PROBLEM RESOLVED Apparently, the Alnet Configuration Wizard is only half of what has to be done in order to get a lower resolution live stream. The second part is done in the Alnet CMS Professional software (the client software for connecting to the servers and viewing cameras/recordings). When using the client on the server (yes, I know that is a no-no) the CPU spiked with only a few cameras up (4 or 6). Same thing when viewing the cameras through the Server software. In order to get a lower resolution stream for the live view you have to: Be Logged in with Admin privileges in the Alnet softwart Open the client software Connect to the server Click on the Menu "Settings" Tab at the top of the screen Select "Camera and Motion" The "Display Settings:" field will pop up The server and camera you are changing will appear in dropdown lists at the bottom left hand corner Under the "Picture Quality" field you will see "Use settings when camera:" "Selected" will aready be populated; leave it at "full" in the video steam tab Hit the dropdown for the "Use settings when camera:"; the choices will be "Selected" (the default) "large picture" and "small picture". Select "large picture" then click the dropdown on the "Video stream: tab; select "secondary" (this will enable the VGA stream) Do the same for the "small picture" Click "Apply to All" in the bottom left hand corner so you don't have to go through each camera, then "Apply to Server" and click OK NOW CLICK ON THE SETTINGS TAB AND SELECT "SAVE SETTINGS" Disconnect from the server, close the client, reopen the client and reconnect to the server. Now, the CPU should be fine with up to 64 cameras showing on either the client or the server. And no more pixelation on the live view. We're pretty dissapointed that Alnet Tech support was unable to solve this issue.

Gringo - Since my last post I have been to the client's site and rebooted my power supplies; I noticed when I did that 3 ports on one Catalyst and 3 ports on another Catalyst still showed activity even though the power supplies were shut down. This would indicate that the switches were still supplying PoE even though PoE was disabled on those ports. Messoa is funky in that when offered PoE while connected to dedicated power supplies, the camera will default to PoE. This caused problems previously (cameras disconnecting for no reason) , so I had my client disable PoE to my camera's switch ports. I will revisit the client's site today. Wireguys - The camera's are not connected to two NVR's; just one. And yes, Alnet uses dual streaming. When using the Alnet Configuration Wizard, you have a choice of High Resolution streams only or High and Low. I initially set up High Resolution only but, that setup slammed my I7 to the ground; 100% CPU usage in Task Manager. I changed my settings to High and Low; 1080P for recording and VGA for live view; Task Manager now shows around 25% CPU usage. MaxIcon - Thank you; your analysis sounds logical. Sorry to hear that you have not been able to work around it. I will try manipulating the frame count settings if possible; also a call to Messoa and see if I can get this issue kicked up a notch. I will keep you all informed of any progress I make. Thanks for everyone's input; you folks are great!!!

That particular camera is about 40 feet from the dedicated power supply (not using PoE, and yes the PoE is turned off on the ports that the cameras are using. Remember that the images that are recorded are perfect; no pixelation whatsoever.

No, I'm not talking about resolution. Copy and past the link into your browser to view an example. https://www.dropbox.com/sh/l2bxaecu2t1rkje/cbE032nJvQ

Hi all, I am having issues with a IP camera system I installed at a client's location. The camera images in live view pixelate with motion (when someone passes through the camera's field of view). The recordings are rock solid. The system consists of: 31 Messoa IP cameras ( a mix of NDF821, NDF891 and NDF875 Pro). Cisco Catalyst 2960 Series SI Switches 3U Rackmount server with I7 2600K, Supermicro C7P67 Motherboard, 8 GB of RAM, SSD for OS and Alnet Netstation software, Windows 7 Professional 64 bit, Adaptec 6805 PCI-E RAID controller card Alnet server is set up with H.264 1080P resolution for the recording stream and VGA MJPEG for the live view stream (again, the recording stream is fine, the issue is with the live view stream). Both steams are set up for 15 fps. The cameras are connected to 4 different 2960 switches which home run back to the server room via fiber gigabit uplinks. The switches are the customer's; they have set us up with a VLAN for the cameras and server. I attempted to zip and upload an image, but got an error that the file was too big. Thank you

Thanks Soundy I've sent emails to Stardot and Computar regarding this. Computar just replied back stating "We guarantee 200 lp/mm on this lens" ( I inquired specifically about the new "A" series AG3Z3112FCS MPIR lens). Stardot has not replied yet (I inquired about their 4.5-13mm 5 Megapixel rated Varifocal IR corrected lens). I assumed, incorrectly, that they would not disclose this information since they did not include it in the lens specifications pdf. I just hope that they are being truthful.

