    Question about a Restore CD

    Once again Tom is on the ball, the problem is that if you are building machines and using Ghost as a Pre Install you have to be very wary, next week they may change the driver of chipset for the same Video card you used last time, so then you are not loading the right thing, this is a common flaw in taking shortcuts, especially with Video card Bios and DVr card that can change at a drop of hat! I personnaly like ghost but it should not be used untill a complete burn in is done and only if you are sure that the customer is not going to update a driver or if the hardware manfactorer has not updated his.

    Shuttle PCs for Geovision use

    We dont get it here but from what I am told by my friends it is good Ram, I have not heard a bad thing of it. a common mistake is not to Burn in before installing an OS, you can cook a meal in a kitchen but the waiter has to bring it to you and if he coughs in your soup then its not the cooks fault.. the same goies for the windows OS , it is too late to test after installing the OS because if it is faulty it can copy over currupted info when installing the OS.

    Geovision and the onboard sound card

    Spot on thomas, this also keeps your windows install clean and leaves room for any updates, this way the part of the HDD that has the OS on it is never touched, rmeoving fragmentation and bad sector issues.

    KVM Switches

    I have not really liked the Belkin brand, even though I have one of their wirelss keyboards and mice, I would have to agree with Mick, look for thick high quality cables and you should not go wrong.

    Question on Geovisoin Real time card.

    Not exactly, ifg you capturer at real time and your bandwidth allows then yed this is possible, but you need to capture at this speed first and you need to choose what size the transmitted files will be in resolution, I am not supposed to mention this Yet but Geo are about to release 640x240 or the web so this would mean you would need more bandwidth, you can actually massage the packet size with the Geo sofwtare to increase or decrease the speeds and it will also depend on what compression you use too. I was told by Geovision that you need to capture the frame rate that you want to send, but I actually think their tech was wrong as I thinkt he biffering for transmition actually happens before sofware compression so it is a bit of a grey area at the moment, I will test it eventually but too busy at the moment

    Newbie help please.

    You can buy a RG6 with a quad shielding that will work ok, but copper is always better

    Where to buy power connectors?

    Where are you located.. we get them for roughly .65c AUD

    Need a Back to Front Case for a Project

    Actually, I found several, we managed to tailor it for the customer, I must admit it is a good idea as it makes it easier to find faults.
  9. Ok here is strange one... I have a client that needs some special Rackmounted cases ...But I can not seem to find them anywhere.. This is what I need: 1/ The case needs to be back to front so that the BNC connectors from the cards are actually at the front of the case as well as the CD Drive 2/ There must be an On/Off/Reset switch at the front of the case and front USB as well as Mouse Plugs 3/ The case must be no longer than 41cm and Must be at least 3U.. prefer 4U, it should also accomodate for many HDD's up to at least 5 and must allow for mounting of many fans. Has anyone seen such a beast!!!

    pirate Geovision Card. Who can tell one?

    Actually, USA has the strongest anti piracy laws in the world and have the biggest crime rate in this area, but I do know what Rory means, the newer stock from Geo acxtually has its brand stamped near the PCI pins so look for that, also look for the coloured, dongle rom chip, but the best way to find out is to email Geo or tell me the price you paid for it and I will know if it is legit or not! There is a reward offered from Geo but as if they would pay you for it! What makes you think it is not legit?

    What camera you used for very strong backlight?

    The Ganz, wide dynamic camera is excellent, so is the Sunkwang Day Night camera with this feature (a lot less expensive), what you should look for is a camera with a wide dynamic range and preferably one with onscreen display, with this and programable backlight compensation zones. You can choose to set the area that you wish to use with wide dynamic and it will only affect this area, the reason for doing this is (cant really tell from the photo example) but if you had left it in this mode for the whole area and were looking through a doorway and the subject walks in but accross the street in your filed of view was a white wall then that wall will go far too white, so programing the area really helps.

    Problem with Geo600 card installation

    Because most fast DVR products store an amount in memory before closing the AVI file corruption can happen if something happens to windows causing an abnormal shutdown, some of the newer motherbaoards have a feature that is designed to turn a machine off if undervoltage is found. There are many different types of UPS and 5 different power problems you can have, one of the most common is undervoltage or SAG, some opf the cheaper UPS devices have a feature that will up the voltage to support you when you have under voltage, this is called Boosting up or Bucking up, the others just allow it topass the undervoltage through, the cheaper UPS devices ...even the ones with Buck and Boost, have to change the power in order to do this, this means ..well not exactly... that you rely on the mains power and they do not switch over untill they need to, the problem with this is that it takes a small amount of time for it to switch and this can lead to problems, having a fully functional UPS is unfortunately expensive so Buck and Boost is a good feature but not as good as fully featured UPS with support for all power problems.

