Looks like i have a day of testing 5x PTZ1A225-HNR-XA, 1 X PTZ1A-HNR-GB, 2X IPC-HFW-5541-EP

Thanks Andy Unfortunately the nature of our business means we often have to make good use of the mozaic masking to reduce the public areas and as the GB does not have that it has limited use for us. I have been lucky and managed to obtain 5 of the XA version after these are gone I am not sure...

Oh well the GB variant has arrived today and straight away i found a show stopper for us with this variant. The XA variant has Mozaic masking but has now been removed on the GB variant. Strangley I have one camera which is an earlier variant on the XA and that does not have mozaic so they...

Yes the downgrades are one of my concerns I have seen that on some other models. I think we will stick with the variant we know as it has been a good solid work horse for us.

We have been using the DH-PTZ1A225-HNR-XA for a few years now with fantastic results. this has far surpassed quality wise many of the other PTZ models we have tried considering its only a 2mp camera. Also night colour images in an area with plenty of ambient light beats any other camera we have...

https://www.oprema.co.uk And I just ordered 2

This is where the camera will be located the current cam there is a Hikvision DS-2DE4425IW-DE or the live image at York ROC Camera No.1, Yorkshire UK - in Partnership with Network Rail | Railcam LIVE

its a trade only supplier based in the UK

One of our suppliers is currently selling the SD8A440-HNF-PA for £350 plus vat. Clearance sale so I guess it is becoming EOL. This seems to be an extremley good price for a smart wiper fittd PTZ. We are aware that it is a beast of a camera having the 1st 4K version of this cam. the wiper is...

Does any electronic equipment last long in this day and age. You would expect Axis cams to have a long life given the price, but we had one wehere the sensor failed after a couple of months granted they replaced it under warranty but it was a long drawn out procedure. We have over a 100 Dahua...

Thanks Wittaj, I should have found that on a search really.

Does anyone know know the procedure to change the lens on these cameras,? I dont want to damage them just trying anything

No the camera never actually fell off a pole i was just saying that due to the weight and size I would not be confident mounting it on anything less than 125mm diameter and preferably much bigger like a telegraph pole. The SD8 is totalover kill for what we do but the location it was intended for...

Actually just remembered we did this last year of the moon, not great but I was pretty pleased the model is DH-SD8A840WA-HNF

I will do over the next few days but the lens needs cleaning first :)

Its only a 2mp camera and been out a while but you might want to take a look at the DH-PTZ1A225-HNR-XA That could look straight up at the sky should you so wish. Additionaly the SD8 series of cameras are very heavy and i certainly would not want to put one on a pole unless it was a substantial...

Thats the box that we have used for our installations. and have managed to use it with the rain hood aswell with no modifications as such.

I have just tested this and managed to trigger the siren but not the lights. On the app click the little arrow symbol under the Mic symbol and then the bell symbol you get a pop up warning about the siren being loud and after clicking OK it then sounds for 10 seconds. Hope this helps. Andrew

Well after intialising my last remaining S2 variant held in stock it would appear that the S2 variant is not equipped with Mosaic masking and the solid masking can no longer do polygons. That kills the further useage of the 49225 family dead in the water for us. I wonder if the 49425 family has...

I did think about rolling back but was not sure if it would work and I can only find the latest firmwares.

Thats a lovely looking model. Unfortunatley its unavailable and also overkill for us as we do not have the bandwidth to run it to its potential. Maybe I should have stated that we can not push out much more than 1080p. Company policy say it has to be purchased from one of our nominated UK based...

Yes we have a number of the first release of this cam but they have never had autotracking on them luckly thats not a feature we use anyway in our use of them. Do you have a recomendation for an alternative model that has reasonably good vision at night without using B&W and infared? There is...

A little gripe. Why do Dahua not have changelog details for new firmwares on the official pages. We have 3 of the S2 variant of the SD49225XA-HNR and having just updated the firmware I now see that that the mozaic masking has been removed and the solid masking no longer allows polygons. this...

Good afternoon. has anyone come across a Dahua camera that is capable of carrying out realtime facial mozaic masking for privacy of subjects in view? I found a page on the Dahua site that discusses this but clicking on the camera models indicated at the bottom of the page there is no mention of...

Here are a couple on our test rig and one once our social media team got a view lol

Hi we have just taken delivery of one of these cameras and using a PF203 bracket, Has anyone found the issue that when mounted in the correct orientation using the PF203 bracket and iusing the 2nd substream in "horizontal stitched" mode the image from the right hand side of the camera appears in...

Did you ever manage to resolve this?

I just thought I would add a bit for any potential UK users that may require audio. We have been using these mics successfully across 50 cameras for over a year now and coupled with a POE splitter and Wind muff the quality is pretty acceptable. Mic -(also have a gain adjustment built in)...

I will probably come back to you with some questions as we switched to Dahua from HIkvision last year (8 years of Hikvision use) as our preferred camera's. I need to learn more about tweaking our existing Dahua cameras to get the best out of them. There are some terms used in this thread that I...

Yes it was the 5A425s we have purchased along with 5 IPC-HFW5541EP-ZEs
