Hey guys, Does anyone know if the latest firmware from Dahua for one of their 1-2MP IP cameras is now ONVIF 2.0 or Profile S compliant ?

Just curious if someone has experience in how to calculate how much bandwidth a processor can handle for IP cameras. If i use an i3 4th gen processor with like 8gb ram would it handle 30-40Mbps of bandwidth being thrown at it from some ip cameras or would it take an i5.. just trying to not overload a small server for 6-8 , 1-2megapixel cameras. thx.

thanks for the quick feedback! i'm looking at just building my own small server box for my house and residential neighbors and expecting the viewing to be done on regular laptop or pc in the home... I'd definitely want the cameras to support the motion detection and not the server. so, it sounds like i'd be safe with an i5 4th gen and 8gb ram then a 7200rpm storage and a handful of 1-2MP cameras. Just trying to build a low cost server box for like $500-$600. you guys rock on this board.

If i had to choose between just those two options it would be the axis for the lightfinder tech. however, have you looked at the Avigilon Bullet cameras? It's a great camera for nighttime use with built in patented adaptive IR. Meaning it will adjust the IR strength based on the histogram of the view as well as the focus of the IR depending on it if you are zoomed out or zoomed in (optically) for your fov. 1.0-H3-B01-IR for a 1MP outdoor ready bullet 3-9mm lens IP camera 2.0-H3-B01-IR for a 2MP outdoor ready bullet 3-9mm lens IP camera. throw their ENC-4P-H264 4port encoder (requires only one license) to bring up to 4 analog cameras into the system Use a desktop computer for a server like an i3-i5 processor, memory, storage and you are good to go.. and license keys to use the software. Avigilon is very easy to use and what you see live is what you'll get recorded with lossless recording. keyword avigilon bullet on youtube for some sample video. cliff

Morning, Looking to put in 3-4 wireless G or N VGA to 2MP cameras in a house and use the Avigilon VMS. What are you guys seeing or recommending out there for wireless solutions that don't cost to much. I know there is the Axis-1033W/34W which is natively supported but it's also $260-$330 roughly. There is also the D-Link DCS-932L VGA camera where you could do generic rtsp and probably could pick up for $50-$100. Anything else out there you might recommend. Wired cameras i know you could get some inexpensive analogs + encoder or I even saw a Dahua 1.3mp IP onvif camera in Avigilon and it was like i think $160 roughly. Or any other home residential designs out there using Avigilon? I'm thinking just an i5 or i7 server would be just fine as well. thanks, cliff

Ethernet Cat 5/ 5e cabling is rated up to 330' if you go past that without another switch to repeat the signal another 330' then you might have packet loss in your video. Also, is any of the cabling run outside or all inside cabling. Fiber Optic is great for long distances or to limit interference. There are companies that make a copper to fiber converter with PoE if we are talking IP Cameras. Or there are companies that make ethernet extenders which will help push the signal farther for runs past the 330' limitation. just some thoughts.

Avigilon does it. What you see live is what you get recorded.

I agree, i've heard good things with the ubiquiti wireless product. What i would suggest is don't focus on a wireless IP Camera -- get a WIRED IP camera that meets your specifications and use an actual wireless access point to send your video. Access points have the option for stronger antennas to boost your signal where as a wireless camera usually has like a little 2dbi rubber duck antenna.. not very good for going 200-300' or so.

I know you are trying to stay in a budget.. but ask the school powers at be - how much is it going to cost if a parent sues the school because of a claim they are making about their child getting hurt and the analog video or ip video that's recording at a lower resolution (based on s/w or dvr they are using) can not show clear evidence that it's not the schools fault. You spend $1k or 3k on a system and the school ends up having to settle with a parent for $20k or higher and insurance costs go up because of the incident. then was it worth the $1k-3k on a system. If you want to do it right you really need to look at every scene that you want a camera on, use a lens calculator tool to figure out how much pixel density you need to be able to give a good clear shot. example - the playground is 50' from the building where the camera will be and it's 40' feet wide and mounted 10' high. A 1mp camera will give you roughly 30pixels per foot resolution at the 50' distance or better the close you are to the camera. A 2mp camera will give you roughly 50pixels per foot which is enough to make out facial details and a clear image at 50' goto an analog and you are probably down to 20pixels.. cost difference between a 1mp and a 2mp camera is usually around $130 difference maybe. So, again - go through each of your scenes and decide how much clarity do i need at the farthest distance and pick a software platform that does lossless recording... if you buy a 2mp camera you want to record 2mp worth of video not have it compress down to a D1 720x480 resolution because then you lose quality. just my thoughts

I agree.. having a workstation server at the remote building is better for recording then send the video to the client via wireless or a trenched wire.. Also, if you have to go wireless I would look at not using a wireless camera but instead use a wired camera plugged into a wireless access point which then will send your streams back to the head end.. places to look for low cost wireless solution would be like Ubiquiti's bullet m series or maybe d-link's dap-3520.. You could put access points at remote buildings wired into a switch which the cameras would be plugged into, then with directional antennas on those point to the headend building that has an access point with an omnidirectional antenna to receive the signals from the remote buildings. You also need to make sure you have line of sight with wireless.. no huge trees, hills or structures in the way of the wireless signal.

Honestly I think you have to ask yourself - how much is it going to cost me in insurance premiums or insurance claims because someone sued for something surveillance might have been able to discredit. I see news stories all the time like man robs store and steals $50k in products but yet was only protected with a $1k analog solution. Also not to mention bringing justice for an individual that has caused harm to someone in your store because of a robbery. Make sure to get a lossless recording ip solution so what you see live is what you see recorded which is not the case with DVR's which usually compress the images down to a lower resolution then what was live so the quality is even less. I would suggest 1 or 2mp IP cameras, maybe a 2 or 3mp outside (again i have no idea what your store is like just guessing here).. You are probably looking at around $5500 for 1-2 MP cameras x 8 of them including software licenses by someone, then another $1-2k for a workstation server.. again this is just ballpark guessing and just to give you a rough idea. But again, is it worth the $6k to be able to make faces out, identifiable marks on a person and/or save your self from false claims. just my .02 cliff

Morning guys new to the boards and had a curious question - I have an application where i want to use some 3 or 5mp cameras and still deciding on the software to use but was curious will all of the software packs like Genetec, Exacq, Milestone, Onssi, or Pelco record the full capabilities of my 3 or 5mp camera and capture all the pixels or will they dumb it down to like 4CIF or something on playback? Thanks and great forums here. -cliff
