I know heaps about most of the DVR cards so if you need any assistance please do not hesitate to call.. If you would like to try our demo email me and I will send you instructions on how to log onto ours and speak through it! digitalsecurity@westnet.com.au

Ok now we are getting somewhere, DHCP has nothing to do with the name that is DNS Domain Name Serving. DHCP allows your I/P to refresh all the time with a new one.. 1/ I do not know this sure safe product at all is it PC Based or Standalone? Set your DVR to subnet 255.255.255.0 and I/P 192.168.0.3 (Fixed) Set your PC to Subnet 255.255.255.0 and I/P 192.168.0.2 (Fixed) Then you should be able to ping the DVR from your Computer and all should work fine. If you can not Fix the I/P of the standalone and it uses DHCP only then 2/ Turn on internet connection sharing on your PC this will enable your PC to be a DHCP server and it will issue an address to both your PC and your Standalone, problem is that you will not always know what it is! The problem you have is that you have DHCP turned on and you have nothing to serve the machines with an I/P, its like this... if you fix it ..it knows where it lives but if you want it to fetch one it has to know where to get it from and you do not have a DHCP issuing server so it looks but cant refresh the I/P. You need to turn on internet connection sharing and make your PC a DHCP server if you want to use DHCP. OR 3/ Buy a router and set it to issue DHCP to all your machines, also tell it to only use a range of say 3 I/P adresses for instance 192.168.0.2, 192.168.0.3 and 192.168.0.4 then you have only three possible I/P's that it can use so you will always no it is at least one of the three. Lastly I think what your trying to do is connect to an outside I/P range, for example 10.1.1.3 or 192.168.0.2 are internal addreses and work only on a lan, if you try to connect to 202.168.45.12 then you are trying to connect to something through the internet so if you were to type that into your browser it will head in the direction of your cable modem and internet rateher than on your lan... look simply buy a router and if you can afford it get a static I/P.. also you could use a Dynamic I/P mapping program if you needed it.

Nice pics Are they all non PC products, what PCI card machines have you done?

Exactly... poor old wiondows gets a bad wrap and is blamed for everything when you can make it much more stable indeed! Mind you Linux is great but so hard to program!

I am not really sure if this is your problem but DHCP is the automatic distribution of I/P adresses, There are two things to take into consideration in regards to this matter. 1/ If you want to connect to your system via I/P from another off site location then you will need to know the I/P address of the system, however unless you pay for a Static I/P then your I/P address will change everytime your machine connects to the internet or even while you are connected. If you fix your I/P address to a local addres on your internal network then you should be able to connect to it through your local LAN network. In your case it would seem you have two machines connected on the one lan, which one is serving the I/P adresses if you are using DHCP? Also are you sure you are not using a Router which would require port forwarding to be able to connect to the box in question. Give me some more info and I wills ee what i can come up with. 2/ Try setting your subnet to 255.255.255.* and make your PC 192.168.0.2 and make the DVR 192.168.0.3 and then try to ping 192.168.0.3 and see if it bounces back to your PC When you ping it as Fixed I/P can the other machine get a response!

I was not talking about a custom version of version of windows, I was just mentioning that there are a lot of tweaks that you can do and a lot of parts of windows that are not necessary to load up. Especially windows XP, some simple things as well can be removed, for instance, screensavers affect the DVr, Ram speed latency, Bus speeds, Pop Ups. windows Update etc, Slowing down the GUI etc etc A lot of companies buy a PC then slot in a card and unless you use the right rated equpment and make driver adjustments then you can have issues with your system.. All In all though Linux is much more stable, but is so woefull in features that it is a trade off!

I have never used these boards before, howevert here are actually very few different types of cards available to the market and most of the companies that sell them just make their own softwrae development kits. Thes look a lot like Comart Systems cards, they are most likely from Korea and they may have any software on them what so ever

I had no idea,, my apologies to everyone,,, however... does that not mean that to view the encoding of site the police or owner would have to have an encoder player at home? that doubles the expense and that I imagine would be a haslle for police as they would take your whole system would they not. Mux is slow, encoded, does not usually encorporate , masking, searching, paging, TCP/IP or Audio... I was simply stating that for 200$ US you can get the same thing with all those options and it can record uncoded! it would surely cost more to have 2x components tha 1x component!

