Review: Amcrest UltraHD 2K IP3M-941W

I bought a Amcrest UltraHD 2K (3MP/2304TVL) WiFi Video Security IP Camera with Pan/Tilt, Dual Band 5ghz/2.4ghz, Two-Way Audio, 3-Megapixel @ 20FPS, Wide 90° Viewing Angle and Night Vision IP3M-941W (White) from Amazon. I should note the first one I received did not work. The second one did but took some messing with to get working with Blue Iris

The video quality of the Amcrest IP3M-941W is the same as the 2K Amcrest IP3M-943W cam. In other words about what you would expect from a 1080p cam just more of it. The normal Amazon price is $150 but it drops to $130 on occasion. The main extras you get for an extra $20 over the IP3M-943W are:

  • Pan/Tilt
  • Audio input
  • 5 GHz WiFi

The down sides:

  • Indoor only

Depends on the need:

  • The view is a little less wide with a 4 mm lens instead of the 2.8 mm the IP3M-943W has. Only 90 degrees instead of 100. But that is still wider than the 70 degrees of many cameras.
  • The 4 mm lens is a F 2.2 and the 2.8 is a F 2.0 so there will be a slight difference in depth of field but not enough I noticed it.
Bottom line:
If you need wide angle and pan/tilt or local recording it might be worth the extra money. If you do not need pan/tilt (with 90 deg view you probably do not), before you buy though check Hikvision. One of their models will probably do what you need for a lot less. And if you are really worried about security their dome versions can be bolted to the ceiling to really make it tough for thieves.

Yeah the place is usually a mess with multiple projects going and keeping eval boxes to hand for return shipping. Anyway here is the same view with the Amcrest IP3M-941W
So what you get is pretty much wall to wall coverage if you put it in a corner. Plus a clearer picture. Though at up to 3 times the cost. Note you will get better coverage if you mount the cam about half way up the wall so it can look straight out. Though if your main goal is security instead of something like keeping an eye on the pets then you probably want to mount it as high as you can. Note both these cams use 5 volt power supplies so need to be close to an outlet versus 12 volt cams that can usually be on a 200 foot power cord with no problems.

One last point that might make this camera worth the extra money to you. As you can see above, the picture is clearer but you probably do not really get how much till you zoom in. If I zoom in, with the Foscam FI9821W you can barely make out the floor tiles.

But with the Amcrest IP3M-941W you can easily.

Note all the above pics are direct (raw) frame grabs. A quick contrast adjust in something like Photoshop / Premiere will bring up a bit more detail

Inside it looks like this

Again if you look closely you can see the lens is glued in place so no swapping.
