Any comment about ?

Thank you.

Actually I have only analog cameras since about 7 years and maybee I will upgrade to a Dahua XVR and buy HDCVI Cameras to use with my existing installation cables.

Which Dahua  XVR  16 channels  can replace my old Dahua DVR0804HF-U   ?   (I'd like to have possibility to add IP camera and also PTZ in the future.)

What will be a good deal ?  

yes sure, I don't whant to buy another unit for the moment.

Maybee, later I can move to a XVR, but for the moment it's not my priority.

ok.  Many many Thanks ! 

Have a nice week-end.

Best regards

Hi

thanks for quick reply.

Yes, I'm using it since many years ago and this unit working very well.

Now, I'd like to change my old Cameras because it's 420 TVL...   

I'm not a "King" on CCTV System...   I try to add the better analog Camera and not sure which one will be the good one because I can find I lot of possibility (for example on Ebay) but specification from seller are often Comic I think...

What's the maximum Resolution compatible with this DVR on Analog input ?    700 TVL ?    800 TVL ?    1000 TVL  ?     I fund 2 Mp Camera but on CCTV Analog it's not possible 2 Mp or ??

Many thanks for help.

Hi,

Is it possible to use a Dahua SD22204T-GN IP Camera on a DVR0804HF-U ?

Or this Camera is only a stand alone Camera ?

Is it possible to connect on the DVR with dDMSS Lite and use PTZ command for this IP Camera ?

Thanks for your help.

Hi,

I have Audio Problems with my Dahua DVR:

I tried to add an external microphone with the CAM1 on my Dahua DVR.

I undersand that 4 RCA input on back panel are for Channel 1 to 4 and for 5 to 8 (or to 16) the connection is thru DB25 connector.

I try to check the box "Audio/Video" on the "System Config, Encode"" for the Channel 1. (This box is unchecked for all other channels)

I can't hear any audio on the "Channel 1" RCA !

Just a small sound on Channel 4 RCA connector !

I tried to connect the MIC to RCA 1 to 4 and I can only listening to a small audio sound when the MIC is on the RCA channel 4 attached !

The mic is a small "Surveillance RCA CCTV Mic Microphone Sound Monitor CCTV Sound pick-up Camera " like this one:

My questions:

- Are this sort of microphone a joke or usable to hear audio on DVR ?

- If I check the channel 1 "Audio/Video" box on the DVR, I can only hear the microphone sound attached on the channel 1 RCA connector ? (I f I check the Channel 2 is only RCA Channel 2, etc.)

- Where can I find pinout for this DB25 connector. Anybody have this pinout ?? (nothing on the manual)

Many thanks for your help.

Have the same unit Label on bottom DVR16B-57AG V2.0 V100128 - Flashed to new SW/FW @ Q-See web site

 

Product Model Number: QSDR16RTCB-500 Discontinued

 

http://www.q-see.com/products/security-product.php?ProductId=204 Firmware 100724 Download

 

16 Channel H.264 Network DVR with Real Time CIF Recording and mobile phone surveillance and 500GB Hard Drive

 

Also D/L'ed the latest standalone viewer / Phone Viewer / Multi user viewer under the software section tab, all work great. The product could be much better but didn't shell out the $15K plus for a Pelco

 

Was your DVR a Q-See to begin with or a None Branded one like mine? The only reason why I'm asking that is because yours had the v100128 which is listed on the Q-See Support Site but mine is v100806 and I don't see that in the list

Hi !

Mine is V1.0-V091118. What is the most recent ??

With my DVR, I can't view with Iphone and also direct with my PC. Hope this firmware corect this bug ??

regards.

Hi.

I'm PAL, but all DVR are NTSC/PAL switchable no ??
