Insufficient money spent on system - what to upgrade? :)

Post here to ask any questions about hardware suitability, configuration in ZoneMinder, or experiences. If you just want to know if something works with ZoneMinder or not, please check the Hardware Compatibility sections in the forum, and the Wiki first. Also search this topic as well.

Insufficient money spent on system - what to upgrade? :)

Post by JimS »

I have been doing a fair amount of reading prior to setting up a ZM system but still have lots of questions. I am also just learning Linux but have a fair amount of PC/electronics experience...

Want to set up ZM, eventually with Misterhouse and a few other things so I want a bit of margin. I stuck with what I considered decent, modest stuff as it seemed sufficient and for SAF. Now I am hearing it needs to be easy to use and not to cut corners. Translation: I should spend more money. :)

Background: We used a VCR to record some by the hour work with large equipment and found they were generous with their time tracking - about $500 worth on a $8000 job. When we pointed out they didn't really have that much time in they didn't argue much and just reduced the bill. We have an even bigger job in the works so...

I plan to have up to 5 cameras, probably 2 to start. Here's the current hardware plan:

1 GHz PIII with 512 M of RAM, 40 G HD (already have)
Capture card: PV-143 (from Bluecherry)
Cameras: TP-6360WBC-DN (or possibly the TPH6360...)
These will be outdoors in the midwest so issues are temperature extremes (but protected from direct rain) and decent low light performance.

Some of the other issues is no sound but I can probably just use another program to record 1 channel (was useful to hear when the big equipment was running). Playback of the recorded stream of frames needs to be user friendly as I may not be doing it. Also some concern about the size of the HD although the framerate could be fairly low when no motion is detected. Could drop an additional 80G HD in for video storage.

I considered hardware encoding/decoding but encoding doesn't seem that common on low end cards and decoding is less of an issue. As long as I keep frame rates at 5 FPS or less I think not having it will be ok. May do a realtime DVR (freevo?) some day but that will most likely be different hardware anyway. Briefly looked at Matrox G200/G400 but the units didn't appear to have inputs - seemed to be mostly for playback.

Would like to know what others would recommend modest upgrades on. After the major work is done it will be used for general home security and automation.

That system is light. I have a 1.7ghz celeron with 1 gig, amd a single chip 4 port card. The system can struggle when streaming. And at that hard drive, you are looking at a day or two tops. An old adage I go by is that there is nothing more expensive than a cheap fix. A used 2ghz system with a gig of ram can be had for $150 and a 500 gig HD goes for $75, so why not do it right the first time?

what to upgrade?

Post by JimS »

Thanks Lee,

Thats exactly the sort of feedback I am looking for. I agree that a cheap fix can be expensive - and frustrating...

When you say your system stuggles when streaming... What exactly do you mean by streaming? Sorry if this should be obvious - I am a complete newbie to this. Is this when the system is capturing and also displaying recorded video? What frame rates?

What else is running on the system? My understanding is the GUI takes a fair amount of resources and some are lighter than others. If you are viewing on the same machine then some it would be required. Not sure if it is required if you aren't viewing.

When you point a web browser at it and look at the pictures. :D If you run the web browser on the ZM system itself, it gets very bad, but still it is a hit from other systems. Just not enough headroom for me... Also, the faster frame rate means more pictures buffered in memory, which you will have none of, and that means swap. Now you are talking a world of hurt. The system you have might cut it with a gig of ram and a larger HD. But it might be at 2 fps per cam.

that setup is very close to mine (i have dual PIII x700)
FPS is 1.5/1.7 running 4 CCD cams @ 640x480 load 1.3/3.4
does what i need but i think you might need more than the 1GB ram and most certain a larger HDD.

PS also keep in mind the PSU for your Computer, upgrade to a good High output as the PCI bus and HDD are going to be working overtime.

Upgrades?

Post by JimS »

Thanks for the feedback! Seems I will be looking for a better PC. Might use the current one just for learning the system until I figure out the best hardware...

Lee, I'd like to know where you get a 500MB HD for $75. :) Best I have seen is about twice that price. The used 2 GHz PC with 1GB of RAM price seems a bit agressive too although I might be able to do it with some effort.

They are a local wholesaler as well, and I do get a reseller discount. Unfortunately, the drive I purchased last (which listed for $85) seems gone now. But $106 is still cheaper than $150. :)

500 GB drives

You can now get a 500 GB drive for $90-$100. Just check dealnews.com. Newegg.com recently had a sale for $90 for the aforementioned drive along with an external, aluminum case.
