Update #2: Loading an older firmware version V3.3.1 for EU/World reset the password and allowed setting a new password. If interested I can write up a detailed account of what I did, for future reference.

Update: It seems that the RS232 port on the back of the NVR actually works and allows access to Uboot. I was able to upgrade the firmware from V3.3.4 to V3.4.5 however the Password did not reset and I am still locked out. I will try to load the new firmware one more time to see if it will reset...

Hikvision DS-7716NI-SP/16 (North American Version) SW: V3.3.4 build 150811 This DVR was picked up from a warehouse closing out. Access to the setup menu is locked (of course). I have two DS-7608NI-E2 units that I already have TTL to USB converter set up on so I am familiar with using TFTP and...

Brilliant! Changing to Tftpd32 worked, allowing a firmware upgrade and resetting the password to allow inputting a new pasword. Thank you

Thanks for the reply. I guess I was not as detailed as I needed to be. First you are correct it is a switch that connects both the PC and the NVR together. Second I am using Tftpd64 by Jounin. I see the geen lights blinking on the switch for both ethernet cables connected to the PC and NVR. I...

Trying to get a DS-7608NI-E2/8P to take a firmware update to get the password reset. Have the TTL-USB connection set up, have the IP address on the laptop set at 192.0.0.128, have the NVR and the laptop connected thruogh a hub, have the TFTP server open and running with the digicap file in the...

Yes I did this on my 2CD3132F-IWS camera with CH serial number. I used the TFTP method (did not work for me thru the web GUI for updating). I tried the CH digicap file first and it did not complete the update for me so I used the EN file. TFTP showed a correct complete update at the end. I did...

Hikvision ASIAN FTP server Post #7

Successfully upgraded a DS-2CD3132F-IW chinese camaera (with hacked English firmware at V5.3.0 and label on camera at V5.3.0) to V5.4.5 using the steps here and the steps for V5.3.0 to v5.2.5 downgrade. Worked exactly as described. The only real problem I had was at some point I couldn't "see"...

If you have older firmware on your NVR there is a keyboard input available for entering alpha characters when you log into your NVR or change your password. Look closely at the login box and there will be a little symbol in one corner that you click to switch to "keyboard". I didn't realize it...

Thank you, your procedure to get the camera recognized by the NVR works exactly as you describe. I actually came to the same conclusion before reading your reply however your step by step explanation is way better than what I could have written up. My best guess is that the new camera...

Further update. If I put the camera on my LAN and use IVMS-4200 client software I can detect and add the camera in IVMS-4200 and see video from the camera. I also see the NVR and all the cameras attached to the NVR, in the IVMS-4200 client. Connecting the camera directly to a PoE port on the NVR...

When the camera is plugged into the PoE port on the NVR it never shows as "connected" and I never see video. If I power the camera with 12 volts and connect to it through a hub with a web browser I get logged in to the camera and can see video, change settings etc. None of the settings you...

Is there any way to get a DS-2CD2135F-IS camera (Chinese hacked English firmware V5.3.3 , Ser # 20151108AACHxxxxxxxxx) to connect to a North American NVR DS-7608NI-E2/8P (firmware V3.3.4)? I was supposed to receive DS-2CD2132F-IS cameras but got these instead. Apart from returning to the seller...