Wow there are some good points in here. 1/Firstly, I meant to say buy Seagate or Maxtor they will fail less, try to buy 7200 Spin hard drives too but never mount right next to each other, you can purchase extender brackets to mount extra drives. 2/ Purchase drive cooler bays and if you are mounting this many drives of that size you should be usuing a bigger power supply for the computer, try to use rackmounts for the airflow and if there is an extra mount for a fan in your case then use it, especially exhuast fans, you can put small heatsinks on the connexant chips but be carefull. 3/ The GV600, GV900 (200Fps) and GV1000 have gain control settings for each camera and that should fix your noise problem, power spikes and light changes can also affect motioned recording and use of a line filter is great option. 4/ Relays through the optional I/O board will alow you to use sensors to detect movement and this is much more accurate. 5/ Only use intel chipsets and make sure your video card supports hardware overlay or you will not be able to go to full screen. Geovision will release motion pop up next week, making each camera go to full screen when it detects movement, they will also relaease POS interface and Object counters as well as thumbnail indexed searching and the Web option will be new as well, they also released their own codec and I would suggest you warn your customer not to upgrade untill you check compatability. 6/ Geo uses post and pre event recording which stays in memory, therefore if the power goes out and no UPS is there it will not close its AVI file and therefore you have corruption on the second drive (never record to the default path) this leads to the index getting confused, there are many ways to fix the probem, 1/ Software UPS 2/ Use thumbnail view (only works in XP) in the video storage folder and view each folder as individual dates and in thumbnail view, if dates are out of order or seem weird, then there probably will be corruption in the folder, also if when you change to thumbnail view it does not preview on each folder what is inside each date (pictures) then it probably has corruption and if it wont play in windows media player when you try to open the suspected corrupted file then you need to get rid of it. 3/ Run the repair database utility always after any removal of video files. I told Geo of their issue and they wrote a repair AVI utility but I have not tested it yet OHHH and yes this happens to all products on the market except linux based dvr's Lastly, you do not need to buy branded cameras to get good performance, half of them are re-badged anyhow! PS bet you like the Ganz gear.. Oh yeh and never use a bullet to view a door unless from an angle as most bullets do not have auto iris and not many are wide dynamic so your customers face might look black and shadowed if bright light is behind them.

I dont think I am wrong (however not really used much in the way of mux)... But I did not say that a mux does not record full frame images, I only stated that once it comes out of the mux on one cable to a 1 input DVR then you can no longer utilise the encoded images? Maybe you can but I have nevr seen that, Mux's are very slow and as they are still anologue, they lack a lot of features that you mentioned, howeverI have seen Digital Muxs.... but why bother when DVR is as affordable or standalone embedded DVR @ $200US .Can you clarify for me how you can get 4ch into a sigle ch input without switching or making images smaller as I was not aware this is possible?

-------------------------------------------------------------------------------- Originally posted by xtreme: I'm just curious about why there is such a shortage of Linux based solutions? As a consultant and a Systems Administrator I work with Windows systems day in and day out. Windows systems have issues that seem to be very un-desirous in a security environment. I recognize that many systems based on Windows are very accessible and user friendly, but those same features create a headache for those of us in the back office. I found a few Linux based cards from various companies that seem to do it all, but they do not record audio, the one feature that I require. So I would agree with you that the Linux platform lacks the full feature set that is easily found in a Windows solution, but why is that? Somebody could make a small company work well with such a product because many of us IT guys are so anti Microsoft that we look and look for something that is not Windows based. I’m not so far out there that I “hateâ€

No problems, I would be happy to give you guys our site, but as this site seems to be sponsered by PELCO, I do not wish to divulge our company info, in australia we are quite technically advanced and I am one of a few people that have bothered to do some research on DVR cards but Australian Business is all about the greasing of palms and not about knowledge. I mean government buys from people who distribute these " So called" high end products and tenders are written specifically to a manufactorers specifictaion... I will have a think about it but I would be happy to give you our Korean manufactorers details or our Japanese manufactorer but I would be wary of posting it on here, as I see this as a potentialy big thing that has just started and I would not risk our competition knowing our sources. Mind you I did try to offer my assistance to the big companies however they were not interested... which is great now because I slowly eat up all their business.. let me give you one word of advice....Most manufactorers sell direct and NO you dont need to buy lots to import.. so you are buying from a distributor then a dealer then you have to mark it up... you arent even the middle man!!! CCTV in Asia is soooooo cheap, you can get anything at one or two peices,, there is no loyalty... I sit back and watch the big companies with all their overheads mark it up then just sit in beneath them and make a killing!! As you know price is everything... but yes so is quality but keep in mind companies like Kalatel have overheads but most companies arent manufatoring so that means that they are buying form Asia and re-badging the gear.. why buy from a middle man and then have to quote against them!!

I dont think you undertood me.. to record a multiplexed image you record one frame of small squares and if you have one input into a 1 ch dvr then you are recording a multiplexed image... meaning that each camera is recorded in one large picture... very small when 16 cameras are done! Digital MUX and standalone are the same thing!!!! and to be honest those prices are way out... you can buy 100fps 4 Input imported for $200US and if your stamps add up to more than $1400 US to ship a $200 item there is something wrong. Plus recording from the mux will probably be slower than the 100fps dived by four 25FPS per channel that you get with a standalone unit with no operating system and alarm inputs... so why would you get a mux at all when the standalone is a mux!! The prices I have seen in here are insane and I can only assume that you all are trying to disguise actual costs... the kalatel single channel recorder is nothing more than a connexant based chip on a proprietry board with a MUX chip and looping output balanced 75 OHM signal... why should it cost so much??

