    AHD cameras w/ Blue Iris?

    Sorry for resurrecting an old thread, but I just got lost trying to figure out how to stream from a DVR to Blue Iris. The thing is, I have never used a DVR (PCs only), and don't have one in front of me now, so don't know where to start. Apparently, a DVR can be connected to a PC by a cable, but...

    Endoscopes - what exactly is the problem?

    Hello. I have seen somewhere on this board that endoscopes are unusable for video surveillance purposes because of their F distance. Could someone please clarify how exactly the F will affect what I see through an endoscope pointed into a room? Thanks.

    Dahua: form factor vs price differential

    Actually, this one https://www.dahuasecurity.com/products/productDetail/21407 does seem to not require a base unit. At least, it doesn't say so on the page. Or I should assume that all such lenses need a base for some underlying technical reason? I do understand, a smaller unit (or one w/o a...

    Dahua: form factor vs price differential

    Oh, is it just the question of square vs round, then. It's crazy, but the pictures somehow create a totally different impression until you look at the specs. Same size, indeed. Sorry.

    Dahua: form factor vs price differential

    Yes, I overlooked that - my apologies. The question then becomes: why is the former lens unit so much bigger vs the latter? If both require the main box, why would one pick the bigger one?

    Dahua: form factor vs price differential

    Hello everyone. I'm looking at these two: IPC-HUM8431-L4 and IPC-HUM8431-L1 Am I right in thinking that while the latter requires a base (E1), the former is self-sufficient and can be connected to an NVR directly? The latter is roughly $120 more expensive vs. the former - is that the price of...

    AHD cameras w/ Blue Iris?

    Hello everyone. I've been reading about AHD as a [slightly better] alternative to regular analog cams. I do understand, IP cams deliver better quality, but I'm limited to analog at this point. It says on the web that AHD is compatible with some DVRs, but not the others. However, AFAIK Blue Iris...

    PoE optional?

    Sure, 'sensor'. Speaking of the relative importance of different components, I just need the camera to send a stream to Blue Iris - should I worry about anything else but the sensor in this case?

    PoE optional?

    This looks dangerously close to that definition, doesn't it? Shenzhen LWSTFOCUS Store - Small Orders Online Store, Hot Selling and more on Aliexpress.com They claim to put brand-name matrices in some of their models - how important is that factor, in your opinion? Would you rather go for a...

    PoE optional?

    Thanks to everyone. It does look like in my specific case POE is a product version to be specified when ordering. I just thought, "optional POE" was somehow a standard term. But turns out, it can mean anything.

    PoE optional?

    I'm looking at an IP cam where it says in the description "PoE Optional". I don't have much experience with this, so am really at a loss - does that mean "no PoE out of the box"?

    "wifi camera" - IP or not?

    Okay, it took me a while to figure this one out, but every poster above is right. The cam does have an IP address, which is not advertised in the documentation. It's still not a "proper IP cam", since it works only in AP mode with a range of something like a few meters. That feature is...

    "wifi camera" - IP or not?

    Also, to make sure, we're on the same page, I'm not even sure that the ebay item is an IP camera - it is some kind of a "wifi" cam. So, I have no idea whether it can be paired with a regular computer that doesn't have the "app". Would be useful to hear from someone who knows the chipset in question.

    "wifi camera" - IP or not?

    Thank you for the tip off - I'll look it up. I know, it's junk - but I'm looking for a pinhole IP cam, and this is the closest I've found so far.
