Question about Bosch DVR4C1161

2 Answers

Hardware reset? I am a Technician in a company in northern Greece . One of our shops had a CCTV system with a DVR 4C 1161 on it . A few days ago the DVR wouldnt let me in , so i drove there and tried with a monitor . I couldn't logon , the password on the machine was not the one it should be . I unplugged it and moved it here and i cannot do anything because a can't get in the menu without a password . There must be a way to reset the pass to its factory default. Cumstomer support didn't help much , they don't know how its done , or so they say. Thanks for any help ...

ELEC DVR Model PRO-SE-HS2008A'The Following Channel Has No Files: 1,2,3,4,5,6,7,7=8!' appears.

Hello Friend,
I am Nitin Khatri from India. 2 reason for this problem.
1. HDD Status OK but not showing recording due to Date changed to old year,month,day, please check camera date and search recording.
2. HDD Status fail, so you need to do following things:-
Your CCTV DVR HDD is not working or got stuck while recording footage, now you need to reset your HDD.
Note:- As you mentioned you replace Computer HDD into DVR, it means your have installed Normal HDD in CCTV DVR which is a bad idea, your CCTV technician should inform you that time when he installed that normal HDD in DVR. CCTV DVR HDD called Surveillance HDD which RPM rate is higher and can work well for recording footage buy a Western Digital Surveillance HDD and Install into your CCTV DVR for future safety.

My CCTV is showing hacked on the cameras. How do I reset my password

Your CCTV is connected via an Internet connection.
I'll recommend to isolate the network devices from the Internet before continuing.
This is covering only basic steps, I recommend to get the instruction manual for the CCTV and read it.
  1. Enter the administration section of the CCTV recorder/DCR/NVR by entering your admin account name and password.
  2. Go to the admin setup of the CCTV. Search for overlay and verify if the hacker inserted text on the overlay feature, if you don't use overlay, disable it.
  3. Then check each camera name tags in the admin section. Change the text if it was hacked.
  4. Change the password for the CCTV DVR/NVR/Camera, I bet it was never changed. Write the password down and store it in a safe place.
  5. Last option: If you can't find the place do a factory reset of the DVR/NVR/Camera. (Do make a backup before a factory reset to an external device if possible).
  6. Once the factory reset is done, you will have to reconfigure the recording options for each camera.
  7. Last point after the factory reset, change the admin password.
Are there other devices sharing the Internet connection with the CCTV?
If this answer is YES, then check them for hacker breach.
  1. I'll recommend to increase the security on the Internet Router.
  2. Any device sharing the Internet with the CCTV should be checked for breaches and made secure.
  3. Speak to your ISP and ask for assistance if you have a fixed IP address to your CCTV system. Ask them for advice. Layer 7 routers are more expensive but more secure.
  4. Load all updates for any devices!
Get an IT security expert to assist you with the breach if necessary.
