This may be true but you still have to record the full image, which in my understanding is a very bigh bandwidth. Most video is recorded and not viewed so the live efficiencies you have detailed still do not reduce the bandwidth. Just the PC processing power required and the bandwidth on that part of the LAN. Does the video stream from the camera or via a server for down scalling or multiple clients at the same time.

The client should call for a shoot out and understand their own requirements. Avigilon is good if you want massive resolution and short storage times (or huge capacity hard drives) I have 1 site that runs both Indigo and Avigilon on the same system for 2 different uses. IndigoVision is recognized for an excellent user and technician friendly interface. Most CCTV applications do not need the 3+MP resolution and in my experience do not have the bandwidth to support it and as such many of the MP cameras are not programmed for their max resolution. Also many can not provide full frame rate at full resolution. Do a shoot out and then decide.

HD means the HD standard of 720p or 1080p. At this stage these fit most peoples requirements and as such I can not comment on the Avigilon products up to 16MP. I can only say that JPEG2000 is not an industry standard, which is what Indigo try to adhere to and is why we produce H.264 encoding, which is the TV industry standard and has a lot of room t be further enhanced while remaining with in the standard.

guys, My HD is lower bandwidth than many others 4CIF. Have I not shown this and the resolution speaks for its self. My 4CIF is less than HD and CIF is less again. What more do I need to Do to convince you?

please comment on my post re my expeirence with wireless IP video http://www.cctvforum.com/viewtopic.php?p=98719#98719

In my experience, Pelco wireless solutions fall over for 2 reasons. 1 - Bandwidth is too high 2 - in my region the systems lock up possibly due to the ambient temperature. I have replaced 2 Pelco wireless point to point systems with IndigoVision, where the wireless product was retained (SmartSight) and this fixed most aspects of the system. I have also provided several larger scale wireless systems in councils, again with IndigoVision but instead using WaveSight links. The reason bandwidth is so important is MPEG4 and H.264 video streams have no periods of no data and the video can not be further compressed. A link with a stated bandwidth of 54Mbps has a half duplex rate of 27Mbps. When you transmit 'normal' computer data, there is typically the ability for the Tx to apply compression to the data just like ZIP would, reducing the file size. This take processing time. Also in computer data you would normally send in data bursts. not constant streams. These bursts give the Tx time to compress and do other tricks to the data before transmitting it. So when you send video, the TRUE through put of a RF link is often as low as 3Mbps. OK next the video we send may be only 2.5Mbps but that does not take into account the TCP or UDP overheads. so add 15% to this for TCP. So we are up to 2.8Mbps and there are often some other data process in the background as well. If we use a link designed for CCTV such as the WaveSight, we can get much higher throughputs. I can vouch for 21Mbps. You can still come unstuck if you try to use a multi point Rx instead of a Tx Rx per link. What happens there is every link is repeated out to all other links. So the 2.8Mbps above in a 3 link multi point system suddenly becomes duplicated on the other links (in the up link direction). My recommendation - use point to point for every camera and use IndigoVision extended temperature models. This will use 50% less bandwidth than many other products for the same measurable resolution.

apart from the top line others are 25ips 4CIF. As far as pixels go, yes they can limit your best resolution but for most codecs out there they never produce the full capability of the pixels in measurable resolution.

OK, For all the skeptics out there I have attached a bandwidth profile of the 9000 product based on H.264. This shows the difference of 4 products readily available in the market. It is well documented that IndigoVision uses 50% less bandwidth than most other products for the same RESOLUTION. Not I am not referring to PIXELS. Actual visual quality of the image as a pixel count says nothing! The 720p HD camera is based on the same compression as the 9000 series. I have also put a clip of the 720p HD camera up at http://senduit.com/c3bf63 for 1 week only. It is converted to MPEG4 as the native H.264 is not as easily viewed with out downloading viewers. This clip according to my software is averaging 650Kbps at 720p resolution.

it is wrong. MPEG4 and H.264 are variable bit rates dependant on scene. I can actually produce a HD image of 720p at 320Kbps average. You can not measue these as a KB file size. Any product that does is not implementing the protocols properly and is only sending I frames, which is no different to sending JPG's 30X a second.

