More IR options

I've posted before about the U06R 60 degree flood and the U06R2 90 degree floods.  They do a good job and only about ~$20. You still need a power supply though. Recently I came across some models from Tendelux that come with the power supply. Their model similar to the U06R2 is just ~$10 more. They also seem a bit less visible if that matters. I tried 3 models.

First let's start with the small spot, just $20, and some compare shots from an Amcrest IP4M-1026
Tendelux 80ft IR Illuminator | AI4 No Hot Spot Wide Angle Infrared Light for Security Camera (w/Power Adapter)
Shot with the illuminator off
Shot with the illuminator on. Far tree is about 35 feet from illuminator and 38 feet from the camera.
No bad for so a fill spot.

Next the U06R2 equiv
Tendelux 120ft IR Illuminator | BI8 Compact and Powerful 90° Infrared Light for CCTV Security Camera (w/Power Adapter)
I stuck one down in the picnic area to see what was passing through at night setting off the motion sensor. The camera, HikVision DS-2CD2032-I with 12mm lens, is about 50 feet away so its LEDs do not light much. It is mounted about 10 feet or so to the left of the picnic table.
A shot with the new flood off though there are other floods down the path in the distance.

After shot with the trees trimmed back a bit and the new flood on.
From another camera, a Hikvision DS-2CD2035-I, you can see the BI8 shines clear across the area some 60 feet bright enough for this cam to notice about 80 feet away.
The bright spots near the center of the pic are the eyes of raccoons at the water trough.

Then for a fill in I added another U06R2 I had not installed yet about 20 feet down on the fence to the right. The water trough is about 60 feet from the cam and about 40 feet from the U06R2.
U06R2 added
Notice it blows out the area near it more than the Tendelux does.

Lastly I was hoping the larger model would be good for the driveway but oddly not so much despite being billed as a 200 foot illuminator it is really more of a wider angle flood.
Tendelux 200ft Long Range IR Illuminator | BI18 90° LED Outdoor IR Flood Light for Security Camera (w/Power Adapter)
Here are compares from a Amcrest IP8M-2496 watching the south leg of the driveway.
Shot with no flood on.
With the "200 foot" Tendelux  on.
I swapped in a U06R and it looks much better. The distant tree is about 55 feet away.
Here are same shots from the Microseven M7B77-WPSV1 zoomed to the 22mm max. The building is about 300 feet away.

With the "200 foot" Tendelux  on.
With no flood.
With the U06R on.
When I swapped the "200 foot" Tendelux with the U06R I moved the "200 foot" Tendelux to point south. From the feeder cams (an Escam QD900 and Reolink RLC-422W). The Tendelux  could probably stand to be tilted up a bit.
From the Reolink pointed west and the "200 foot" Tendelux on, pointed south
From the Escam and the "200 foot" Tendelux on, pointed south south west
For compare. Note how far to the side it had lit up. Seems more than the stated 90 degrees.
From the Reolink pointed west and the "200 foot" Tendelux off, pointed south
From the Escam and the "200 foot" Tendelux off, pointed south south west
Note in the above Reolink shots the U06R was on. Here is a shot from the Reolink with it off for compare.

Viewing the night sky in color with an Amcrest IP4M-1026, IP4M-1055E, Dahua and HikVision ColorVu

So called Starlight cams seem to be becoming a thing so I thought I'd see what is possible with a camera I already had. You can look at my video Night sky Aug 10th 2019 and Night sky Aug 9th 2019 to see what I'm talking about here. Update: added two Amcrest IP4M-1055E cams to get a 180 view of the southern sky.  Here is a sample sunrise video from the south east cam Sunrise 12/5/2019 at 60X

With a few simple tests the Amcrest IP4M-1026 seemed to have the best low light video and the widest view. Mainly I wanted to try and capture some of the neighborhood's fireworks displays.  My first test with pretty much default settings came out OK with lightning.  It seemed to me it switched to night view earlier than it needed so I played with the options to get the video linked above.

