    (on sale for $234) FLIR TCX T4325BN Thermal IP camera

    That's a pretty good price, considering that just the bare sensor chip itself (80x60 FLIR Lepton) is around $200, and a dev board including the module (no case or anything) is around $300. PureThermal 1 - FLIR Lepton Smart I/O Module v1.3

    (on sale for $234) FLIR TCX T4325BN Thermal IP camera

    Nice to see the price drop on these. The image from thermal cameras looks much more "jumpy" than normal video, due to the autoexposure range shift whenever something hot enters the frame. That makes good motion detection hard. One big advantage thermal should have outdoors is being blind to...

    Hikvision Dedicated License Plate Reading

    That's usually my goal also. Walking around my neighborhood I see a number of cameras under the eaves. Those in a contrasting color to the house stand out, but if they match the house color you have to look carefully to see them, at least from the sidewalk. A year ago I posted some video...

    DIY cheap IP cam with Sony IMX322 ?

    Thanks for the info! Yes, I am a big believer in external IR lights, my garage now has three separate IR medium-narrow angle lights for the driveway/sidewalk, and two longrange IR spotlights to pick up plates at 150'+ away.

    @framednlv : That cam looks good, except I have learned not to trust wifi. Do you know if there is an equivalent model with wired ethernet?

    DIY cheap IP cam with Sony IMX322 ?

    Update: the board-only (no case) camera I mentioned yesterday is not recommended by me at this point. It worked OK overnight, but now it is rebooting every 10 to 15 minutes. The power and network connections look OK physically to me. The camera log file doesn't say anything helpful. Also, each...

    DIY cheap IP cam with Sony IMX322 ?

    This is all the image parameter controls there are. Didn't come with an external light sensor and doesn't seem to use the internal shutter to figure out day/night, so the only option for day/night switch at the moment is the time of day control. Night image is not entirely hopeless. I'm...

    For what it's worth, I just got another board-level camera (no case), this one: IPC 1080P 1920 x 1080 1/2.8" CMOS Hi3516D+SONY IMX322 CCTV IP camera module board + HD IR CUT dual filter switch-in Surveillance Cameras from Security & Protection on Aliexpress.com | Alibaba Group I got the...

    DIY cheap IP cam with Sony IMX322 ?

    Thanks. I only just came across a user manual for a cam with similar UI settings (I didn't know some of them, Like "Dnc Threshold" sets the light level where the Day/Night mode switch happens, and "NightNTLevel" is a noise reduction setting)...

    DIY cheap IP cam with Sony IMX322 ?

    Note to self: with these settings, the night-time image is at least slightly better than before. I am not sure which setting was the key change.

    DIY cheap IP cam with Sony IMX322 ?

    One other thing: the camera's web login page HTML source contains an iframe link to a "Brenz" site (in Poland?) which I take as a bad sign (trying to load malware?) It seems to be what this article talks about: Warning! CCTV Cameras Sold on Amazon Come with Pre-Installed Malware I guess this...

    DIY cheap IP cam with Sony IMX322 ?

    I can't get a very good image on motion at night, even using three external IR spotlights plus the internal LEDs (which I can't turn off?) The web interface has an "auto" shutter mode ("Exposure mode: Automatic") with min and max settings labelled in milliseconds, but the min/max settings do not...

    DIY cheap IP cam with Sony IMX322 ?

    The MSIE web interface on this "Watchman" cam looks exactly the same as with an older 720p board cam I had from ebay a year or two ago. It also has the same odd glitch, that once you call up a menu settings screen, you can't remove it without shutting down Explorer and reopening it. Maybe...

    DIY cheap IP cam with Sony IMX322 ?

    Thanks for the reply. I assume the dome / bullet versions claiming that chip are probably using the same board inside, but maybe there may be some firmware difference, etc? Buying from ebay or aliexpress always seems like a blind leap of faith. I liked that one vendor in my first link had a...

    Has anyone tried using one of the cheap IP camera modules on aliexpress such as IPCam (1080P) 2.8mm LEN 1/2.8" SONY IMX322 + Hi3516 CCTV IP camera (built in IRC filter) + Audio-in Surveillance Cameras from Security & Protection on Aliexpress.com | Alibaba Group I am interested in this model...

    Camera for attic

    If there's a window, I presume it's a livable space. But just FYI, on summer days, a closed-in attic can get pretty hot, I have read up to 160 F which might not be good for the camera.

    Of course you should do whatever is appropriate to your situation. I was thinking about some place like the rural road I grew up on, where you might even see an extension cord simply run right over the road surface (!) from a house to a barn, to keep the hog watering trough from freezing, etc.

    However, if you managed to get power to it somehow, it would have a good view of your own house, and anyone approaching it. Maybe not good enough to cross under a road, but you can use a garden hose with a jet nozzle to tunnel under sidewalks and driveways: Shop Orbit Black Tunneling Kit at...

    Hikvision Dedicated License Plate Reading

    If you want a low-profile camera, it might be good if it was somehow combined with that light fixture. At night it would be nearly impossible to see due to glare from the light itself. During the day, it might escape notice if it blends into the design of the fixture.

    Camera type suggestion!

    My understanding is CAT5 uses 24 gauge wire and CAT6 uses 23 gauge. If all else is equal, that means the CAT6 will have about 80% of the voltage drop of CAT5 for a given current. If DC voltage drop was the only limit, that implies CAT6 could go 25% farther distance than CAT5 (assuming the...

    video analytics for everyone

    You're thinking like I'm thinking :). I'd like to get a "current status" page of thumbnails which show just those things, where the thumbnail is selected for the clearest view. Much better than simple motion detection. I think these new CNN programs watching a video stream could make a pretty...

    video analytics for everyone

    The project page is more about research than actual production use, the code I think just for demo. But it seems to be open-sourced so if you wanted, you could probably modify it to work with multiple input streams. GitHub - pjreddie/darknet: Convolutional Neural Networks "Darknet is an open...

    video analytics for everyone

    I guess the higher-end cameras have this built-in already, but it's kind of cool you can do it yourself on a Linux box using any image (but slowly, unless you have a serious Nvidia GPU). It's a convolutional neural network (CNN) trained to detect many different kinds of things in images. I'm...

    camera countermeasures, but a little bit late

    Dahua Ultra Starlight Varifocal Bullet (IPC-HFW8232E-Z)

    Thanks for doing these reviews, I know this stuff takes a lot of time. By the way, notice the appearance of the moving legs from 0:11 to 0:16 in this video. This is what I noticed on my "Eco-Starlight" also; small dark moving objects are affected by the noise reduction. The bigger-sensor camera...

    Reboot camera every week. Good idea?

    I recently noticed both Dahua camera models I have came by default set to reboot themselves once a week, in the early morning hours. So far I haven't had any problems with either type, but it seems possible that 30 seconds of dead time might be important some day. Just wondering, do people...

    ALPR: anyone have a 100mm lens they like?

    I'll try to get a picture when it's daylight. Without the optional lens hood, the camera + adaptor + lens is about 8.5 inches long. The front filter thread is 52mm. The Nikon is somewhat smaller than the Canon lens I was using before. If your range is only 150 feet, the field of view of the...

    ALPR: anyone have a 100mm lens they like?

    BTW, here's an example using the Dahua 4MP box cam with Nikon manual 100mm lens +C-mount adaptor. The lens is wide open at f/2.8 and this van is about 250 feet from the camera. The white "STOP" pavement marking is 330 feet away. Right now I record only 1280x720 resolution to reduce backend...
