Thanks for posting, it's always interesting see results. Looks pretty similar to a Lorex in quality that I had once upon a time. Motion floods will solve the lighting. On the other hand constant lighting can be a pretty good deterrent. I had the same problem with the bugs, the IR attracts them. CNB makes a good external IR unit at a reasonable price ~90 if you go that route. I would get the wide angle version. viewtopic.php?f=5&t=24535 In this example the IR unit was about 50+ ft away: viewtopic.php?f=5&t=24135&start=15

I have the same situation, end of cul de sac. Use a Axis P1344 w/ 50mm to get the plates going both ways at the top of the culdesac (only works effectively at daytime), and a P3344 dome as an overview (OK at night but not FBI grade photos). Even set wide it can get the plates coming in the driveway. Might be better answers for best low light performance but this is what I've done thus far. Someday might try a Arecont 3130 or Mobotix, or augment close up with some IR bullets. Started with analog cams but just could not get the coverage, and progressive scan blows analog away on motion and resolution.

I use Vitamin D, flawless. Easy to set up rules. Demo version is free and work for one camera limited to 320x240. I bought the full version, running it with 12 cameras on a quad core.

Here is the CNB at 15 percent:

P1344 at 20% on that one. The CNB is going through an old 2400+ at 50%. Did not even think to check the setting on that. All the pics are just screenshots off the mac, converted from png to jpg to get the size down. The CNB always looks that way though, it has a very distinct picture at night and tend to run at higher bitrate than other cameras, even during the day and on other servers like the 243 (around 15Mbs). Maybe something to do with the DSP, not allowing the jpeg compression to have that much effect perhaps.

cameras into Axis 2400: top left cnb BBM24F f1.4 5-50mm (0.03 lux, no IRE spec'd) top right bosch 0355 f1.4 5-50mm (0.09 lux 50 IRE f1.2) lower left panasonic 484 f1.3 (0.06 lux f1.2 no IRE spec'd) lower right sony ssc-dc593 f1.0 (0.07 lux 50 IRE f1.4 in turbo) illuminators: CNB MIR-1000 (30 deg 60m) $5 ebay (20m 48LED) Bosch EX12-8W (60 deg 3m wide angle version) Setup: Distance to illuminator to birch tree ~25ft. Illuminators are about 6 ft off the ground not angled. Cameras are a bit further, looking through a bay window. Panasonic when the sensup x2 is used is close to the CNB. Sensup not used in these pics. Have not found anything redeeming about the Sony, even using with a f1.0 it does not do that well at night. Turbo mode was not used here as it produced a very noisy picture. Ebay illuminator is very much a spotlight type effect. CNB provides a lot of light, might be even better up higher. Need to save my pennies and buy a newer Bosch D/N as shown by Shropna in an earlier thread. viewtopic.php?f=5&t=24135 I'd be interested someday to see a shoot out of a Mobotix and the Arecont AV3135, and how they compare to a good "analog" camera.

Pretty much, here is a pic with the 484 sense up x2

For $400 you could start looking at IP cameras. You can occasionally get a good deal on ebay, I've seen Axis P3344 sell for 3-400. They will record to SD also, although I don't love the mkv playback files. What I do at home is use Vitamin D for recording events, then either a NAS or SD to record it all. Just love the Vitamin D interface so easy to review what is going on. Lots of other options if you poke around the forum a bit. Personally I never want to see an analog DVR again (advantages of them to me would be low power consumption and low cost). Playing around with the Synology surveillance station today and while it works it feels clunky and limited options for ease of playback. From my playing around analog cams are very good at the low light stuff, and certain other things. If you have some light, you may want to consider IP cameras. No comparison to the picture quality during the day, no problem getting license plates in the driveway while still having some coverage. There are also 10 megapixel pics I've seen posted recently, wow.

