  If your Night Owl DVR isn't powering up, ensure the power adapter cable is securely connected to both the DVR and the power outlet. If it's still not working, the system may not be receiving enough power. Try these steps: * Make sure the DVR is turned ON (check the LED indicators on the front). * If connected to a power bar or surge protector, bypass it and plug directly into the wall outlet. * Verify the outlet has power by testing it with another device, like a phone charger. * Try a different power outlet.

  If your Night Owl DVR isn't detecting the mouse, it might be due to a loose connection or the system needing a reset. First, ensure the mouse cable is firmly connected to the USB Mouse port on the front panel. If that doesn't work, power off the DVR by disconnecting the power cable, then firmly connect the mouse to the USB Mouse port. Finally, reconnect the power cable to the DC 19V port.

  If your Night Owl Network Hardware system isn't receiving power, start by checking that the cable from the power adapter is securely connected at both ends. Also, ensure the power adapter is properly plugged into the back of the unit. If the cables are secure, but the system still won't power on, make sure the system is actually turned on (look for lit LED indicators). If connected through a power bar or surge protector, try plugging directly into a wall outlet. Verify the outlet has power by testing it with another device, like a phone charger, or try a different outlet.
