How to fix Error Code 1602 on iVMS-4200

Error code 1602 in Hikvision’s IVMS 4200 Video Management Software indicates a common issue that users face when trying to view live feeds from their Hikvision cameras.

This error occurs when the software is unable to detect any streaming cameras connected to the NVR, thereby preventing the live view from being displayed.

It usually happens if the cameras are hooked up to an external PoE switch (but it can also happen on NVRs with a built-in PoE switch).

The full error message reads: Connecting to the device… Camera is disabled or not connected. Error code iVMS-4200.Video.C.exe[1602].

Usually, the error 1602 shows when the camera is set on incorrect settings in the NVR, if it is turned off due to a power outage, or if the source device such as a PoE switch is off.

In other words, the camera is not sending any signal to the recorder.

How to Fix Error Code 1602 on iVMS-4200

To resolve this error and regain access to your camera feeds, follow these steps:

Check the Camera’s Power Feed

First of all, make sure the IP camera is getting power. If your camera is connected directly to a power source, such as through a power adaptor, make sure the adaptor is functioning correctly.

If you are using a PoE switch or NVR PoE port, verify that the switch is powered on. You can check the lights at the back of the switch, if there’s power they should blink rapidly (or just be on).

If there are no lights, it means that something is wrong with the switch. Also, check the cables to ensure nothing is loose or damaged.

Check the Network Setup

If you’re using a regular NVR (that is, non-PoE), Both your IP camera and NVR should be on the same network.

For example, if your router’s IP address is 192.168.0.1, your NVR’s IP should be within the 192.168.0.XXX range and your IP camera’s IP should also be in the same range.

If somehow, the camera and the NVR are set on different ranges (for example, 192.168.1.XXX and 192.168.0.XXX), the devices can’t “see” each other and no communication will be established.

To check the IP of the NVR, access the unit directly using a mouse and the local monitor, go to the Network tab and you can modify it accordingly.

If you’re not sure what IP to use, enable the DHCP mode and let the router assign an IP to the recorder.

For the IP camera, use the SADP tool to find the camera’s IP address and modify it to match the NVR’s IP range.

If you’re using a PoE NVR, just make sure the unit is set on the DHCP mode, there’s no need to worry about the cameras’ individual IP address (the recorder will sort that out automatically).

Check the IP Address Settings on the NVR

Double-check the IP address (as mentioned above), subnet mask, and gateway of your NVR (and IP cameras as well). These settings can be found on the router’s information, and usually are pretty standard.

An example is shown as below:

• NVR IP Address: 192.168.1.100
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.1.1
• IP Camera IP Address: 192.168.1.110 (no need to set anything if you’re using a PoE NVR).
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.1.1

Re-add the system in iVMS 4200

After verifying and correcting any configuration issues, re-try the iVMS-4200 software to your NVR. See if the cameras show up. Also, you may try to delete the system from the software and re-add it one more time. 

Other things that you may try include: rebooting the PoE switch, rebooting the NVR, restarting the iVMS-4200 software, making sure the unit is updated to the latest firmware, etc.

Conclusion

If you see error code 1602 on a Hikvion camera system, it always means that the cameras are not communicating with the NVR.

This is usually caused by power issues such as the cameras not getting power, defective switches, defective cable run, etc. To fix it, just ensure that the cameras are connected and powered properly.
