At what temp do you need a heater on the camera?
Huviron replied to Nodon's topic in Security Cameras
We did cold chamber test for the Russian market regulation. All of our outdoor cameras were managed to run at -50 degrees celsius (-58F) without heaters We still have almost none temperature related issues even in Russia. With heater, it may help a little, but in most cases, heater is just a ceramic resistance which is not very effective at extremely cold weather. Hope this help! -
Looks pretty good only with internal IRs. I can clearly read the letter "ROVER" from the hood. Just wondering how dark it was when you take this picture? Was it pictch black? Also did you turn on the Burst mode "On" for IR settings? It is in dynamic LED "Mode1" Right? Thanks for posting BTW!

Specotech Intensifier Outdoor Cameras - Cold weather
Huviron replied to zardoz's topic in Security Cameras
Most good-quality outdoor cameras come with built-in heaters inside, so cold temperature should be no problem. Intensifier (AKA Senseup, DSS, Digital Slow Shutter, etc...) is a special image proecessing uses digital slow shutter speeds in order to allow extra light into a cmaera so you can take images at extreme low light. These cameras uses very strong digital noise reduction so you can still see pretty good images without seeing too much noise at night. However even with this cool feature, it's hard to catch fast moving images just like you take pictures with your digital camera at night using very slow shutter speed. You will need to use flash light. With Intensifier or Intensifier2 (AKA Senseup, DSS, Digital Slow shutter, etc...), you will take good pictures at night but with IR you will take better pictures. There's no magic. Speco Intensifiers are very good cameras. If you like Speco cameras, why don't you buy their Intensifier line with IRs? Looks like they have one with IRs. Hope this helped! -
Huviron / Sunkwang SK-N190XAI/R1 whats it like?
Huviron replied to DeDanan's topic in IP/Megapixel Cameras and Software Solutions
I don't know if anybody support it ( 3 rd party VMS) their own soft kinda suck few years back was thinking to add them for stock happy today that it did not happened too many other choices avail today my 2 c I'm sorry to hear. Well, to be honest, N190XAI is now one of the older models. We first introduced N190N & N190XAI quite a few years ago when there were not many IP solutions to choose from, so we had to make our own solution. However, IP cameras haven't been really improved since then, so N190XAI is still widely used. But we already have newer models like N110H's & N510H's so N190N & N190XAI's are more like budget IP solutions now. Hope this helped. -
bantham1, Glad that you found out the solution. I just checked this post. Sorry about late respond. Under Dynamic IR settings, Mode1 is regular dynamic IR settings. Changes IR brightness according to distance of the object and environment brightness and etc. Mode2 is more complicated. In this mode, IR birghtness changes as well as it uses WDR and senseup. It will try to stay without IR as much as possible and it will eventually turn on the IRs at the pitch black condition but with WDR on. This will be useful when you need to see something not reacheable with IR. (Especially objects on the corners) But you get slower frame rate and more noise when you use this mode. Hope this helped. Let me know if you have more questions.

Huviron replied to DeDanan's topic in IP/Megapixel Cameras and Software Solutions
Well, it's our camera so...... should be good. If you have any questions, please send me an email. I will be glade to help you! jay@huviron.com -
It seems like IR light gets reflected off either dome cover or fog(?) or some sort. Check if there's any fog at night or moisture buildup outside of dome cover. I've seen some poorly designed IR dome cameras have scattered reflection issues like this. Hopely this is not the case for you though.

