    Wanted - a car alarm for people who refuse to lock their doors

    Given the huge variety of third-party vehicle alarms available today, I want to save some time by inquiring with the IPcamtalk crowd. Here's the issue: a great many people in some high-crime neighborhoods near me have essentially given up on locking their car doors. In their minds, it's worth...

    Using the Wyze Cam OG Telephoto as a low-cost daytime LPC camera

    I have been experimenting with the new Wyze OG Telephoto camera with 3X optical zoom, and I have learned that it can capture license plates on moving vehicles from a distance of about 40 feet, where the vehicles are traveling between 25 and 30 mph. Here's the good: (1) The camera costs only...

    An LPR success story

    Sometimes having an LPR system definitely pays off. Here's my latest story: On June 14, I recorded a couple of catalytic converter thieves hitting my neighbor's Prius parked right across the street from me in the early hours of the morning. I uploaded my video to YouTube, posted it on...

    Vehicle identification needed from IPCamTalk

    Once again I have a case where I'm trying to identify a car, and I'm hoping that someone can assist. Two catalytic converter thieves hit some cars in my neighborhood last week, including my neighbor's Prius across the street. I provided the video and the license plate of the perps' vehicle to...

    Camscript - a sunrise / sunset camera utility for MacOS

    Although many people have used the excellent Windows sunrise / sunset utility written by @bp2008, as a Mac user I wanted to create something that integrated with the SecuritySpy system on my iMac, without the need for virtualizing a Windows machine. The result is Camscript, a utility written in...

    Rekor Edge Pro - anyone recognize the camera?

    Rekor just released their own all-in-one LPR camera, but one that runs the Rekor Scout client and integrates into their subscription service. https://www.openalpr.com/product/edge-pro I assume that Rekor is selling some other company's camera, and branding it as their own. Does anyone...

    The wisdom of the IPcamtalk crowd needed once again to identify vehicle make & model

    I've got another situation where I'm trying to identify a vehicle used by a group of burglars, but without the benefit of a license plate (unfortunately). It's a small red or orange sedan. I've got some nighttime images as it passed by my PTZ, with my own Honda RAV4 blocking part of the view...

    Does anyone have experience with 740nm IR illumination with Dahua cameras?

    I've been using Dahua -Z12E cameras for LPR for a few years, but I've run into a situation where I may need to switch to 740nm IR illumination for nighttime imaging of the new license plates in my area (which have poor contrast at 850nm). Has anyone else tried this? Do Dahua varifocal cameras...

    Poor IR contrast in new Tennessee license plates

    I've noticed an issue with nighttime capture of new 2022 Tennessee license plates. The white lettering on a blue background washes out almost completely in IR light, making the plates barely readable. Has anyone encountered similar issues with other plates? I'm wondering if additional IR...

    Has anyone had success using a fixed lens mini-bullet camera for LPR?

    I've been talking to a neighbor who wants to install a camera that is suitable for LPR, or at least LPC. Due to HOA concerns, he is thinking of trying to install a couple of hidden mini-bullet cameras in a mailbox post near the edge of the road. His question to me: "Would cameras this small...

    Can anyone identify the SUV driven by these door checkers?

    See the following video. The plate is clearly stolen. The SUV looks like a Honda or Toyota, but I'm not positive. Can anyone positively identify it?

    When you know that you have "arrived" with your camera system

    No image to show, but just wanted to mention that last week a scruffy looking guy covered with tattoos walked past my house just past 5 a.m., saw my cameras, and gave them the middle finger as he sauntered past. So now I know my camera system has "arrived". Once my auto-tracking PTZ is...

    Does bacon grease on dog poop really work?

    Okay, I realize that this is a weird title for a thread, but the problem is real. Twice in the past week the same woman has walked her dog by my house and let it poop on my lawn. Then she pretends to pick up the poop, and instead walks away leaving the mess there. She wants everyone to think...

    OpenALPR on a Raspberry Pi 4 and the Jetson Nano

    UPDATE: I've updated the title of this thread to better reflect the direction it has gone, as the Jetson Nano SBC has turned out to be a much more workable solution. ___ Has anyone tried installing the latest Rekor Scout (OpenALPR) client on a Raspberry Pi 4 running Ubuntu? I am toying with...

    Can anyone ID this vehicle's make and model?

    The following was sent to me by a neighbor one street over. The people in this vehicle stole several packages along his street. I'm going to do a search in OpenALPR, but it would be useful to know the make and model, which I have no eye for. Can someone ID this vehicle?

