I think there has been some confusion. My post was primarily an initial follow-up to recent requests for a comparison between my 4mm ColorVu and Varifocal IPC-D5442E-ZE cameras (not old dahua cameras). I’m a bit behind schedule on testing, so I wanted to offer my first impressions. The...

To be honest, I only took the risk of taking my own camera apart, because I didn't fancy sending it back to China - only to face the risk of import charges on a replacement that could potentially have the same issues. I haven't yet done anywhere near enough testing, but comparing the ColorVu...

Hi. I'm currently on the road, but in short - adjusting the lens requires taking the whole camera apart to get at the lens (which its self is locked in place with 3 blobs of glue that you need to remove). I found it easy enough, but it does require a lot of care! Oh, and the camera does have a...

Sorry for the slow reply - I've been away over the holiday season. I will be working with the cameras over the next week or two, so I'll try to put something useful together for everyone.

OK, I've managed to remove the glue and adjusting the focus was quite easy. Everything is now great and equal to the sample image provided by @harb :) Now that's sorted, I'll finally be able to compare it to the Dahua D5442E-ZE. I don't know if anybody else has both of these cameras, but the...

Thank you very much! That’s definitely nothing like the image I have.

Could somebody with this camera please post a couple of full resolution daylight screenshots from this camera? Also, if you have the 4mm version - could you please let me know at what distance objects are at their sharpest? I received a 4mm T2347G-LU from Andy at the end of last week, but...

Fantastic news! Thanks for letting me know :)

Yes, under system/Maintenance (I think), you should find the option to reset everything other than network and passwords etc.

I will add that your second photo (the best sample from the “defective” camera) does not look anything like mine did - mine went straight from the top image to the bottom one. Your middle photo looks like a combination of some WB/exposure/brightness problem, possibly caused by the the relocation...

I had one of these Darkfighter cameras about 4 years ago. I can’t swear that it was the identical model (I have 4A26 in my mind), but it had a similar problem. If i recall correctly, i could zoom out until 2.8mm was displayed on the screen, but then it would continue a fraction further and lose...

Thanks for all your responses!

Yes, I’m certainly struggling. The fact that I’ve found two data sheets, which appear to show the same model numbers but differing face recognition and ANPR features leave me very confused.

The more I look into this, the more confused I get. Could it be that Dahua are marketing the same product with different features in different regions (using the same model names)?... Product 1: NVR-4216-16P-I (Lite-AI Series) This data sheet mentions picture stream recognition (with FD...

Hmm.. Forgive me if this is a dumb observation/comment, but I notice that in contrast to the description on the Dahua International website - the product data sheet on the Dahua US website excludes support for 8 channel picture stream face recognition (requiring FD camera) from the spec of the...

Thanks for taking the time to reply, looney2ns. I really appreciate the feedback (and your earlier review). The fact that @EMPIRETECANDY provided the unit for honest testing is also the reason why I’m trying to buy everything from him. Had the Facial recognition features worked, the 4216 AI...

I’m currently in the middle of preparing an order for some cams from @EMPIRETECANDY. My original plan was to go with Hikvision ColorVu cameras, but the Dahua IPC-D5442E-ZE (pro AI model) looked quite interesting for my front and back door, as it offers a wider viewing angle and lists face image...

I'm glad it fixed the problem. :-)

Hi Tello, I'm glad this one worked for you. Did it also fix the SMB/CIFS issue that you were experiencing a few months back? As for the Chinese language thing - I'm afraid I really don't know. I guess the only option (short of going back to v5.0.2) is to disable the Day overlay. Not...

Hi, I know that a few months have gone by, but just in case you're still interested (or if anyone else out there has one of these cameras)..... CCTV Discover uploaded a new firmware for the 720p & 1080p K20 PTZ cameras. The new firmware is based on v5.2.0 and can be downloaded here...

Please let me know how you get on. I had exactly the same problems with four Hikvision cameras, whereby even the live stream viewed directly from the camera had a stutter. Despite having a reasonable (not perfect - but reasonable) understanding of iFrame settings, shutter speeds, exposure...

This might sound odd, but when you tested Hikvision's IVMS-4200 software - was QNAP Surveillance Station still running and connected to the cameras? If so, can you confirm whether the problem continues in IVMS when you disconnect the NAS from the network? Craig.

OK, here you go. 1) v5.02_140312 (With Chinese Date and Time) >>Download<< 2) Latest full English firmware >>Download<< If you test the English firmware, I'd be grateful if you could post the version and build number. Craig.

I've been in touch with CCTV Discover again and I've also managed to get you the latest Full English firmware too. I don't know if it will be a newer build than the one you have (I haven't tested it yet), but at least you can get back if the other one causes you any problems. I'm uploading...

Update: I have just found the firmware update if you would like to have it. The details are as follows: Firmware Version V5.0.2 build 140312 Encoding Version V4.0 build 131211 This firmware from March will change the date and time to Chinese though, and unfortunately I don't have the original...

Hello again Tello, Following on from our other discussion... don't you need to include something like cifs in the line? For example: Server: //servername/sharename Path: /folder/mountname cifs username=myusername,password=mypassword 0 0. I really wish I could remember how this...

Sorry, I think there might have been an missunderstanding. It was my friend who set his camera up with SMB/CIFS. On my camera these fields are not used - I have everything connected to a Synology Diskstation with Surveillance Station installed. Craig

Oh, I see - I didn't realise that there was a popdown menu on the newer firmwares. I actually have the camera set up at my parents' home, but thankfully I installed teamviewer on their PC yesterday - just in case I needed to go back and check anything else. No, unfortunately the firmware...

Hi, I do have the option to enter NAS server addresses and file paths, but unfortunately I can't specifically confirm whether or not it works with SMB/CIFS. Is your camera lacking the "NAS" tab altogether, or is it that you just can't connect? I will mention that my camera is still based on...
