Sounds like PoE is the way to go. Another option might be to get a webcam that doesn't operate on wifi at all (maybe some other unregulated band which is tougher to block and more importantly, tougher to recognize)

Good luck with the other radio band stuff. PoE is likely easier to find and more reliable. Most WiFi based security cameras already struggle to function decently on WiFi.

You also get cameras that take micro-SD cards and can write video to that as well as streaming it.

  This should be the product people want. I'm betting that the price difference (percentage wise) is low when purchasing a camera. I can't help but think that finding out if the camera is recording to a card will lead to home invasions to get the physical media it writes to as well. Essentially, a cat and mouse game with more and more higher stakes for the thieves and their innocent targets.

    It's trivial to open most door locks. One mitigation is to secure the physical camera, e.g. Axis P1204 can separate the camera lens by 25 feet from the camera with SD card, which can be located inside a locked enclosure/safe/room.

    That’s the magic of Eufy (the Anker brand for this). The cameras run on a separate wireless network and save to an SD card in the base station. You can also do RTSP streams.

      The connection between base station and camera is vulnerable to jamming attacks.

PoE is definitely the way to go if you can. Aside from immunity to radio signal jamming, there's no worrying about batteries/charging or ugly wall warts. You can also power your PoE switch from a UPS to survive power outages. It's also vendor agnostic and fairly future proof. What I mean is while you might have lock-in with cameras/NVR today, you aren't locked in forever; worst case is you may be forced to replace everything but the wiring, but that's by far the hardest part to do in a finished house. The Cat5/6/7 will be useful for the foreseeable future.

  I agree, but I’m having a fun time getting PoE switches that network security will sign off on at work, they are quite pricey. Just a note from the other side, wall wart is 5$ poe is like 40$ a port

    What about Netgear? (I excluded TP-Link for security though it's cheap)
    - MarkMarine 4y ago
      This is for work so the only things that qualify are more enterprise type hardware. I have a MicroTik for my home PoE and it works quite well and it's not pricey.

    Using a regular switch and using a POE injector just before the run to the camera is an option. It's about $15 to get the injector. It's not as elegant as a POE switch though.

Most of the spectrum is cellular. The reason we have wifi at all is because 2.4Ghz is the frequency of water and rain heavily disrupts it. Microwave ovens also work on 2.4Ghz, because they are dumping energy into the water molecules and making them spin.

The problem isn't the power, it's the ethernet. Most homes are already wired for a doorbell with a single wire pair to the doorbell switch and then to the bell. So you'd have to pull an ethernet cable to the door. I just installed an Amcrest doorbell which took me like 10 minutes. I'm using it with Scrypted to connect it to HomeKit. I didn't install it for security reasons. My old doorbell switch was broken and I figured as long as I needed to replace it, it would be nice to see what the heck my dog is constantly barking about. If I wanted something for security reasons, I'd indeed use a PoE camera, but it wouldn't be a doorbell cam. There's very few PoE doorbell cameras in any case and they are quite a bit more expensive. And pulling an ethernet cable to the doorbell switch location would be non-trivial.

  There’s existing two wire Ethernet PoE converters that get you 60Mb and power over a doorbell wire. This technology could just come built into these cameras which would be the responsible thing to do.

    That may be slightly better, but you still need to pull a connection to the chime. In my case, it wouldn’t be all that much easier to get there vs going straight to the door.

    I looked into those and couldn’t find anything suitable. This is a pretty big box: https://www.doorbird.com/downloads/datasheet_a1071_it.pd https://www.doorbird.com/downloads/datasheet_a1071_it.pd It’s expensive, not weatherproof, and hard to order. Same for the one made by 2N. These both recycle old DSL technology I believe. How difficult it is to install also depends on how your doorbell circuit is wired. Mine goes from a transformer in my basement to a switch on my door and from there to two chimes with a junction hidden somewhere. For these converters to work you need a straight run end to end.

  >And pulling an ethernet cable to the doorbell switch location would be non-trivial. The tedium/difficulty/expense of running cabling through walls and crawl spaces is something a lot of tech people seem to take for granted. Wireless is convenient(ish), particularly compared to the aforementioned, so most people are naturally going to gravitate towards it if that serves purpose. Also, ethernet cabling available right at the front door is a security concern in itself. You need to be knowledgable of networking and have appropriate networking hardware to properly secure it against physical attacks.
