I like newegg.com.

Some of the IP cameras do multimegapixels. The IQeye cameras are great but extremely pricey.

If the guy is sharp, then his best bet is to try to get you to prove a negitive. He'll try to make you prove it was impossible for the video to ever have been tampered with. (BTW, this isn't a digital problem, the same trick was used for years with tape) You can't prove it beyond a shadow of a doubt, because you weren't there with the CD at every step. This isn't a video evidence problem, it's a problem with any kind of evidence when it's the primary source. And keep in mind, he doesn't have to disprove the girls did it, he just needs to prove that there is a reasonable doubt they didn't do it.

Techs from SBC lie. Like dogs. The line testers they use are like line testers for coax. They look for faults in the line from the home phone to the junction box. Those lines fail about as often as coax, so unless you have a major rat problem, or like to hang paintings by the outlets...the cable probley didn't fail. RT is the remote terminal. It's like a bank of modems with incomming fiber connections rather then phone lines. It's handling the PPPOE portion of the transaction and acts as a gateway to the SBC/Verizon/ATT networks.

The ISP line test is a joke. All it does is shoot the line to the backbone provider. So it's a test to see if the ISP is connected. ISPs can't do a trace on a physical DSL line. I went through a week of trying to point out that my modem was getting an IP outside of SBC's range and they insisted that they were "shooting" the line. Well the card at the RT died. And getting to those people was a farking pain with SBC.

Yep, cause those six LED's are going to put out a huge distance. But got to love the evening news and the scare tactics.

Honestly, if the guy is that good then he's going to latch onto the fact you can't be 100% certain that the video hasn't been tampered with. He's going to ask about watermarking, and if he is smart then he's going to ask how you know the watermark itself hasn't been tampered with.

I have had contact with them but they do not use our products.

Corp/Goverment Keys don't require activation. Is probley why Rory has never done it.

Are they still rebadging Milestone?

A bit of a long shot but try turning off hardware acceleration.

And if you're in FL and using Dial up or DSL I would scratch the keylogger for the same reason as phone recorder. I wouldn't do anything that touches a telecomm network. Honestly I would just record video.

There is a reason we require wire transfers for international customers.

I've never liked the less wiring arguement. Unless you had the foresight to prewire rather high up on the wall, then you're going to have to pull some cable. And if you have to pull cable anyway......

Just as a note, using a tape recorder under those circumstances is going to break the Federal Wiretapping laws. Since neither party is giving consent you are going to break the one party consent test. And before someone pops up with the "well it's my home/business/whatever" please keep in mind that the law doesn't care about that. So why does it matter? Because the moment you confront her/him/it with this kind of evidence you're opening up a large hole in your own divorce. And god help you if you are dumb enough to introduce it as evidence. Since that would be admitting to an officer of the court that you violated a federal law. When it comes down to it, that becomes a hell of a hammer when it comes time to discuss post marriage payment.

Sorry, I tend to use DVR and NVR interchangably.

And that is why an IP based security system needs to be on a seperate network. They should also be on seperate hardware. Differant switches, differant wiring and the only common point between the two networks should be the DVR.

From the techincal side there are alot of ways to handle watermarking, all with upsides and downsides. It is in theory possible to replicate a file with the same watermark but differant video. But in theory I could win the lotto, get hit by a bus, get married to and divorce two supermodels and have a space station drop on my head in the same day. The odds of editing a file, getting something that "looks" right and matches the watermarking....is about as slim. And the guy who does it for you is a DaVinci caliber genius.

Compression would lower the number. And the numbers I got from an SDK.

740 x 480 x 6 (Pixels x RGBvalue+location value) = 2131200 bits. Note we're in bits still. 2131200/8 = 266400 Bytes (8 bits is one byte in PCs. Keep in mind this is an arbitary number) 266400/1024 = 260.15624 KB (Bytes to Kilobytes) 260.15624/1024 = .2540588 (KB to MB, guys note I'm rounding here but not in the calulator. We now have the value of one frame, both fields.) .2540588 * 30 = 7.621765 (Frame size * the number of bytes per frame) 7.621765 * 16 = 121.94824 (Frame size at 30 fps * the number of cameras.) Allow for 5 mb/s overhead....and 126.94 mb/s. PCI bus (33 mhz) is rated for 132 mb/s. 66 mhz allows for 264 mb/s. Keep in mind, this is raw data rather then MPEG/Compressed data.

First thing to remember is that your IP Cameras need to be on a seperate network. (The DVR can be the bridge between networks.) Common mistakes: 1. Bandwith. You will need it. You will need alot of it. 2. User Access. Secure the cameras. Security guards get pissy if they find the hiden camera watching them. 3. Finding a line that fits your needs. Axis meets some needs but not others. Vivotek meets those needs but not others.

Why an IP solution?

If you want to pick nits then yes there is an analogue signal at the very begining. The second, or third chip behind the CCD is going to do an analogue to digital converison and the chip behind that does the encoding.

Video Insight. I am one of our sales reps. It explains my sig.

I don't know about Geovision. I could guess based on CPU usage but I don't have a copy of it. I know we do it and you can see the results when you run us in a SMP or dual core system.
