    New Firmware for IPC-HX5X3X-Rhea_MultiLang_PN_Stream3_V2.800.0000013.0.R.191202.zip

    This is why I'm always reluctant to upgrade w/o good reason. Since there seems to be ZERO information forthcoming as to why this upgrade is necessary or beneficial, I'll forgo the exercise.

    Which ethernet cable would be best ?

    You do understand that for lightning to destroy your electronics, possibly at both ends, it doesn't have to hit the cable directly, right? It just has to strike "near enough." ("Near enough" is highly variable, so I cannot put a number on it.) The longer and higher the "antenna" you're...

    Which ethernet cable would be best ?

    True. I wouldn't, because I don't like a lot of spare cable hanging around. Just the length needed + adequate service loop. I'm a bit of a neat freak where cabling is concerned :) My bigger issue with the airborne run is the lightning hazard. That's going to be a big ol' long antenna just...

    Which ethernet cable would be best ?

    By "Loco" you mean a wireless back-haul using purpose-built hardware, and I of course agree, but still he'll probably need to learn to fabricate cables.

    Which ethernet cable would be best ?

    Not to worry. It's not a dumb question. Common residential outlets have been equipped with grounding connections here in the U.S. since the mid-to-late 60's. Different plug, voltage, and frequency, but same result. That's why. To give the energy somewhere to go other than your house wiring...

    What to do about this gutter on a conduit run?

    This may seem counter-intuitive, but cabling in the ground is as susceptible to lightning damage as is airborne cable. Many a well pump has been lost to nearby lightning strikes. See @sebastiantombs' comments in the "which Ethernet cable" thread, re: STP cable installation. I've never done...

    What to do about this gutter on a conduit run?

    This is why it pays to research, research, research, then ask questions, first ;) The bandwidth demands for video surveillance cameras isn't particularly high, so I doubt you'll have problems.

    What to do about this gutter on a conduit run?

    Tis true. I actually saw this, once. Very close-by lightning strike. So close I heard the sizzle. Saw a big spark jump from the aluminium sliding door in the door wall to the frame. Several bits of electronics in the home theater system shut down, too. (Luckily there was no immediate damage.)

    What to do about this gutter on a conduit run?

    DO NOT run UTP cable in metallic conduit. If you absolutely must use conduit, use PVC. A little light physics lesson: Whenever an electrical charge is applied to wire a magnetic field is generated. Yes: Even in very low-voltage scenarios. As the electric field changes, so does the magnetic...

    New Firmware for IPC-HX5X3X-Rhea_MultiLang_PN_Stream3_V2.800.0000013.0.R.191202.zip

    What I'm wondering is just what "security vulnerabilities" this update addresses and what, if any, other bugs, enhancements, etc. it addresses? There's a note in the OP reading "please check the Release Note," but nowhere any reference to where said release notes may be found. My cams all talk...

    Which ethernet cable would be best ?

    Silly me, but I thought you simply terminated them with the appropriate connectors and plugged 'em into the switches. (Like I wrote, earlier, I've no experience with STP wiring.) 6 ga. would be kind of large, ISTM. Most definitely. Here's another thought, but it might be kind of expensive...

    Which ethernet cable would be best ?

    Actually, "aircraft grade aluminium" is a real thing, though what it means is somewhat variable. It just means a class of aluminium alloys suitable to use in demanding applications--such as aircraft :) Then there's "tool plate," some of which I recently purchased for a particular application...

    Which ethernet cable would be best ?

    Luck of the draw, I guess :) Seriously: I understand being reluctant to deal with a company you feel has done you wrong. BTDT GTTS. In fact I switched from Ubiquiti APs for client connectivity to EnGenius because I had a bad experience with Ubiquiti's management software. But Ubiquiti...

    Which ethernet cable would be best ?

    Amplifi HD is a mesh system. A pair of Nanostations would be a dedicated point-to-point solution. That's not even apples and oranges, but more apples and... I dunno... lemons (Personally, I am not a believer in mesh systems. As often as not they seems to induce as many problems as they...