    Geovison system problem, AGAIN!

    That problem has nothing to do with Geo There is no mention of the video card that you have used, it is possible that that error is a compatabilty between a later driver of the onboard video and the Motherboard itself, I have heard of this happening when using a later driver for the intel chipset than was originally on the motherboard. P.S. I have seen many problems with using system repair, sometimes it forgets to load certain parts of the O/S, if it is windows 2000 then I would use XP if you plan to re install, maybe the drivers you used to update the intel chip only work with XP? It would also suggest that the actuall motherboard may be having problems, if you qare using a good video card you might find that the later motherboards can not truley turn of the onboard video in the BIOS, we try to buy boards that do not have onboard video for this reason.. Obviously the onboard video is not really supported by the Geovision..although I have seen a NForce chip do hardware overlay. I found the following in the list of fixes in service pack 3 for windows 2000: 299770 BUG: ToolTips for 16-bit OWL Applications May Result in an Access Violation in WOW32.dll I would not USE OEM RAM< this can lead to a BAD windows install and further problems. And I hate nortons as it is such a memory hog! I really have not had any problems with this DLL file as I only use XP but I have heard of someone that did, but they told me it was because they installed adaptec cd creator and turned off the auto run feature of the CDRW.. but I did not believe them.... Good luck.. My advice is try service packs first then install with XP if all else fails and make sure you have the right video card for the job..... Once again another example of how Geo gets the blame when it has nothing to do with Geo.

    What is more popular in your area?

    Hay guys, I really know that I control a lot of these posts with my Strong opinions, but really I want to keep this one simple, so please just put where your from and what the market is doing, not what you think model wise is best.. thats what the DVR section is for.... I have also just put up a post there on a standalone I want to try, I would appreciate any feedback on it.

    GV-250 oscillates, triggers motion detection

    Because a PC card works with a multiplexing chip it is important to choose the inputs carfeully if mixing colour with B/W, for instance a 16ch card may mux channels 1, 5, 9, 13 so putting your B/W cams on those ports prevents overshooting, ther is also a difference between analogue voltage and Digital recieving.. the best video signal is recieved at 1volt peak to peak but DVr cards tend to prefer 1.1 volt peak to peak, most good cams do this anyway but cheaper cameras can be a problem as they can be short on the required settings. It is more likely that you have a ground loop or have failed to load direct X 9 before intstallation of the software for your card, this results in picture bouncing (marginally) which can result in the representation of actual motion events that do not occur, you can adjust your system for the gain differencial in the software if supported or switch the gain control setting on your camera to AGC (auto gain control).. i would bet it is more likely a ground loop but under voltaged cameras can have issues aswell and this tends to happen when too many cameras are on one power supply or the power is not filtered cleanly or regulated. I hope this helps GC

