    yes, you will need a router that supports Dynamic DNS, which most do these days. Unless the Dynamic DNS is builtin function to the DVR, which is most likely is not.

     

    You will need to do two things with the router:

    1. setup a port forward to connect the local IP address to port you will address from the browser (usually it is port 80)

     

    2. setup Dynamic DNS to connect to your Dynamic DNS provider

    Have wondered if the higher end DVRs have that much better picture quality. Such as: Sanyo, Panasonic, Bosch, ARM and Toshiba.

     

    They are pretty costly compared to the lower end, which is the type of customer I usually get.

     

    of the compression std's that are used, MPEG-4, H.264, and M-JPEG, does the quality of the DVR yield a much clearer recording ?

     

    What am I getting in a higher end DVR to justify $2k-$5k cost ??

     

    (assuming good cameras & lenses).

    Did you try taking out the battery ?

     

    The AverMedia support site said this...

     

    Please open the EB1004BAK casing and carefully remove the onboard battery. Wait about 10 minutes before putting the battery back again. This should reset the password to the factory default which is '111111'.

    the fan replacement worked, but I had to splice the wires from the old fan connector.

     

    now that I've gone through all this, I think the main problem is that vent holes in the case are too small and creates a lot of back pressure on the fan.

     

    an easy fix to this would be to drill out the holes to larger ones or just cut out that section. but then it gets ghetto looking and probably will void any warranty.

    the fan inside the Avermedia EB1304NET SATA is very hard to find.

     

    Avermedia doesn't sell it as a part, and searching for the exact replacement turned up nothing.

     

    So I am ordering a basic 3 wire 40x40x10mm fan and using the existing

    plug from the bad fan. hopefully that will work.

     

    The fan I ordered is Link Depot FAN-4010-B off amazon, in case someone is interested.

    I just installed the SATA version of the EB1304NET, and the cooling fan is making squealing noises just after running 1 week.

     

    I need to find where I can get a replacement fan. Anybody have any sources or part numbers for this fan ?

     

    The supplier said I'd have to send it in to Avermedia, but it's working fine and I don't want to bring down the DVR because of the fan.

    anybody know how this applies to condos and the common area? basically i am going to put 2-4 cameras in the windows (on the inside facing opposite directions) due to an slight increase in theft in the area since the economy is in the crapper. i might duplicate a couple views in a certain direction w/ a higher zoom lense since a couple catalytic converters have been ripped off costing the owners $600-$700 and i can see out to the parking lot from my condo. anything i need to do? or who to contact regarding this situation?

     

    i am not an expert, but as long as you are not recording audio, and not zooming in intentionally to someone's bedroom, then general surveillance to protect your property and belongings is within your rights.

     

    ask yourself the basic question, "Am I violating someone's privacy of their own home ?" if the answer is no, then you are probably in the clear.

    I think an IR Illuminator is all you need. The few cameras I have with built-in IR LEDs attract bugs which in turn attract spider webs in front of the camera which in turn are lit up by the IR. A separated IR light would prevent that.

     

     

    I have one of these on order now:

    yes I have had this problem too...with built in IR. spider webs and dried rain drops...cause a haze on the glass, reflecting the IR back into the camera and killing the view.

     

    separate IR illuminator is the way to go. Get the strongest you can afford.

    wondering if anyone had poor performance with Arecont 3100DN at night ?

     

    It seems that the Arecont sensor has poor IR response. I have a Tamron IR lens installed currently, also tried a Computar IR lens as well. Even with very strong IR lamps, I cannot get much illumination of the area.

     

    If I turn on the "moonlight" mode, the illumination is much better, however the exposure time is very long and pretty useless for anything moving.

     

    However with the IQinvision 752, the IR lamps light up the area with no problem. (LightGrabber is disabled). Adding even 1x LightGrabber gives much better illumination, without too much exposure time increase.

     

    Comparing both camera night images, the Arecont 3100DN is almost black, whereas the IQ 752 shows the same area quite clearly, without any IR lamps.

     

    Unless there is something wrong with the Arecont setup, I think this camera is not very good for night viewing. During the day it is fine, and has very clear images.

    But what Pc would you need to record(no live view) Arecont, 3 x Av1300, 15fps@ 1280x1024 each ?

     

    This is one thing I dont like about IP cameras, there is no standart way ot calculating tech spec

     

    also depends on whether you are doing motion detection in the s/w.

     

    that would require an estimate of how many hours there is motion, and the % detection of motion.

    hi,

     

    Looking to implement a system with OnSSI NetDVR with around 15 ip cams. 11 being 3 M pixel and 4 PTZ 640x480.

     

    This will be on it's own gigabit LAN. NVR pretty beefy Xeon 2.33 Ghz Dual Core, 4GB RAM, 1033 FSB, 3 TB disk space!

     

    Clients will connect by web access. There will be 1 monitor client on the LAN, but the rest will login via internet.

     

    My question is, how well can I expect the clients to work via web access ?

    assuming a high speed DSL or Cable connection with fixed IP.

     

    Is this going to be doggy ? they don't want the cameras to be on the company LAN.

     

    Any suggestions ? Anyone doing the same thing ?

     

    thanks for your comments..

    That would be great if you could set up both and provide day and night images from both

     

    they both have night integration modes, which are not that useful to me for capturing anything moving. They do work awesome for viewing in total darkness however, but because of the integrated frames, anything moving will be a blur.

     

    I will try to make comparisons with both night integration on and off.

    Initially I put a Computar 1/2 IR lens on the 3100DN but could not get a sharp focus in bright light with the iris wide open. So I had to close it down, but that killed the night vision. So now I have a Tamron Aspherical IR

     

    Can u tell us plz part number for Tamron ?

    Thx

     

    These are the ones I ordered:

    1/2" Aspherical IR 12VM412ASIR MANUAL IRIS 4-12MM

    1/2" Aspherical IR 12VM1040ASIR MANUAL IRIS 10-40MM

    Regarding day/night versions of Arecont. I was confused as well that they dont have auto iris support and dropped email to Arecont support which was replied as "Digital cameras dont need AI lenses as they digitally correct amount of light. Analog cameras cant do that, so they need auto iris to decrease bright sun for example. Auto Iris as fact will dissapear in next few years."

     

    To be honest, Arecont cameras are fantastic value for money at day time, but crap at night Picture quality is not that you would expect. Lot of noise, blurry moving objects. Haven`t tried IQinvision, but have heard that they are more better, so costing more as well.

     

    I usually use lot of light when installing Arecont DN cameras, as least 500w illuminator with motion detection sensor with Philips/Osram 2000h bulb. I think some years will go till megapixel cameras will start beating analog cameras at night.

     

     

    Also - doing all settings is quite painful thing. DO NOT try saving money on lense, Arecont ones are CRAP. Use Tamron, Fujinon or Computar.

     

    I have both Arecont 3100DN and IQinvision IP7152 (D/N)

     

    I will try to make a comparison of the night time performance, right now I have the Arecont out in the test area. I'll put up the IQinvision next.

     

    Initially I put a Computar 1/2 IR lens on the 3100DN but could not get a sharp focus in bright light with the iris wide open. So I had to close it down, but that killed the night vision. So now I have a Tamron Aspherical IR and that seems to work a lot better.

     

    The IQinvision camera has a lot of firmware controls for the user to tweak the image, where Arecont doesn't. Also the IQinvision lenses are pretty decent.