    Why the retreat from 1/1.8" sensors in the latest Dahua bullet cameras?

    I've installed a couple of Amcrest IP8M-2957E mini-bullet cameras with 1/1.8" sensors, and I've been very pleased with the resolution and nighttime color performance on both of them. This camera is the equivalent of the Dahua IPC-HFW1831E which is now EOL, so I began looking through the latest...

    You really shouldn't try to commit burglaries in your own car

    I captured this little incident on my cameras last night. According to the police, the vehicle has not been reported stolen, and the detective I contacted thinks it is being driven by the owner. He has placed a BOLO alert for the guy, so I'm guessing the police have had interactions with him...

    A mugging ... before and after

    I meant to post this story a few days ago, but had too much on my plate. Last Sunday at about 10 p.m., a police officer knocked on my door and told me that someone had been mugged right down the street from my house just an hour earlier. The victim said the muggers ran up in the direction of...

    Attempted trailer theft across the street from me

    Last Friday my neighbor called and told me that someone had tried to steal the trailer that his contractor had left parked in front of his home overnight. The wheel chocks were missing, and a lock was broken on the hitch. He knows about my camera system and asked if I could identify who did...

    Any advice on mounting a PTZ camera on a 45 degree angle beam?

    I am thinking about mounting a Dahua SD49225T-HN PTZ camera beneath my deck. Unfortunately, the best option to place it in such a way as to keep it out of the worst of the weather is to mount it on a support beam at a 45 degree angle. This wouldn't be a problem if I mounted the camera on the...

    The squirrel must die

    Tonight I checked my cameras after dinner and found that two of them on the same side of the house had dropped out completely, about 5 minutes apart. I had an "uh oh" moment as I remembered the squirrel that has been traveling over our roof to get to my wife's tomato plants on the back deck. A...

    Can anyone identify this car?

    We had a group of female car door checkers cruise down our street last night. Normally I'd check the tag with www.vehiclehistory.com to confirm the make/model/year of the vehicle, but in this case the car had a temporary paper tag. Can anyone tell what car they were in? I suspect they were...

    How are various cars being entered and stolen in my neighborhood?

    I'm throwing this out to the members of the forum to see if someone has some information relevant to auto thefts and break-ins that are taking place in my area. The latest example: two nights ago, a 2012 Land Rover LR4 was stolen while parked on the street in front of a neighbor's home. This...

    Possum on a late night raid

    This is the third night in the past two weeks that this small possum has raided the red milk crate near my back door. And what does it contain? Doggie poop bags from our dog walks, which we toss when we take the kitchen trash and recyclables out to the bins in the alleyway. (The dog poop also...

    The mystery of the "invisible" license plate on my LPR cameras

    I have run across a very interesting phenomenon with my LPR system, and I'm wondering if anyone else has encountered this, or can suggest a change to my camera settings to resolve it. Quite by accident, I realized that the specialty plates on my wife's RAV4 cannot be viewed while my Dahua...

    Cameras with human figure detection for perimeter security

    I'm doing a bit of research for a friend who is trying to create a perimeter security system, and who needs several cameras that can detect human figures. Here is what he wants: (1) The camera must be mountable outdoors. (2) The camera should be able to detect a human crossing the field of...

    Recommendation for an upgrade from SD49225T-HN

    My Dahua SD49225T-HN has been a workhorse in my camera system, but in the last few weeks it has become unreliable, with reboots and freezes every couple of days. I can power cycle it and bring it back to life, but it never lasts. I've tried downgrading the firmware, which helped somewhat, but...

    The danger of texting while driving ...

    This is not my video, but was recorded last week by my neighbor's Nest camera one block over. crash-lindenave-mar2019 The driver was (you guessed it) reading a text message on his phone. He had only minor injuries, although the police and paramedics had to roll his car back over to get him out.

    Some thoughts on assembling a dedicated LPR system

    Many neighbors who have seen what my camera system can do have commented on how they would love to have LPR cameras for their own homes, but they're too intimidated at the idea of installing and maintaining them. In some cases, these are people who already have Ring or Nest or Arlo cameras, but...

    Slides from my security camera presentation

    Last Tuesday I gave a presentation to my neighborhood association about choosing the right security cameras (a major point of interest given the property crime that residents deal with). In case anyone is interested, here is a link to a PDF of the slides: Security Camera Presentation Oct...
