    I have two WiFi networks (using DD-WRT).

     

    MyWiFi and MyWiFi_Guest. The MyWiFi_Guest network is Internet only, no access to local LAN.

     

    I have a device on MyWiFi_Guest but I want to access Blue Iris through the Android App through the external IP.

     

    I tried leaving the LAN IP in the server settings as blank. I tried putting the external IP in the server settings. I used a dynamic DNS as the external IP. None of them worked (Says unable to connect/resolve name).

     

    If I connect to another WiFi network or use Mobile Data, it connects. If I'm connected to MyWiFi network, it connects.

     

    If I'm connected to MyWiFi_Guest, I believe it keeps trying to use the local IP (which is of course disallowed) and so I can't connect. Even when I explicitly state the external IP to connect to.

     

     

    I am open to other solutions. Like keeping Guest network active but allowing only that device access to the Camera PC.

    To expand on BW's comment:

     

    This camera has the IR filter built in to the lens, not as a separate component like many cams. If you put in a lens without the IR filter, your colors will be off.

     

    Many lenses are labeled IR. This usually means they're IR corrected, not IR blocking; that is, they pass IR through and it focuses at about the same point as white light, so you're in focus with both IR and white light on day/night switching cameras.

     

    You want an IR blocking lens. These are a lot less common.

     

    Also, when you use a lens made for a larger sensor, you don't get the same field of view as the same size lens for your sensor. A 3mm lens for a 1/2" sensor will give you a smaller field of view than a 3mm lens for a 1/3" sensor.

     

    1/3" is 0.33". A 1/2.5" (0.4") will give you a smaller FOV than a 1/2.7 (0.37") lens, which will give you a smaller FOV than a 1/3" lens. Each lens will give the same approximate view in different size circles of light, so your 0.33" sensor sitting in a 0.4" image will lose more of the image around the edges.

     

    Also, these sizes aren't the actual sized of the sensors, but that's a whole 'nother post.

     

    Thanks MaxIcon, I asked the guy whose thread you linked me to and he said he got the lens off AliExpress. The previous lens I bought had very off colours but the specs matched so I wasn't sure this time.

     

    So will the 1/2.7" 2.8mm lens still give me a wider angle than a 1/3" 3.6mm lens?

     

    The two I'm looking at are this and this. The lens with 1/2.7" says 109 degree angle and the one that says 1/2.5" says 114 degree angle. So which one would give me a wider view?

    Your lens sounds like it's got the IR filter permanently attached. Some cams have been doing this to reduce cost on non-IR cams, rather than installing a filter over the sensor. Most of the Mega IR lenses are IR corrected, not IR blocking, so this was probably installed by the camera manufacturer, not the lens manufacturer.

     

    I believe the popular GoPro camera uses IR blocking lenses, so you can check with people who sell accessories for them.

     

    Here's another thread with links to IR filters you can buy, which may or may not fit your camera:

    Hi, thanks for the link. That thread is the exact same problem I have.

     

    The IR Filters that you linked look like a very thick piece of plastic with the IR Filter sandwiched inside. Is that right or is it just a case/box that stores the actual thin piece of film?

    I got a dahua hdb3200c with the 3.6 mm lens but it wasn't wide enough.

     

    So I bought a 2.8 mm lens from ebay and from dealsextreme, both of which increased the viewing angle BUT the colors are washed out. They look greenish blue compared to the MEGA IR lens, my black shirt looks dark red (maroon).

     

    Where can I buy the same brand lens at 2.8 mm (or equal quality)? I noticed that the MEGA IR lens has this thin plastic red film on the back which I assume is the IR Filter while the two 2.8 mm lens I bought do not have this. Would the colors look less washed out if I put something like on the lens?

    I recently installed two of these cameras (has a 3.6mm lens I believe) and I don't find it to be wide enough. I was hoping to view from my porch to the sidewalk but it's about 2 meters short.

