    Screenshots: IP megapixel vs Analog

    It could use some adjustment, but that post light in the front yard really messes things up for me and makes it difficult. I need to do something about that. The image is still very usable, though. You can also set up focus and exposure windows on the Axis.

    Nice, I have a P3346 as well on the driveway. There is a lot you can do with them, send motion detect ftp to NAS, set a schedule to switch day night etc. Not the "best" with low light but if you have enough light they work well. Plus they have a mic built in. I keep the shutter at 1/30-1/50 min otherwise you'll have a lot of blur. Have fun! They say 20fps for 3MP, 30fps for 2MP. I run mine I think around 10fps. Note that pic is probably not 3MP, given the aspect ratio. Should be better though at ~6-10x improvement in resolution compared to analog. You can also set up a view area and send that stream somewhere else. Work well with multiple streams also. Edit: to get the shutter speeds first select motion priority on the exposure otherwise they remain hidden. That took me a while to figure out just thought I'd mention.

    Where I am at so far

    Perhaps this has been covered but day night cams need to be focused at night. The iris opens up at night, and you'll have the least depth of field (amount in focus). During the day the iris will close, improving depth of field. I use a CNB TDN bullet (WCM-20VF) in one location and disconnected the IR. If the bad pics are the kit cameras, it looks like you might have a few things going on. One being mentioned already wrt flashback. Make sure the glass is still clean, some cheap cameras outgas and cloud the glass. If these do not have split glass this also will not help.

    nah, our 7-11 has a mixture. One or two were Honeywell.

    IR LED's vs. eye damage?

    Or get something like a nightlight and something with sense up. I mean the kid is just sitting there do we really care about a little motion blur?

    IR LED's vs. eye damage?

    Smart IR works by adjusting the exposure, on the CNB bullets. As an aside, it only works to a point. Can't compensate for say a Raytec RM100-10, still whites out.

    The difference there is that there is light that causes the iris to contract

    Nice, wish we had a spot like that archway to stash a real camera. Maybe in 5 or 10 years we will have tiny inexpensive MP cameras

    Ordered Surveillance System

    I would consider doubling up on cam1 and put on left and right of garage, since you have a gable to hide them in. Can get both cars in driveway, and front door/gate with good resolution. Besides a lot of trouble can come in through the garage, as most people do not alarm them...or leave the doors open...

    Example KT&C S20P4 in intercom speaker

    That is the beauty! We ran some extra wires into an Axis 243 for audio, and also ran the Nutone wires to the basement. We are still really impressed by how this project turned out - although as you'll see in a moment it is still a work in progress. House came with an intercom system (Nutone), which we have never used. Also, we can now play seasonal music out the speaker as we have an access point in the basement (Christmas party etc). Was not thinking (enough ahead of time), or I would have had pulled a shielded pair. At the moment I'm using one pair for +, one for -. Again, not thinking. And we pick up a radio station on the 243. Next step is to try using the twisted pairs for +/- (and maybe filtering), if that fails we'll need to pull more wires. Dreading it actually with the camera, Nutone wires and 2x cat5 it is pretty snug in there... That part was really an add on idea at the last second, we paid a local guy to fish the wires. Originally was going to do one, then I thought Cat5 is cheap just as easy to do two and we'll have access to the speaker. Took him 40 minutes, which is hours less than it would have taken us...we paid him for an hour $65.
  12. We use this under the deck, looking through the latticework. http://www.axis.com/products/m11_series/ This 1/4" vinyl material is very useful. Cut to size for the slots, single screw mounts camera. Slide it in from the back. Enclosure is mounted upside down, and is nice because it is easy to adjust and does not move once set (pretty easy to pick up for about $20 ea). Actually swapped out a P1344 (which was a tight fit in this enclosure) to use elsewhere, when we got a deal we could not pass up on the M1113. Do miss the autofocus on the P1344 though... Lens is a standard 5-50mm Bosch.
  13. Does not do well in low light, but has a nice picture during the day (1/4" CMOS) screen shot saved as jpg. Progressive scan and a fast shutter works great for this spot. Have captured squirrels jumping between the trees, hawks, etc.

