Re: NVX slow switching between streams
IGMP querier doesn't work unless the switch has an IP address on the VLAN (the SVI referred to).
?
So below is what I have been able to piece together from the network techs, they are not very detailed in their explanations and what they did.
Had the network manager look at the switch and he could see that all the ports were getting flooded with multicast traffic. At first, tried saying it was a Crestron issue. Then I moved everything over to another switch that is using the same version of the IOS as the Crestron recommended (they didn't load the actual bin file from Crestron, but did do all the settings from the help file) from the NVX help file (ver 16, I believe) the other switch is running ver 3, I believe, which is what they are running on campus. To be honest I don't understand how this Cisco IOS works so I just trying to piece things together from the network tech's answers.
I initially had the same problem (slow switching and 1gbs total bit ratemax) on the switch with the Crestron recommended IOS/firmware. They could also see that the IGMP tables and multicast tables(?) were not getting created. What they found was even though the IGMP snooping and querier was enabled they had to add an ip address to the SVI, they are thinking this was because the switch is temporarily running as a stand alone system at my desk. Once this SVI address was added we could see tables being built and I could set each of the 4 transmitters to 950mbs bit rate and they would switch quick and not drop any video or flicker.
Now it's up to the network team to figure out how they're going to make this work on the campus network.
Thank you everyone for your suggestions, at the very least, it gave me things to have the network techs look at and keep them working on this problem.

Crestron zoom integration
Hi,
Can we integrate zoom videoconference with Crestron?. Currently one of my client is using two IPAD for controlling their training room ( one IPAd for AV control and other for Zoom Application). Now customer needs to integrate zoom with IPAD crestron App. All the control from the zoom application they need it in crestron app. Is it possible to integrate? Does anyone have the module?
Regards, Binu

Re: Crestron app - viewing camera remotely
Yes. But I'm wondering how get an rtsp stream to pull up quickly in the Crestron app. I've only seen MJPEG pull up quick. RTSP is super slow, 15-30 seconds, sometimes never until I refresh. What logic are you using?
|
As a CSP myself, I would say you have to find one that you like working with, that works with your style of how your business is ran.? To re-iterate the the last post, each CSP is going to be different, and do things slightly different.? One CSP may be a master programmer, but come off to clients like an A-Hole, and another might not be as good, but is more pleasant for everyone to work with continually.? Another might be the best (or worse) of both worlds!? You just have to to see, and if you like one, keep using them.
From a CSP point of view, I try as hard as I can to be part of the integrator's team.? My client that I'm looking to make happy isn't the end-user, it's the integrator.? I reward integrator's that are loyal to me as well.? If I know that they trust me with ALL their programming, I'm going to do everything I can to be available for their projects, vs another integrator that has 6 other CSP's on speed-dial and has us all bidding on each project against each other.? Guess what integrator is going to get my time if they both have projects coming at the same time and I can't do both?
The other recommendation I would suggest is to talk to them, ask them about their processes, and how they do things.? What they need to quote you, and what they need to do the work.? Whether they come onsite or remote commission.? How followup visits are handled if changes or problems arise.? Most people ask what the hourly rate is and my experience, but that is only a small factor believe it or not.
|
Sometimes there are hidden gems on those rabbit trails....
Asking Pros and Cons isn't a bad question. IMO, all CSPs aren't equal. That includes down to each person in each of those CSPs. I would ask specifically about areas that help is needed.
|
Guys, Let's not get off topic!!
I get it, don't program if you can't install!
The question was "what did you like or dislike, about hiring a CSP?" Aside from them suggesting or re-doing your whole rack" jeez!!
|
There are some very good points in here.
I honestly believe you CANNOT be a good AV programmer unless you have installed for a bit and know how to troubleshoot.
|
Sounds to me like it depends on whether you're paying for just programming or commissioning... make sure the expectations are clear on both sides.? If you hire me as a programmer and expect me to rewire your rack, everybody's going to have a bad time -- there's a reason I stick to software.
?
Sorry, I let myself get distracted with the ¡®process¡¯ description.
?
For the run of the mill installation issues (serial terminations, network/DM terminations, basic configuration issues) that don¡¯t grossly exceed that amount of time we have for commissioning ¨C that¡¯s part of what we expect. The only time
I¡¯ve had to charge extra is when the integrator is grossly unprepared ¨C e.g. show up and the entire rack ?is missing, no power in the building and not enough extension cords and generators to get what I need running ?(yes, I¡¯ve commissioned entire projects
running off a generator in the parking lot), etc.
?
We try to be as flexible as we can but sometimes enough is too much.

I¡¯d say the vast majority of my time onsite is ¡°helping¡± integrators identify cabling or hardware configuration issues. I generally prefer to have the integrator actually make changes mainly for education (¡°oh, if it¡¯s a Sharp¡¡±) and to
avoid potential liability (¡°the CSP was the last person to touch it¡±) ?but I¡¯m not afraid to pull out a tweaker and flip TX/RX myself if the integator¡¯s techs are too busy with bigger items.
?
As long as you don¡¯t drop an LCD on me we¡¯re all playing on the same team to deliver a good working system for the customer.
?
To the OP¡¯s original question it depends a lot on what you¡¯re looking for and the individual attributes of each CSP. E.g. we provide onsite commissioning for every project we do anywhere in the world because we¡¯ve found it¡¯s quicker for
everyone, leaves less dangling issues, and generally lets the integrator¡¯s staff focus on the hardware side of things. In most cases, when we leave the room/building/campus ¡°done is done¡±. ?Some CSPs are very ¡®hands off¡¯ doing everything remotely through various
means and various levels of engagement ¨C that works better for some clients.
?
Likewise, we place a high emphasis on continuing education ¨C everyone we have who would ever touch a system is at least a Silver Certified Master Programmer including some of the relatively few Golds and Platinum programmer in the world;
other CSPs may be more about brute force and sheer size ¨C which may not be a concern for a small, simple system.
?
The biggest thing is to make sure you¡¯re on the same page with expectations from both sides. I always like to ask clients ¡°what problem are you trying to solve?¡± and ¡°what type of user will be using the system?¡± and make sure expectations
are clear.
?
For example, our process is that when we have a idea of the high level of the project, we build a detailed scope that describes everything we¡¯re going to provide for the fixed cost that we¡¯re going to provide it for. The client has an opportunity
to review that and either add or remove from it as many times as needed before we even start ?working on touchpanels. From there we build user interfaces and submit for the client¡¯s review and approval. After Approval of the UIs we build the programming in
our office ¨C so the onsite commissioning is the ¡®tip of the iceberg¡¯. Other CSPs may be a bit more fluid and do more work later in the project.

I do some programming for other dealers. I require to go onsite and go over the site. I also deploy my own code. We carry all needed insurance to be in any building we need to be.

Re: Crestron app - viewing camera remotely
Regardless of HTTP or RTSP the ports need to be forwarded (and probably customized) to view remotely, or using the NVR output stream if it has one.? A VPN would be the secure solution, as you will be opening up a bunch of ports?

Hi All,
I am thinking of hiring a local CSP for a decent sized project, what are some of the pros and cons you guys have seen when you hired a CSP?
Thank you,
