Has anyone successfully connected multiple VA11A video interfaces on their PC and able to use multiple cameras thru ActiveHome Pro/iWitness?
-
Well, I finally tried hooking up a VA10A with my VA11A, and found that this will NOT work due to the way X10 has implemented the interface.
So, what X10 needs to build is a video switcher that can be controlled via X10 control. This way they could eliminate those quirky controlled power supplies.
As a bonus, it would allow users to use any camera with X10.
Think I should add this to the "Wish List" forum?

The external X10 video switcher sounds great but the only problem with it is that it is another expensive piece of equipment to purchase. I think x10 should come out with a patch for their software to allow the use of multiple interfaces and the use of foreign video sources.

tjdavj:
You don't need multiple VA11As there are many threads on here about viewing multiple cams if you wish to view more than one cam at a time you need a quad viewer or something similar. ;)
To view one cam at a time in iWitness isn't a problem! Just give them addresses in AHP corresponding to that on their power supply!
check the X10knowledge base (http://kbase.x10.com/wiki/Main_Page) for more info on cams
Or do some advanced searching on the form!
in any case be prepared to do some reading! ;)

By the end of next week I will have 7 cams in the system. 3 - X10 and 4 from another manufacturer. I don't mind manually switching the cams so I plan to feed them all into one VA11A and use iWitness to control them. (6 wired cams and 1 wireless.) For non X10 cams I use appliance modules to control the power supplies. So far with no problems.
I think both a software update and a X10 video controller would be great. I plan on playing with some 3rd party controls but not until the system is all installed and working.

noudo,

Definitely worth the expense for some of us.

I totally agree, unfortunately, it will probably require a total rewrite of the video section of iWitness!

Ok, sorry for the confusion, sounds like I need to explain the problem a little better.
1. I'm not trying to view multiple cams at once, I'm trying to hook up 2 WIRED VK77A Vanguards at the same time, then be able to view them individually in iWitness/MyHouse.
2. The reason I am using wired cams is twofold, I want the highest quality signal I can get, and my wireless network interferes with the video transmission from these cameras.

All you should need is 1 VA11A and a Y adaptor. Plug each cam into the Y adaptor and the Y adaptor into the VA11A. Which ever can is on thats the video iWitness uses. To switch cams turn the one off and the other one on. Does the VK77A cam come with a X10 controlled power supply? If so then in iWitness or AHP or hand held control when you select one cam the others (up to 4 in a group) will turn off so the VA11A only sees one video sorce.

tjdavj :
KDR is right you need a Y addaptor. ;) I'm not sure if the vangaurd comes with addressable power supplies but if not you can use appliance modules for the switching!

None of X10's PTZ cameras have addressable power supplies. They theoretically turn on when selected and off when another camera is selected.. I haven't tried that yet.
Sounds like using a y-adapter is probably the only option I've got, although it will degrade the video quality.
Will give it a try and post when I have the results.
Thanks for the help..

Well, so much for using a Y-adapter.. X10 strikes again..
None of X10's PTZ cameras have addressable power supplies. They theoretically turn on when selected and off when another camera is selected.. I haven't tried that yet.
According to the VK77A manual, when you select any camera (C1 thru C4), it turns that camera on and turns all the other cameras off.
Well kinda, from what I just confirmed, X10 disables the Video sender module, but not the composite video output. To bad X10 didn't spend the additional 10 cents to disable the composite video signal too. Yet another half-a%$ed attempt at cutting corners and limiting usability! :(
Now for the real news..
The VA11A video interface uses a Philips SAA7113H video processor. This chip has onboard support for 4 SWITCHABLE composite video inputs and a video output (for monitoring). So if X10 wanted to, they could easily add 3 more video inputs, a video output, 50 lines of code, a new case and sell a 4 input video interface that would resolve all previous issues for less that $100.00. (As a side benefit, it could eliminate the use of all those addressable power supplies)
[come'on, $50 more for 4 more RCA jacks, a dozen SMT resistors, a bigger plastic case, and 2-3 days of programming, not a bad markup] ::)
Anyway, as if you can't tell, I'm pretty disappointed by X10 yet again, but I'll keep it in perspective. ;D

Is it possible to view multiple cameras at one time with iwitness?
-
That's a tricky question.
While iWitness has a multiple camera viewing window, with a separate subwindow for each video source, There is NO way to view more than one live video source at a time in the window. You have to switch between cameras to view each one.
From what I've discovered so far, X10's real weakness is that they have based their complete video security system around 1 video input and switching video sources to that input. This could be easily resolved by allowing the software to accept additional video sources besides the VA10/11A, but I would be very surprised if this ever happens.

If you use an x10 appliance module (wallwart plugged into it) this will kill all power to the cam when switching thus the video from that cam can't be sent!
Set the appliance module to the camera's house/unit code!
with a little tinkering this can be made to work!
Many are using wired cams in there setup with One VA11A! ;) :D ;D

I use the appliance module on my non-X10 power warts. There is one drawback that I have found.
Due to current sensing of the appliance module I have some wall warts that even though the appliance module is off the wart is still putting out a low voltage. This has caused the cams image to be about 60% darker then it should be. Turning the appliance module on and off did not correct the problem. I had to pull the plug going to the camera then plug it back in to restore the image.
I have not tried to disable local current sensing yet to see if this corrects it but I suspect it will. You could also setup a small nightlight plugged in with the power wart and that would be a visual indicator to let you know if the wart is powered or not.

I wish it was that simple.
The main problem with this approach is that unlike the generic X10 cams, the PTZ cameras go thru an initialization procedure every time they are powered up. This takes about 10-15 seconds, and the camera is unusable during this period and when done the camera is centered and zoomed out.

Found this on multiple vanguard cams... You may have seen this already
Question
How can I hook up and control multiple wired Vanguard cameras?
Answer
You will need a quad processor or multiplexer; you can order a 4-cam color unit for $210 by calling 800-675-3044. Hook all your Vanguard cameras into your multiplexer using the RCA video cables, directly from the wired output on each Vanguard camera. Set each Vanguard to TRANSMIT ENABLE (yes, this does not seem logical, but do so anyhow.)
Each camera comes pre-programmed as camera 1 (C1). The first camera you set up will stay C1. Program the additional cameras as C2, C3, and C4:
Pick the camera to use as C2.
Set the mode switch on the bottom of that camera to Program.
Press C2 on your remote control to set this camera to C2.
Set the mode switch back to Transmit Enable.
Repeat these steps for the rest of the cameras, using C3 for the third camera and C4 for the fourth camera.
When you turn on your TV/computer, you should now see all four cameras live on the screen at once. When you press a C1, C2, C3, or C4 button on the remote, the remote should control that camera exclusively.

So it looks like X10 is saying the only way to get multiple Vanguard cams is to use a Video Processor.

I have a unit that switches 4 sources either no or nc and it uses x10 commands. There are 4 relays in the unit.
The only extra thing you need is a TW523 to interface the unit with the powerline.
email me if you are interested in the unit, it is for sale. $100 Cnd.

I have video surveilance software that monitors 4 cameras, (Can monitor many more with a multiplexer) detects on screen motion, records video, acts as a server, can be viewed and controlled via my LAN or via the web.
Right now, I feed just one non x10 surveilance camera into the USB adapter and monitor it with AH pro.
If my 4 camera capture card had a RCA out signal, that would be cool, but no!!!
It would also be cool if AHpro could tap into my 4 camera video capture card.
Just day dreaming. ;D
