    EmpireTech 2024 Spring Sales

    Some good deals there. But sadly a white IPC-Color4K-T 2.8mm is not on it. Will have to talk myself into spending more on a fresh new one. Or wait for the next sale. - Thomas

    Is a Dahua NVR actually 1U or 2U in a rack?

    I wanted to rack mount my NVR5216-16P-4KS2 using a generic 2U shelf kit. But the required depth was not friendly to the rack size that would fit in the coat closet. I ended up wall mounting the NVR, which is now hidden behind some jackets.

    Pros/Cons Bullet vs Turret

    Not that I have performed a scientific study, but I swear turrets do not attract wasp/hornets as much as bullets do. I think the bullet's smaller lens "hole" is fooling them that a nice place to nest is inside. For sure, turrets are less "commercial" looking. So WAF is much higher on them.

    Upgrading Alarm/Security System - Seeking Opinions

    1. No. The DLS programming software is old and it communicates via the panel's serial port. 2. Chime is the same for open/close. BTW, the chime sound is depends on the keypad, not the panel. Some keypads have only one chime noise. 3. No. 4. No. 5. Yes. One of the reasons I like the Envisalink 4...

    Upgrading Alarm/Security System - Seeking Opinions

    Looks like you have made your choice to stick with DSC. That's what I did. Your situation is similar to one I faced a few months ago. Twenty years ago I installed a DSC PC5010. It was expanded to about 30 zones to monitor all the wired entry switches and other sensors. I had a monitoring...

    false triggered video tampering alarm when IP cam switches from night mode to day mode

    Perhaps a workaround is to set the Video Detection Period to ignore the timeframe it switches to day mode. - Thomas

    Question on Dahua Live View through HDMI monitors

    Perhaps you have Display->Tour Setting turned on. If that's the case then disable it. Or maybe your Uncle has a mouse on his system and is clicking it after you leave. Doing that can direct the screen to show only the camera that was clicked on. Click it again and it will return to multi-view.

    Review-Dahua/EmpireTech Dual lens IPC-HDBW5441F-AS-E2 (The Boobie Cam Upgrade)

    Currently using a IPC-HDBW4231F-E2-M at the front door, but thinking of upgrading. Does the IPC-HDBW5441F-AS-E2 allow face detection on one channel and IVS on the other? - Thomas

    Dahua cameras accessing address reserved for documentation

    I don't know where I read it (so I could be wrong), but I think some routers support "adblocker" protection that redirects suspect traffic to the 203.0.113.x range. So check your router for such a thing. - Thomas

    NVR Help

    I feel like I'm one of the few NVR users around here. I previously used an inexpensive Dahua DHI-NVR2116-I with 10 cameras and was VERY satisfied. But I recently moved and installed a used Dahua NVR5216-16P-4KS2 that I purchased from another forum member. Although the new house is smaller, I'm...

    IPC-T2431T-AS Has Poor Focus, need advice

    A year ago I purchased four refurb'd IPC-T2431T-AS from Andy during his 2022 Memorial Day Sale. Got a good deal, only $45 each. Two installed outdoors, one in my garage, and another in storage as a backup. These are used as observation cams (I have other Dahua's in strategic places for...

    Have you tried a cold boot? That is to say, unplug it, wait, plug back in. Beyond that, a factory reset might restore the broken email function. - Thomas

    At what point do you retire an SSD?

    I can't offer any practical advice on when to retire an aging SSD that still has good health status. If your version/release of the 850 Pro has a known good track record then I would continue to use it (classic watch and wait). Have you enabled Over Provisioning? Doing that usually extends the...

    Blur on specific spot 5442-ZE

    I had a random blur on a Dahua camera (boobie dome). A bit of hair-pulling was involved while I chased the problem. It was just condensation inside the camera that only appeared under certain temperatures/conditions. Took camera apart, dried the desiccant bag and allowed the internals to dry...

    DSC 1864 install opinions wanted

    EOL resistors will be needed on every zone if you have setup your system configuration to use EOL resistors. This configuration is selected in Program [013] Option 1and Option 2. If you have disabled End-of-Line resistors (not a typical choice) then resistors should not be installed. - Thomas

    DSC 1864 install opinions wanted

    I just moved into a new home and started setting up a new DSC PC1864 in it. Was previously using a PC1832 in the old home. DSC PowerSeries panel installations use 5600 ohm 1/2 W for wired zones (single or double EOL configurations) . Very low current bells/sirens will need a 1K across the bell...

    Recommendations - Interior / Ceiling Mount / POE / Unobtrusive / Fixed & PTZ

    I wanted to observe a big glass sliding door and part of a dining area. Originally I planned on using a Dahua camera with their thru-ceiling mount (10 foot height). But the required hole is large and I was concerned about the future sheetrock repair I would need to do when the camera became...

    Grayscale videos after DVR replacement

    Looking at the IMG_5982 video, I would say that it is an NTSC camera and the DVR's cam input channel setting is configured for PAL video. This best guess is based on the "fat" aspect ratio and missing color. - Thomas

    Grayscale videos after DVR replacement

    I have seen the black/white symptom when the analog camera's video signal mode (NTSC/PAL) did not match the DVR's video input setting. But you mentioned your new DVR has an Auto Video Mode, so I assume that means it would configure each video channel's NTSC/PAL setting for you. So something...

    NVR Camera Ports

    You'll have to get creative if you need wall mounting. I wall mounted my NVR5216-16P in a coat closet using some DiY brackets (3D printed, ABS plastic). The brackets are at each corner and only screw into the wall (the NVR is not modified). BTW, the NVR is normally hidden behind jackets...

    Mystery Icon on Dahua NVR Live Screen

    My Dahua NVR is running V4 software. There are two icons on the main live view screen that are next to the timestamp. See screen closeup snapshot below. I know what the Bell icon does (alarm Arming/Disarming function). But next to it is a broken half circle with arrowheads. A "W" toggles in...

    Program for flipping cameras to day/night on Linux

    I recall that if the cameras are installed directly on the NVR's POE ports then they will be on a private subnet that is blocked from the LAN. - Thomas

    Water Meter Box Cover - Where did it go?

    That's insane. Finding the cover at the pond is like winning the lottery. My IP cameras have solved so many mysteries for me. For example, last week Amazon said they "delivered a package to my mail room." I couldn't find it anywhere -- And my house doesn't have a mail room. Looking at the...

    Tool for discovering IP camera with unknown IP address.

    I use wakemeonlan on my WIN10 desktop to scan the local network for IP devices. Works well, does not install on the PC (standalone operation). https://www.nirsoft.net/utils/wake_on_lan.html It only scans the subnet that the host PC is on. So if your cameras are configured for a different subnet...