I noticed this effect inadvertently playing with cameras (obviously as the camera is laying on it's side on the floor...). There seems to be a blur present. Do analog cameras wait 1/60s to take the next bit of the interlaced picture? I've searched around the forum and in general and have not been able to find an answer. Setup was Bosch 0355 into Axis 243, 35% compression and de-interlaced. 2 CIF (not blurred squished picture) 2 CIF expanded not blurred (but I think I've just tossed away half the information) 4 CIF blurred leg effect If this is what is going on, does someone make an analog camera that takes a progressive scan and then transmits NTSC? Or, do I need to use a progressive (e.g. IP) camera to eliminate this effect? Thanks, Mike

Here is directly from the axis site: http://www.axis.com/products/video/video_server/about_video_servers/deinterlacing.htm Also, I have a support ticket going and they are looking into it.

This website is a good read, but I have a question that perhaps someone with more experience than me can help with. http://www.cctv-information.co.uk/i/Why_LED_lighting_is_the_best_technology_to_use_with_CCTV I'm just curious why IR would have as an advantage longer distances? Or is this just certain types that have a different beam spread? Also it seems looking at sensor sensitivity vs wavelength sensors typically have less sensitivity at 850nm compared to the visible range.

The page for the 243 has that option checked, it is jaggedy without it. I think I'm going to open an Axis support ticket to try to get to the bottom of this. Thanks for responding with your experience.

Thanks Matt, very cool, was not sure how to use that but it's gradually starting to make sense.

I ordered something from 123 and it shipped from Canal Alarm Devices (tracking email from UPS). It was the correct item.

Shot through window, pics are screen shots off a mac using an Axis 2400. Only light is a pole light at the front of the houses. Crude comparisons but thought they might help someone. 1st is Samsung 130B (color only) vs. Bosch 0355 (B&W on right), both f1.4.

And just for kicks, the same scene partly illuminated from a MIR1000 sitting on the back deck. Cameras are inside, set up in the side bay window. One other thing I'll mention about the BBM24F, it has a connector which is (partly) for external control of the D/N but says "option" in the manual. It does work however.

Appreciate all the help you provide on the forum, so I grabbed that camera out from under the deck today. Here is the best I can do (as I've sold the Monalisa dome). On the left 0355, on the right BBM24F. Two pics, one is with the DNR cranked up on the CNB.

This was really confusing to me at first. Here's what I read to do somewhere and this seems to work. Although it seems that perhaps I did not need to change the camera port number on the camera? Anyway this works and I can use dyndns and these port names to access my cameras one at a time when a away from the house. The example below is a linksys router (all ports temporarily disabled) and Axis P3344. Hope this helps someone. To get Vitamin D to see the camera then I use 192.168.1.57:10057/

Maybe because it was so close, that would be equivalent to something further away moving faster? I was only a few feet from the camera. Here is an example further out, BBM24F into 241S. Squirrel moving quickly.

I've been reading a book by Vlado Damjanovski that just came and I think I've pretty much convinced myself that the fields are taken at different points in time for interlaced. Also, Sony shows progressive CCD sensors. I wonder if anyone uses these? http://www.sony.net/Products/SC-HP/pro/image_senser/progressive_scan.html

Hmm, good idea but I don't have one of those. I'm not sure we could see it as it happens so quickly, I notice it on playback on the computer. I'll add that to the list of things to try this weekend, we could drag an old CRT TV down from upstairs and use that? If it would work better I could just hook it up to the HDTV.

FWIW, that flood is mounted pretty high up maybe 16 ft.

Tried it horizontal today out the front bay window with a different camera, same thing for a package deliveryman. The other possibility is Vitamin D is doing something not right, or the Axis 243 is doing something. This effect is not present with my 1344 and Vitamin D. Hopefully this weekend will do another experiment and try to get Axis camera station running. Tried installing it on my girlfriend's old computer and it said the video card was inadequate so no dice with that. On the other hand, if interlaced fields ARE taken at different points in time 1/60s apart then there is nothing I can do this slow shutter effect will always be there. That is, even if I set the min to a fast shutter they will still be taken 1/60s apart and for moving objects this is going to cause some blur. I'll set it at 2CIF expanded for the time being but i don't like the idea of throwing away already limited analog camera resolution.
