OMG Thermal!

It makes you wonder why they don't have these, with matching zoom lens on the PTZ to aid target tracking.. have two other cam's zoomed slighly further out from the PTZ's main lens and these can advise where it needs to move to keep the target centered.. .follow behind trees etc

even better would be if you could pull this back to a NVR or software which would decide that your one target had become two and send another PTZ to follow the second

Yeah much like the one I had (gave to a buddy for his farm) one measures temp and displays it. The other sees but doesn’t give you temp readings

Is there any downside to getting the temperature measurement camera instead of the other one? Are any important features lost?
 
I only played with the one, and not that long. The downside of the temps one I had was no IVS only MD. But that actually worked fine for me as the thermal doesn’t see leaves and shadows nor bugs that well

I thought I had read that, but the specs section for the thermal camera says this:

Which is why I'm asking about this in the first place. Maybe a mistake in Andy's specs? I pulled the Dahua spec sheets for both cameras and they both say IVS is in there, but the available lens sizes are different: 2mm and 3,5mm with Andy, and 2mm and 7mm on the data sheets.

On a non-US Dahua page, there is a 3.5mm listed. And it also lists tripwire and intrusion.
TPC-DF1241-T-S2 - Dahua CEEN Region

So I'm as confused as heck. I'm going to ask Andy over on his fall sale thread.

It may be he's selling newer models. The ones we bought cheap off the guy on Ebay were from 2001 Covid era

there is full IVS for each channel on my thermal (bought from Andy, TPC124X-AI-S2).. supported tripwires and intrusions...

One more thing for people interested in thermal (especially the cheapest models from Eureka line, which is sold by Andy)..

Don't buy those cams for normal video functionality. Only for thermal one.
Those have very shitty small image sensor, very closed aperture and very bad image processing.
Even using IR performance at night is bad.. Any 5442 will kill & eat for breakfast those cams at normal video performance.

Also don't buy 2.8mm version as replacement as normal 2.8/3.8 turret mounted on totally dark back of house.
I did this mistake and now I known that this cam is not for that. Again any 5442 works better for those situations.

This cams shows own value when You want to monitor 'heat signatures' (like animals & people) at bigger distances inside some bushes / forest where normal video cams don't see anything.
For that use more zoomed versions..

Thermal sensor have very low resolution: 256x192 in Eureka line, 400x300 in Pro series (much higher price)..
Yes, they need only a few pixels to catch any animal movement, but remember: You need more zoomed version for Yours monitored distances...

Just bought one off eBay and it arrived yesterday. Not mounted yet. Primary use is to identify activity at night down my 300 yard long driveway. I had picked up an old FLIR model FC-313 cheap, but can’t get my Dahua NVR to motion detect with it. The NVR just fails to save the settings (connected using ONVIF). I will say that the image quality on 5421 thermal is WAY better than the FLIR cameras’ 320x240 sensor. That could be sensor degradation from age on the FLIR though. That’s going up on eBay as soon as I get the Dahua mounted.

I too was looking at the available firmware hoping I could flip it to have IVS.

Also I couldn’t find the thermal color pallet settings. Need to poke around more.

I'll chime in. I have a new affinity for the thermals. Love them. Have three TPC-DF1241-T-S8's. The -T version allows temperature alarms to be set, along with Fire Detection, Cold & Hot Spot Trace, Human & Vehicle Classification, Smoking Detection and Call Detection (on a thermal?). As I install all Andy's cameras for a living, I will be incorporating thermals in to higher end systems, as they cannot be tricked for intrusion events, temperature events and the like. It's like a FLIR on an Apache gunship. No hiding, unless you cover yourself in mud! I would conservatively say I have over 200 cams in service throughout Upstate NY, with over 25 customers. Low end to high end. From the original low light destroyer, the Dahua Starlight Varifocal Turret IPC-HDW5231R-Z, to the ultimate SD8C845FG-HNF AI PTZ. Zero problems with any of them in the last 8 years. I plan to put the thermal on my pool. I love to know the temp of the water at a glance. These cameras shine when you need fire detection with high ceilings. Real world situation would be the JMA Wireless Dome that Syracuse University plays in. With a 165' roof above the playing field, smoke detectors are not viable for detecting trouble. These cameras in milliseconds detect fire and sound the alarm. Another real world use of the -T series is temperature alarms. Imagine your local Waste Management has a bunch of conveyor belts with serviceable bearings. A properly greased bearing runs at 140-150F. A roller bearing needing greasing runs about 180-190F. A "shot" bearing needing replacing runs hotter than that. For the corporate world, the cost is trivial, and one camera can save millions (it's true, there was an incident). Incorporate a thermal with any AI PTZ and AI NVR, and you have casino like detection, deterrence and observation. Granted they are not for everyone as the price point is above a pro-sumer levels, but they are awesome for what they can do. With that said, it is so hard to beat the value of the IPC-HDW5442TM-ASE-S3. They are the new standard for low light situations, price point and consumer level systems. They are the bulk of my installs since they came out. The Color 4K and the 4K-180T are gaining traction as well for their capabilities, but it's hard to beat those 5442's. Rock on party people.

Sounds like the TPC-DF1241-T-S8 could be useful to detect hot boxes on rail cars to give pending derailment warnings.

Following up now that I’ve mounted it and had time to poke around a bit more. I need to download the plugin as I suspect the thermal pallet controls are hidden in the plugin? I’ve setup motion detection recording, but my NVR never triggers?
