Geovison system problem, AGAIN!

[CCTVINSTALLER 0]

Few months ago I done an installation (12camera) for a Restaurant using a GV650 (12) card, it crashed yesterday, JUST MY LUCK, and TYPICAL GEOVISION!

 

ATX400W PSU

Intel P4 2.4GHz

MSI 845PE Motherboard (Intel 845 Chipset)

512MB DDR memory (OEM)

MSI MX440 8X Graphics card

Win 2000 professional

- Someone mentioned XP customisation, any method for Win2000??

 

1X Maxtor 40GB HDD (Purely for operating system and Geo program)

2X Hitachi 120GB (Video storage)

1X Lite-on CDRW

 

Any problems above? I’m using both primary and secondary master and slave.

Also HDD Manufacturer? I heard Maxtor got problems and so does Hitachi, I got a few spare Maxtor 120GB HDDs

Motherboard, anybody had any problems with MSI Mboards?

 

The Spec was used for a GV650-16 port (V2) card, of which I used 12 camera ports, most recording on Motion.

 

The system was connected to remote view (broadband) and I used Norton Firewall 2003.

 

When I restart the computer I get an error message:-

 

“Stop:- C0000221 {Bad image checksum}

 

The image wow32.dll is possibly corrupt, the header checksum does not match the computed checksum”

 

I probably have to do the comp from scratch again, I aint going to use Norton firewall, disable sound card, anything else I could do without incurring to many costs?

 

Thanks for the support, I appreciate it

As for the hard drive, all Kalatel DVRs use Maxtor hard drives, have never had one crash on me yet. I imagine they use them because of the large disk sizes they have. Ofcourse a hard drive crash is always possible with any hard drive.

Instead of doing a complete reinstall, try doing a repair install. And reinstall the Geovision software. That dll handles some of the 16 bit compatability stuff.

 

There isn't too much you can do to w2k to speed it up. Increasing the swap file, and limiting the services on startup is about it. Getting rid of Norton is a good idea, get a hardware firewall. And make sure you have SP4, it will help with speed.

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.

If the repair doesn't work right, or misses files, it's generally because you didn't slipstream the service packs on to the disk. SFC can some times do a better job because it will prompt for service packs.

With 3 hard disks working in the PC do you have very good ventilation?

Don't they over heat and cause sunddenly problems with windows?

[Thomas 0]

With heat there are a couple of tricks. One are front mounted fans. Or for the hardcore, water cooling. For the truely overboard, liquid Nitrous cooling. But in all seriousness, you can do alot to help with heat and air flow, but it takes some preplanning. Use rounded or sata cables to help with airflow. Add fans. Add more fans. Get better and more powerful fans.

[CCTVINSTALLER 0]

I never thought cooling was a major issue, the computer case is fairly small, and i had no choice but to mount the hard drives on top of each other due to the space limitations. I'll try putting a few more fans, the computer has a clear side with 1 fan but i dont think that helped much. Cheers Guys

The first step might be a decent case. ThermalTake Xaser III V1000C for example. Comes with 7 (silent) case fans and is perfect for a system running 24/7. It's key lockable too which should prevent people fiddling around.

About £65 here in the UK without PSU and it's worth every penny.

http://www.thermaltake.com/xaserCase/xaser3/xaser3menu.htm. The colours might put you off though.

I just bought a blue one and it's very nice. It's meant I can run the CPU fan at a lower speed - 4300 rpm as opposed to 5700. The fan was so loud before that it sounded like a vacuum cleaner.

The hard drives mount at the bottom of the case directly behind two intake fans which suck cold air directly over them.

Cheers Steve, very nice case, i've seen it at a few exhibitions, i need a lockable case now. Does everyone use specialist cases, or just ordinary cases??. I done an installation for a retail shop using a normal PC case costing aroud £25, someone had switched of the computer and stolen a couple hundred pound out the till. The manager told me to put the password protection so no-one can minimise the program, but that still doesn't prevent someone from switching of the computer. The worst thing, there wasn't even a camera in the office where the surveillance system was

[steve6690 0]

I'm not in the trade unfortunately although I use a home-built GV250-8 at home. I have seen ads for pre-built Pc DVRs in the UK and they seem to use bog-standard beige cases. I'm convinced that my last hard drive - a Seagate Barracuda V- failed due to inadequate heat dissipation. Sometimes it was too hot to touch. No such problems now though. As regards the PC being switched off by a burglar/thief, I suppose there's not a lot you can do about that. Sure, the ThermalTake case prevents access to the on/off and reset switches but they could just pull the power lead from the back. I take your point about not having a camera covering the DVR. I'm no expert, but even I have a camera pointed at the spare bedroom door to record who enters the room as that is where my DVR is. The system e-mails JPG images immediately to my e-mail account via ADSL.

