do it although not in that list.
Anything that is USB 2.0 and marked UVC compliant or Vista Certified.
Be Aware some Mac Keyboards do not have USB 2.0 ports.

Getting your router started with iChat.
Appropriate for using iChatAV 2 upwards. Edits have been made for iChat 4
Glossary for this FAQ
Routers: Any configurable device that sits between your computer and the internet link you have. This includes Modems that Route as well as "routers"
Routers seem to fall into two categories
Those that work straight from the box. See Apple Article HT1787
NOTE :This Article has not been updated in content since Jan 04 Only being changed to an Article from the Previous Doc listing
Even then some list that they need tweaks.
and those that do not.
This post will deal with what you may need to look at.
First off make sure your device is acting as a DHCP server. (if you are already on the internet you may not have to bother with this.)
Check in the Tiger System Preferences > Network Preference Pane, in the "Built in Ethernet" option from the "Show" drop down list.
In Leopard the Networks are listed on the left with icons. The Airport Option will need you to access the Advance Button for the Next bit.
Make sure the TCP/IP tab is the 'front' one. You should be able to see Configure IPv4 and it most likely reads Using DCHP. Make a note of your IP address. It will start 10.xxx.xxx.xxx or 192.168.xxx.xxx (the 'x' s will stand for any number between 1 and 255). The range 172.16.xxx.xxx is also a possible value at this point. Rarely used, but it is part of the RFC for Address Allocation for Private Internets.
Your router is most likely to be configurable from your browser. You will need to find the IP address to type into the browser from any Readme or PDF files that came on the install disk or visit the makers website and download a manual.
The Port Forward.com site lists many devices and clicking on one will take you to a list of Applications. This iChat will open an page that will start by telling you the defaults to access the device
Opening or Allowing ports. Several Methods not all devices have all of them.
DMZ (Demilitarised Zone)
This is a less secure setting that basically opens all ports and points the incoming data to your computer. (not helpful if you have more than one computer on your LAN). It can be considered as an extreme form of Port Forwarding
Port Forwarding (also Virtual Server or Pin Holes)
These settings are usually found in an Advanced setting.
You may need to set an incoming IP address (Usually 0.0.0.0 to any outside server), a port that data will arrive on, the Inside computer's IP address (your computer) and the port it will deal with the data on and the protocol it will use.
See this pic for an example of the description above.
In this example shows that on some Port AND Protocols need to be listed.
iChat uses TCP and UDP so some devices will need the ports listed one by one and some settings done twice, once for each protocol. The example above has a "Both" setting
See Apple Article HT1507 Previously Doc 93208 for more information. This is the Tiger iChat 3 list. The same ports are needed for Leopard except for these changes
My Note 2:
On the first link Note 1 under tables in that link would be better if it read:
" 1. All iChat AV traffic is UDP -
except for ports 5190 and 5298, which need to be open for both TCP as well;
and 5220, 5222, which need to be open for TCP only. "
Note 2
GoggleTalk needs port 5223 on TCP. Also note the Server name for iChat 3 set ups
UPnP Universal Plug n Play.
This is a simple Plug and Play type of setting. iChat can find it's own way through a router if the device has this capability.
By Not doing Port Forwarding, Triggering or DMZ and enabling UPnP the application is allowed to control the modem and the ports that are open.
They close after the application has finished with them on a timed basis.
On some devices the number of "hops" (how far away the UPnP can be "seen") can be reduced from a default of 4)
Trigger Ports
Some devices offer a security measure that works by a first or trigger port receiving a data packet and then opening further ports when accepted.
The first port for incoming Video or Audio invites is port 5678.
Pre iChat 4
When you click on the invite window the process moves in to port 5060 (so these will need to be opened by the trigger port) for negotiating the final group of ports from the group of 20 (16384-16403 These will need to open when the trigger says so as well). Therefore port 5678 triggers ports 5678, 5060, 16384-16403. All on UDP. Port 5190 neeeds to trigger port 5190 for both TCP and UDP.
See this variation where only the ports listed above are completed.
The other single ports need to be set one by one in addition. (5220,5222, 5223 5297, 5298, 5353)Replace
iChat 4
The port used in IChat 4 is port 16402 instead of port 5060. The group of 20 ports is reduced to 10 (16393-16402). This is because all the In and Out Audio and Video data is on one port. Other that than the settings are the same.
At this time there is no Info on the ports the Screen Sharing in iChat 4 uses.
Wireless
Here you will have to read around but this Apple Article TA25949 Previously Doc 58514 might be a good starting place.
Essentially whether you are wireless or Ethernet to your routing device makes very little difference to the way you do things.
Your computer will get two IPs from a DHCP server if you are connected by both methods. (iChat does not like this)
Multiple devices
Make sure only one is acting as a DHCP server. Make sure wireless devices are bridged properly.

