i dont see it in the info listed, but does this NVR support POE? if not, whats everyone using with these cameras? (NVR only).

Use a PFB203W for wall mounting. And a PFA137 for ceiling/soffit mounting.
Using ONVIF with a 8 channel Hikvision NVR, I'm sure there would be other NVR options from Dahua with POE. You'd be better off sticking with the same brand NVR if you're using all Dahua cameras.

That's the part # listed for the non Poe version in your link. You need 12vdc to power the camera. Typically a Poe network switch is used to both power the camera and to add it to the network (for Poe powered cameras). Alternatively, the camera can be connected to a router or regular switch and use a 12vdc power supply. The only connection on the non Poe NVR is a single Ethernet cable that connects it to the network.
This appears to be the one in the advert NVR5208/5216/5232-4KS2 | Dahua Technology you want this one with the POE ports NVR5216/5232-16P-4KS2 | Dahua Technology
The 16ch version appears to be out of stock? Aliexpress.com : Buy Dahua 16/32CH 1U 16PoE 4K&H.265 Network Video Recorder NVR5216 16P 4KS2 NVR5232 16P 4KS2 from Reliable video recorder glasses suppliers on Empire Technology Co., Ltd
Thanks to this forum, I purchased two of these camera...just installed one on the back of the house for now...it is zoomed out a little bit for now. I have these connected to my Synology Surveillance Station.
One question: What is the best spot to perform motion detection / alerts...the camera software or Surveillance Station? There seems to be some overlap in capabilities between the two.
We have a lot of deer that come through our backyard, but am mainly concentrating on the patio for alerts.

thanks a lot guys. the 2nd one you listed is the one i;m looking for. Looking for POE so i can just run 1 cat 5/6 cable to the cameras. now i just need to wait for it to come back in stock
This post on another thread may be of interest to some people- I've put up some day time captures comparing the Starlight 2MP 5231 to a current model Hikvision 4MP (note the model I've compared isn't one of their new Ultra Low Light cameras.) DS-2CD2335FWD-I - Hikvision Ultra Low Light 3M camera
Does your camera have IVS? Use that instead of motion detection. Soooo much better! It is built into most of the Dahua Cameras.

I believe they have IVS. I have to read up on that a bit, but curious how alerts from IVS would go to the Surveillance Station software.

Thicker copper wire = less power loss per meter/foot and thus you can have longer PoE cable runs.

I would say the most important cable spec, whichever AWG you decide, is Solid Bare Copper. 24 or 23 gauge hasn't made a bit of difference for three SD59225H-UNI's, which are PTZ's with heaters. If you are running these 5231's, I feel it's even less important. I have tested these cameras, (5231's and 59's) in every conceivable configuration out there. Power brick, POE (802.3af), POE+ (802.3at) without issue. Keep in mind my test run was 103' 6" exactly.
That being said, pure physics would dictate that larger diameter copper will have less voltage loss over distance. My test runs were ~100 feet, and I used Monoprice Cat 6 Super Duper Heavy Duty Watch Out Don't Pull It by Yourself and Drive stuff.
1000FT 23AWG Cat6 500MHz UTP Solid, Riser Rated (CMR), Bulk Ethernet Bare Copper Cable - Orange - Monoprice.com
It was $111 shipped to my door. It has the internal separator and is harder to bend(easier to damage), pull and get through tight spaces. It's about twice as much as well, but for a longer run, for a PTZ that needs the extra wattage, you may want it.
I bought this Ebay Cat5E 24 AWG Solid Bare Copper for $65 to my door.
BLUE BARE COPPER CAT5E 1000FT CAT5 CABLE UTP WIRE SOLID ETHERNET BULK RJ45 LAN | eBay
I haven't noticed a difference between the two. I bought the Cat5e for power to PIR's and microphones, but ended up using the less expensive cable to test the 3 PTZ's.
I would be remiss if I didn't state that I'm using a Microsemi PD Hi POE midspan currently with the SD59. That uses both pair of extra wires (4,5,7 & 8) to get the power to the camera, but again I tested three powered setups for 100' without issue. YMMV.
