    Need Help SD8C845FG-HNF Not Communicating

    I just got back in the office this morning, and I want to start by saying a BIG THANK YOU to BigRedFish and Wittaj for all the advice and help. Without you, I would have been lost in trying to figure this out. The camera is working great now, and I will leave it running for a while to make sure...

    Need Help SD8C845FG-HNF Not Communicating

    Thank you, wittaj and BigRedFish, for your input and suggestions. I did a hard reset, and now I'm having trouble connecting to the PTZ. I have tried the following: With the NVR already powered on, I power up the PTZ, which is connected to the mid-span, which is connected to the POE switch...

    Need Help SD8C845FG-HNF Not Communicating

    Interesting issue to say the least. In the closet with the lights on, a solid 5,000 to 7,000 kbps. As I increase the shutter speed from 10 to 100, the kbps roll in the 16,000 to 19,000 range. Then I increase the shutter to 450, and it's nice and bright light daylight, and the camera locks up at...

    Need Help SD8C845FG-HNF Not Communicating

    BigRedFish: I have the camera hanging in a closet from a clothes rack. Everything was going great until I decided to turn it around, facing out the door, where it is bright, and then repowered it a few minutes ago. When I try to view the video via the NVR Web interface, it shows 13,198 kbps...

    Need Help SD8C845FG-HNF Not Communicating

    Pain in the ass on this one is big. Very heavy PTZ, aluminum ladder stretched to the max to 20 feet to get to the mounting location on a tree on the side of a mountain, pulling it up with a rope and hanging/mounting it, life and death for a guy my age. I have the PTZ running here in the office...

    Need Help SD8C845FG-HNF Not Communicating

    Thank you, Wittaj & BigRedFish, for your response and suggestions. As always, you two come through with great questions. I made it back home a little bit ago and brought the PTZ into my office, where the NVR is, along with the inbound fiber optic converters from the different hub locations...

    Need Help SD8C845FG-HNF Not Communicating

    Hello Gentlemen, I need your help with my PTZ Dahua SD8C845FG-HNF. The camera has worked great since I got it new from Andy back in October of 2022, but it has stopped communicating with the NVR. The camera powers up, completes its standard diagnostic testing, and goes to its programmed...

    DH-SD6AL433XA-HNR Tracking Issues

    Agree 100% on the yardsticks, and I've increased my sensitivity on all the cameras as well. They are working great, thank you, Bigredfish, for all your help and for posting your camera settings. Also, thank you, Wittaj, for your reply and advice. Both of you have been tremendous help to this...

    DH-SD6AL433XA-HNR Tracking Issues

    All I can say is WOW! Thank you, Bigredfish, for sharing your camera settings. I copied your settings, and both PTZs are tracking better than when they were new. I'm wondering what the effect of your bitrate of 12288 versus mine at 8192 may have contributed to some of the issues? Thank you again...

    DH-SD6AL433XA-HNR Tracking Issues

    Thank you, gentlemen, for your replies and suggestions. I haven't done a factory reset yet since I'm still trying to diagnose, but interesting results from testing yesterday at sundown. The PTZs had switched to black and white, and both 433 PTZs tracked perfectly. In the B/W mode, while the sun...

    DH-SD6AL433XA-HNR Tracking Issues

    Thank you, Wittaj and Bigredfish, for replying. I did make some adjustments to the image to make it more distinguishable, but I still have some tracking issues. The main problem is that once the target is identified and locked on, within 2 seconds of acquisition, the camera loses the target and...

    DH-SD6AL433XA-HNR Tracking Issues

    I'm checking to see if there may be a firmware upgrade that would correct some recent tracking problems that have arisen on one of our PTZs, DH-SD6AL433XA-HNR. Maybe someone who has the same or a similar PTZ has run into the same issue and has a fix. The PTZ is wandering and losing its target...

    Problem: Dahua Switch is not being recognized by Dahua NVR. I have tried plugging the Dahua PFS4226 switch uplink ethernet cord into the second NVR RJ45 uplink receptacle with no success but when plugging the Dahua switch uplink ethernet cord into the Cisco 110 Series switch the NVR connects to...

    Replaced NVR with new NVR and Cameras say "Failed to find Network Host"

    Thank you for the quick reply Flintstone61. Using the old NVR I was able to get one of the 3 cameras to go back to factory default since none of the 3 cameras allowed me to modify their IP address. The second camera went to factory default but kept its NVR-assigned IP address 10.1.1.x and I...

    Replaced NVR with new NVR and Cameras say "Failed to find Network Host"

    Thank you Mark M and Flintstone61 for your responses and great suggestions. I was able to get 12 out of 15 cameras batched IP change using the Config Tool. I'm going to connect the old NVR to the 3 that don't show up to see what's up with them and get their IP addresses so I can manually...

    Replaced NVR with new NVR and Cameras say "Failed to find Network Host"

    Mark: Thank you for your reply and help. You are correct "Camera IP address is in the wrong subnet to the NVR, e.g cameras are on 10.1.1.x and the NVR is on 192.168.1.x.". The old NVR had the cameras directly connected to the NVR and changed the cameras to 10.1.1.X and the new NVR has the...

    Replaced NVR with new NVR and Cameras say "Failed to find Network Host"

    I was running a Dahua NVR5216 but due to its limited bandwidth, I upgraded to a NVR608H-32-XI using a Dahua switch PFS4226-24ET-240 plugged into the NVR RJ45 port and an ePoE switch (EmpireTech 10-Port Unmanaged Switch with 8-Port ePoE) plugged into the second RJ45 port of the PFS4226-24ET-240...

    PTZ Tracking Resets to Preset when Person Stops Moving

    All great points I never thought about, "as is" sounds best and I agree with Wittaj, more spotter cams are the best solution for any blind spot outside of the PTZs presets. Thank you guys for your replies, much appreciated.

    PTZ Tracking Resets to Preset when Person Stops Moving

    I am trying to have the PTZs continue to track a person even after they have stopped moving for more than 10 seconds. I find that when a person stops moving for 5 to 10 seconds the PTZ will go back to its original Preset settings and then when the person moves (if they're in the initial Preset...

    Need Help - Weird kbps Issue with PTZs

    I took the NVR (NVR: NVR5216-16P-I) and router down to the other building where the PFT1200 is that feeds the SD8C845FG camera. I connected only the SD8C845FG camera to the NVR with no other cameras connected and plugged it into its original #6 RJ45 port on the NVR and had no changes, the video...

    Need Help - Weird kbps Issue with PTZs

    JDreaming, Wittaj, Flintstone61: I'm thinking the same thing, something is limiting the throughput of the camera. I have 15 cameras on a 16 port NVR consuming on average 114,700 kbps on an NVR bandwidth capacity of 320 Mbps (160 Mbps when AI function is enabled). I have unplugged 4 of the 4k...

    Need Help - Weird kbps Issue with PTZs

    I did a default reboot using the camera's GUI but no difference in performance. I'm wondering if the NVR may be the problem, the reason I say that is I have two SD8C845FG-HNF PTZ cameras, the older one has been up for almost a year and working perfectly since it was installed. The difference...

    The issue: very choppy video, especially when PTZ moves and zooms in, on the camera's GUI clock the time skips 2-5 seconds forward as well. Details: Comparing the two SD8C845FG PTZs at different locations on the property, the first (location 8) operates at 10,250 kbps while the second...

    Camera IR Illuminator does not Separate Day and Night

    BRF: I think you are describing the light sensor as the "Electrical ICR" setting in the "Day & Night" setting. I'll try and see if there is a way to check this evening before dark to see if the IR is on, I'll let you know. Thanks again for the help.
