Because Hikvision has introduced Secure Activation feature. So you need to activate IP cameras using sadp or IVMS. http://oversea-download.hikvision.com/uploadfile/USA/Secure%20Activation%20Letter%20052915.pdf

Re-install the PSS software.

I contacted samsung, still no reply can someone tell me the procedure to reset Samsung SVR-1645 DVR password?

- I had similar problem, the mistake was not changing the default ip of the camera.

Its doesn't depend on brand. What is the TVL of your Zicom camera? Is you Hikvision DVR recording in D1 or has D1 resolution ? As far as i know will not see much difference, as a local CCTV installer a Demo and see it yourself before buying.

Wish there was generator for hikvision. If i send them the mail with Serial no. and DVR start time, i will get back after 5 hours to 1 day! Is everyone having same problem?

Thank you the problem was solved, it was firmware issue. updating firmware using TFTP fixed the problem.

i got Dahua HDCVI 5108 DVR, it used to work fine, but yesterday the DVR VGA output and Network port not working. I do not know what's the issue, is it hardware or firmware related ?

Hikvision supports only particular models and only Huawei company. Please call you distributor or Hikvision support for the list.(Prama hikvision India Pvt. Ltd.) They will send you a 3g firmware for you DVR. I know about the old DVRs but 7204 HGHI-SH is HDTVI so only hikvision support will have the information. You can try with 3G/4G router with has a USB port for Dongle. It works, i have done many times.

How about other Video out ports ? HDMI ? In Hikvision there is such problem, a malware makes all ports not working, then we got to upgrade the firmware but not sure about this.

If its Dahua or Hikvision there must be sub-stream or Extra-stream. Will give you little less clarity. Also what slows down ? PC browser or Speed ? -If its speed then you got to increase uploading speed near DVR and Downloading speed of your mobile or PC. What speed does it show in speedtest.net ?

Change the DVR HTTP port to 88 or 81. It will fix the problem. Because Router uses 80 port too.

Download TFTP software from Hikvision Website, Change your PC IP to 192.0.0.128. Download the New or Old firmware and copy it to the TFTP server folder. Connect it to DVR using network cable. Power ON the DVR. The DVR should restart after 3 Minutes. Close the TFTP software or disconnect the cable.

Has anyone come across this problem ? when clicked on PTZ in MENU, the DVR restarts. The DVR is 7208 HVI-SH. I had same problem months ago, i fixed it by upgrading new firmware. I am not sure about it.

I work as a Technician joined a company in May 2014, Just-August 2014 I use do follow what others do in my office and did not care about changing DVR password. more than 65 of our DVR where attacked due to using default password, it was solved by upgrading latest firmware and changing password. The DVR stops recording, all I/O ports, even mouse doesn't show the light. all i can see is power led. So from then i always change password, use virtual server or port forwarding instead of DMZ, Change HTTP port, Server port and RTSP port.