I was surprised how much I could make out by just moonlight. It basically looked like what I would see looking out the window.


Below are the setting I used. You might be able to tweak this a bit further with experimenting but I'm happy with the results.







Though the fireworks capture was pretty much a bust as they were a lot more subdued this year and the few that did make it into were mostly blocked by the trees. Thinking now I'll add another cam to close to double the 118 degree view. Note I also did a test with a GW5747MIC 5MP Optional TWO-Way Audio PoE IP Camera 1.9mm 160° Wide Angle Night Vision Sony Starvis HD 1920P Security Mini Dome 5 Megapixel Built-In Microphone and Micro SD slot, Audio in/out Recording but the view was not only no wider but not as good in low light.

Added video without the Moon to show when it is too dark to even see out you can still see the horizon glow of Austin, the planets, at least 1 star, the bard and trees. Here are compare pics from my cameras that catch bits of the same view all from the same time, 8/21/2019 at 10PM local despite what some of the on screen timestamps say.

Snapshot from RLC-511W across south deck. Note plane from video and above Amcrest snapshot is just above far horizon. 

Snapshot from Reolink RLC-511 (non WiFi) of mid drive. Ton of IR down here so any bits not lit are hard to see.
From Hikvision DS-2CD2035-I overlooking the pool area (not currently up). Note when the moon is up you can usually see the horizon in this view.
Just in case you think the Amcrest is optimized for night, here is a snapshot from high noon.

Other cams I'm looking at for really low light

Note these are based on specs and or videos but I have not tried them yet. The 0.5 lux Amcrest above blows the 0.01Lux GW Security cam away in real life.

Updates

Amcrest

Unfortunately this is what the Amcrest IP4M-1055E cam looking SE looks like. At first I thought it was just the fog we've had the last couple days. Then maybe dirt on the lens but it turned out to be condensation on the inside of the cam. I was planning on swapping one with a Dahua IPC-HDW4631C-A  anyway for a compare. Dahua claims a rating of  0.06Lux/F1.6( Color,1/3s,30IRE) 0.4Lux/F1.6( Color,1/30s,30IRE). Sellers are claiming as low as 0.002.

Dahua

I've received a IPC-HFW4631H-ZSA Without Dahua logo 6MP IP Camera 2.7-13.5mm Motorized Varifocal Lens Optical Zoom I'll be testing soon. It is going for $109 on Newegg and $118 on AmazonI should note I see a lot of people posting that the Dahua international OEMs are knock offs. They are definitely a lot cheaper. The "English" OEM is $180 on Amazon and Dahua labeled version of this cam from B&H is $288
I must say I'm impressed so far. I mainly got it to see how the zoom and autofocus compared but the low light is damn impressive. You can clearly make out Orion in the Dahua shot below while the Amcrest used above can only see a few stars. Sirius is easy to make out in both and Rigel can be dimly seen in the Amcrest shot. Once you know it is there you can sort of make out Orion in the Amcrest but it is fairly clear in the Dahua shot. Note this is about at moon rise.
Orion constellation clearly visible above weather station
The same shot from the Amcrest IP4M-1026
Here at there is about a half moon high in the sky but some clouds have rolled in too.
In this Dahua shot you can see the moon is just a light in the sky though Sirius is still visible.
The same shot from the Amcrest IP4M-1055E looking SE. The moon looks more like a sphere though the ground objects are basically silhouettes.
The same shot from the Amcrest IP4M-1055E looking SW. You can see Sirius and barn roof can be made out a bit better.
It is an overcast day but here is a day compare.
Dahua shot of sun through the clouds and birds in flight

Almost the same shot from the Amcrest IP4M-1055E looking SW
On the flip side though if you are thinking of monitoring your yard in color at night you should look at this video of the Dahua being manually switched from color to night / IR mode to get a feel for if you have enough light to make that viable. I'll be adding more videos to the Dahua playlist.


HikVision ColorVu

It is just amazing. See this post for more.
