Anyone know of an encoder or decoder for HD-TVI?

Calculate how much it would cost you to reinstall the entire project from scratch as if it were a new system. Remove the parts from your price, leaving you with just the labor portion. Divide the labour by 10 years or whatever you feel is the lifespan of the system. Since half the system is already old you might want to use a shorter lifespan. That will give you a pretty safe annual flat rate for labor since you know that even if you have to replace the entire system over x number of years you'll still come out ok. Oh, and add 10% for good measure.

Just service and support. If you need help getting Dahua from an authorized distributer in Canada PM me and I will refer you. Don't want to start bashing the OEM's here.

Hey Bill, You might find my site helpful (below in my signature). If you have specific questions I'm happy to help.

Dahua and HikVision are both publicly traded companies. They don't have any common large shareholders. Dahua is about 42% owned by Fu Liquan - http://www.forbes.com/profile/fu-liquan/ HikVision is owned 42% by CETC 52 Research Institute, their largest individual shareholder is Gong Hongjia (http://www.forbes.com/profile/gong-hongjia/) he owns about 18.5% of HikVision. Anyway, the two companies are completely independent of one another, at least as far as ownership goes.

Hey bryanviper, I'm in Oakville and I've installed thousands of cameras in the GTA without any issues. Just make sure they're IP66 rated with a minimum -20c temperature rating. I have mixed feelings about D-Link > http://zeecure.com/reviews/cameras/d-link-dcs-7513-ip-bullet-camera/ http://zeecure.com/reviews/cameras/d-link-dcs-2230-wireless-camera/ Axis would be a good choice. If you're on a budget Hikvision is good bang for your buck.

My mistake, I was referring to companies like Milestone, Genetec, Avigilon, Exacq, etc. I'm not a big Dahua or Hik NVR user so maybe someone else on the forum can confirm this - I think, if you buy an NVR with a built in PoE switch that the PoE switch and LAN port on the NVR will act as two different network cards. My experience with Razberi and Sentry360 serverswitches has been that the switch portion of the server is on its own network card. But again, I cannot confirm this for Dahua or Hik.

You can order most NVR's with a secondary NIC, you just need to ask the manufacturer. Alternatively you can usually add your own NIC, either an internal card or external USB NIC.

looks like the IR cut filter is stuck. How does the picture look at night?

You still need to decode the stream. Your monitor won't change that. Of course you do, that's why I would rather use a 1080p secondary stream, than 4K main stream. At some point you're going to want to watch the recorded 4K stream or digitally zoom the live view in which case you will need to decode the 4K stream.

You still need to decode the stream. Your monitor won't change that.

H.265 will play an important role in the adoption of resolutions of 4K+ That being said, I wouldn't get too excited. I had a very frank conversation with Axis at ISC and they indicated that we should not expect to see H.265 in the video surveillance industry till at least 2016. Also, while H.265 could reduce file sizes by up to 50% (of H.264), realistically it will be more like 25%.

4K is a broadcast standard. 4K = 3840x2160 at a minimum of 24 FPS. If it can't do 24 FPS it's technically just an 8.3 megapixel camera. 4K is more meaningful when discussing monitors or TVs since very few surveillance systems need a 8.3MP camera streaming at 24 FPS.

It's unlikely to be a problem. That being said it really depends on the resolution and compression of the cameras you want to use. Can you share with us the model of cameras you're looking at?

No chance unfortunately. Hand it off to the police and hopefully they recognize the vehicle.
