Is the existing camera that is located near the exit not getting the job done, or is this new camera going to monitor the "sitting area" more closely?
The PTZ has stopped working. It is a 20 yearold Analog camera that is only black and white. He wants hi res PTZ color to secure the pool better...
The one in place right now is to the left of the exit sign.
You will have to save the image to see the full size.

The Dotworkz Tornado series is the best one for high humidity. Well sealed, very efficient fan.
We re visited the site and the PTZ is a must.. I still am not sure why.. the only thing I saw happening today was a 80 year old woman alone doing aquafit with a cd player by the pool.
Yes it is linked to TV in his office.
I agree with all the statements. We have told him the cost is not worth what you will see. At the end of the pool their is a hottub that is it. There is no real reason to have the PTZ other then the wrong reasons. But This has to be put on paper for someone higher up to say yes to. Hopefully that is where it gets shut down and that the proper solution can then be put into place.
I have informed the Property Manager who is a very nice woman.. who is the Boss of Mr PTZ about the other options for viewing that area with thanks to all of who commented with great ideas on here. :)
Ross, here's feedback from Axis: "Any thing -E will be sufficient. The -S is best fit because it's pressurized if they want to go that route ."
I am not sure if you really need -S / pressurized but it certainly comes with a big price premium - in the order of ~$2,000 more.

In this case, just like you pressurize waveguide for microwave, I would use an outdoor rated pendant ptz camera with a wall/ceiling mount and, with the cable run (or maybe with piping used for the cable run) I would run a fan device to slightly "pressurize" the enclosure with non-humid air (from another room?). Would not take much constant air, probably 5+ PA of pressure in the enclosure. May need to use some silicon or foam on the neck entry.
You can get Vivotek or Hikvision IP PTZ pendants for $800-$1100 integrator cost or Panasonic/Axis for $1500-2000.
This Flir guy wouldn't recommend thermal for a few privacy reasons as well as an inability to see someone under water. I might recommend a 2.1mp PTZ with IR illumination and 30x optical. But.....that's up to the integrator.
Rukmini, First I should say it is a real Flir product but I was kinda kidding. It's way overkill. ;) Second, a thermal will stop seeing at the edge of water for the most part. Third.....many swimsuits would become almost transparent to thermal so it's a bad idea. Wet or dry. Lastly......I would go with HD cameras that were fixed to reduce the likelihood of lawsuits and provide coverage for theft and possibly drowning if a lifeguard isn't present. Maybe Todd has an HD-SDI that would work over the existing cable and monitor? Just my opinion though. Greg
I realise this is not Axis and they probably have a version of this but have you had a look at the Pelco Pressurised Spectra IV SE?
This style of PTZ is pressurised with nitrogen and is good for humid climates (environments) also as the dome is 316L stainless the fumes from the pool chemicals won't melt traditional aluminium enclosures. While their models only show as analogue only they can do what's known as an SMR to get an IP version created. Its standard def.
Just took a quick look on the Axis site and the Axis Pressurised PTZ is Q6042-S and its construction is similar. Sure these dome cost more than regular PTZ's but you won't be dissapointed with its longevity in this environment.

Is the pressurized n2 in aid mainly of the moving parts of the turret and lens, i.e., in a fixed MP camera with no mechanical assembly is it still recommended? How is pressure maintained?
The nitrogen pressurised enclosures are to create a dry (no moisture) environment inside. Whether its a PTZ or fixed enclosure they're great for humid climates and harsh environments. Of course because of the higher cost and the fact you have to purge the enclosure onsite the entire experience costs more than regular CCTV enclosures/PTZ's. You need food grade nitrogen in a cylinder, hoses, guages etc etc. Make sure you check your MSDS on the use of the gas and cylinder in your country as I could never the ones we sold from the US factory. As an ex Pelco sales guy I use to sell these products more to harsh environments, humid climates and also to industrial and resource clients. These kind of clients can afford the added costs.
As these enclosures have special seals the pressure is maintained and due to the nature of nitrogen having larger molecules than oxygen it holds pressure and doesn't change temp much. Race cars and some aircraft tyres use nitrogen for the reason of reducing the tyre's running temperature, keeps tyre pressures more constant, slows the rate of pressure loss and doesn't react with the tyre and rim materials (no moisture). Apply this to camera enclosures and you can see the benefits.
I can't comment about the Axis but the Pelco units (including the EH8100 series) have the ability to report low pressure alarms.
