Thanks! And thanks to Andy as well at Empire for his personal reply!

I have multiples of the old (first) version of this camera (IPC-HDW5231R-Z) that I purchased from Andy in 2016/2017. What is the last stable version of the firmware that it can/should run? The last one I found was DH_IPC-HX5X3X-Rhea_Eng_P_Stream3_V2.460.0000.7.R.20170306 Does that sound right?

I watched this flashing image a little too long. I think the strobe effect caused a seizure. I ended up in the hospital. Happy New Year ;)

I just wanted to add that I am in receipt of one of the new "S2" versions of this model (the model number on the camera includes S2 at the end). The only difference I can detect (at least in the camera I received) is the introduction of an audible "clicking" sound when zooming in and out. The...

This is a practice that really does piss me off. Not only do some sellers mark items as shipped (when they have NOT shipped) they also provide a phony tracking number. When or if it does ship, you have to hope the seller updates the tracking info with a REAL number you can track. Andy has...

Personally, I wish PayPal were an option across the AliExpress site (only some sellers accept it and it is not integrated into the AliExpress payment page.) PayPal would be my payment preference.

This is all an effort by AliPay (the payment processor for AliExpress) to insure international transactions are not later said by the the buyer to be fraud /unordered and then claim the item was never received. I have received many shipments by ePacket and DHL and no signature was ever...

Agree with bp2008. And I would add, the significant savings over buying domestic more than makes up for the risk, IMO.

Thanks Nayr.. always the reliable source of accurate info.

Andy, how are the "s2 ones" different from the prior release?

Hmmm.. looks like there may be a new software/driver version of this cam? S2? IPC-HDW5231R-Z/S2 Free Shipping DAHUA Security IP Camera cctv 2MP WDR IR Eyeball Network Camera with POE IP67 Without Logo IPC HDW5231R Z/S2 on Aliexpress.com | Alibaba Group

Maybe I'll get one of each..;)

Interesting. So which should deliver best low light performance? I would imagine Exmor R. But the larger aperture of the 8232 could also be helpful?

Anyone able to confirm which sensor is used in this cam? Is it Emor, Exmor R or something else? Dahua does not seem to say: IPC-HFW8232E-Z Dahua Wiki indicates Exmor INT/IPCamera/IPC HFW8232E Z - Dahua Wiki I'm deciding between this and the IPC-HFW8231E-Z IPC-HFW8231E-Z Obviously...

You are so right. Perhaps the FDIC should require banks to have better than crap res cams if they want to continue to be insured?

Just order it here. Same seller, different name. DAHUA 2.7mm ~12mm motorized lens 2MP WDR IR Eyeball Network Camera IPC HDW5231R Z ,free DHL shipping-in Surveillance Cameras from Security & Protection on Aliexpress.com | Alibaba Group

Did the seller say that all of the PAL offerings of this cam come without POE? Or was it just the model with WiFi they substituted without permission? I don't have a problem with a PAL cam instead of NTSC since either will work fine. The lack of POE issue is more concerning. In any case...

I have multiple cams on order right now. All varifocal. A few are PTZ. Only 1 fixed. I am far too OCD for "set it and forget it" cam installs. I'd be up on a ladder swapping cams at 10 PM if the FOV just "didn't look right." Then I'd probably swap it back to the original cam the very next...

Did you get to test this model with the Ambarella chip? How is the image quality?

Nayr, which PoE splitter are you using?

Nayr.. man.. you crack me up!!!

I don't have an exterior siren as part of my home alarm. I do have 115dB interior sirens on each level of my home. And I did something extra. I installed two additional 115dB sirens and mounted them inside the ventilation returns to my HVAC fan-forced air system. First, this stops someone...

I've also decided to order and test the new Dahua bullet camera that supposedly sports an Exmor CMOS sensor. It's IPC-HFW5431E-Z http://s.click.aliexpress.com/e/HCgyFU8 I want to compare this to the older IPC-HFW5421E-Z that's on my list above. It does NOT appear to have an Exmor CMOS...

Since this one (DH-SD22204T-GN) apparently has no built in IR, I believe nayr had mentioned that some external IR floods or visible light can supplement this cam. I'll probably test with and without external lights. Thanks!

All great tips and very useful. I shall incorporate all of this. Thanks!

A shootout sounds good. I'm thinking the fair way to do it would be to ensure absoulute consistency. An apples to apples approach, if you will. My initial thoughts: All cams would shoot the same scene, same daylight test, same night test, at the same settings. And it could certainly be...

HDW5231R does look promising. Great low light color spec, etc. The seller in the link I posted said it should ship out in about 2 weeks. So I bet you will get yours before I do (lucky guy!) I ordered all of those other cams, too. (I guess I have a thing for vari-focal motorized cams...

Interested if anyone would share personal experience or general knowledge/impressions of any of these cameras. I'm most interested in your thoughts regarding image quality (day/night), reliability, application uses, etc. I intend to personally test some or all of these prior to deciding if...

Just as Nayr so wisely points out, it varies.. a lot. Example: Here in MA, not legal to record audio unless all parties being recorded are aware and give consent (direct or implied).

Somewhat related I guess, and kind of funny. Years ago in Massachusetts I stopped to help a woman. Her car had broken down on a highway ramp. She was in a pretty bad spot, so I pulled up right behind her car. I was driving a blue/gray crown vic that had been passed down to me. As I was...
