Lets just savour the moment, two people who haven't installed hard wired PoE cameras (one openly admits he has no experience) are telling someone who has as recently as yesterday that the timescale suggested is unrealistic for most people. Got to love the internet
Surely this is exactly the point? Most people haven't, so they won't be achieving anything even close to a neat and tidy cabled install in 20 to 30 minutes.
For people who aren't time served, experienced installers, it's clearly not half an hours work - it's either considerably longer (assuming you have appropriate tools to hand) or paying a professional to do it.
Either way is more faff/cost for most people than ordering a couple of wireless cameras from Amazon and charging the batteries a couple of times a year.
No, i'm not time served, nor do I do this professionally, though i've run a fair bit of cable either re-wiring or retro fitting cable for various purposes and was taught from an early age how to do things to the required standard by someone who was old school and time served. As you're comparing fitting a PoE camera and a WiFi camera, for the sake of argument the physical camera install is almost identical, you need a drill, drill bits, safety glasses and potentially a ladder depending on the install location. In addition to that, to install a PoE camera you likely need a bigger drill bit that's longer, a hammer and some cable clips, you can add another £8 for a cheap but adequate cable termination kit, factor that against the number of broken ends you'll accumulate over the years and it's pretty minimal. You keep dismissing me saying 20-30 minutes, I don't know any other way to say this, but it took me less than an hour to run roughly 47m of cable for two drops, you can choose not to believe it if you wish, but without a time machine you'll just have to take my word for it.
This is irrelevant to your original point, most people are not experienced installers. 20-30 mins to install PoE cameras is unrealistic for the vast majority.
Again, you don't need to be an experienced installer, pinning a cable along a mortar corse where it isn't an eye saw isn't really a skill, it's basic common sense (though sadly not a requirement of employment at OR judging by the state the recent re-pull on the property was left in). Heck even my 13y/o daughter can do that, just don't ask her to drill a hole with an SDS drill, she wanders all over the place. If you aren't capable for whatever reason or choose not to, then as said previously fair enough, but suggesting the vast majority of people are incapable of something in a timescale provided by someone who has actually done it when you haven't, surely you can see the irony in that? Lets be honest, the issue isn't 20-30 minutes, it could be 10-20 or 30-40, you just don't want to do it and are happy with what you have, again, nothing wrong with that. I like my cameras to work 24/7 and record everything in high enough resolution so that it's useful even if an event isn't triggered by something that isn't comparable to a webcam, if the power goes down my system still records and I really like my video to be useful if the worst happens, the 4-5mp ColorVu in near pitch black is genuinely a game changer, the 6mp DarkFighter's are a big step up in quality as well. Clearly you're happy with what you have, but no matter how you look at it, it's a compromise, perhaps it works well for you and you'll never be stung by it's shortfalls, but as a security product, i'd rather pay for better kit and know someone walking in with a £5 wifi jammer didn't render the whole thing useless.
Oh and to answer your previous post (in general terms, I don't know your home), cable can usually be run along a carpet edge next to the griper rod without being seen and with minimal disruption, behind UPVC trim to a door, PoE is from the NVR, not usually a need for a PoE switch (unless we're talking really nasty/old kit) and generally the second thing I do on any property I move into or refurb, is run cable top to bottom and to each room, internally or externally (guttering generally, I try and avoid it being on show eg conduit or old internal chimney that ran 3 floors when I put a combi here) it's just common sense and has been since the first flat I had in the late 90's and yes, each cable CCTV camera run should generally be a 20-30 min job unless we're talking removing furniture/flooring/floorboards, but I normally run back to the loft or under the stairs.
