help! advice replacing 4ch dvr

[Gesualdo 0]

I'm looking to replace my dvr and upgrade from analog to ip cameras. I need a hybrid dvr that will work 4 channel real time d1 analog now and change over to 4 channel realtime ip megapixel cameras. I am not networking in the future and trying use the same siamese cable that is in place.

 

what do you recommend?

 

Also need playback from backup to be full resolution, got burned with old dvr where playback is cif only.

Thanks

Do you have a preference regarding what platform you get to use? Since I am more familiar with the embedded (stand-alone) units, I'll elaborate on those.

 

Currently, the selection of hybrid NVRs is quite limited for embedded devices. I know of one 4 analog/12 IP hardware hybrid NVR, but it only does 480 CIF. In other words, you will get your D1 4 channel real-time recording, and it stops there. If you need to upgrade to megapixel (how many megapixels?) later, you WILL HAVE to remove the 4 analog cameras and STILL NOT GET REAL-TIME for megapixel recording. You will probably get 10 to 15 PPS at 720P at best.

 

Also, what is your budget? Why are you upgrading to a 4 Channel D1 and THEN to Megapixel? Why not just upgrade to Megapixel from start?

You will have to re-run all the network cable because IP cameras won't be able to use existing coax cable.

 

There are megapixel cameras and DVRs that will work off of existing coax cable - as long as the existing cable is true 95% copper braid cable - all you need to do is remove your old cameras and DVR, replace with new ones, power them up, connect to the same coax cable, and then you're done.

 

If you post your budget, then perhaps I could recommend you specific brands and models.

I need to at least replace an analog camera right away. I can use the existing cable as it is 95% copper braided 18/2 siamese, and I do want to go megapixel on at least 4 cameras, 2 megapixel each. I can only switch 1 camera at a time due to budget for camera and dvr at once.

 

I will appearently need the converters to ip over coax, but will they fit in a electrical gangbox? Is there one that will still use the power siamese side or is it only over same cable?

 

Will I need some other device to connect the ip camera to the dvr? I am not looking to network the cameras. I do want 30 fps true D1 playback on existing analog from recorded and live view for each camera. full 1080 from megapixel.

 

I'm not sure what prices are available. I do not want to go casino prices nor cheap low end, around $1000 or less, if possible.

Why not go with HD-sdi hybrid dvr so you can use your analog cameras and than just upgrade your one camera with an HD-sdi so you can get your hd over coax?

what are the problems and limitations of the camera and recommend a dvr?

huh?

Aside from higher price, What I am finding is that the HD-SDI dvrs is they can only handle 1 or 2 HD-SDI cameras and at a lower framerate and resolution and are limited to 1.3 megapixel cameras. am I wrong?

 

I do not find name brand dvr's and suppliers, I must be missing something in my search. My sources are online only.

I like the idea but have not found the applicable units yet. What do you suggest?

 

And thanks for your responses I had all but given up on getting a response to this thread.

Hello,

 

There are some real-time DVRs for HD-SDI, but limited to 4 channel (with my limited knowledge). I believe that the market will be saturated with real-time HD-SDI DVRs after ISC West 2013.

 

Having said this, the real-time DVRs are limited to 1280x720, which the market calls 1.3MP, but in reality, it's really 0.9MP.

 

Anyways, good luck with your upgrade hunting.

Some 4 ch models already show up with 25 fr per ch at 1080 resolution

just cost more

Most (but not all) require you to power both sending and receiving units. Most tend to be a bit on the larger side - might fit a dual-gang, but would need a single-gang to be fairly deep. Keep in mind these things normally start around $100/set and prices go up sharply from there (realistically, plan on $250-$300/set).

This is a 1.3m IP camera during the night. I'll try to post one during the day tomorrow. Right now, it's just for

viewing until we set up a PC for remote recording. In full screen especially during the day, the colors and clarity are amazing. At night time, there is no noise and plenty of detail. I've put the 1.3mp picture side by side with a dvr

using D1 and in small screen there is not much difference. But in full screen and zooming, the 1.3mp camera

is astonishing. If you have the budget for it, definitely get megapixel cameras!

thanks everyone.

This is driving me crazy because I basically need to decide for someone else. let me run a couple of scenerios by you to clearify my understanding.

 

1- If I use ip over coax: I will need IP camera, hybrid dvr, and converters to power and convert signal to coax and back to connect to dvr. but gain more cameras, higher resolution, image size, and frame rate depending on dvr. But, more expensive connector/converter and possible converter size problem on camera end. using octagonal box at present for connection point.

 

2- If I use HD-SDI: I will need HD-SDI camera, Hybrid HD-SDI DVR, existing cable. I will have few cameras (maybe not enough), limited picture resolution and size than IP, slower speed, but at higher cost

 

3 If I simply replace with analog camera: quick fix, easy, relatively cheap, but low resolution, low size. poor playback quality at present and not sure higher quality camera is cost effective solution.

 

4- All IP: replace everything at once. Cables, DVR, 4 cameras.

 

I will probably need to replace the DVR eventually- within year or two and really trying to not run new cable. and option 4 really isn't in the budget.

I can't figure out which way to jump what equipment to buy.

Rewire with Cat5e and your total cost for IP drops by about $1000. Plus, you can use your analog cameras with it initially and then upgrade easily.

WOW. What make and model is that camera?

OK but where to buy/find price? I'm in the US and searched cant find...

They have them on eBay right now

[Brent1971 0]

OK cool I'll check it out thanks! (eBay hadnt come up in my search).

 

Also, please see this video:

 

And info summery on CCD and Progressive:

http://www.avsipcctv.com/content/why-mpix

 

He makes reference to CCD is better for mottion, and ESPECIALLY Progressive scanning! See the examples of stop action. Anyone know where to get these cameras or if they as good as they appear?

 

Any other suggestions for 2-5MP IP cams for my home system? Keep em coming I am learning here...

Cool thanks. Great price point. It is CMOS which the Mpix video says is not as good at might but I can live with that. What I wonder, is this Porgressive scanning and how does it work on moving objects? The Mpix stops them with incredible clarity (But I cannot find an Mpix reseller or price yet, waiting for an email back on that)

CMOS cameras by nature are progressive-scan, AND are direct digital-to-digital output (addressing the Mpix video's "digital-analog-digital" claims).

 

The vast majority of megapixel cameras you find will use CMOS sensors. There's nothing inherently wrong with it.

The biggest advantage of progressive scan is that the captured pixels are actual rather than two interlaced together, hence resulting in a blur-free moving images. Of course, this can be affected by the video compression mode, but the point here is that progressive scan will provide the actual TV lines it claims to offer.

 

Think of this like the upscaling (interlaced) of DVD players to 720p or 1080p whereas Blue-ray (Progressive) players output true 720p or 1080p. My reference may not be 100% accurate, but I hope you get the point...?
