    Beginner question - POE 12V, 24V, 48V

    In stock configuration, the 12 DC jack does not output 12 volts when you connect ethernet to POE supply. Some of use modify the camera and bypass the blocking diode to convert that DC input into an output. Such a mod has even been used to power an external IR light, but obviously the...

    Package Delivery Technique USPS

    It's a portrait oriented video, but my editing software only allows landscape. Hence, the time stamp is cropped off top of frame.

    Package Delivery Technique USPS

    Was looking through old footage to see how our cameras have progressed over the years. Found this gem from 10 years ago taken by a Hikvision eyeball. Well.... it DID get to the front door.

    Rainbow Intensity and Night Scenery on Security Camera.

    Rainbows this evening without color adjustment in post processing. As a scenery camera, the EmpireTech Color-4KT is more real than real. Night scenes are way more than one can see by eye alone. The still is at 12:30 (after midnight) and lit only by moonlight. Love it as a scenery and sky camera.

    SD49425XB-HNR - Odd spotting on the lens

    You are going to pull down the camera to take care of this. Access is via the rear hatch of the sphere. Then you pull the camera module out the rear to access the window. Not safe or practical to do at altitude.

    PTZ5A4M-25X vs PTZ4M-25X

    Good choice. Truthfully, I was a bit disappointed with going from the old 2MP to the PTZ4M-25X. The night imaging was bad enough that I had to add IR floods whereas previously I didn't need them. Just not sensitive enough on that 4MP on 1/2.8' resolution/sensor size combo.

    SD49425XB-HNR PTZ problems

    It this a newly installed unit? Mine are almost always bumped out of position (moved manually) as I adjust the mounting. SOP has become, reboot post install to establish a good baseline position zero.

    SD49425XB-HNR PTZ problems

    Here is what the vertical optical sensor and interruptor look like. When PTZ boots, the controller rotates until the interruptor blocks light across the optical sensor. That is how the PTZ board finds the motion limit. Horizontal direction has analogous optical sensor and interruptor. I...

    SD49425XB-HNR PTZ problems

    The PTZ mechanism does not have an absolute position encoder. Instead the system does an initial calibration for horizontal and vertical “zero” when PTZ boots. From that point on position is tracked based on stepper motor counts. If anything knocks the camera position or if a motion is hindered...

    Andromeda Messier 31 on EmpireTech PTZ5A4M-25X

    Set to 250 msec shutter and gain 65 to capture this morning. Companion M110 is just visible as a small smudge above M31

    PTZ5A4M-25X vs PTZ4M-25X

    Just for fun, I stacked three frames and did non-linear gamma to see what we can get PTZ5A4M-25X. I might have to get some software and do more frames. It's a security camera!!!!? The little companion galaxy starts to show up above the main galaxy.

    PTZ5A4M-25X vs PTZ4M-25X

    I don't have the cameras in same position, but these two shots tonight via PTZ5A4M-25X vs PTZ4M-25X should already give you a good feel for the night time difference. Mind, you the PTZ4M-25X would be even murkier without the extra IR floods. PTZ4M-25X 4MP on less than ideal 1/2.8" sensor...

    PTZ5A4M-25X vs PTZ4M-25X

    I have several of both models installed. The PTZ5A4M-25X 1/1.8 sensor is sharper even in the day and massively better able to get dim details at night. It really isn’t much of a competition. One is so obviously superior performing that the only reason to buy the 1/2.8 censored one is if one...

    More Stars, More Satellites, Plus Andromeda

    We didn't have a cloud clearing for the solar eclipse, but the night after, dark conditions made even a glimpse of Milky Way glow possible through wispy clouds. 01:50 into video, numerous satellites are traveling (east) down & across the sky. 02:17 to 02:23 the fuzzy core of Andromeda galaxy...

    Dahua day/night switch utility - DahuaSunriseSunset

    The new Web 5.0 GUI cameras will respond correctly to the old CGI calls if and only if one first sets them to Self-Adaptive working mode in the web GUI. That leaves them in a state that will accept the old CGI commands issued by software written to control the older cameras via...

    Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras

    Did two experiments today. 1. Test what happens if you power up the camera without an EEPROM in place? Is there a copy of the firmware in the battery backed up RAM? Result - Camera powers up and then the PTZ system does its horizontal and vertical motion motions. However, the camera does not...

    Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras

    That is the adapter I am now awaiting. End of April - early May estimated arrival. I have not (for decades) had any old school EEPROMS that would fit the 40 pin ZIF without an adapter. Back then, it was cobble together your own programmer with an external power supply, parallel port, and write...

    Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras

    From what I'm now gathering Xgecu makes their adapter incompatible between models of their programmers. The T48 (3rd Gen TL866II) won't work with TL866II or TL866II plus adapters. Given the same 40 pin ZIF socket and TL866II family, I had not expected that to be an issue.

    After a few hours of fruitless work trying to get MiniPro GUI installed and running on my Mac.... 1. MiniPro on MacOS will not work with the T48 programmer, not at least with the release version of MiniPro. Apparently, brewing from GitLab directly might get a revision that does support T48, but...

    PTZ Horizontal line setup

    I have never seen a circular level that can be read from BELOW. They all have been read from above and were designed to be placed atop a surface. Below the mounting arm would be upside down placement. I'm surprised you found a circular level that can be used in that orientation.

    Night of Fluffy Clouds

    You should be able to get some nice captures with that Dobsonian and camera. Envious here. You have a lot more light gathering power than our little security cams. Still, I'm floored at what the Dahua sensors are managing with their short shutter times. Every time I want to get a real scope, I...

    ROR!!!! That bodged on capacitor on the POE power board. I had forgotten I had added that ages ago to permit powering a microphone. Found it in an old thread of mine. https://ipcamtalk.com/threads/modification-sd49225t-hn-add-external-microphone-power.31714/#post-294280

    External IP66 / IP67 microphone for Dahua cameras?

    I mod the cameras to back feed 12 volts OUT of their 12 volt input for the Microseven. That lets the camera do the voltage conversion from POE and provides a handy 12 volt output. The mics pull very little power. Course, that will probably void your warranty and you also break the water tight...

    Orion Nebula and Satellite on PTZ cam

    Captured on an EmpireTech PTZ5A4M-25X last night. Orion had dropped low enough for the PTZ to aim at sword. Had to run with shutter speed 750 msec, but got some interesting footage. Might have to modify this PTZ to give it some more upward tilt range. The stock position sensor configuration...
