IIUC there is no point to trying to find a USB *THREE* port for a mouse
or keyboard, right? USB TWO is plenty. Because so little data is
transmitted.
 
What about a camera?
 
I know it uses a lot more, but even at the highest reolution, is it more
than USB2 can easily transmit?
 
What about a camera whose video will never be showing on a anything
bigger than a 20 or 24" monitor?
 
 
BTW, just for curiosity, do they sell at consumer prices a camera good
enough to show a picture on a movie theatre screen. maybe 10 feet high
by 30 feet wide. Would that be helped by USB3?

If I were going to this I would use Ethernet POE cameras and at least a
4 port POE switch. The cameras could then be 4k or better if you wanted
that much resolution, plus night vision. I would not even consider USB.

Here is an article reviewing some webcams and comparing
to slightly better devices. The $50 webcam at the bottom does
a surprisingly good job, but it is fixed focus and highly unlikely
to serve any purpose except Zoom.

I wanted to get some waterproof/outdoor cameras that plugged into the
PC, or maybe something that connected straight to the PC.
 
But all I see for sale are cameras meant to clip to the monitor, not be
screwed to the wall.
 
Or if they are meant for outside, they are either wifi or they are meant
to go to some sort of separate video recorder.
 
Do they sell what I want?
 
I'm not worried about burglars or porch thieves, I just want to look at
my yard when I'm inside. There is some wildlife that spend time there,
but I have no window on that side of the room I spend a lot of time in,
and even if there wwere I window, I'd have to stand up, leave my work at
my desk, stand on the bed and look down at the yard. I want to be able
to watch on the PC monitor instead. --- If I went outside, most of the
animals would run away
 
I hoped to have 3 cameras**. A real bonus would be if I could do
something like run all 3 into one hub and just run one wire through the
window frame or wall. (Darn, I found what they call a waterproof
enclosure for a 4-port hub, but it's showing just a regular $10 hub and
a box without only one usb jack. By Sabrent but Amazon has no ratings
and no Q&A. I'll keep looking, or make my own?)
 
It it possible to cut the the USB connector off of a cord, slide the
wire through a hole, cut the wire to the desired length, and reattach a
USB conector?
 
**One facing the front, one to the right of that, and one mounted a foot
or two away, around the corner of the house, facing the side yard.

Run the cable through wall, you could cut the usb cable, near the plug, but leave enough to pick the wires to splice.
If you're lucky, and the wires are uniquely colored, it would be just time to strip the ends of each wire, slip a small
shrink tube over one of the ends, solder red to red (or whatever), slide the shrink tube over the splice and heat it.
If your not lucky, you screwed the cable.
 
No idea about the hub.

USB 2, yes. Just 4 wires.
 
 
Most mildly remote cameras run on network, either wifi or ethernet.
Possibly powered ethernet variety. A USB cable has to be very short.

Yes, that's a much better idea that what was floating in my head, buying
a USB plug. Cutting the wire and then splicing it is much simpler and
will look better.
 
>No idea about the hub.
 
I guess I can use a standard $10 hub and buy a plain box, and do all the
assembly and testing in one room before attaching anything outside.
Hmmm. Because the downspout is in the way, I was going to have to make a
box for the camera to stand on. It can hold the waterproof box too. Two
layers of waterproofity.

Many of these are wireless. Maybe one of the following would do for you?

Amazing how much they do with only 4 wires.

The bedroom/office is only 10 feet x 8 feet (from the front wall to the
PC) plus 5 feet up from the desk to the ceiling, plus 2-4 feet for the
camera leads. 25 to 27 feet. I first say what I've been calling
amplifed cables at Monoprice. But I think they are called repeater
cables.
 
https://www.amazon.com/Female-Active-Repeater-Extension-50FT-15M/dp/B0777FDCX7/ref=asc_df_B0777FDCX7/
 
50 feet for $21! (BTW, your English is great, you must be able to
think in English, but does that mean that feet and miles are real things
to you or do you have to convert them to meters?)
 
I think I already have a cable like this, just in case I needed one.
 