Projects for iChat and iSight

We love having iChat and iSight, but need projects to use in the classroom. We work with elementary, middle and high school students. Any suggestions?

Hello Susan and welcome to discussions,
Your question is a great one. Sadly its not a question for these forums.
See under Terms & Conditions as for why.
That said, I have a couple of ideas that may be of some use. I can be contacted via my profile.

Check in the Network Preference Pane, in the "Built in Ethernet" option from the "Show" drop down list.
Make sure the TCP/IP tab is the 'front' one. You should be able to see Configure IPv4 and it most likely reads Using DCHP. Make a note of your IP address. It will start 10.xxx.xxx.xxx or 192.168.xxx.xxx (the 'x' s will stand for any number between 1 and 255). The range 172.16.xxx.xxx is also a possible value at this point. Rarely used, but it is part of the RFC for Address Allocation for Private Internets.
Your router is most likely to be configurable from your browser. You will need to find the IP address to type into the browser from any Readme or PDF files that came on the install disk or visit the makers website and download a manual.
DMZ Demilitarised Zone
This is a less secure setting that basically opens all ports and points the incoming data to your computer. (not helpful if you have more than one computer on your LAN)
NAT Sometimes called NAPT and related to Port Forwarding (also Virtual Server or Pin Holes)
These settings are usually found in an Advanced setting.
You will need to set an incoming IP address (Usually 0.0.0.0 for any outside server), a port that data will arrive on, the Inside computers IP address (your computer) and the port it will deal with the data on and the protocol it will use.
iChat uses TCP and UDP so some devices will need the settings done twice, once for each protocol.
See Apple Doc 93208 for more information.
Note:
Note 1 should read:
1. All iChat AV traffic is UDP except for ports 5190 and 5298, which need to be open for both TCP and UDP; and 5220, 5222, which need to be open for TCP only.
UPnP Universal Plug n Play.
This is a simple Plug and Play type of setting. iChat can find it's own way through a router if the device has this capability.
Trigger Ports
Some devices offer a security measure that works by a first or trigger port receiving a data packet and then opening further ports when accepted.
The first port for incoming Video or Audio invites is port 5678. When you click on the invite window the process moves to port 5060 (so these will need to be opened by the trigger port) for negotiating the final group of ports from the group of 20 (16384-16403 These will need to open when the trigger says so as well). Therefore port 5678 triggers ports 5678, 5060, 16384-16403. All on UDP. Port 5190 neeeds to trigger port 5190 for both TCP and UDP
Wireless
Here you will have to read around but this Apple Doc 58514 might be a good starting place.
Multiple devices
Make sure only one is acting as a DHCP server. Make sure wireless devices are bridged properly.
Further Help
I have found that this site (ADSLGuide) to be helpful.
It is British based but I have linked you to the Apple Related Discussions Forum.
Eliminating Problems on my Personal web pages.
The ports and their function within iChat. (my pesonal Web pages again)
This is not a step by step approach. You will have to read around the information about your device.
