Why not just use digicams that support video? They are dirt cheap compared to security cameras and take video that is far superior. In addition, NLEs like Premier and Final Cut will import the video without any problem. Best, Christopher

Are there any GVI autoIP software license resellers on this forum? Best, Christopher

I hear ya'. The problem is that ONVIF notwithstanding, the specifications look great. Are there any other 1.3MP 1/3" Exview progressive scan CCD IP POE minidomes that are half the price of the Panasonic 502? Best, Christopher

Understood, but my Exacq rep tells me that Exacq ONVIF is currently not compatible with Samsung ONVIF and that may still be the case when Exacq 4.4 is released. So, even if I wait 6 to 8 weeks for 4.4, it still may not support the Samsung ONVIF cameras. So, I need a back up plan. I think Samsung supports all my existing cameras (Axis and Panasonic), so perhaps I should drop Exacq and switch to autoIP. Anyone know the pricing? I'll contact GVI tomorrow and report back if no one knows. Best, Christopher

I would like to purchase and install one of the new Samsung GVI cameras. I currently use Exacq to monitor cameras. Exacq does not yet officially support Samsung ONVIF cameras, and although Exacq plans to release support for ONVIF in another month or so, it is not clear that they will support Samsung ONVIF cameras. Therefore, I may switch to GVI autoIP. Does anyone know the single camera licensing fee for GVI autoIP? Best, Christopher

Judging from the specs alone, the Samsung GV-NC-201VO could be the camera that I've been waiting. I expect the low light performance will be significantly better than my Panasonic 502, and at about half the price. http://www.gviss.com/products/ip/gvnc201vo.php?pg=overview#prod_extras Best, Christopher

Good point. I checked the Exacq website and I don't see any Samsung cameras listed. I sent them an email requesting information on support for this camera. Best, Christopher

I skimmed the manual. The Samsung does not have Auto Back Focus. Even so, 1.3MP 1/3" Exview Progressive CCD H.264 IP POE in a sub $500 IP66 mini dome could be a winner. Best, Christopher

Axis makes quality products, but low-light performance is not their strength. Best, Christopher

Which lens did you get? What do you think is the maximum field width in which the plate is still readable? Best, Christopher

Thanks for posting the images. Not absolutely certain, but I think the IR leds are on all the time. If the IR leds fail, I suppose there could be sufficient ambient IR for them to work during the day. Either way, the cameras have an IR bandpass filter to block the visible spectrum of the headlights. Best, Christopher

In addition to a high power IR source, what else is special about the Bosch Extreme REG-L1 license plate camera? In particular, why are headlights so dark at night and license plates so bright? Do these cameras have a filter that is notched to pass IR and block the visible spectrum? Best, Christopher

Which model do you have? It is possible to focus the beam. Both RayMax and Bosch/Extreme have IR emitters with different beam widths. Do you recall your horizontal and vertical angles? If I purchase one, I'm going to try two locations, one location is up about 15', and the other is level with the plates. The latter location will certainly do better, but I'm hoping the high location gives satisfactory results. Yes, I wish there was an option to purchase the camera and IR as separate units. Why? The rear plates have a light, but are otherwise the plates are identical. Is it the plate light that makes the difference? The police in our town are extremely responsive to any suspicious vehicles driving through our neighborhoods. If I see a plate with a cover cruising around at 2 am and report it, the police will pull them over for questioning. Best, Christopher

Thanks. After more reading, it's apparent that the REGL1 uses the IR leds 24/7, even during daylight hours. It uses an IR bandpass filter to block the visible spectrum, and uses an IR sensitive sensor. I'm getting ready to spring for one of these. I'm leaning towards the 75mm, but my concern is that the IR source has same beam pattern for all models, which would mean it is not optimized for 75mm. Does anyone have experience with the REGL1? Do they adjust the beam pattern to match the lens? Best, Christopher

Check out the lux ratings of the 7111 and 7211. They have the same lux ratings, but at different apertures. Do you suppose the lux values are at the sensor, or do you suppose this is just sloppy specifications? Best, Christopher

Are you trying to find a camera with an IR cut filter, or are you trying to find a camera that will perform well at your location? Just because a camera has an IR cut filter does not mean it will perform well during day and night. Best, Christopher

Yes, and other features may include: improved low light performance, a sensor that is sensitive to IR, a lens that is optimized for both visible and IR, and possibly an auto back focus since IR typically has a difference focus point. Best, Christopher

I think I found the answer here http://www.balticnordic.com/license-plate-recognition-filter/supplier.html Best, Christopher

Can you post and/or send me the list of the ten prices. Thanks in advance. Best, Christopher

What is the pricing on the exacq ELS? Best, Christopher

No, it has to do with improving low-light performance. Fewer pixels means larger pixels, and larger pixels means more photons per pixel. Camera design is all about trade-offs. During the day with ample light, you can afford the losses of a bayer filter for color and afford the losses of smaller pixels for increased resolution. But at night in low light, color and resolution are not worth anything if you can't see an image, so you are willing to give up color and resolution at night to gain the ability to at least see something, albeit in b&w and lower resolution. Best, Christopher

Oh, and one more benefit. The .exe program is like an exacq client, which means it will play back multiple streams simultaneously. For example, if a burglar moves from one camera to another, all the selected streams can be written to the .exe file. When running the .exe file, you can play back one monitor, switch monitors, or watch all monitors simultaneously, just like the exacq client. Very slick. Best, Christopher

It's not a typo. The benefit of the .exe file is it will run on the ubiquitous Windows PC with no worries if the proper codec is installed. Best, Christopher

The 502 has auto back focus, which is a welcome feature. Low light performance is not exceptional, but my one copy has been quite reliable, as you might expect in this price range. Best, Christopher

Good question. Unfortunately, there is not an easy answer. Unlike the photo world where there have been well-established and well-understood standards for features such as film sensitivity since the dawn of photography, the CCTV industry pretty much depends on each manufacturer to come up with their own ratings for features like low-light lux. It's really not possible to purchase one camera over another based on lux ratings on a data sheet without knowing more about the manufacturers and the camera models. Best, Christopher
