Anyone seen the IP4M-S2112EW-AI Amcrest/Dahua camera in the wild?

[erkme73]

I just receive a promo email from them... Looks compelling for sub-$200.

I like the wide field (2.7mm) and two-way audio for gate use...

The biggest drawback I see is the 1/3" sensor, which is barely suitable for less than 1MP; a 4MP with that sensor size won't be much good at night without supplemental lighting, IMO.

Well, I'll take one for the team. Just ordered.

I think looney2ns will have a review of the EmpireTech version of this ptz later on. Andy posted some pics of this mini ptz before.

Just check my e-mail, I also got an e-mail from Amcrest promoting this camera for $197.99 limited time deal too.

I think that's a different model. No optical zoom...

Yeah, I really just need it to be able to ID people at my gate, and communicate with them. When UPS/FedEx send sub drivers who don't know the gate code (or who struggle reading the instructions on the gate), it'd be nice to give them verbal instructions... First world problems.

I have plenty of coverage with other cameras at night.

ETA: on second though, after researching the sensor size of 1/3 vs. the 1/2.7 that is currently on my other amcrests, I think this would be step backwards. Got cold feet. Pulled the plug. TY.

Ahhh... you're right. And it's 4MP.

Gee, I looked at this on amazon about 2100 CT (an hour after @erkme73 posted the link) and it was $219 !

It showed $219 when I looked at it, but there's a 10% off coupon... that's what gets it down to the advertised price.

It's only 4MP

Being 4MP is not so bad but ideally it should have a sensor no smaller than 1/1.8" as below for decent nighttime performance:

I just got one from Amazon. I installed it yesterday and I have it connected to BlueIris. So far, it's a pretty nice camera for how I'm using it.

Curious how your night performance is. Can you send a couple of captures?

 

[mrbadlans]

I'm actually not using it in "night mode." I've got it installed on top of my house, and it's focused in an area that's several hundred yards away from the camera. I'll see if I can get some night shots, but I'm really not using it for that. Stay tuned.

 

[erkme73]

I'll take what I can get I actually ordered it when it was released, but then got cold feet. I probably will end up buying if the reports continue to come in positive.

I've installed this camera is an industrial parking lot. I own several other, lesser Amcrest cameras and their "human recognition" algorithm is very impressive. So I bought one IP4M-S2112EW-AI expecting the same. Instead, I find that it's non-functional for "humans" and works only like a dumb camera that recognizes any kind of motion. Can anyone else corroborate this? My camera's firmware is dated Jan 30 2023, so it's quite recent.

Thanks for the update. Any word on the picture quality? Especially at night?

Good in daytime, blurred at night in some parts. I'll post a picture. See for yourself. This is at max zoom. Notice the chain link fence. Lighting is from flood lights, not from the camera. I cannot test for efficacy of inboard light emission.

For the $200USD price, that's not bad at all. Unfortunately I have no external (white) lighting at my intended location, so still unsure about whether the IR based night image quality would be a disqualifier. Your image is definitely a good data point, though.
