    PSA: Physical Gift Card Fraud

    Last August 2024 I had a similar problem with a $75 Home Depot gift card given to me by a neighbor I helped. The card was missing the PIN number. The store manager told me they had a bunch of cards with defective printing and pulled everything from the shelf. Mine must have been missed, or...

    Video/Event delay - Turn Sprinkler on when an IVS rule is triggered

    At my previous home I had a wild turkey problem. So I used a camera activated sprinkler to chase them off. I did not experience a noticeable time delay. I'd say it all happened within 1-2 seconds of IVS intrusion/tripwire detection. I used a low cost POE Amcrest turret camera that was flashed...

    New IPC-Color4K-T is Out of Focus.

    I checked the Empiretech data sheets: IPC-COLOR4K-X with 2.8 mm lens has 3 m (10.2 ft) focal depth. {That is confirmed by your photos} IPC-COLOR4K-T with 2.8 mm lens has 5 m (16.4 ft) focal depth. {Mine seems a little bit further than that, hence my claim of 6 meters} - Thomas

    New IPC-Color4K-T is Out of Focus.

    @Photon Farmer, thanks for the detailed instructions. I received the replacement camera today (ordered it before my Amazon return). Previous version was 3.6mm (my preference), but I replaced it with 2.8mm. I suspect focus looks better to me because the 2.8mm has a shorter minimum focus zone (1...

    New IPC-Color4K-T is Out of Focus.

    I disassembled the camera and found the lens fully contained inside a protective barrel. I tried pulling off the barrel piece, but gave up before I broke something. Time is running out -- My 30 day return window ends in two days. So I am taking the easy way out and will return camera. I did a...

    New IPC-Color4K-T is Out of Focus.

    I just added a third IPC-Color4K-T (3.6mm) to my Dahua NVR. First two have been in service for a few months and have very nice images. But the new one is slightly out of focus. Drat! All three are using the same settings. The camera is still within the Amazon return window. I have a week to...

    Would you trust this device?

    Nothing unusual. Bluetooth module, flash memory, accelerometer sensor, and battery. Has value if you like hacking/salvaging stuff from the junk drawer. - Thomas

    Amcrest AD410 dies in about 24 hours when connected to doorbell wiring

    Since the problem has occurred after two years of trouble-free operation, there is a chance the camera is defective. Or maybe the doorbell button switch is worn out and randomly making contact. If this occurs too often it may cause a WiFi disconnect because the battery would get discharged...

    Package Delivery Technique USPS

    I had a similar front door delivery experience with UPS. Here is the 14 year old (2010) video of the special delivery. Apologies for the poor quality. - Thomas

    Paintcam

    At my previous house I was having an ongoing problem with wild turkeys digging in the front yard gardens. They made a huge mess. I tried a couple different motion sensing sprinklers from Amazon but they were unreliable. The winning solution was a DiY automated water sprayer that used my home...

    Customize Display On Dahua Nvr?

    If you want to limit the Dahua NVR's screen to only five cameras then you can create a custom "Split-5" layout. However, two cameras will share a quadrant, so their width will be compressed. See screenshot. - Thomas

    Malware in EmpireTech IPC-Color4K-T webplugin.exe

    +1. Windows security reported my Color4K-T's plugin is Trojan infected. The Trojan is named "Win32/Wacatac.H!ml". The details say: "This program is dangerous and executes commands from an attacker." Fortunately the camera's web interface works without it. But it is worrisome that the plugin is...

    Amazon's "Just Walk Out" Checkout

    I live in a gated community that has a self-serve Amazon convenience store with "Walk Out" technology. The ceiling has a couple dozen cameras and shelving can sense weight changes to monitor when packaged items are removed or returned. Management told us the "AI" tracking cameras were incapable...
