I would have to say your only option is an onsite NVR/Server in an environmental housing. http://www.oksolar.com/enclosures/Environmentally_controled_cabinet.htm http://www.pantrol.com/products/telecom/7.html http://www.gl.com/consulting_cabinetdesignletter.html http://www.purcellsystems.com/ecoflex/ http://www.mierproducts.com/outdoor_temperature-controlled_enclosures.html This is the company we use: http://www.ddbunlimited.com/

License Plate Capture Position and Recommendation
ssmith10pn replied to dahomes555's topic in System Design
You need a minimum of 45 to 50 pixels per foot. -
As the title says I need an outdoor housing that moves Left, Right, Up, Down, and rotates. Most housings I see just move left, right, up, and down.

Provided you have full access to the network. We build our own networks My biggest customer makes us ride his network with a unique VLAN. So I assume your doing 2 VLANs at the server? yours and theirs?

I do the final focus at dusk for 2 reasons. The Iris is wide open and the laptop screen is easy to see.

Q: Camera type (analog vs. IP) by location for residence?
ssmith10pn replied to ctbaker's topic in System Design
One thing to keep in mind when your doing a survey like this and taking pictures. Your point of view is looking at the camera instead of what the camera would be seeing. I try to take shots of what the camera will see. Not always easy but it helps. -
Exactly. I forgot all about the finger printing and back ground check.

I'll bet it's the white hand rail. Throw a tarp over the handrail and see what happens.

We are licensed for Access, and Alarms. CCTV hasn't become a requirement here yet. I wish it would. Gets rid of the Rif Raf.

I saw one like this today. Only it was a real speaker and I could not see the camera. http://www.supercircuits.com/Hidden-Cameras/Fixed-Covert-Cameras/COVSKSW

Pelco and Milestone - can they play nice?
ssmith10pn replied to UnderCover's topic in IP/Megapixel Cameras and Software Solutions
I havent use Avigilon, whats so good about it vs Milestone or Nice? Not to be disrespect able but you don't get out much do you? I always knew who Avigilon was. Because it was always in the spec and we didn't sell it. -
This leads me to wonder....How safe is the Microsoft Xbox Kinect? It uses IR and blasts you in the face with it, some people use the Kinect for 8 hours straight. Considering my recent experience I can tell you I won't be playing it. The naysayers seem to think if you're not blinded then it's okay. I consider any loss of vision a major, life-changing consequence that should be avoided. 7qLDzLYPG-w lqgNRVNzYmg I wonder what makes him think it's a Laser in the X Box? I would think it's nothing more than a LED.

I started playing with this and noticed a significant difference in bandwidth but I haven't noticed any real changes in playback quality. What are good rules of thumb for keyframe intervals vs image rate? I was at 5 ips with a keyframe interval of 2 and moved it to 10. I haven't noticed any difference in playback quality but it cut the bandwidth by almost 1/3. At an image rate of 5 and a keyframe rate of 10 that's a key frame every 2 seconds. Doing a google search it appears Apple Quicktime runs at about 3 seconds and ESPN streams at about 1 every 10 seconds with the exceptions of sending a key frame at scene changes. Since CCTV scenes don't change because the scene is static I wonder how far this could go? Opinions welcome!

H264 Keyframe intervals
ssmith10pn replied to ssmith10pn's topic in IP/Megapixel Cameras and Software Solutions
Reply from Avigilon, Hi Scott, This is something that can change from case to case, in general we might recommend to have 1 Key frame per second, so the interval will match the Frame Rate settings. Reason for this is because if by any external reason you lose one of the P frames, the system will need to re-sync in the next K frame and this will represent only losing < 1 sec of video. if this is not critical, you can increase the interval for a larger value. The impact in the bandwidth is more evident if the image have low levels of motion. If you increase the number of Key frames (reducing the interval) you are turning the H264 more Frame by Frame compression once you are sending more frames with the full image coding. It does not necessarily means more quality, as long as all frames are being received they should be able to allow the decompression to work properly and the playback quality will be very similar at human view. When the image have high motion, the P frames will be "almost" K once the image changed from the previous frame so you don't notice so much the bandwidth change. Another lead that could help you choosing the interval is the fact that when you are in playback and drag manually the red line over the timeline, the ACC Client will preview only the key frames, so if you have a larger value, you will see bigger jumps when manually moving the red line. You can refer to the "Understanding Compression Technologies for HD and Megapixel Surveillance" white paper for more detailed information. http://www.avigilon.com/products/documents/whitepapers/ -
H264 Keyframe intervals
ssmith10pn replied to ssmith10pn's topic in IP/Megapixel Cameras and Software Solutions
Must be a very solid network. I'll continue to watch it but with the Cameras set on 5IPS and the Keyframe Interval on 10 the playback is rock solid. Even on the cameras 22 miles away running over a AT&T fiber link back to the server. -
H264 Keyframe intervals
ssmith10pn replied to ssmith10pn's topic in IP/Megapixel Cameras and Software Solutions
Bandwidth is not an issue but every little bit helps on storage capacity. Just playing with a server that had twelve 4 channel Jpeg encoders, a hand full of 5mp jpeg 2000 cameras, (6) 2mp h264 cameras, and (10) h264 1mp cameras I cut the bandwith down from 190Mbps to 164Mbps just by changing the key frame from 2 to 10 on a 5ips setting. -

Even with Multicast 16 x 4 is a pretty good chunk. -