TV Line Debate. Important or Over emphasized?
Huviron replied to SEANHAWG's topic in Security Cameras
This was my whole point when I tested high-resolution cameras. Thanks Sean for this topic. Max resolution you can record on current DVR is 720 x 480 (NTSC) only when the DVR support Full D1. Some of our 550TVL cameras has efffective pixel ratings of 768 x 494 (NTSC). Heck yeah this is already over the limit of current DVR. I can still see the difference between our 600TVL cameras and 550TVL cameras on DVR. But not because of more TVL, it's because of features on our 600TVL camera like WDR, TDN, SENSE UP, better CCD, and better DSP will help to produce better picture quality, colors and etc at any situation. Will our 700TVL camera has better picture quality than our 600TVL camera? Well yes but still, not much. Good cameras will produce good pictures at anytime, anywhere, in anycondition while bad cameras will fail. Please do not judge cameras by TVL, I still believe our 550TVL cameras will produce better pictures than some cheaply made 700TVL cameras. -
Effio-E is (650TVL) lower-end version of Effio and it lacks alot of key features from Effio like WDR, TDN, Dual-scan CCD, Face Detection, 3D DNR, and etc., and is very high-lux(0.1) since it lacks ESS.Will probably fit in between 500TVL's cameras and high-end 650-700TVL Cameras but most people looking for EFFIO will probably look for High-end features like WDR, TDN, 3D DNR, low-lux, AGC, ESS and stuff. There are a lot of choices for 600-650TVL cameras if you don't need all those features. I'm not really sure how Effio-E will compete in the market but so far Effio-P definately gets more interest. Hope this helped. Huviron - not sure where your info about Effio-E is coming from, but "it ain't necessarily so". We have arange of Effio-E's with WDR, Day/Night Low Lux (0.01lux @F1.2), OSD, ATR, etc. Not 3D DNR, only 2D though. It's all in the overall chipset (CXD4127+CXD4816+ICX673AK/IC672AK). Our Box is $73, Indoor Dome w/3.6mm Board Lens is $71, and Vandalproof Outdoor Dome w/4-9mm varifocal lens is $119. Let me know your email address if you want any. I got all the info from our Engineering team. We manufacture Effio-E cameras as well so I don't need your cameras. Thanks for the offer though. I'm not saying Effio-E DSP is bad, but I just don't see any advantages of Effio-E over other cameras yet. I don't know how many times I have to tell this but here we go again. Effio-E does NOT have true WDR. Don't confuse DWDR with true WDR. DWDR is just gamma compensation. Let me know your email if you need true WDR cameras. And one more thing... **Please do not advertise your price on this forum. This is not the place where you can post your price list. ** Hope this helped. Thanks!

I don't think Effio-P has production code yet as it's still ES status. Only Effio CXD4112AGG (DSP:CXD4112AGG) and Effio-E CXD4127GG (DSP:CXD4816GG) have production code so far. Please correct me if I'm wrong. Hope this helped.

Yes, looking forward to your tests with no IR. Best, Christopher OK here's the test result with NO IRs. Sorry I forgot to turn the monitor off!! But you can still see the difference very clearly. Look how clear Sony Effio is at night(CH1) and Pixim(CH3) shows quite a bit of noise on the picture. Again Gen2 (CH2) kind of in between two.

I don't know how they implement Digital WDR in CCTV cameras, but it digital photography, HDR (high dynamic range) images are made by combining two or more images of the same scene that are taken at different exposure settings. So, some of the pixels in one image may be overexposed, and some other pixels in another image may be underexposed. The HDR application discards the under and over exposed pixels and selects pixels that are properly exposed. Using this technique, it's possible to create images that would otherwise span far more stops than can be recorded by the sensor in one shot. It would be possible, for example, for a CCTV camera to take two consecutive images, one at 1/60 sec and another at 1/120 sec, and combine them. Don't know if that's how it is actually done, but something like that is possible, and would significantly increase detail for scenes with wide dynamic range. Best, Christopher That is exactly what our LWDR do. With single scan CCD, it cuts one frame into half so first half the frame it takes one exposure in dark area and correct gamma value, and next half the frame it takes one exposure with bright area and correct gamma value, then the two exposures are combined in the nex frame. Basically this is why we call it LWDR (Low-Frame WDR) and obviously frame rate drops to 1/2 of the normal frame rate. There's more advanced way but more expensive solution. We can use dual scan CCD like the one from Sony Effio so it take two long and short exposures at the same time basically saves 1/4 frame rate from single scan CCD WDR and total frame rate only drops to 3/4 of the normal frame rate. A bit smoother pictures. We call this SWDR. DWDR, however, is manipulation of digitized picture in the camera. "It may make the output of camera looks better ( if it does work). but won't provide any extra detail." This is totally true, but there are more good things about DWDR so manufacturers can't totally ignore DWDR. Most important thing is, DWDR does not drop any frame rate so pictures still look smooth and DWDR can be used with DIS function while real WDR can't use them at the same time. Hope this help you guys.

Sorry to bring up the old post back. While I was testing Sony Effio and Huviron Gen2 DSP, I did a quick WDR test for you guys. Since Huviron Gen2 DSP support Both DWDR and WDR. I took a few pictures with each on/off Both WDR off DWDR ON High LWDR ON (True Mechnical/Low-Frame WDR) You can clearly see the difference.

Squizz, Sony 960H Super HAD CCD II on Effio Sony 760H Super HAD CCD II on GEN2 Obviously DPS Sensor (CMOS) on Pixim We will be at the ISC East this year as we have to support our OEM customers. I believe a couple people from our Headquarter(Korea) will go to CPSE. I just double checked and Eric will not be at CPSE this year. Thanks Jay
