I've this re-labelled Dahua camera that was gifted to me by a brother-in-law that runs a security firm in Europe. Knowing it was really a Dahua cam under the hood, I set out to find out what model it really was so I could find up-to-date firmware for it. I eventually figured out it was a Dahua...

My plans to acquire another Dahua camera being torpedoed (ref: "Affordable" PTZ Starlight Cam?) and Hikvision having an execrable history of questionable behavior, I wonder what are my affordable options, short of shudder Reolink? Suggestions on brands at which I should be looking? Not...

I'm wondering if Dahua makes a relatively capable PTZ camera that would give me capabilities similar to, say, a SD5A445XA-HN, that's more affordable? We have a large shed (or very small barn, depending upon one's perspective) about 100 ft. back of the SW corner of the house. The front of the...

For a couple months or more I've had a problem with my Dahua IPC-HDW5231R-ZE cams going briefly off-line for a minute to a minute-and-a-half on an irregular, but fairly frequent basis. Having eliminated the NAS and Surveillance Station software running upon it as the culprit, I assumed it was...

The latest release of Synology Surveillance Station now has support for Dahua IVS. Before I go to the trouble of messing with it, is line-crossing any less susceptible than motion detection to "false positives" such as the shadows of trees moving on a sunny, windy day; headlights flashing...

I have an X-Security model XS-IDPM985ZWH-2 IP camera that was gifted to me by a relative in Europe. It is the same form-factor as my Dahua IPC-5231R-ZE's, and the camera UI appears to be identical to them. In fact, other than it has no sound, it seems identical to the 5231's. The current...

I searched. I got hits on "Smart Codec," but was unable to find any pros/cons discussions other than you can't use SC and IVS simultaneously. So if you're just using plain old vanilla motion detection in the cameras, as I am, are there any downsides to using Smart Codec? The firmware...

This is the back corner of the house/garage junction, viewed from the corner, approximately where I think I'd put a camera: That line represents about thirty feet. The location is labelled "Back Door," in the drawing below, for reference: Any recommendations for a camera to cover that...

I'm inexplicably fascinated by this new Dahua PTZ1C203UE-GN, currently being discussed in New Dahua Bullet PTZ - PTZ1C203UE-GN Question: What is the best/recommended way to wall-mount such a thing on a vinyl-sided exterior wall? Something like this, perhaps?

Here's a crude drawing of the house and attached garage. The three red blobs indicate current cameras. The light grey marks on the black outline are the major vulnerabilities. All other windows are impractical for break-in purposes. Mainly due to height. The home also has a wired, monitored...

Just experimenting with and learning these Dahua IP cams (2 x IPC-HDW5231R-ZE outdoors, 1 x IPC-HDBW4231F-AS indoors, so far). All three cams have V2.800.0000005.0.R, Build Date: 2019-03-25. Had been experimenting with Camera -> Conditions -> Conditions -> Sensitivity on the 1st 5231. Added...
