Upgrade to HDSDI/HDCVI

[jos123 0]

Hi,

 

Current situation:

DVR 8 Channels

6 Cameras

Video output: Composite (BNC)

Monitors: 3

 

Client wants new HDSDI/HDCVI system from brand Hikvision/Dahua

 

So that means for the screens: DVR > high resolution (1080P) true composite (BNC) > monitor.

Is this possible? If not what are the best options for the monitors? Network + viewer? The client can't pull new cables in his house.

I think it's a common problem

 

Please advice

Use a "VGA to video" adapter, and keep the live view the current way it is now. Quality will not be HD, but if he can not replace the cabling with VGA/HDMI...

Thanks a lot!

I think this is probably the best shot

One more question:

What is max. video resolution I can get true composite true this "VGA to video" adapter?

Hi. To keep the quality then use HDMI over coax (this will also give your customer control with units remote on the monitor)

HDMI over coax

Is expensive no?

The composite video means simply the video quality from analog cameras(VGA resolution, at most). If once converted to a composite video for BNC cabling, then No need to go for 1080P, HD-SDI, HD -analog, or whatever, as the HD resolution and quality would be all gone.

Use HDMI output from your new HD DVR, and find HDMI extendors for hooking into a remote TV or monitor. Or the DVR can output the compressed video stream through its network port. Hook the stream to the NVR to display videos on the remote monitor

HDTVI are available also with composite output

Yes, but it will remain low resolution

Well, if you want analog video, of course it will be low resolution. If you want good quality on the live view, replace the cabling, or spend some money (HDMI over coax).

Yes, this would be the best option when can't replace cable.

SDI (and the other HD over coax..TVI, AHD, etc) give a nice high-def-range image over the existing coax. And I think SDI is the prettiest (though TVI gives those long range capabilities).

 

For the 3 monitors...yeah, it's either:

a) existing coax

a1) - stay with DVD-ish quality for the monitors (but the recordings are still in high-def, so you can zoom in on recordings, etc.)

a2) - use one of the coax-adapters available..which cost money...per monitor (plus the cost of high-def monitors)

b) Re-run the cable for the monitors to use HDMI (or another solution such as HDMI over Ethernet if it's a long range) to get high-def image for the instant viewing. This also means high-def monitors will need to be purchased if the existing monitors aren't high-def).

 

And...

c) hybrid

...did this one for an office that HQ's for taxi service with 3 monitors when we upgraded to TVI for them...

* main monitor near the TVI-DVR - HDMI cable to a new 40" flat-screen high-def TV

* 2 auxiliary monitors (both old-timey-crts) - still used the existing coax to them (using the existing powered-BNC-splitter) so they still had the same regular-definition monitors as before.