Thanks for the response Nimrod. The chart that you recommended at Edmund Optics only resolves up to 14.30 lp/mm. I need something that can resolve 100 to 200 lp/mm. I just got off the phone with the good people at Edmunds Optics. They recommended the 1951 USAF Glass Slide Resolution chart. The price for the 2" by 2" glass slide is $120. This chart will resolve up to 228 lp/mm, but I don't think my boss will go for it. Up till now I've been spending between $100 and $150 MSRP for lenses for our Megapixel cameras, none of which do justice to 2 MP and higher cameras. I'm trying to do better by my customers. I have a job that we bid on that will require 5 MP cameras and I'm looking for a IR corrected Varifocal lens that will do justice to them (4-12mm range).

Hello all, Does anyone know of a reliable way to measure the lp/mm of camera lens? I have looked at the 1951 USAF Resolution Test chart, but the copies on the internet are low-res. You have to pay for the real thing and it can get pretty confusing on which chart to select. I would like to be able to resolve 100-200 lp/mm for 5 and 10 Megapixel lenses. http://en.wikipedia.org/wiki/1951_USAF_resolution_test_chart

Hi Soundy, The housing shape is unusual, but I've seen it in brochures. Could be a Hammer (made in Korea according to the brochure). Check out the link below: http://www.unixcctv.com/_e/HAMMER_Dome_Camera/product/IT-5625M/HAMMER_IP68_IR_Dome_560_in_Compact_Size.htm

I will be using Stardot SD500BN 5MP cameras with IR cut filters. The cameras will be fitted with Stardot 7.5-50mm IR corrected Auto Iris lenses.

Hi all, I am designing a system for a customer that requires coverage of a parking lot 192 ft wide by 266 ft long. I will have four 5 megapixel Day/Night cameras attached to a building at a height of about 15 ft, looking across the length of the parking lot. I have never installed IR Illuminators, but due to the current lighting of the lot I believe that I will need them. My understanding is that if I use 240 to 300 ft range Illuminators, my beam spread will only be 20-30 degrees on the far end. I was planning on using one Illuminator per camera. Any suggestions on the application of IR Illuminators will be appreciated.

I will do so tomorrow, thank you for all of your help. I'll update this post sometime tomorrow with the results. Thanks again Soundy!

I don't have much info on the switch (I believe it's either a 3Com or Cisco managed switch) but I pretty sure it supports Qos. I'm going onsite tomorrow so I'll have more information. The setup is as follows: 1 USA Security Hybrid DVR with NUUO SCB 5004 capture card and PI Pro software. 4 Bosch Extreme REG-X analog license plate cameras 12 Bosch NWC-0700 2.0 Megapixel IP cameras 1 Linksys SLM2024 switch 4 Linsys SRW2008 switches 1 3Com or Cisco managed switch as the root switch All Linsys switches connect to the root switch via fiber I know that's a lot of switches, but the cameras are distributed across a campus (I think six buildings)

The person I replaced installed the system. The capture card that he used is a NUUO SCB 5004, which is only capable of CIF resolution. CIF is too low for license plate recognition. The motherboard of the PC based DVR lacks the PCI Express x1 slot required by the NUUO 7000 series cards which do support D1 resolution. Also, two of the license plate cameras must use video servers due to the layout of the installation (it's a private school). Again, I inherited this situation from the person I replaced. Video servers seemed to be the cheapest resolution to the problem.

Hi all, I have a Hybrid DVR at a clients location with both IP and analog cameras attached. The problem is that the video feed from two of the analog license plate cameras freezes then accelerates so fast that the images disappear. The cameras are connected to Vivotek VS7100 video servers. I had a Vivotek technician remote in and view the problem cameras. He claims that I have a network issue, but none of the IP cameras show the same behavior. I have connected the license plate cameras directly to a portable montior and the video feed is fine. Does anyone have any ideas as to what the problem is?