A burglar would have a hard job nicking the PC as the case weighs aroung 20Kg on it's own before you add a PSU.

not really, all they need to do is take the hard drive, which is small and light. the camera itself, or other cameras can be easily defeated by a paint gun. So you see, nothing is 100%. But a camera helps in most situations.

[Thomas 0]

Can't beat the paintball gun, but you can set up a PC to use NAS/or RSync to backup your data, it would take a thief time to figure that out and if they take the drive the best they get is a drive with windows or linux on it.

Talking about CCTV destruction, i actually came across a website dedicated to destroying CCTV camera! Check it out:

 

http://www.rtmark.com/cctv/

[rory 0]

yeah seen that site before, laser was mentioned on another forum, but only works on auto iris lens.

 

this guy that made that site though, has a hate for CCTV only a criminal would have. In other words, if he's not doing anything wrong, or illegal, then he shouldnt be afraid of a camera recording him in public.

 

Either way it is like a site on how to be a criminal, here is one of the funniest parts, I wonder if the guy put this site up as a joke or not:

 

4.3) Learning territory.

Know every part of the area you will operate in.

Explore by day and night.

 

Climb every tree, building.

 

Explore every alley, bush and tunnel.

 

Climb every wall and railing and fence.

 

Don't use paths or streets (only cross them at right angles).

 

If you have a police helicopter in your area then train aerial counter surveillance ie finding exisitng cover, flares, smoke bombs.

rory - they can't physically get inside my case to nick the hard drive. That's part of the appeal of the TT case

[Thomas 0]

One man's protection is another man's police state.

[rory 0]

whats a TT case. I know of DVR/VCR lockboxes, these help, but can still be nicked as you say Nothing will stop a dedicated criminal. Here they come with blow torches just to rob a home now.

 

Edit: ok saw your last post on what it is.

 

Ofcourse an easy approach is to spike the power to a building, killing most electric devices inside, even with line conditioners. But then we dont want to give out too much info on all this, as it may indulge the real criminals.

Steve, case locks are nice, but a good fire axe can open it up, and those locks are pretty simple to pick. A prybar can get the back off, or unscrewing the power supply will give you enough room to reach for the drive on most chassies. Case locks just keep workers from casually trying to liberate the parts from the machine.

[rory 0]

I think it is important for people to realise, that nothing is 100%, and anything can be overcome by the dedicated criminal. Its not a good selling point for your clients, but its good to keep it in mind just incase.

[Thomas 0]

Eh, the criminals already know. And remember a slegdehammer is a useful break in tool, it beats most cases. (Except maybe the HP P3 Vectra cases, suckers could stop a small bullet. Thing weighs a ton, but easy as hell to work in and has enough steel in it to build a car.)

[steve6690 0]

I was just referring to the original scenario in the thread i.e where a shop employee (allegedly) or sneak-in thief turns off the DVR and then helps himself to cash from the till. A determined man with an axe is obviously gonna win the day though, hence my suggested backup of covert cam covering the DVR and instantaneous e-mailing of JPGs. Not ideal obviously but should be enough to catch an employee out.

I recall a client, when I was installing alarms. They had Security Screens, and Bars, and an alarm. Middle of the day the grandmother only was home. Small house. The crooks came as an adult and a child. They pried the bars open with a crow bar or similar. Then they kicked the security screen in, then pushed the child through the space provided to open the door. The alarm went off, the adult went in, rushed and grabbed what they could, then ran out, all the time the grand mother sitting there in disbelief. It only took them a couple minutes, they got away with the TV, VCR, and some jewelry. The police came later on but they were long gone.

 

Another one I remember, theives used a blow torch on a metal door, took them a little while before they got in, when they did, the alarm went off straight away, but they still ran in and grabbed some things.

 

I cant mention others due to the violence (eg, rape) that took place on the home owners.

They can cut the Cable or DSL though, but yes, the average employe wont think to do any of that.

[CCTVINSTALLER 0]

So what other cases do people use to prevent employees switching of the computer?

 

Any other techniques you could use for PC based cctv systems.

 

Lastly any way you could disable the ON/OFF button and Reset button while geovision is running?