    Which ethernet cable would be best ?

    Answered by @sebastiantombs <shudder> That is about the last way I'd choose to do what you're doing. If you do, you definitely want outdoor-rated STP, IMO. And, even then, I can almost guarantee a nearby lightening strike will result in a Very Bad Day :( (It's "taut," btw, unless your plan...

    Which ethernet cable would be best ?

    Thank you & you're welcome! Simple pair testers are economical. I realize you're in the UK, so probably different tools available, but here's what I use: Klein Tools VDV LAN Scout Jr. Cable Tester Don't go wrapping UTP in aluminium foil or running it in metallic conduit. That's a big no-no...

    Which ethernet cable would be best ?

    You're welcome. Sure: They'll work--until they don't any more ;) Degradation due to environmental exposure isn't an overnight thing. It's a steady progression that's mostly invisible--until it's not. They're already there and working, so I guess you might as well leave them. But don't be...

    Which ethernet cable would be best ?

    My mind's on several other things, right now, but I'll try to do a context switch and come up with a reasonably useful answer for you, @ANTH040. Bottom line: Pretty much any quality Cat 5e or better cable will do for IP cams. Exceptions are if you're going to bury it, run it though plenum...

    The best budget PTZ these days?

    Watching with interest. I, too, would be interested in an "affordable" PTZ camera suitable for outdoor use. My requirements are somewhat more modest than @ip_poe's, and my budget significantly lower. (No more than around $250.) Heck, my Reolink C1 Pro satisfies many of my requirements, but...

    Have you examined the user's manual for the various solutions for recovering/resetting the admin password? I just looked and there are several solutions presented, incl. using a recovery email address and scanning a QR code with a mobile device. Network Video Recorder User’s Manual V4.4.6 (pdf)

    Video: How To Upgrade Amcrest / Lorex to Dahua Firmware And Get All Dahua Features

    I've got an X-Security model XS-IPDM9852ZWH-2 that was gifted to me by one of my brothers in law. It's a European relabel of a Dahua model. But I can't figure out which Dahua model. It seems to be pretty much identical in all respects to my 5231s, but w/o audio. Even the current firmware...

    Is there a Blue Iris equivalent for Linux?

    I looked at ZM briefly. Did not like. (Don't recall why.) Wasn't interested in running MS-Windows. (Do not like.) Wasn't at all interested in a manufacturer-specific NVR. Found out the Synology NAS I was already running had an NVR app called Surveillance Station. Played with it a bit...

    Review - Dahua SD49225XA-HNR 2MP 25x Starlight + IR PTZ AI Camera with Deep IVS & SMD Plus

    (On Auto-Tracking being removed from the model...) That is indeed impressive. Looks like a lot of setup work, though. (Perhaps not so bad once you've done it once or twice.) And y'know what: If the camera had originally been sold w/o AT, and I hadn't seen the problems I've seen reported...

    Review - Dahua SD49225XA-HNR 2MP 25x Starlight + IR PTZ AI Camera with Deep IVS & SMD Plus

    Indeed. It was astonishing Dahua did that. It's even more astonishing some appear to be going along with it as if such behaviour on the part of a manufacturer was perfectly acceptable. And it's too bad. This camera was looking pretty interesting for a bit, there. Over twice as expensive as...

    But you don't see "IPC-4XXXEM-ASE". They're into the Chinese New Year now. I doubt you'll get an answer before about the 1st of February or so.

    Record from camera to NAS

    There ain't no free lunches. I was faced with a similar situation. Had the Synology NAS. Didn't have, and didn't particularly want, an MS-Windows PC upon which to run BI. Didn't care to run any other separate NVR. Particularly any manufacturer-specific NVR. So I opted to use Surveillance...

    New Firmware for IPC-HX5X3X-Rhea_MultiLang_PN_Stream3_V2.800.0000013.0.R.191202.zip

    I don't understand this instruction in Andy's OP: Does this mean "set the camera to defaults," as in Setting -> System -> Default -> Default, described as "Other configurations will be recovered to default except network IP address, user management and so on."?
