Theiatech's online calculator will do that, http://www.theiatech.com/calculator.php, and they have Android and Iphone apps, too.

Forgive my ignorance (I live in an area where people panic below 0C), but how is your stream still running at -20C?...I guess it still stays running at some depth below the surface ice? Seems pretty neat, overall- I was wondering if the load dump could be (or is already) a separate element in your water heater, to be able to gain heat from that, instead of being wasted?

Pelco seems like a good brand, however i am having trouble finding it on google. Do you have a supplier that sells this Pelco? (US) Thanks Unfortunately, I think it's been discontinued. I have been trying to find out who OEM'ed it for them (I'm sure they didn't build it themselves), but so far, no luck.

Q-Star systems (http://www.qstartech.com/products) uses a Canon point-and-shoot camera inside (I've had one apart). Our city bought quite a few of them for graffiti and vandalism...No great success story with them, though.

VideoNEXT http://www.videonext.com/, and Vitamin d http://www.vitamindinc.com/features.html are Mac based. I tried out a demo of VideoNEXT, it seemed to work pretty well.

I also use the Pelco one. I tried the monochrome model shown earlier, and it was crap in comparison to the Pelco one (model CST150)- Have had to repair the cable on it a few times, though.

I used to be an auto mechanic, so I've literally been "into" a whole lot of cars..... Right now, I have two older BMW's, a Toyota 4Runner for rock crawling, and a one ton Chevrolet 4X4 to pull other toys... I suppose that counts as a yes?

Both Milestone and Exacq have pluses and minuses associated with each of them. I prefer Milestone's remote client (significantly more features, and ease of use), but it is limited to a Windows platform, where Exacq can work on a variety of platforms, including mobile. Milestone's remote client will function better over a low bandwidth remote connection, as it has options for downsampling resolution, where Exacq requires downloading a clip before viewing it (the web based viewing can use reduced bandwidth, but at the cost of very limited features). Exacq tends to be limited almost completely by just disk storage speed (I've run multiple megapixel cameras with it on a Via Epia mini-ITX motherboard), whereas Milestone requires significantly higher amounts of processor capability (both manufacturers have calculators on their sites for system design). If you are thinking about moving between different servers on Exacq, you can license the MAC of an external USB NIC, so it can be moved between servers as needed (Exacq can move licensing between servers, but they do charge for it). Milestone licenses by the camera MAC, so changer servers is not an issue (although licensing and changing cameras requires visiting the Milestone licensing website). Milestone does charge by channel on licensing (the Arecont camera you have would license as four channels), although their Essential version is $49 MSRP per channel, so it's not too expensive.

I see a lot of headaches coming. As devices that were previously (somewhat) protected by routers from internet attacks will now be fully exposed without NAT/firewalling (and more and more devices become internet-enabled), we may soon see our toasters and other home devices trying to spy on us, kill us, etc.... BTW, at the Black Hat conference recently, a guy showed vulnerabilities in a body-worn insulin pump!

If anybody is looking for a list of RTSP URL's to be able to connect to different brands and models of cameras, I found a lot of them here.....http://www.soleratec.com/rtsp/

Milestone Corporate supports multicasting, which would reduce bandwidth in the way you are asking, but only for live viewing, playback is in unicast. Not sure if any manufacturer supports multicast playback, I'm not sure if that would even be technically feasible. Also, if you want to enable multicasting to reduce bandwidth, you will need to have all sites linked with VPN tunnels (layer 2 connectivity between sites) to allow multicast traffic through (and, all switches in the path would need to support IGMP).

Instead of using a remote desktop program, try using a VPN program like LogMeIn Hamachi at both ends (I'm assuming this is a PC based DVR, since you mentioned trying other remote desktop products), and then use the remote client software to connect to the remote VPN IP address.

Hey, thanks for thinking in Metric already! " title="Applause" /> You're welcome.. Since I'm left-handed, I get to use the metric system on measuring cups a lot, too! I finally got a left-handed one that came from Canada- Proof to us Americans that you Canucks are backwards!

