video over Power over ethernet

[cctvlad 0]

Hi there i want to say thanks for helping out before and my installation is going smooth(2nd installation) only thing is the customer wants to see his cctv on his TV in the house.

I have tried to use a vga splitter to a wireless AV sender but it didnt work im thinking it may need a VGA card with a tv out.

 

the question i need to ask is that i have two Homeplugs (POE) and i want to be able to transmit video through this e.g

pc tv out - > home plug 1 --- transmit video ---> homeplug 2--->house TV AV port

 

How do i get this to work properly with out the extra cost.

 

i probably will do wireless for now though but im sure that POE is better quality

 

POE seems a good techology i want to be able to use them for analogue cameras but i also dont know how to do this too.

 

this forum is pretty good lot of good guys here.

 

anyway im trying to start up a CCTV with IT solutions business hell its in demand and it just comes to you.

Are you using a PC based DVR, or a stand alone DVR?

 

I thought you would have a composite video out?

[cctvlad 0]

pcbased dvr but the point is to transmit the VGA over the POE or Wireless.

 

it has a a composite out but i cant use it becuase i have an IP camera as well as a dvr setup. as both cant come through the composite out it will be both been seen on the pc desktop so im trying to transmit the desktop to a tv.

I'm sorry. My mistake. I did not realize that your TV had a VGA input connector.

[cctvlad 0]

my tv doesnt havea vga connector.

 

building one --->pc tv out card ---->buiding two---> TV scart.

 

two buildings 10metres apart

 

i want to transmit through POE

 

how do i do this with POE

 

it has to be a wirefree solution(homewireless av senders are crap)

dont worry about scart its just a audiovideo input.

 

bottom line is how to i transmit video over power over ethernet.

 

 

 

help on this would be appriecated?

I would assume you would use an analog to digital converter, and at the other end use a digital to analog converter.

 

composite video goes in to a device that gives you an IP output, then you go through the device that gives you the ethernet over power. At the other end you would use your ethernet from the power, and connect it to an IP to analog converter. Analog signal to your tv.

know where i can get one cheep?

 

hear about the bridge in usa??? crazy!

What DVR Card are you using? Does it have a DSP (RCA) Output for the video only? Do you need total control of the video or just to view a duplicate of the DVR's video?

 

Why would you be interested in POE? That is sending POWER over the Ethernet, not Video.

 

Are you talking about sending it using POWERLINE devices? Such as how X-10 does it? If so, then just look for one of those. Too many issues with that stuff down here so personally I cant recommend anything.

 

Here is one idea though:

http://reviews.cnet.com/Corinex_Powerline_router/4660-3319_7-6239462.html

 

Then use an IP Encoder (Video Server) and an IP Decoder on the other end, 1 channel only, high res, and output to the TV like that.

 

Other Option .. depends what you want to spend .. Setup Wireless Video Transmitter (some call it analog wireless) on the DVR side, setup high, and better yet, in its weatherproof PVC enclosure on the outside of the Building, line of sight, to the other building where a receiver is. Video from there goes to the TV using RCA. That is a typical wireless CCTV setup. Check out VideoComm.

 

Next option .. depends on the DVR, if it has a client based program you could set up a mini PC on the TV side and just run that program on that, using a Wireless Router just send it over that route with a wireless access point. You can get away with a simple enough Linksys router and access point to save money. Though the PC will still cost extra, and depends on how good the DVR's network software is.

thanks lad the ipserver and ip decoder is the one i was looking for. cheers.

 

ive had a thought if i had a pc based dvr with remote viewing enabled ...

if i got a network enabled standalone dvr connected to a tv at that remote location.

 

would this also work?

 

btw i thinkt he standard analogue wireless setup is the cheapest method.

 

im interested in sending video over POE in order to save installation hassle.

Not really, they are both DVRs so you can only access one or the other. You would want the client side at the TV and the Server side (DVR) at the other end where the cameras are. I made some custom software like this for the Geo DVRs, but havent released it yet as rewriting all the main code. It loads in the BBlean shell (not explorer.exe, no desktop etc) and once you set it up once, it auto connects when you power up the PC .. it will stay running until your turn it off .. very basic version .. connection drops the video just goes or if one camera looses video that goes .. but once it comes back the video comes back up as it auto reconnects.

 

But if you have the decoder on the Tv side, just output from that direct to the TV, and you dont need any client software or another PC.

interesting interesting!!

 

so an ip decoder connected to a router can do this at the client tv side??

 

or a mini pc with a tv out? you could do a lot more with the pc anyhow.only thing would a pc tv out be good quality on a tv??

 

is that right enough??

 

good luck with the software mate

Ive never personally used the Decoders, just going by theory from research. Basically you encode the analog video (output from the DVR) using a 1-channel IP Video Server (Video Encoder), plug that into the router of your choice, then on the other end, from the access point, you plug the appropriate port into the 1-channel IP Video Decoder, which decodes the IP video to analog for output to any composite input such as a DVR BNC port or TV's AV input.

 

Or ..

 

If you already have a DVR and if that has client software for your PC, then optionally just use a PC (mini or not) on the TV side and run that software when you need to. You would probably want to just stream in lower res and H.264 and also make sure you can set a default site for the software to load, and place that on start up. If the software does full screen then even better. use the TV Output from the PC's video card to connect to the TV; eg. S-Video.

If you do decide to use ethernet over powerline you will have to look at the wiring going from building one to the pole, and the wiring going from building two to the pole.

 

This system will work as long as there is not a transformer between the power lines of the two buildings.

hello lads okkk I think i have a solution to the tv out to the house instead of a wireless solution.

 

beside the computer int he officce there is a CAT5 cable run to the house for a telephone extenstion but only a few pairs is being used.

I was thinking I could attach video buluns on each end one at the tv out from the video card side and one at the TV side. would this work...its about 10-12 metre cable run.

 

would this be efficent???

You could also use for instance a digital modulator and jsut take the signal from 1 camera or several and give each channel or from a quad to a channel on his TV, if he have several TV's in the house and they are all on the same signal system then he can have them on all the TV's in the house!
