I got a dahua Cam with a plastic dome (DH-IPC-HDBW2449F-AS-IL).
Example vid with turned off/on IR, LED,, with in various output Power:
Nights I cant turn on IR or LED. It reflects like crazy.
I cleaned the plastic dome, its top condition.
There are bicycles. Are the Bikes reflecting the light back? I thought this was negibile.
Has anyone similiar eyperiences?
I got an site where we installed 12 PoE cams. All fine.
One strand gives me headaches. Connected via active PoE 802.11af switch with 180W which is connected to an 1to2 PoE Extender which powers 2 PoE cctvs.
One of these two Poe cctvs works flawlessly. The other looses network ca. 6x per night for up to 10min-2h. First I thought the whole PoE and network is down, but in the logs I saw that PoE still powered the device, but only got no network.
I even wiresharked it, and there wasnt any connection from NVR to the device during the outages. But the cam still ran standalone via PoE (No gaps in internal sd card recordings)
Why is this happening? Mostly occurs 10pm - 4am in the morning. IT never happens during the day.
During the day the device works fine. PoE and network run smoothly.
How can I identify the issue? I know there is no network during the time, but how can I troubleshoot it?
I already replaced the switch and 2to1 Extender. Same result.
