Best HDcctv camera?

Recommended Posts


Was never overly impressed with Neverfocus's DVRs or analog cams...

 

I don't know if anyone else here has used HDcctv at all... it's kind of an overrated niche technology.

HDcctv is the next wave of camera technology. It is a digital signal over coax. This falls between IP and Analog there will be some advantages with HDcctv. You can get up to a 2MP camera from Everfocus and use traditional wire methods using coax. They do not work over cat5 or cat6. HDcctv cameras and recorders will be standardized so any HDcctv camera will work with any HDcctv DVR.

 

I had the Everfocus rep come to my office and give me a demo. The indoor image looks awsome but the cameras have a hard time with different light conditions. The night time image is not very good and the cameras are not WDR. I would wait another year or two before I used the HDcctv technology.

So far I noticed that any HD-SDI works well between each other

so the ? is why do we need HDcctv

 

Just got first sample of HD-SDI

and so far pleased

sold 3 sets in about 10 min

Thanks. I'll remember that next time I'm installing digital signage (which is never), but not when installing CCTV cameras...

Hi. How are you?

 

Whats the advantage over HD-SDI? Difference?

 

Thanks.

Hi Carl. Have you compared HDcctv vs. HD-SDI? What was your opinion.

 

Thanks.

Thanks. But I already did search. Want to hear other opinion also...

If everything was from Google why do we need CCTV Forum? Why do we need training? Why do people go to college?

 

Just google it...

 

Lets hear what Carl has to say if he wishes to express his opinion. Also intrested in your opinion Alex?

Looking into hearing other opinions.

 

As you might be aware there is a theoretical side and a practical, implementation, marketing, etc., etc. side on how a technology, idea, etc gains traction.

 

Its always interesting for me to hear, read other opinions... Do you agree?

 

^ is your company looking into HDcctv vs. HD-SDI products?

The company has been a Bosch dealer for 25 years. So really we have been a Burle- Phillips- Bosch dealer for 25 years so we use a lot of Bosch.

 

Bosch has been slow to the HD market so I use Axis Comm cameras when I need HD or MP cameras. We do a lot of Federal and high security locations so if it is new to the market a lot of our customers will not approve it.

 

I am not 100% sure what you are referring to as HD-SDI products. A lot of manufactures have different names for the same thing.

SDI is a very old broadcast standard, I don't know that I'd call it "next wave".

 

It is a digital signal over coax. This falls between IP and Analog there will be some advantages with HDcctv.

Which are what, exactly?

 

You can get up to a 2MP camera from Everfocus and use traditional wire methods using coax.

That's like selling someone a car that can run on leaded gas - nice idea, but obsolete. Coax is a limited-use cable; UTP is far more flexible, versatile, and frankly, cheaper. There's no compelling reason to wire an installation with coax just for SDI cameras, especially when SDI doesn't go past 2MP.

 

They do not work over cat5 or cat6.

That's a major disadvantage... since analog cameras DO.

I wouldn't totally agree with Soundy, because he's being a bit unfair about the whole situation.

 

First of all HD cctv sistems can offer simplicity IP sistems lacks. Just plug it in that's it, no networking knowlage needed, no protocol compatibility needed for different developer HD cctv cams and HD DVR.

 

Soundy was true, SDI has limitations 2 MP, but since this technology is rather new, there's a posibility to have even higher resolution in the future. For example, not to long ago, 3G SDI interface was developed, enabling to 1.485 Gbps.

 

Most of installers will agree that too much MP is not an awnser. And the optimum is about 2-3 MP, because IP cameras with have 5 MP or more, are absolutly blind at night and have a low frame rate per second.

 

But the main advantage of this sistem is that praticaly has no latency, could be a solution in some precision needed places, like shops, gas stations, banks. Even more, HD cctv can have 60 f/s, that make it even better for this situation.

 

So in conclusion, I'd like to say that HD cctv can find its place in a market for sure.

HD-sdi will be good for trunk slammers and install company's that are afraid of IP and at this point if your not learning IP you will be obsolete in a couple of years.

 

My main issue with HD-sdi is design flexibly, you are again limited to blocks of 4,8,16 and you have to use coax home runs with distance limitations and no wireless options.

 

Also the man in charge of HDcctv is a condescending a-hole.

I calls'em as I sees'em.

 

Soundy was true, SDI has limitations 2 MP, but since this technology is rather new,

SMPTE 292M (HD-SDI) was first published in 1998... when the vast majority of analog CCTV was still using VCRs. It's not new.

 

But the main advantage of this sistem is that praticaly has no latency,

It actually has ZERO latency. However...

 

could be a solution in some precision needed places, like shops, gas stations, banks.

Having installed systems in a couple hundred gas stations, I can tell you right now, zero latency would be of zero benefit. Consider that 99% of the time, in a retail situation, you're going to be viewing recorded video rather than live - an "introduced latency" of hours, days, weeks, or even months. If someone IS viewing it live, they're probably sitting in a back office, and an extra half-second between when something happens and when they see it isn't going to make a speck of difference in the time it takes them to get up off their arse and trundle out to the front counter.

 

Even more, HD cctv can have 60 f/s, that make it even better for this situation.

At even higher storage cost. 30fps is overkill in the majority of situations. 60fps is pointless.

 

So in conclusion, I'd like to say that HD cctv can find its place in a market for sure.

I never said it didn't. But it's a niche market at best. The benefits offered are *relevant* in only very limited situations.

It's new, if you take a surveillance into consideration we are talking about surveillance cameras, right Soundy?

It still proves my point. Latency - bad, no latency - good.

 

60fps is pointless.

 

Pontless in normal movement conditions, agree. But in extream movement conditions it's critical.

 

Perhaps it will be niche market, but we are just trying to get a benefit from it. I say it has potential.

Latency is not inherently "bad". Latency is the very nature of RECORDED video: it happens now, you see it later. That's the whole point.

Soundy you are installer i see, you dealed with HDcctv surveillance systems?

We are planing to try it out it soon, that why I ended here in the first place

Maybe you know what are the weak technical points of this system? common bugs and such...

 

Thank you in advance

Hi Carl. Have you compared HDcctv vs. HD-SDI? What was your opinion.
We can't use either one so I've never even tested them. I've had a couple of vendors approach me (one for HD-SDI and one for HDcctv), but my first question to any vendor is can they demonstrate the product on our system.

 

For our purposes, neither system is ready for casino use: it won't work with our cable infrastructure (70% UTP single-pair w/baluns - 30% coax with many runs far longer than 100m), it won't work with either our matrix or our NVR and it won't display on our monitors.

 

In essence, what's the point?

HD-sdi = all of the disadvantages of DVRs with some of the advantages of HD IP.

 

Biggest advantage of HD-sdi is zero latency

Actually in my line of work, zero latency would be a plus. However, as I stated above, there's no advantage to a technology that not only requires we replace much, if not all, of our infrastructure, is not capable of seamless integration with the rest of our system. No matrix switches or recorders capable of handling >1000 cameras. No ability to display on tens of monitors, etc.

I can see the biggest benefit for you being in PTZ control, especially as this is one of the main areas where latency in IP cameras IS a problem. On that note though, I'm currently bench-testing an Axis Q1604 (their new highly-touted low-light/WDR toy), and I gotta say... latency might be MEASURABLE, but it's practically UNNOTICEABLE unless you're actually looking for it. I can point it at my screen, then watch on the DVR - moving a window on the screen, it's only intermittently that I can actually see a delay on the DVR.