Posted: Fri Nov 14, 2003 5:57 am Post subject: -------------------------------------------------------------------------------- Actually Terry Ainsworth from Kodicom Australia is already importing several items into the U.S. along with the Kodicom boards. He is doing quite well from what I've heard so you might want to look into doing something similar. rory Posted: Fri Nov 14, 2003 3:00 am Post subject: -------------------------------------------------------------------------------- quote: Yes but Terry operates of about 150% margin and the gear is not as good as what I already import!

How can a Mux and a 1 ch standalone be less expensive than a 4 or 16 ch standalone? I mean the most you would pay would be around $1750 for realtime 16ch standalone with multiple drives But you can adjust the frame rate of the standalone anyway! and compression! and file size!! and bandwidth!! -------------------------------------------------------------------------------- having an input for each camera is a must for good qulity recording. -------------------------------------------------------------------------------- I did not make this point well, you can get good quality images, what I meant was to record more than 1ch onto a 1ch machine like you were proposing would mean either switching (loss) or MUX and the images may be so small they can not be indentified easilly, four small squares to vs the size of one full picture is a big difference I agree that Digital is much better I never sell anything else I meant why use analogue components like a MUX and switcher before you reach the digital recorder

[ Cmon thats still pricey, I was trying to be conservative I mean I sell a 4ch 100fps Standalone that records at full PAL resolution and has inputs and outputs plus twin VCR output.... @ $670 Australian $480US and that is fitted with a 80GB HDD and I am expensive!!!

I cant beleive yopu guys pay that much for your gear!! That is crazy!!!! I could drop ship it to you at that price,,, wow talk about expensive!!

How much would you like to pay? I can get some to you cheaply if you want to buy bulk?

How much would you like to pay?

Thats correct dont use it for anything other than television arial!

All those instances had good lighting, there are many cameras on the market offering a switch mode to either second sensor or black and white imaging on low light levels, however I prefer the wide dynamic digital cameras as they will allow you to take light from areas of light in the picture and enhace it to other areas without light.... For example a glass table top bar with fluro lights built into it in a bar that has ambient (low lighting) will result ina wash out of light in the area of the bar and no real identification, to fix this with a wide dynamic range camer you mask out the light of the bar and transfer it to the darker areas, works great to get faces as people walk in dorrs with sun at their backs,, not cheap though around $600 Australian Retail which I think is about $400 US, you must make sure you have a suitable F Stop lens though

You can get text overlay boxes cheap howver Geovision and many others include it in the latest software release they have at no cost! Howver some Text overlay box's allow for triggered motion, like a faster recording on "No Sale" Transactions, text overlay should be cheap as it is very simple, the things to look for are systems that allow to move the text on the screen to where you want it or have transparent text, also some allow for dumping a log of transactions to the PC for reference but check that the text box you buy allows for the protocol that your register uses.

Some Tips. Geo has motion sensitivity settings and that may help reduce your noise problem, not using correctly shielded or good grade copper can also produce noise. I have done over 272 Geo systems so far, they are an awesome system so if you have any questions I can sure help you out!

I am going to add fans to the harddrives. Lack of proper ventilation was probably the reason behind the HD failure. The fans are only about 15 bucks each and they don't draw much current. Stear away from Western Digital or IBM drives, seagate or maxtor and never mount them next to each other, buy the brackets to extend the IDE bays and use cooling bays with LED lights to detect temperatures. You can use rackmounts as they keep the air flow going and keep the conexant chipsets cool especially if you are to mount a Real Time Card Next to them. A UPS will solve 95% of all DVR problems if it can be a software ups.. as because the buffering of files into memories is not closed on blackout or sag in power, it leaves corrupted video files in the HDD which should also be partitioned so as not to strangle the swap file, corrupt files = reboots and problems.

Firstly, how do you include the previous message text? Secondly if you are only getting the stated recording times what compression are you using, you must not be using MPEG4, you must be using JPEG to be blown out that far unless you are recording a full resolution standard!

Whatever advantages a PC board system has, the biggest drawback is that it is a PC and we all know how reliable windows is! ) PC Based systems are never as reliable as non pc based systems, howver it is a myth that they are unreliable, the problem is that most people selling DVR boards have no idea about compatability issues with north bridge chipsets and the hint bridge of the capture card and therfore windows gets blamed and PC based systems get a bad name, you can shell out windows to make it run much more smoothly, to be honest a lot of comapanies push the angle of plug and play standalone because the proffit margin is so large because they are cheap to manufacture. You can get cheap PC units that will be much better than any standalone product but yes, operating systems if not set up correctly can cause problems and windows does have some issues, howver 90% of the bad image PC platforms have are from people who do not know how to use them!