(Even though Baltimore suburbs are growing, wildlife seems to be
increasing. There have been coyote sightings closer to downtown than I
live, and a bear sighting only about 5 miles farther out of town. But
mostly it's deer, and conceivably a fox. I should have done this 10
years ago, but it wasn't until people were posting pictures of the
wildlife in their own yard that I got jealous. I'm 75, but if I really
fix up this place with wildlife cameras, I'll never want to leave.

Perhaps a bit more 'spendy' than what you want - but with night vision, no wires, high resolution, pan/tilt/zoom. That it is expensive may be countered by the fact that it is flexible and you might just need 'one' of it.
 
There are multiple similar options.

I'm in Crofton area, we get dear all the time. They eat our hostas all the time. I too think about a motion sensitive
setup with night vision to catch them. Could be a rabit, but one hosta 70 feet away is about 3 ft tall, so kinda
eliminates the rabbits.

Thanks.
 
The 4th one (5 cameras) and the 8th (3 cameras) are the same and the
same price that Amazon has them. I was very excited about them. They
have what is described as a 2-year battery, but one reviewer said that
in the front of his house, with a lot of traffic he has to replace the
batteries every month or two!! I have almost no human traffic and only
occaional animals, and he said in his back yard, he had to replace the
batteries once or twice a year.
 
I know myself. I will do this once or twice, and that will be the end.
And that's assuming I can get to the camera with an 8 foot ladder.
 
(Well, in the back I could mount one just below the window. That would
work well. So maybe I should buy oone at least. the prices are
interesting. Amazon charges 50 for 1, 100 for 2, 150 for 3 (same price
as bestbuy for 3), but then only charges 20 extra for the 4th and 5th,
getting to the same price, 190 for 5**. But Amazon will include a Show
5 monitor for 10 dollars more (They sell alone for 35!) So I thought I'd
have 2 extra cameras for when some broke, and I was all excited until I
read about replacing the batteries.
 
-- Aha, Bestbuy has 3 cameras with the Show 5 for only 10 dollars more.
I thought maybe they were dumping an old model, but I think it is the
current model. I still think they are dumping them because a new model
is coming out. I learned my lessen when I bought a PC Jr. I paid 1100
dolars but the list was 100 more, and very soon after I bought mine they
came out with the PC XT, a real computer. (To save the 100, you had to
have 20 or maybe 10 proofs of purchas from Kleenex or Kimberly Clark
products. I had two or three, and as the week was coming to a close, so
I could go shopping on the weekend, I went around the office after 5PM
cutting out proofs of purchase from people's boxes of Kleenex. I didn't
ask permission but I don't think anyone planned to buy a PCJr.
 
**They seemed to have been, or I jumped to the conclusion that was the
Black Friday price, but it has lasted.)
 
That's when I started looking at solar powered, but they are more
expensive, I didn't find many in black (to be unobtrusive on my brown
house), and two of them would be on the north side of the house -- don't
know how much sun they get. (A lot of the cameras are white, and I
think there are a lot of white houses, but also a lot of people want the
camera to be obtrusive, to scare burglars away. We don't get many
burglars here and I have nothing to steal, and for other reasons, I'm
not too worked about burglars.)
 
So then I searched more and posted here.

Posted too soon. They do have wired ones, in black even. (See the
best one below****)
 
And by Ring, which surprises me because I looked at "similar products'
on tha Amazon page, but all the similar products they had were wireless,
which makes sense, but still surprises me since the same brand has
wired. "Brand" is an element of similarity.
 
140 to 260 each. Much more expensive, considereing it doesn't have to
have solar cells or wifi. Ah. It does have wifi. It's wired only because
they have flood lights. No wifi floodlights exist yet. Of course
floodlights will scare away the wildlife.
 
(Plus I did put a motion activated LED floodlight on the side of the
house, and unfortunately it's on all night. I don't think there was any
switch to set it otherwise, and it's 24 feet high. I'd better check with
my neighbor who watches my yard from his balcony if my floodlight,
installed 15 months ago, has scared away the deer. (I already asked him
the light bothered him and he said he liked it.)
 
 
****BUT your page also has SVPRO Outdoor USB 1080p full HD waterproof
night vision WIRED for $54!! In black. This might be perfect.
Didn't find it on Amazon iirc using wired usb camera . But they
have it:
https://www.amazon.com/SVPRO-Outdoor-Waterproof-Surveillance-Android/dp/B07C2RL8PB/ref=sr_1_1
 
Something to be said for a store that sells fewer things, easier to find
what you want.
 
