    If, for whatever reason, I wanted to use a lense that had auto iris capabilities on a camera without that function, what would be the best way of holding the iris open? Do they make such a device? Thanks

    IP cameras, i.e. Axis 232D will require quite a bit of current to operate correctly and I would not recommend using any spare CAT5 pairs for this function. Now, all control functions are via software commands via your viewing/recording software. You can control the functions via either the mouse or a joystick. You will need the correct software for the camera. Axis supplies software for its camera that has all of the controls built in. Other NVR solutions must integrate the Axis software into their program. This goes for all IP cameras. You will need to check with your NVR software supplier to make sure they support the camera you are interested in. I have experience with the Axis PTZ camera and it is excellent. Experienced operators will notice a difference in operation between the analog PTZ and an IP PTZ camera because of inherent delays for the IP camera called latency. The amount of latency is dependent upon many factors. They will get used to it.

    Take a look at my reply under "top 10 NVR..........etc." I don't know what kind of business this is in but you can save a load of money with the existing LAN. I also don't know how many analog cameras you have in place. With the LAN I'd take a close look at IP cameras. Try Axis or IQinvision. Encoders will add enough cost to ALMOST offset new IP cameras. Good Luck

    I'm surprised they don't list supported cameras, encoders, etc. Actually, they will integrate any camera/encoder you want to use. We ended up using it after much research, and many demo's. There are others, and they are all very similar. This is an emerging market and I think we are just seeing the beginning. The problem is that many casinos are heavily invested in analog and it is hard to justify the additional up-front costs. A new casino is the ideal time to make the switch. The big initial cost is for storage. As HD's come down in price things start getting interesting and competitive. There is really no comparison between analog video and IP video. Give them a call and I'm sure they would be glad to offer a demo. You can see them at IPSEC2007 in Birmingham this year, as well as most other major shows. Good luck in your endeavor..

    Take a look at Petards UVMS. A UK company with office in US. We're using it at several Casinos. Also using it in high-end residence in FL. They just integrated Immervision (canadian co. that makes 360 lenses.) Works great. Take a look at Immervision, it is very cool and will replace Ipix technology, IMO. We're running over 1000 cameras at one sit. Also, have one 100% IP site with over 400 cameras.

    That's right Collin, us Okies aren't tooooo backwards.

    Another ground loop problem can come up when the electricians ground things to two ground rods, seperated by some distance. As the ground dries up a difference in potential can occur between the two grounds, causing ground loop problems. Solution .......100% IP.

    Collin, running on 24VAC accentuates the ground loop problem in my experience. If the ground point is different between your PS and the actual equipment ground you WILL have ground loop problems. i.e. equipment rack is grounded to building frame and PS is grounded via UPS feed. You would think these two points would be at the same ground potential... but not always. If there is a difference between to the two points you will have ground loop problems. Try floating the power supply from the rack (Altronix rack mounted) and see if it doesn't do away with the problem.

    Something you might not know.....the POE switch outputs 48VDC. The end device regulates that down to the required operating voltage, internally. This would probably allow some voltage drop on the CAT pair before you reached the needed voltage for the end device. POE injectors are located at the far end and accept a RJ45 with a continuing RJ45 to the camera. Internal to this device is a regulator, usually switchable between 5 or 12VDC to feed the cameras external power connector. This way you can use a non POE camera with a POE switch.