    Need Help Building System for Home

    I've also used the WCM-20VF, same sensitivity as the dome but in a bullet form factor. I disconnect the IR though and use other lighting (just unscrew the cover and unplug the wires). Good sensitivity, if you're worried about burglaries make sure you have a few that are zoomed in and a few for overview is how we do it. If you have enough light (we use mostly CLF's) you can even run these in color at night and get a good pic. The domes are nice in that people do not notice them as much perhaps. Kind of balancing act, are visible cameras a deterrent or do they say I have stuff to steal?
  16. I would agree with it if they dispensed with the lux rating altogether. If one states lux rating they should back it up with scene, shutter speed, lens and IRE like Bosch.

    And some example pics, package delivery and a pic at night.
  18. Just for kicks I contacted Avigilon and got this response on the lux rating vs. shutter speed: "Avigilon does not provide the details of the test to determine our Lux Ratings because there is no formal industry standards and the actual Lux readings will change depending on the scene environment. Even given an f/stop and exposure it’s still matters what the reflectivity of materials in the scene is and what you require to recognize as acceptable ‘signal’ in SW. We recommend testing the cameras for the specific scene conditions to determine if it is acceptable and meets the expectations in the environment required." Axis does provide the details if you ask, I think it was at 1/6s if memory serves on the P1344.

    IR LED's vs. eye damage?

    Wow! Good stuff there. A little over my head, though. I'll advise the clients to put welding goggles on the kid just to be safe. Look at it this way, they needed to use lenses and a fair amount of power (I think around 15W or so for one of the cases) to get into trouble. The little LED's in bullet cameras have a lot less output, and are maybe run at a watt or two total. The new surface mount IR puts out an impressive amount, compared to the crappy little LED's in bullets. Now for some perspective look at the old Bosch Derwent docs for the halogen, lotta concentrated power and they had some distance guidelines. Still for the amount of power consumed not that much output.

    IR LED's vs. eye damage?

    You could look at the Osram safety guidelines, it shows you need a fair amount of IR power to get into the safety levels. That is what they say anyway. http://catalog.osram-os.com/catalogue/catalogue.do?act=showBookmark&favOid=00000007000098c70001003a Application Note Eye Safety This application note describes the possible hazards of infrared LEDs (IREDs) used for lamp applications
  21. Looks like a nice usable pic for 5MP and 1/50. I leave my P3346 set at 1/60s at night, due to blur (I have 2 100W equivalent lights on the side of the garage).
  22. Nice pic, noticed the shutter speed could go down to 2 sec. Do you happen to know how you have that set up for shutter speed?
  23. The best I can do is say I think it was a Toshiba 2TB for ACS.
  24. ...with VitaminD. Although I finally did add Axis camera station, I prefer running VitaminD for analytics around the house just to see what is going on and get email notifications of package delivery. And it is just so darn quick and easy to use. Can literally run through the whole day of events if I choose in under a minute. INSTANTLY plays back and jumps between clips. I have a P1346, and although I could save direct to VitaminD at 1.3MP, I can also set up a limited resolution view window to run analytics on. The reason this is important is that once you get up to a certain number of cameras I start getting limited by the writes to the HD, even though the computer is coasting. This gets tougher as we add more HD cameras. Actually running an I7 and 12 channels ACS and 12 channels VitaminD it is still coasting. I could set up a raid and may do that some day, but this is pretty darn slick. ACS writes to a separate HD. In this case I set up a view area called "2". Attached find the settings also for VitaminD. I also want to publicly thank Axis for great support, they even made me a video (without me asking) for how to set up the view area!

    Urban foxes on CCTV cameras

    Foxes don't like 850nm, I've seen them walk out around my IR. Does not bother the raccoons, cats, possum or deer though.