This one has a 5 meter cable, not enough, but only 3 meters short. If
I use 3 cameras. I guess I can shorten the 5-meters to 1 meter.
 
"Android" scared me for a second ubut it's for Windows, Mac, Android and
Linux. Does that mean it doesn't work with iPhones? There are a lot of
things that work with iPhones but not Android. Someone said that was
because iOS is standardized and Android is not.
 
I wish it weren't winter. I think I'm ready to go now, just have to
rent or borrow a ladder. (And maybe lose some weight so I won't wobble
too much on the ladder!)

A camera using Ethernet would be ideal: it connects to your LAN so is
available from any computer. A camera featuring Power over Ethernet
(PoE) would allow use of a single cable. Ethernet allows a maximum
cable length of 100 metres, so far better than any USB connection.
 
You can run Ethernet cables through walls - drill a 6mm hole to poke the
cable through. Then fix a socket to the wall - each side - into which
to terminate the cable, and test the finished connection. Use
professionally made patch cables to connect from the outside socket to
the camera, and from the inside socket to your router or network switch.
That way when you break the barb off the RJ45 connector you simply
replace the patch cable.
 
I aske a similar question here a while back and was recommended:
 
https://reolink.com/gb/product/e1-outdoor/
 
At the time they didn't offer a PoE camera - they might now.

Crofton is about 30 miles from me (right between DC and Annapolis for
the rest of you.)
 
If you can get video of a 3-foot rabbit, you'll be famous.
 
SVPRO is 4 stars on only 53 ratings. with motions sensor, but no
fwiw audio. and no visible spotlights like LaView has, but IR LEDs
 
Almost the same camera at about the smae price is called Ifwater 2, but
only 4 ratings, only 2.5 stars. Unusually low, huh?
 
There is also LaView at four for $110. about half the price of the other
two brands. Also wired. 4.3 stars on 948 ratings. Not convince this
is better than SVPRO, because people's expectations are lower when the
price is lower. (as in most cases they should be.) With audio, now I
have to go back and look if the other has audio, even though the deer
don't say much. Also has motion dectetor, which, optionally it appears,
turns on spotlights at night. Spotlights will give colored night
visiion, but will scare away the animals. Probably can be turned off.
 
I also have to think about motion detection. I guess "AI human
detection" is that. But maybe I could ignore that for now.
 
Can't give actualy links because these are all on the other computer.
 
Can I assume the 50 dollar one is better than the 25 dollar one?
 
 
 
Also Noorio at $130, only in white, only wifi, but instant magnetic
installation. Battery powered, not for me.
 
Also JVC KY-PZ510NBU with autotracking!!! Wired, Only $3799! No
ratings.

I lived in Canada for a bit :-)
 
I can think in English, with some limitations, even dream in English
some times. Easier if at the time I'm staying in Canada. I can not
follow all the conversations on tv or movies, a percent I miss. I need
the help of subtitles to help me with those. I have difficulties with
video conferences, I need to get acquainted with each person accent.
 
Reading and writing are far easier. I read a lot in English, and that
makes a big difference on any language.
 
 
No, feet and miles are not real to me :-p
 
one foot, one inch, that's ok. Multiples, no. Miles, even less. What
miles, nautical, land, British, American?

Wild boars are the only things we see in the outskirts of some cities.
Sometimes they get lost or scared and get further into town. There may
be rabbits.

Yep but it is better not to and use a camera with a Cat5/6 feed instead.

And better to use proper surveillance cameras so it can ping you
when movement happens in a marked section of the screen so you
dont have to have a separate monitor for the cameras so you notice
when wildlife shows up.

Yes, a POE wired camera.

low res, over a wide field, and give a policeman a 3x3 pixel face photo.

You might need an injector, to send power from the house, as
not a lot of cheap home networking gear has POE as an option.
 
Since it is Ethernet, it goes as far as Ethernet goes.
 
That camera can dump to a NAS.
 
And it doesn't have to fill an 18TB drive with "pictures

It has 2GB of RAM inside, which is a hint what is hiding in there.
