I’ve configured my system to send out email notification when motion is detected. I’m not getting any email notifications. Why?

There are several reasons why email notification upon motion detection might not function as designed. – Make sure that the recorder is correctly configured for IP/internet connectivity. – Make sure that the sending email account is gmail. – Make sure that the sending and receiving email accounts are not the same. – Make sure that the system is actually ‘recording upon motion detection’ and that the Linkage Method is set to Send Email.

Encryption Key Issue/Solution

Hikvision has created an Encryption Key whenever you use the Cloud P2P feature. When you use this feature it will create a Encryption Key for you to use on each Computer and Device that wishes to remotely or locally view the Camera's. This can be very frustrating as for every equipment you would need to type that Encryption Key. Through the Browser you need to head on over to the Configuration Tab. Select the Local Tab. Under Live View Parameters Section, go to where it says "Encryption Key" This is where you type in the Encryption Key that was given to you at the DVR. Re-log back into the unit and you should be able to see the Live View streaming again. NOTE: This Encryption Key can only be found when you are Physically logged into the Unit, because remotely it will not show this for security reasons

Hikvision has changed the way ONVIF protocol is setup in v5.5.0 firmware version. The main reason for this change is to provide better security for the cameras by default. In firmware version v5.5.0 and above ONVIF is disabled by default. Note the user management system in ONVIF is now independent of the user management system on the camera. The following Hikvision document shows how to setup a camera for ONVIF using firmware v5.5.0 and above.

No Video From Analog or HDCVI Camera

1. I connect the camera to the device and there is no video output. If there is no video then test your power supply or try another power supply. Solution: replace the power supply. 2. If there is no video then test your coaxial cable and BNC connections for continuity or try another cable. Solution: replace the coaxial cable with BNC connector. 3. If there is no video then test your device(i.e. recorder) male BNC connectors by switching BNC cable to other channels. If one works and another doesn't then your BNC ports are mis-configured. Solution: Re-configure the port to "Coaxial" in the HDCVI recorder (main menu*>Setting*>Camera*>Channel type). 4. This series device does not support the analog camera of all brands. Please make sure the device supports general standard definition analog camera, HDCVI. Solution: purchase compatible hardware. Back to Top

After I connected to the IP channel, the single window output is OK, but the multiple windowed output is blank

1. In multi window the output is blank. Check if the sub stream of the camera has been enabled or not (Main Menu->Storage->Record). Solution: substream recording was not setup. 2. If the multi window output is blank, then check the sub stream type of the camera is H.264 or not (Main Menu->Remote Device->Encode). Solution: the encoding stream was setup incorrectly. 3. If the multi window output is blank, then check if the device supports camera sub stream resolution or not (such as 960H, D1, HD1 and etc.). Solution: Find compatible hardware. Back to Top

After I connected to the IP channel, there is no video output in the one window or the multiple window mode, but I can see there is bit stream
