  1. I lost my iphone between filling up & the job yesterday, and I'm thinking of going with the Motola Atrix to replace it. The iphone was trashed after being skied with for >2 seasons & didn't even ring through reliably so I was shopping before the mishap. I'm thinking of just getting a home & car dock, not the "notebook" dock, maybe later, maybe not. Anybody else heard anything about this phone? It looks like it took the consumer's best award @ CES, for all categories, so I'm thinking it must be good. If only I could buy another Samsung SPH-I500 (my fav phone of all time), I'm not sure I need a gigantic screen in my pocket. http://reviews.cnet.com/motorola-atrix-review/#reviewPage1 sph-i500
  2. trying to figure it out. coming from an iphone. The fingerprint scanner is pretty easy, texting is nice, size seems about the same. I was out in the field all day though, same thing tomorrow. I'm having trouble setting up Google Voice (visual voicemail) - well, trouble setting up my greeting anyway.
  3. Yes & no. We have the right under the 'fair use recording act' to record a copy but not distribute it, but we have to circumvent a law or two to do that. I think the issue is with DRM, but MY issue is getting the DVDs off of my shelf & into a box. HDs are just so cheap, & I'd rather have books on the shelves (I'm a huge collector - errrr, buyer). Silly, I know, it looks like the books will join the DVDs in the basement within a few more years.
  4. DVD Decrypter was less than good. Any free programs?

    Outdoor surveillance - help neded

    Tom, what's the monthly fee & model # for this GSM device?
  6. I'd think a wearable mic would be the only way to get quality audio. Something like this: http://www.amazon.com/Olympus-WS-400-Digital-Recorder-White/dp/B00264TQQM/ref=dp_ob_title_ce?tag=gpse-20 This one in a shirt pocket would work, but simulate the situation - clothes rustling, wind blowing, etc. Prolly do better with an external mic.
  7. Don't forget to say "heyyyyyyyyyy"

    University Project

    he's a great author on the subject. I wish I still had a copy of this: http://www.amazon.com/CCTV-Surveillance-Practices-Technology-Newnes/dp/0750698365?tag=gpse-20

    Post processing video for motion

    this may be a little off topic but could be helpful at least as a bump to your question. Sometimes I'll split an analog camera @ the back of a DVR - one lead goes to continuous record, the other is set to motion only. Since the video signal is weaker I'll go in & tweak the contrast, brightness, & color settings to get them back to normal. I've done this for Safe & back door contacts several times.

    New Wired Design, What cable/cameras

    RG59: just over 800' (maybe 830') RG6: 1200', give or take I don't recall which book I read this in.
  11. sorry - Terminator On if it's the only or last device connected. My brain hurts too - but that's another story
  12. in Win7, not sure if it works in vista, turn off User Account Control and Action Center. EOM.

    How to capture screenshots from VGA output?

    Print screen excludes live action (on my system), I haven't tried snag-it yet. I pulled the skin file off of an old machine to work with earlier today.

    WiFi router with PoE?

    OT: I'm a fan of individually-fused power supplies. POE seems like a bad idea to me since one short could cut out all of the cameras.

    Display issue..

    the little yellow exclamation point should've clued you into the problem. Congratulations, you're now ready for Windows Update.
  16. I have one of them running in the field - I noticed no difference between it & the 32 bit version, but I haven't had much time to play with it - if it speeds up smart search (filters on the fly) I just may switch.. Time to test the next one. Apparently the 64 bit support came just in time, I bought 2 system builder copies of Win7 64 by mistake. This co is actually fairly responsive, they added a time stamp on playback @ my request 3-4 months ago.
  17. Something like this may be ideal: http://www.cabletronix.com/support/manuals/CTARM-4IR.pdf

    Angry about lenses datasheets.

    do you have charts similar to the ones in your link? The only ones I have are on pages or backs of books, I'd like to find some larger charts to experiment with a little. It looks like their ir lenses are actually cheaper than some of the others. Tamron isn't giving these things away. 13VG308ASIR-SQ 13VM2811ASIR Let us know how these turn out, and if you think there's no reason to use them as a go-to box cam lens. I wouldn't mind switching if they're good in a wide range of situations.
  19. I sent you a link to my website, is that not good enough? Would you like me to quote some prices from DWG's site? They took a stool sample before they'd create my account. Here, I think I have some left:
  20. OT: Soundy, pull out your $10 harbor freight meter next time & see where the shield is connected to next time, chances are, it's not. EOM - I'm out. Have a great day guys.
  21. OT: Problems that I've ran into with distributed audio in this scenerio, which also deals with what we thought were ground loops were say an audio amp / sat receiver on one end of the building, & the phone switch at the other. Some of the mics we still deal with are grounded at the amp, the ground *is* terminated @ the mic, but it's only the cable that's grounded when checked with my meter (hot/ground/common -or- rd/bk/shld). These mics are also they type that are commonly connected w/ XLR connections, not that it matters. We also deal with POS & OCS systems - they're spec'd to have iso grounds to prevent variable ground potential issues on the network & between devices. The best illustration of the problem (variable ground potential) had a bunch of boats on a bunch of different waves, each boat was floating on a wave at a different height. This illustration was supposed to show the relative difference between the relation to ground on each circuit. A quick google search turns up nothing that I can help others see what I saw, but I'll post it if I come across it. Early on (about halfway through my CCTV career about 9 years ago) I had issues with great pictures, but every so often, like every 30 seconds, a camera image would flicker. It took a while but we went with regulated power supplies. Over time, maybe just out of luck, I gradually switched over to individually fused power supplies. It works for me, it's cleaner, & it's a hell of a lot easier to help the customer cycle the power to see if it'll help a blacked out camera come back up before we send a tech. I've also had issues with dealing with grounding issues, over cat5e, throughout an IR system on a hospital's IR repeater system that we put in for their ERs. There was severe EMI that was fixed on this somewhat large IR system by grounding the unused cat5e (approx 4) wires to either the chassis or earth ground (conduit) - I don't recall, that was >9 years ago. So I've tried every conceiveable method on several different technologies, & sometimes it boils down to what would appear to be some sort of workable electrical principle dealing with EMI on the lines on STP & UTP, in Audio, Video, & Data lines. Take it FWIW. Or don't. I have more technologies where this works, weekly, but the bat signal is in the sky and I has ta go. I suppose the only thing you absolutely should gather from my OT post is that grounding the cable @ one end is good, umkay - grounding both ends is often problematic. I haven't worked with baluns in this field yet, and I have absolutely no experience with IP cameras, so I'm afraid this is all I have to contribute on this topic.
  22. It sends the EMI on the cable to ground, I thought. Grounding both ends can cause radio stations to be picked up on line level audio signals IME. oops on the analog, I missed the thread's title.
  23. Like what? Are both ends of the cable grounded in your scenario? Can you name a single instance where it would be a better idea (using analog cameras in a single building with under 800' runs) to have random transformers plugged into random outlets powering random cameras?
  24. Leave the FG, or floating ground terminal unused. You should be fine with your 18/2 siamese cable. The poster who's recommending the central grounding is basing the recommendation on keeping the ground potential the same throughout the system, & it's good advice in both my field experience & understanding of the theory. Having a central power supply (fused box preferably @ head end) seems to fix any ground potential / loop issues.
