    5.3.4 - November 22, 2020

    Accepting that it’s probably a RTFM issue, but having installed this new version and then reviewing alerts on my iPad this morning, the duration of alerts videos seems to vary widely. In some cases it goes on way past what I think is the end of the motion but on others it is cropped before the...

    Review-OEM Loryta IPC-T5442T-ZE Varifocal 4mp camera (Dahua)

    OK Andy. Good to know the upgrade is mainly for smart IR. I have no interest in the camera’s AI etc. My interest is in getting the best possible facial images after dark.

    Hi Andy, I finally have a warmer feeling about this latest version. How about posting it so we can all have a dabble if we so wish.

    IPC-HDW5231R-ZE Rhea V2.800.0000016.0.R.200605 Latest new firmware

    Hi Andy A couple of weeks ago and without checking the recent threads posted, I unfortunately got round to updating the FW to version ....16... in one of the two 5231 cameras I bought from you (along with other cameras) back in November 2017. As with other guys, after updating it was OK at...

    Review-OEM Loryta IPC-T5442T-ZE Varifocal 4mp camera (Dahua)

    Did you use the helpful advise to experiment further with your settings Funkyduck? I have to say that I don’t favour a fixed shutter setting. Far better to use Shutter Priority / Customised Range (Dahua). Set to 0 - 8.3ms to correspond with the suggested 1/120 so that the shutter time will...

    HI Funkyduck Many thanks for the post I requested comparing the Hikvision vs the Dahua and yes, as you said, the Hikvision shows more detail. What’s more, the 8MP 1/2.5 Hik is not so much darker than the 4MP 1/1.8 Dahua. Of course, the very knowledgeable forum member Wopi82 did point out...

    Any chance you could post snapshots with IR to show the Hikvision is sharper than Dahua please? I’ll be surprised if it’s down to it being 8MP when it’s dark, but wouldn’t setting the Hik down to 4MP as a comparison test be worth worth doing? I’ll also be interested to see the result of the...

    Mmm... very interesting Funkyduck. So you’re saying that after extensive testing, the Hikvision DS-2CD2385FWD-I is better than the T5442T-ZE? Is this with like-for-like conditions and settings? For example, both in black and white and both in colour with similar lighting? I see in your...

    IPC-T5442T-ZE IPC-T5442TM-AS latest new firmware IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.800.0000000.20.R.200903

    I wonder looney2ns, is that a polite way of saying it’s no different to the previous version? Do we know even know if smart IR actually tries to reduce the IR strength or instead is supposed to dynamically compress the gain to prevent white level clipping?

    Hi CCTVCam and looney2ns - this IPVM tool is fabulous!!! When I tried to use it previously I obviously clicked on member only features and gave up but your brief driving lesson CCTVCam hit the spot. Hope it lets me play with it for free ad infinitum. What a great forum this is!

    I think most (including me) will look for guidance from this forum rather than stumping up a $200 annual subscription, even if it means you will forfeit your refer-a-friend payback. Sorry looney2ns, I hope you don’t black list me!

    Bigredfish, I think the maximum specified distance (I guess in daylight) to identify someone you don’t know for this camera is 23 feet (corresponding to approx 60 pixels per foot). Where is that on your drive? What do you reckon that distance is at night given your settings and lighting. My...

    Common issues with camera image

    Hi bigredfish, I think my words may have been ambiguous - sorry for that! My remarks about shutter speed and motion blur were merely defending the use of a frame rate of 10fps instead of 30fps and not about your other settings. I was trying to point out that regardless of the frame rate, the...

    Common issues with camera image

    Hi aristobrat As I mentioned, I was surprised to see that when I tried h.264 instead of h..265 with the same bitrate setting, the image quality was only slightly worse. Regarding your success with VBR, my guess is that with your scene, the bitrate does not decline very much (mine declines...
