LOL - it does look like one big house, but the way the houses are situated, along with some well placed trees LOL, that is actually like 10 houses away from meThats a big house!
i use it on smartpss, pic is bit good.
This review was the 3mm lens (Thermal 3.5mm, Visible 4mm).Hello, couple of questions.
1 - Is this the 2mm, or the 3mm version being reviewed here?
2 - Will the Thermal image (green image) produced by the camera, be displayed just like any other cam, on a 4x4 grid of any Dahua NVR?
Thank in advance
Luis
Thank you wittaj,This review was the 3mm lens (Thermal 3.5mm, Visible 4mm).
The thermal image (whether it is green or any of the other color flavors) will be shown on an NVR and displayed like a camera in the grid view (obviously with the thermal colors).
Keep even though it is one camera, it is considered two channels in an NVR. So if you have an 8 channel NVR with 7 existing cameras, you will only be able to use either the visible or thermal camera.
Field of View | 2 mm: H: 87.8°; V: 63.8°. 3.5 mm: H: 50.6°; V: 37.8°. 7 mm: H: 24°; V: 18° |
Field of View | 2 mm: H: 94°; V: 72°. 4 mm: H: 71.2°;V: 52°. 8 mm: H: 33.4°; V: 25° |
Thank you wittaj,
Apparently there are 3 lens versions of this cam. It seems the field of view and lens mm, behave somewhat different from a regular camera.
On the thermal side thats fine, hence there are probably different mathematics needed here, But on the optical side, it also seems unusual.
Would you have an opinion on this?
1- The Visual field of view does 71.2 degrees @ 4mm ( seems pretty narrow for 4mm).
2 - The thermal field of view gives you 50.6 degrees @3.5mm. (extremely narrow compared to conventional 3.5mm)

Considering the 1/2.7 sensor it strikes me as perfectly reasonable.The Visual field of view does 71.2 degrees @ 4mm ( seems pretty narrow for 4mm).
I haven't had this new model long enough to test it with a hot day equal to or above body temperature, but it performs better than my older model, so I would assume it would do the same.@wittaj Questions:
#1: How reliable is IVS (% of false alarms) for human detection during the day? Especially a really hot day. Can the outside ambient temperature be hot enough to make humans invisible to this camera?
#2: Same question for detecting animals during the day.
You are correct. My bad, I meant 50 degrees for the 3.5mm, (on the thermal FOV), seemed narrow to me. To which wittaj cited the 4:3.Considering the 1/2.7 sensor it strikes me as perfectly reasonable.
Very interesting, I may grab one.Thanks @wittaj great review, we can also change the color mode on camera. Can make it too green.

Yes it can run in fusion mode.Very interesting, I may grab one.
Is it capable of running in fusion mode? e.g. superimposing the lower resolution thermal image on the higher resolution optical image to make it appear like a higher resolution image with thermal capabilities? The image on the left is so good that it appears to be fusion.
It looks like the bullet version of the camera. I wonder if that is a typo price? Or maybe an older model version?I just caught this thermal camera on Andy's web site. Its specs are close to identical to the TPC124X-AI, at half the price. Is it new? I can't find a review of it on IPCT.
