Exactly, notice that he is identifiable once he gets to the side of the frame, same deal with Longse if you are off center hot spot it's better

3rd times a charm on this one , 1:55 again
 
Sent a note to Eddy to see if they could decrease exposure time.
 
Checked out my low mounted wide angle Huisun and it exhibits the same thing.

I turned off flood light, so it's pretty dark in there and about 40 feet from where I am standing, just the IR which is too overpowering in close range. I either need to mount it higher or... well, no other option really...

I can think of at least two options. The cheapest is to trying blocking off or disabling one of the two LEDs on the camera. That should improve closeup shots (the real money shots) but worsen medium/long distance shots. The second is to mount an external illuminator or two and aim high so that it lightens the background or targets in the distance but not the foreground. I've had success with improving blown out closeup shots doing that. Two would allow you to illuminate high and to the sides. Brightening up the dark distant parts of the scene should cause the gain control to back down and darken light targets, hopefully getting them in the range where you can get good detail.

If Longse takes requests for firmware adjustments maybe ask them if it is possible to detect sudden hotspots, particularly in the center, and adjust the exposure or gain for them instead of the rest of the scene. I assume there isn't something like center or region weighted exposure or gain control already in the firmware somewhere?

Thanks for the walking shot BTW, much appreciated.

I think smart ir is just a gimicky name for auto exposure. It's probably not increasing the exposure time enough.

Same kind of issue here, go to 1:55

You camera is adjusting to the scene but it does it very slowly (takes 20 seconds after you leave the scene quickly from up close) and seems to do whole-scene averaging instead of center or hotspot weighted. Not enough dynamic range to not blow out the subject when there's that much dark background and black sky in the scene. Pointing the camera down to eliminate the sky and have separate illuminators to lighten up the background should help even out the scene lighting a lot.

I am going to be mounting Huisun 10 feet above it, so I'll just mask the IRs on Longse. It's not a big deal though, it's still identifying at mid range.

Frankly I haven't tried it in NVR, I set it up in Longse UI and it works extremely well unlike Huisun

(newbie alert) So if you can't set it to do motion detection in the NVR, what can you do? I have same issue with the Hikvision 7616 and a Foscam ... when I try to mask a section is says not supported, but it works fine with the Analogue cameras from my old system (which is why I didn't use Blue Iris). Would like to use third party IP cameras

You need to do it directly on the camera web GUI itself. It's possible to do some camera configuration via the NVR when the NVR specifically supports the command set of the target camera, usually from the same brand as the NVR.
I didn't think Aussie humour was that subtle.

If you set the motion detection in the camera, doesn't that mean that you have to set a network address to store the clips, that will eventually fill up. Currently running the Hikvision recorder for the analog cameras and Blue Iris for others, and trying to choose between them for longer term.

I'd guess the masking operation is performed in the DVR on an analogue system - assuming (maybe a big assumption) that the cameras only have a basic set of configuration options.

Certainly if you want to do motion detection recording as opposed to continuous recording, you need a method for the camera to communicate the 'motion detected' event to the NVR so that a recording action can be initiated.
Same brands of cameras and NVRs have compatible and somewhat proprietary protocols for that, or the NVR has specific designed-in support for a particular brand/model of camera.
But what can work if the camera supports it is the ONVIF standard for event notifications, which is well supported by Hikvision.
 
I actually mounted my huisun PTZ and IMX178 near each other and used the PTZ as an artificial IR illuminator for the IMX178. I can quickly tell that this IMX178/longse camera is likely a case of 'great sensor/poor illuminator' as when I use the PTZ to shoot light far away within the IMX178 scene, the far away image from the IMX178 becomes significantly sharper. The trick is dialing in the brightness of the IR from the PTZ to match the exposure at different distances within the scene of the IMX178. My guess is that with 2 or 3 illuminators, you could dial-in a very sharp, wide range with this cam if you effectively threw out the stock IR.

To better explain, here are a couple links originally posted by @SyconsciousAu which I found extremely helpful and illuminating (no pun intended). They effectively validate what I'm finding experimentally, namely the concept of the derwent lamp - specifically that your illumination follows the inverse square law WRT distance from the aperture.

yeah IR is powerful in Longse, but not much adjustment. Can't turn off and can't adjust power, which is common in most budget cams. I am pretty sure the IRs were initially designed for 5mm lens.
 
This camera looks like the camera I want, however, I would like for it to be H.265. Alibaba has H.265 on the page but the specs on the Longse website say that the camera is strictly H.264. Does anyone know if a H.265 version will be released soon? Or a comparable H.265 similar camera?
 
Why do you want H.265?

Actually, let me rephrase that, as I can understand why H.265 has it's slight advantages. Why is not having H265 a deal breaker? Storage is so cheap nowadays.
 
@NIPSZX - looks like the unit I have will do H.265 according to the menus. When I use the option it continues to display via the camera's web interface, however I can't verify that because it appears blue iris does not decode H.265 so BI reports a no cam signal error.

For me, the biggest benefit to h.265 would be reduced network congestion and the ability to use more high megapixel h.265 cams on existing or cheaper 10/100 switches. Not a deal breaker in many cases but it has other advantages besides reducing storage requirements or significantly increasing the days of storage capacity of, say, a single HD NVR.
 
You can refer to post #1 in regards to h265
 
I'm thinking about purchasing the camera from this seller
http://s.click.aliexpress.com/e/Ok8yDWu

I can't seem to find a seller that is selling the camera with a 3.6mm lens. I sent them a message asking if it was possible to purchase the camera with a 3.6mm lens.


It states that POE is optional, I also don't see an option in the listing to include POE when I order. (I've never ordered from aliexpress before)
 
@smiticans - I've got a 3.6mm/poe version I may be interested in selling if you're looking for one, just shoot me a PM. I like the S500 camera a lot but I think I'm going to standardize on the 5-50mm huisun ptz for my installation instead as it's more flexible in deployment.

POE is optional and it's external module on mine, you can see picture I posted in early pages. As far as which seller to get, last time I checked this seller didn't have 3.6mm option, but maybe he does now
