    I just clicked on the link you provided and that was the price shown. So what are the update specs? Are they significant?

    Not all 2MP cameras are equal. IMO, most are outdated, but some are not. The Starlight models use newer, bigger image sensors. The bigger sensors (1/2.8", or the even bigger 1/1.8") result in larger pixel size (so more light in every pixel), and the newer back-illuminated design allows the sensor to capture more of that light. What's outdated are the consumer-grade cameras that use the smaller 1/3" image sensors with the older front-illuminated design.

    The challenge with today's higher megapixel cameras is that even with larger sensor sizes, the extra megapixels result in smaller pixels with less light in them. Dahua's 1831/2831 8MP models are about as good as it gets when it comes to higher MP, but they're still not as light sensitive as the 2MP Starlight models.

    Dahua recently announced a new series that has some cameras that use a 4MP 1/1.8" sensor... their minimum illumination specs look better than the 2MP Starlights, so a lot of folks here are really excited for them to start shipping so someone can review it. Price-wise, I think Andy (awesome reseller) mentioned that these wouldn't be cheap, so there's also that...

    So are these 4MP coming out Starlight cameras? Are the only Starlight cameras 2MP right now?

    Based on a white paper that someone posted in this thread, it looks like Dahua (international) is creating three Starlight groups. The 2MP Starlights that have been so popular here for the last few years seem to mostly fall under Enhanced Starlight Technology. The new 4MP models coming out look like they're going to fall under Staright+, so they should do even better than the 2MP Starlights.

    Do we have any indication on timing?

    Read the white paper, time wise Andy appears to think he may have a unit to test within a month or so. We are building a new house and the Starlight + series could be the ticket but too soon to say. Either way going with 10 or 12 cameras.

    Based on @EMPIRETECANDY's post from earlier this morning (here), it looks like he might be able to get a test unit as early as next week. Still doesn't answer the question about when they'll be available for general ordering (or how much they'll cost), but at least hopefully we can see video samples soon!

    Question:
    So the IPC-HDW5442TM-AS-LED with 1/1.8” chip (0.0016Lux/F1.6 ( Color,1/3s,30IRE) with a F1.6 lens is better than a IPC-HDBW4239R-ASE with a 1/2.8” chip with a F1.0 lens (0.006Lux/F1.0 ( Color,1/30s,30IRE)

    It seems to use internal leds, is that than making it 4 times more light sensotive than the camera with a much better lens ?

    F1.0 captures 6 times the light compared to F1.6 if i understand it correctly.

    IIRC, I think the shutter speeds need to be the same when comparing the Lux values:

    0.015Lux/F1.6 ( Color,1/30s,30IRE) -- 5542
    0.006Lux/F1.0 ( Color,1/30s,30IRE) -- 4239

    In that case, the 4239 with bigger lens seems to have better light sensitivity?

    Still learning this, so if I'm off hopefully someone will correct me!

    Difficult to say as the lens on the 4239 is faster f1 compared to f1.6. So how much is due to the sensor and how much the bigger lens is debatable.

    quick question, what's the latest firmware for the 49925? I'm on 04-04-18...have they updated as far as the 5231's to include ability to login to the cam using Chrome and no plugins now?

    Thanks

    I've a 59225 and nope.
    In fact I'm dealing with issues in the latest firmware with the ptz and ivs function causing freezing

    Any chance with all the newer 4MP cameras being released there could be a sticky for them referencing them, much like this one? Would be extremely helpful. I've found this thread to be immensely useful as a resource & go to point for 2mp cameras.

    Also keen to see 5231 knocked out of top position :lol:.