     

    I've read on these forums that the lens on this camera can be replaced with a 2.8mm one but I have no idea what I'm looking for. There are a few lenses for cctv cameras on ebay when I search for 2.8mm lens but I don't know if they're compatible.

     

    Can anyone tell me where I can get some 2.8mm lens that will fit the IPC-HDB3200CN Dome Camera?

     

    Thanks.

    Mine works fine with BlueIris. I can even put the camera video on a webpage via BlueIris and works fine.

     

    Oh I see, when you said "BlueIris will work fine with the first two you have links for" I thought you meant the first two eBay links to the Dahuas. But if the Q-sees work with BlueIris then that's great.

     

    I think observant people will recognize the domed style camera as readily as a bullet style as they are both prevalent. Some people are clueless and wouldn't notice either but anyone who is going to burglarize you will know to look for both types. The dome type are more attractive, or I should say, less obtrusive.

     

    I am a new Costco Q-See owner and am just getting my cameras set up. It appears the Q-See is as you said, a rebranded Dahua. They put their own firmware in the devices which you may or may not be able to substitute for the Dahua version. The hardware is the same in either case.

     

    The HFW3200C can be bought straight from China for $270 plus $55 shipping. IF you buy multiple cameras from China, I am guessing the shipping cost will be the same, i.e. you won't pay more and can split the shipping cost over the number of cameras you buy.

     

    Do you really need the zoom function? If it is going to be used for unmanned surveillance, you can probably figure out the angle you want and install or get it with the right lens for the angle you need. Why I say that is because they are going to be selling the "S" version soon. Same "guts" as the C version, but with a fixed lens vs. a zoom lens. For cost comparison the "S" version is $145 plus shipping so you can see that there is a $125 difference to get the zoom feature.

     

    I haven't considered the dome version as I know the areas I want to cover and the FOV needed for each one so I can get the bullets with the lenses I need for each instance.

     

    The Chinese contact thought the "C" version would be available some time after Chinese New Year and another source said some time in February.

     

    Aesthetics wise, I do prefer the dome-style. I didn't really think about the minimalist design to catch unsuspecting burglars. Although one could argue that the bullet style (they look pretty big and intimidating IMO) might scare off potential thiefs.

     

    Zoom I don't really care about, the night vision however I would like to have and it seems that the dome-style doesn't have night vision or at least not as good as the HFW3200C/QCN8002B. Although I do have motion sensitive flood lights in the locations I want the cameras to be.

    So I was looking at some cameras for outdoor surveillance (about 4), and after reading around on this forum it seems that Dahua is a pretty good brand. I see these two cameras mentioned around here and they look pretty good for the price. ~$300 per camera.

     

    http://www.ebay.ca/itm/2-0-MP-CMOS-Full-HD-Water-proof-IR-Network-Camera-IPC-HFW3200C-/200860295159?pt=US_Security_Cameras&hash=item2ec434dff7

     

    http://www.ebay.ca/itm/2-Megapixel-Vandalproof-IP66-Mini-Dome-H264-Network-IP-Camera-1080P-PoE-3-6mm-/200816538700?pt=US_Security_Cameras&hash=item2ec199344c

     

    Now I see that there are two primary styles of cameras, dome-style and bullet-style. Can anyone tell me the pros/cons of the two types? I like the compact and sleek design of the dome-type. Makes it stand out less (maybe people won't even know what it is assuming the outer dome is tinted). But it doesn't seem to support Nightvision. The bullet style one has like 40 IR LEDs.

     

    Aside from the camera style, I've read that Costco sells a brand called Qsee that is essentially rebranded Dahua cameras (although i've also read that they're worse than Dahua). The only reason I would consider buying the Qsee over the Dahua off ebay is that Qsee is local and should I have any problems, I could return it to Costco. Buying a Dahua camera off ebay however is going to be troublesome if I need to return it.

     

    The Qsees I'm interested in are these ones (They look the same except for the last one which has what appears to be remote panning/tilt).

    Lastly, do these cameras work with software NVR like Blue Iris?

     

    Thanks.
