    Plan for more than 2 cameras... package thieves

    I'm right there with you. Anyone who walks past my house will see 4 cameras pointed at him. If he walks onto my front porch, there will be 2 more. Back alley / back yard, 4 more, plus one on each side of the house. It has its desired effect. A few months back, we had a guy on a bike go down...

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

    I was always under the impression that toll road cameras didn't use IR, but instead photographed plates using normal (bright) roadside lights for illumination. Regardless, this trick would still be useless in the daytime. And perhaps that also explains why this trick isn't used more often...

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

    That's very interesting. Whatever they're using is absorbing the UV light very effectively. If this stuff becomes widespread, it could put a real crimp in the utility of custom LPR systems, at least at night. But the more interesting question is "why"? Are they anticipating the use of LPR by...

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

    Thanks. Your suggestion to increase the contrast was a very good one. I just got a "hit" on a D* temporary paper tag, which I've never been able to read in the nighttime before. I always assumed that a paper tag wouldn't be readable. The image isn't great, but it can be seen. My cameras...

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

    I've tried increasing the contrast and turning off noise reduction. The RAV4's license plate is still washed out. But standard plates look just fine, as can be seen from the latest two images saved by my system (attached). Her specialty plate is a women's veteran plate with a blue pattern on...

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

    What is posted is actually a crop of a much larger image. It's a compromise between capturing a sufficiently wide view versus capturing enough pixels to identify the plate. I'll crank up my contrast and see if that helps.

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

    I'll try viewing the plate with my PTZ camera in its normal nighttime mode and see how readable it is.

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

    The distance is only about 70 feet. The angle is the best that I can do with the cameras mounted under the eaves of my roof, given the surrounding obstacles. But this isn't a matter of angle or distance, as the other plate image shows. It's a matter of contrast, and only for that particular...

    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...

    Recommendation for starting a home security system

    Blue Iris runs on Windows, and SecuritySpy on MacOS. If you want a Linux option, look at Blue Cherry (plus others such as Zoneminder). Blue Iris supports every feature that a standard NVR can provide, and more. The $29.95 / year ensures that the software will be upgraded and maintained, which...

    Recommendation for starting a home security system

    One thing to add to the post by @SouthernYankee: a lot of choices for your surveillance system will depend on your knowledge about computers. If you are comfortable with computer systems, and understand the basics of networking (e.g., port forwarding through your home router), then a Windows...

    4MP Budget Cam Black Friday Giveaway

    What the heck, I'm in. I'd install one of the cameras on the side of my house, under my deck, to provide coverage to the entrance to my basement. It's currently a blind spot that I've been meaning to do something about. This will give me the motivation.

    Hikvision alternatives for home security?

    I would suggest the following: (1) Set up internal camera systems at your home and office that record to NVRs. Make no attempt to deal with accessing those cameras outside of the local network. Those cameras will provide high resolution archival video footage. (2) Add a few Wyze cams set...

    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...

    More proof that Ring sucks.

    People ask me for camera recommendations all the time, but: "I don't want to spend too much money. Should I buy a Ring?" Then I tell them that for the price of one Ring, they could at least put up half a dozen Wyze cams with SD cards, and get coverage from multiple viewing angles, along with...

    Help with LPR camera

    From the data sheet, this camera only works with vehicles moving up to 25 mph. Even cars on residential streets often go faster. Is that sufficient for your needs? You'll get much better performance running a couple of Dahua IPC-HFW5231E-Z12E cameras connected to a cheap Windows PC with an...

    Recommendation for an upgrade from SD49225T-HN

    My SD49225T-HN does double duty. During the day it focuses down the road and acts as a backup LPR camera for situations where a parked car blocks one of my other LPR cameras. At night it swings around and zooms in to monitor my parked car, just in case some door-checker tries to break in...

    Recommendation for an upgrade from SD49225T-HN

    I don't disagree, but reliability in my camera system is paramount to me. My other Dahua cameras are as solid as rocks, but my 49225 is no longer dependable. I hate it when I check my camera footage from the night before and see that it quit working, without explanation, for several hours...

    Recommendation for an upgrade from SD49225T-HN

    Thanks. That will be my last resort. I am putting off doing so because it will be such a pain in the rear getting to the camera. :-)

    Recommendation for an upgrade from SD49225T-HN

    If you mean the factory reset via the web interface, I have. I'm waiting to see if that resolves the erratic behavior. If not, I intend to upgrade or replace the camera, hence this thread. I know there's also a reset switch inside the camera that is accessible via the removable back panel. I...

    Recommendation for an upgrade from SD49225T-HN

    I've already browsed through the approximately four dozen different PTZ models (without pricing information, of course) on the Dahua site. But what I'm looking for is a recommendation from someone who is using one of them, at a price point that is not out of line with what I paid for the...

    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...

    Found this after I stepped in it...

    The same thing happened to me, which I caught on camera and shared with my neighbors on Nextdoor. Very quickly the people along my street identified the address of the "poopetrator", and soon made a habit of tossing his poop bags back into his yard. He moved away a few months ago, so...

    Video removed - FedEx drives over neighbor's dog, no brakes, doesn't stop

    As @erkme73 previously mentioned, the driver was afraid of dogs (understandable - as a delivery driver, she might very well have been attacked in the past), so stopping the van with another dog in hot pursuit would have been the last thing on her mind. She might have thought that she would be...

    Video removed - FedEx drives over neighbor's dog, no brakes, doesn't stop

    Hopefully FedEx will at least offer to pay the vet bills. However, I would advise your neighbor to think twice about releasing the video to the local media, because it might backfire. Many animal lovers will be just as quick to blame him as well, for letting his dogs run loose and chase cars...

    Video removed - FedEx drives over neighbor's dog, no brakes, doesn't stop

    Keep in mind that he/she was driving along a gravel road, which is noisy. I wonder if the driver even saw or heard the dog in front, or thought that he/she had simply hit a pothole. The driver's attention might have been focused on the dog running behind the van, which was much more visible...

    LPR camera location

    @bigredfish is absolutely correct. Running OpenALPR on an nVidia GPU can improve plate recognition from less-than-optimal angles, but in your case you'd be pushing it too far. Is there any way you can run Ethernet cable down to the shrubbery beds in front of your house? You could mount...

    OPENALPR - Cloud config question..

    I'm running a Dell with a 4th generation i7, so I'll see how it works. My interest is in showing people how to set up an ALPR system independent of any other surveillance system. Running it on Windows 10 as opposed to Ubuntu makes that task a bit easier for the layman. What I've found is that...

    OPENALPR - Cloud config question..

    I wasn't aware that Nvidia GPU acceleration was now available with Windows 10. Thank you for pointing that out! Although the OpenALPR agent is rock-solid with Ubuntu, I'd much rather work with Blue Iris to handle the video recording on the same box. My project for next weekend awaits .... :-)

    Thief arrested

    Great work, @bigredfish! Speaking of the limitations of Ring cameras, I wonder if a company like Ring or Nest or Wyze will ever market a camera with optical zoom that is capable of LPR. They could make a mint selling the same type of cloud service that OpenALPR provides.