    Geovisoin and Pelco PTZ cameras

    Yes they support the P and D protocol
  18. The Obvious short comings with a standalone are the following: 1/ A lack of features not to mention the lack of ability to be easily upgraded, features are the key to future devleopments, I mean isn't a VCR a standalone? Computers give room for more improvements than a Standlone does. 2/ Stability... One floor that exists with a standalone is that it uses the same parts as a PC does (most of them) therefore it is just as prone to fualts, the only true difference is in the operating system itself, for example if the VGA chip dies on a PC machine it is easily changed on site in a few minutes sometimes..even by the end user themselves, but if this happens on a standalone, a whole replacement of the DVR must be ordered and this means you have to keep stock of them which is much more expensive than a few video cards. 3/ You have mentioned that there is little difference well I disagree... your kalatel unit is the same one you bought from day one, the PCI card I bought at the same time has seen over 20 changes to it and they were free and at no cost to me, I can also much more easily customise the system to my needs, software on PCI cards is much better than a standalone in many ways,...The kalatel unit lets you email thats nice but not very impressive.. it has not been designed to send the video to a control room as a stream, dump a data base, co interlace with POS and text you as well as buffer to another DVR.. Standlones can not share network bandwidth as well, you can aadjust this on a PCI card, you can even throttle it, there is no two way audio on the Kalatel and you must run software to remotely view the log files and if you back up on media then you are required to use the encoded softwrae to play back what you have recorded. If too many users connect to a standalone it will suffer for the small Ram it has in it, you can avaoid this by using multiple machines on the one network to share the workload or you could add more ram. PC systems can be configured over several operating systems and many file formats, but most importantly the big issue for a Standalone is price versus speed, because there is not true CPU integration and no room to move, most standalone machines rarely capture over 50FPS and these are expensive as hell. You mentioned that there werent many features that you would use but I can think of many... Personalising the password entry system for one, Object tracking for another, buffuring the video off site, listening in to mulitple channels of audio, replacing the desktop, Object counting, licence plate recognition, and the ability to buffer frames for recording on the fly and not a at a predisgned value. how about PTZ Motion tracking or Database recording of whom has loged into and out of your system, Computer based time syncronisation, the abilty of firewall integration, AVI repair utilities or multichannel Audio recording, what about a corporate job where mapping and twin screen display could be used, unlumited I/O relays, integration for safe shutdown through the use of a UPS device, multiple level digital zoom, de interlace rendering, control room software for free.. you pay for the enterprise gear from kalatel and its the same thing. or what about the COST the 50 FPS Geo is a thing of the past I can buy maybe 8 100FPS cards for the price of one standalone. 4/ Reliabilty is not myth but way over exagerated, the truth is that you cant just waltz in and get the bits to make a Kalatel but you can to make a PC and when anyone can do it then it is up to the ability of the engineer in making these devices, I mean kalatel (well actually whichever company they source from) would have studied the hardware for compatability but with a PC anyone can use any part, but if you were to compare the prices you would find that paying the same amount for QUALITY computer components would make a very very stable system. Lets face it Linux is more stable than Windows but arent you running that on the same hardware so what is the difference between the ram in your Kalatel and the Ram I use, both can fail but let me tell you the ram in the Kalatel that I saw was OEM ram and I bet that raises a few eyebrows to anyone here that knows computers, it does not matter what OS it uses if you use bad ram.. I mean if Linux is so darn stable why does no one use it much.. because its a pain to use!!!!! and is hard to update!!!! Drivers are harder to write for!!!! so go figure!! tell em is an XBOX a standlone or a PC, you see it can be upgraded but is it really a PC, its an embedded OS, but whom has not seen one crash???? You can put Linux on an XBOX and use it as a firewall.. actually a very cheap way to do it, but will it play Half Life 2 when it comes out NO... because it isnt as easy to upgrade as a PC so when the latest and greatest comes out it will be on PC because THAT is where the money is spent on development.. not really in Standalones... with a Standalone you are stuck with what you got, there is no updating hardware without expense and this is why PC Gaming is much more popular.. do you know what drives Intel and others to make new hardware that we can use for DVR's... GAMES.. yep thats right.. End Users on PC's they are what drive the development of new ways to display and capture, do you know what drives the development of CCTV networking.... PC USERS NEEDS FOR INTERNET!! and once againt he future of all CCTV will be driven from WIFI and this will be strongly contributed by PC users needs again! The Kalatel is a PC so is the XBOX and yes some are more stable than others but if built well the MYTH is put to bed! I admit that XP has its issues but not by anywhere near the amount you state, granted though it is more suscepatble to attack but thats like expecting terrorism in NewZealand compared to the US!! There is more users so it is easier to attack, more of a target because it stands out and more scrutinized than anyone else. A WELL built PC can OUTPERFORM, any hybrid miniture PC embedded or not and is easier to use, with more functionality, I agree there is less headaches with a standalone but the limitations versus stabilty is not something I have seen and the MYTH is too strong. I just ugraded to version 6.1 of Geovision and you have probably only changed your sofware twice. Yes there will always be badly built machines in the market and yes this will lead toa bad name, but as I have said before, people pay me because they know I know my stuff, they cant make much of a choice if someone sells your product to them.. its the same no matter who you get it off. One thing I will say though is because the standalone is so limited it has the abilty to limit support which is a massive plus and yes if you only do small jobs then you may never need it but who wants to stay doing small jobs?

    Building a Geovision system

    Personally I would not do it but in theory it should work as long as they do not steal the IRQ's from each other, I would uninstall it from the device manager and leave it uninstalled... hard to do with XP unles you know what your doing, removing the INI files ought to do the trick for you though. It would be more practical to taqke one out while testing the other

    opinion on Computer to Run Geovision GV800-16

    That should be fine for a Geo System, MP3's should be ok, but personaly a DVR should be on its own
  22. cctv_down_under

    Geovision D - Type

    The D type connector is on Version 2 and three cards, once you go over 4CH in size you can use them, they are a VGA type connector with Flyleads, I think they cal that a DB10 connector but I am not sure, it allows you to only take up one slot on the back of your DVR, this means more room for additional PCI devices
  23. PM me the prices you got from Geo.. i can probably do better for you.

    I do not know a lot about it actually, I meant to say PCI 8X (8 Times)... I guess thats why we employ technicians
