    Two POE Cams Over One Ethernet Cable

    OTOH, a 3 port 100baseT switch is a tiny chip now, and if the cameras only need a few watts each, and teh PoE source can provide more than enough watts for both, then yes, you can do the single PoE cable into two PoE connections using an active cable adapter with a cheap switch chip encapsulated...

    Two POE Cams Over One Ethernet Cable

    normal 10/100baseT connection only uses RJ45 pins 1-2-3-6 (1 and 2 are the orange pair, 3 and 6 are the green pair), pins 4-5 and 7-8 aren't in use. Cat 5/6 cables have all 8 wires, 4 pairs. So the '2nd' POE cable has its orange and green wired to the blue and brown pairs 'main' cable...

    Two POE Cams Over One Ethernet Cable

    My guess is, that adapter just connects two 100baseT 2-pair poe ports over a single 4 pair cat 5/6 wire. It should work, most all cameras are 100baseT only, and even if thjey are gigE, they don't /need/ gigE speeds.

    PoE Switch Suggestion List

    For laughs, I picked up this cheap switch, because the 4 port + uplink POE switch I was using in my home office was out of ports. https://www.amazon.com/gp/product/B099PK5NPG been using it for a few months now, so far so good. case gets just warm, not hot.... its running 88 F in a 70F...

    the tricky part is getting enough light in the distance without washing out and overexposing the foreground.

    More recent IR illuminator recommendations?

    I have a Microlight IR Helios 30 degree spotlight, that works very nicely and is nicely made. I've had it 4 months now, so can't talk about long term reliability yet. the light quality is very good, even 30 degree cone with well defined edges, almost no illumination outside that. its off...

    how can I edit out myself in a video?

    as far as how you crop with ffmpeg, its like this... ffmpeg -i in.mp4 -filter:v "crop=w:h:x:y" out.mp4 where w, h, are the width and height of the output video, and x, y are the upper left corner offset. If your original image is 2520 wide and on your screen, thats 10 inches wide, measure to...

    how can I edit out myself in a video?

    huh, ok. our pumas stay with their mom until they are about a year old and nearly mature size I have a few more camera captures of them around my place here on the midleft coast, as well as lots of bobcats, coyotes, etc.

    how can I edit out myself in a video?

    that looks like a very large house cat to me, not a cougar/puma/mountain lion/panther. this is a young puma, west coast style. local puma tracker folks had just tagged him, and said he was an 85 lb young male. I know the Florida subvariety run a little smaller, but still, they move...

    any PoE cameras that can be configured to FTP/SCP/SFTP/RSYNC a picture to a webserver every 5 minutes w/o needing a NVR or other sort of server? or will I need to do something with a raspberry pi or something for this?

    I wish these PoE cameras had an option to OUTPUT 12V at maybe .25 amp (eg, 3 watts) on its DC power connector so you could use that to power lighting.

    thats what I did with 2 of the 3 emitters on my 30 degree spot. about 6 layers of scotch 'magic' tape proved just enough to provide some fill light on the area where the trailer and car is parked while still throwing a ton of light in the narrow beam aimed at the driveway entrance from the...

    opoops, I missed that its a 940... afaik, that won't work very well with most of our cameras. I used the spot specifically to hit my driveway entrance which is 100+ feet away (I think the road is 160 feet or something). its tricky balancing lights between the foreground and distant, a...

    if yiou have a SD (micro?) card stuck in a camera, you're probably going to have to take the camera apart to extract it, and that quite likely will damage its weather seals.

    they are a little expensive. nicely made, properly weatherproof. to permanently install them outdoors, I would solder splice their pigtail to similar wire for the rest o the run, use marine shrink wrap to seal the wires and the whole thing. I'm looking at IR LED tape, that I can mount in...

    the spotlight had 3 LEDs that were just too bright at the ~100-120 foot range I was shooting for, so I covered 2 of them with 3-4 layers of scotch 'magic' tape to frost them, now 2 of them are floods, and the third is still a spot, this works pretty good. I've actually turned off the IR...

    rack mount equipment is supposed to suck fresh air in the front and blow hot air out the back. but I've seen a bunch of relatively low power 1U network stuff that sucks it in one side and blows it out the other. I did my share of servers, RAT NEST! and a couple years later, I had to...

    Replacement fans for PoE switch...

    one thing you can do with 1U kinda commercial equipment in a SOHO is take the cover off, and mount it on some riser side plates so its now effectively a 3U or 4U, and put a couple low speed large fans aiming down at the board, with cardboard baffles. some plastic screening on both ends to...

    Replacement fans for PoE switch...

    big commercial switches like Brocades are intended for rack mount data center usage, where noise isn't an issue. A fan for a 1U chassis can only be like 25 or 30mm, and for a fan like that to move sufficient air, its going to be noisy

    most any cam will work OK in the daylight, where they really differ is in how good their night vision is. a poor camera might even superficially look ok on a still scene at night, but something moving will be too blurry. and many cheap cameras 'fake' it with very bright IR illuminators, which...
