Review-Dahua IPC-HDBW4231F-E2-M Dual Starlight Cam

[pozzello]

tough crowd! yes, need to adjust that a bit better. didn't have good lighting when i first set it...
point is I'll be able to replace single cams with these to get overview and detail/choke-point views with better WAF (less visible units on the house)

Where did you get the replacement lenses? I would love to replace a 2.8mm for a 6mm in mine.

 

[pozzello]

that big auction site. eg: Surveillance CCTV 3.6mm 6mm 8mm 12mm 16mm CS Mini Lens Fixed IRIS Camera | eBay

i emailed them before buying and they assured me their lenses are good for IR-equiped cams, as the focusing can vary for IR vs visible light.
Lenses good for both are sort of a compromise between the two, not perfect for either, but not worse for one or the other...

Very good !
i have purchased one of this camera will try with 4 and 12 mm lens

obviously, opening the cam to swap lenses will void your warranty, so keep that in mind...

Anyone know why I see different conditions options on the two cameras?

Backlight is missing from the 2nd camera.

 

[pozzello]

odd. mine does that too, hides the 'backlight' settings page for channel #2...

the pfb203w mounted to the pfa151 will require some minor modifications.
You will have to drill and tap to mount.

Andy, is the missing backlight adjustment something you can inquire about?

Thanks,
Roger

It's always been an issue that way. I asked @EMPIRETECANDY to check with Dahua in June in post #85 of this thread. I haven't heard a fix or an update on that yet.

This model seems have a newer firmware now, tomorrow i will post here.

 

[pozzello]

is it tomorrow yet? hoping new firmware may fix a thing or two... for one thing, I can't get the plugin to work in IE at all on win10 for this camera. Firefox has no issues, but IE just no likie...
keep ssaying i need to install it even though i've done it like 12 times... no issues with the plugin for the2231, just this cam (the dual 4231). you'd think they could us ethe same plugin, but apparently not...

Try the 32bit version of Pale Moon browser.

Thank you for remembering

Is is possible to view both cameras over one feed, split screen style? I'm trying to conserve license count.

I dont believe this is possible...however, your vms may treat is a as single camera anyway...for example, milestone treats an NVR with 8ch as 1 camera and this is used by many to save on licensing costs. What vms are you using?

Synology. Licenses are not that expensive so I can make it work. Another concern I had was wasting too much live view real estate on the monitor.

@EMPIRETECANDY Any updates on the firmware you mentioned a few posts back?

Thanks

A note regarding swapping lenses for longer ones on this dual cam (2231). As LooneyTunes pointed out in my post above, the focus was off on the 12mm eyeball that i converted.
Turns out I had it perfect BEFORE putting the glass dome back on, and the dome messes with the focus. This apparently only affects longer lenses, as the 4mm
doesn't exhibit the same problem (and yes, I cleaned off the domes real well both inside and out.) So focusing with a longer lens is a bit of a trial-n-error p.i.t.a:
adjust, replace dome, remove dome, adjust some more, replace dome to check again, etc... Be forewarned, if you intend to put a longer lens in one of these...