Yeah, you guys think you are tough because you can handle -40C.... Come here to central California and see how you do at +45C When the soles of your shoes start sticking to the asphalt, you might rethink your evil plans!

The T1/E1 crossover connector pinout is different than an Ethernet crossover cable, try it with a proper crossover connector or cable.

You'll want to use lower frequencies (2.4Ghz, or 900Mhz), 5.8Ghz is blocked by even slight obstructions in the signal path. I have had good success with Ubiquiti 2.4Ghz products (I used the NanoStation M2's) penetrating a reasonable amount of foliage, but it will always be best to try it before you commit to the install (nice thing about the Ubiquiti products, you can get a pair of the NanoStation M2's to test for around $160.00 or so!).

Besides the above comments, a "T" tapped connection is likely to have ghosting in the image if the lines out from the "T" are of any significant length. If the DVR has a looping output (many do not, though), you could use that to go to the monitor. Make sure and have the 75Ω termination off at the DVR, and on at the monitor, though (if you are using a standard TV for a deterrent monitor, they often have a high impedance composite input, a terminator added at the monitor can improve the image) A powered splitter is usually the simplest option, though.

A reset will not hurt, but you will lose all customized settings, make sure the user can walk with you through the process of reprogramming the mux (most specifically, the Coaxitron settings). Pressing and holding the individual camera number buttons on the mux is a fast way to get to those settings. Also, the mux must be set to "spot" on the keyboard, and the correct camera called up, to operate the Spectra's. One other thing to check would be to see if the keyboard controls any of the mux operation at all (changing camera outputs, etc.) If not, a reset might be in order.

Are you sure it is a KBD300A, and not a KBD4000A? I thought the KBD300A was only for matrix/direct wire operation, and the KBD4000A was for direct Genex control. Anyway, you might check the programming in the Genex, and make sure the Coaxitron control is set for extended (32 bit) operation, not standard (16 bit) control. Manual here, http://www.global-download.schneider-electric.com/852575770039EC5E/All/873F27146A0F677485257633005C69E7/$File/c1995ma.pdf, Page 37 for PTZ settings. You may want to try a complete reset of the Genex, as well (page 44).

Your best approach might be to take apart one of the remotes, and wire the access control normally open output to the pushbutton switch contacts in the remote, and locate it somewhere close to the door operator. If you wanted to get fancy, a lot of remotes use small 12 volt batteries, if yours does, you could use power from the ACS to power it, so you don't have to replace batteries periodically.

I use this one from Nitek, http://nitek.net/products/accessories/IPT148.htm, it came packaged with a demo kit from Arecont, and I've bought a few more for our other installers.

Can you share some more information about the construction/size of the car park? This could be feasible, but would possibly require locating multiple AP's in the structure (if you can't wire cameras in the building, you might not be able to wire AP's there, either...). Also, we'd need to know the battery capacity of the carts, to see about the additional load of a camera and transmitter. If the carts are all moved to a centralized location for charging overnight, you might be able to use cameras with onboard storage, and then offload it it at the end of the day while charging.

Hmmm, no, but I ordered one recently to bake (yesterday here 104F, today's forecast ~107F) If they create more internal heat than the ACM/TCM series, they might have problems here.....

You try to calculate storage requirements? I just tell them it's like asking how long is a piece of string. You won't know until you get it. HDD's are pretty cheap these days so it's not that much of an issue adding additional capacity. This particular customer needed over a year of storage on certain cameras (11 out of 39 cameras), all Sanyo's, so yes, you have to at least start somewhere with your disk sizing (32 TB planned originally, now growing to at least 64TB due to the frame rate issue).

I really like the Sanyo's, and have installed a lot of them. One thing to keep in mind about the lower models (VCC2100/2300 and VDC3100/3300) is that in H.264, you can only select streams at either 15 or 30FPS, no lower rates are available. This bit me when calculating storage requirements on a large job, I had been expecting to be able to set frame rates at 5 FPS or so, which is available in the higher models.
