Hi Angela, 

In situations where all cameras drop off at the same time it usually leads to a power issue. What kind of cameras are we talking about, Analog, HDCVI, or IP? Check the power supply, and possibly power one camera with an external 12v power supply to see if it fixes your issue! 

Thank You! Please let me know how this works out for you!

So you must have either analog or CVI, those cameras are plug and play, very little to no configuring necessary! If you could check th power supply and make sure it didn’t go bad that would be the best place to start! Let e know what you figure out!

What did not work?  Can you verify that your power supply is working?  You may need to take one camera down and try it at the DVR with a short cable and an individual power supply.  Please provide your order number so we can find your information.  Thank you!

Hello HL, 

I am not sure of the exact resolution here for the previous customer, however the same steps apply to you. In situations where all cameras drop off at the same time it usually leads to a power issue.

Having the same issue.  Cameras went out.  Just put in new power supply for the cameras, supply plus the splitter to the four cameras.  Works for about 1/2 hour then goes black again

Hello Bob,

 

It is strange that the cameras turn on for a half hour and then go out. There seems to be something failing here. I would recommend taking a camera down and testing it directly at the recorder with a different power supply and cable. Let us know if that helps. Thanks!

Thanks for the response.  I’m assuming at this point that it is the dvr itself that is the problem, though I can’t figure it out.  I switched out the dvr with my older one and the system seems to be working fine now.

Put the power supply closer to the camera or try a bigger power unit. Double check firewall to ensure that it is not blocking the video stream port for the DVR. Next you have to custom set for the port in the exception list.

Check if the video card drivers are installed properly. (Click start-> My Computer (right click) -> Properties-> hardware Tab->Device Manager-> click Plus + sign next to Display Adapters. If it says “Standard Driver Display Adapter”, nail the issue by finding the Drivers of the Brand and Model of the Video Card. Have the ActiveX controls updated.

 

Check for the camera connection and power, make sure the cabling is okay. Check the settings and reboot the commercial video surveillance systems. Rebooting is one simple option which according to  is the “Golden Rule” in IT troubleshooting, which would flush cache, settings to recalibrate, and connections to self revise. For rebooting, plug off the power supply, wait for few seconds and plug on again.

Also, check for IP address conflicts. Check if your camera is connecting to network using command “ping cameraIPaddress -t” .

Get it updated using latest firmware, and latest client software and reset it to factory default. Good Luck Smile