OK My mistake, that was VCD. However A DVD is always 720x480 (unless you live in PAL land). As stated here, pixel count does not state resolution. http://en.wikipedia.org/wiki/Image_resolution You can have a megapixel camera with worse resouldion than my CIF cameras. I will post a clip when I find a good CIF/4CIF of the same scene from my product. Seeing is believing

You show a missunderstanding of video. Did you know not all DVD's are D1. many are CIF. A full screen CIF image is almost as clean as a 4CIF image when viewed at 756x582 resolution. This is for Indigo anyway. I know many others will not be the same case It is only when you electronic zoom that there is a real difference to 4CIF. If you wanted to stream at 4CIF 30ips, i would start at 512Kbps. We can record at 4CIF on site and stream live at CIF, giving the best of both ends.

Yes but at what bandwidth? IndigoVision does all this and requires no servers at all in the system. We would require 32Kbps for the audio and dependent on image quality, 128Kbps for the 30ips CIF video. We actually guarantee the 30ips regardless of what else is going on in the codec. No dropped frames or image tearing. I did not realize how much this meant until recently doing a shoot out against DVtel (OEM encoder) where their image could not be maintained while controlling a PTZ for more than 3 seconds. Even though they used 10Mbps and we used 4Mbps.

I have done thisa couple of times in a medical shool in a University. I used the IndigoVision products, with an external microphone. high quality ceiling mount mic and local pre-amp. Works really well. Full PTZ from the lecture room, which was 50Km from the medical training room. Here is a similar (not mine) that has had a press release done. http://www.indigovision.com/business_education_medical.php

I have a full solution to do this with IndigoVision. the analogue cameras are connected to encoders and the new IP cameras are IndigoVision. The serial output from you POS gets wired to any camera or encoder and it will overlay on the image or along side it. Key events can be mad to create index book marks such as no sales. Later on you can Search by operator, item SKU, transaction number.... Basically any thing the POS outputs. What country are you in? I can connect you to a local

you need to decode it in some way. A PC input on the TV would be one way and have a PC running. My product - IndigoVision has a receiver module that will decode back to composite video.

www.alfatron.com.au I hav used plenty and they work realy well. They have a tri-state output controlled by the RS232 RTS pin

I may be seen as out of place in this forum but I would not touch a PC based system This is based on numerous bad experiences. Andover Controls - Integral Tech DVx & DVXi Keep failing Pacom IDR2016 Keep failing I have seen plenty and they are just PC's in most cases. Not servers or custom purpose build hardware. Please correct me but they just dont have the reliability of a hardware DVR.

it is most likely the sync pulse is too weak from the camera rather than the DVR. It may only be one camera but it can upset some DVR's on other inputs. I have seen this before. In theory, the sync pulse should not change based on light conditions but the AGC in some cameras seems to affect this

IndigoVision will use 50% less bandwidth than others but is not a DVR. Its an IP solution. No reason why you can't just install all the gear in one location ussing 10channel encoder racks. As an example you can get real time from 1 camera and contol PTZ at 128Kbps. I have some customers viewing at 2ips on 32Kbps You can also record on site in 25ips 4CIF at 4Mbps h.264 and stream off site at CIF at any other setting you like such as 5ips 64Kbps

Thats a loose question. Do you mean as a solution (software and hardware)? The camera it self Are we talking mega pixel, PTZ, HD?

Yes VHS and Beta did compete and VHS won. That is why we are supporting both. One will come out on top and we will be compatible with it. Axis and Indigo demoed the functionality of the OMVIF open standard at ISC West last week. ALL Indigo hardware and software is going to be compliant to the standard. This includes cameras It seems your facts are several months out of date.

Indigo has always followed standards, of which there are very few in IP video. Now that there is an open standard, they will integrate to any IP encoders that also meet the standard. Look at Milestone, Genetec and DVtel - they are constanlty releasing chargable upgrades to try to keep up with the ever changing formats the different manufactures are putting out. Standards removes this.

Interesting, In the past Sony have not produced thier own IP cameras. They OEM Axis. Anyone know who is making this one?

I certanly have. Great product and has a massive number of quality reference sites. PM Me

IndigoVision has now won another casino on the strip in Vegas. They are also the only IP video product formally approved for casino applications. Around the world 27 casinos consisting of over 8000 cameras have chosen IndigoVision's IP Video solution, reinforcing the company's position as the IP market leader in this demanding industry.
