I have four Zmodo ZM-W0002-4 720P HD Wireless Bullet IP Camera with Night Vision connected to the NVR. They came as part of a kit with NVR: https://www.amazon.com/Zmodo-Wireless-Security-Cameras-System/dp/B01IT8LXS2?ref=ast_p_ep
They shipped with firmware version V188.8.131.52.
After updating to firmware version V184.108.40.206, the date and time stamps are gone from the live video and recordings.
Is there a setting to enable again on the live and recorded video playback?
On the NVR settings, it does show Channel Tme as enabled.
