    I was just messing with the WDR camera and the default WDR settings on those really does suck.

    I might end up with going close to the door and just using BLC anyway.

    But it does have impressive BLC.

    Will get some snapshots once its online etc.

    This is 47 difficult camera locations though so .. cant say it will be right away.

    I just installed 2 of those domes in a store ..

    It was actually the blue-i with blc .. instead of WDR, not the monalisa.

    gonna test the WDR again at this location, maybe it will differ, or not.

    Either way, used it because at least I know it works in one mode or the other, and its cheap.

    LOL ..

    Ive seen a new cashier in a gas station, surrounded by clearly visible cameras in the cash area, stealing over $700 on her first day ... then try tell the cops she didnt do it ...

    It goes to show you what is wrong with our system. Your honor, I don't know how he ended up with all dem holes. My gun musta misfired and he just kept falling on it. Judges question " why did he have 15 holes in his body" ... I guess he kept reloading it too.In all fairness, the home owner will always be the victim.

     

    here the cops tell you cold to drag them back inside the house.

    they got no pity for burglars here, especially as most shoot the victims dead now.

    its legal to kill someone in your house here as long as you feel threatened.

    although guns are illegal, only can get a license for hunting ...

    but the law says you can use anything at your disposal to defend yourself.

    Correct... But could someones financial circumstance push them to actions they might not otherwise do?

     

    Example: Steel food from a store because they have no money.

     

    If so, how can the statement "Poverty doesn't cause crime" be true?

     

    simply being poor does NOT make one a criminal.

     

    Absolutely not.

    Either one is a criminal or they are not, rich or poor.

    I lived out of my car at one point, and I never even considered stealing.

    Went without food many days, and yet did not steal.

    Haitians here are some of the most poverty stricken people in the world, yet they dont steal.

    If you were to ask a thief why they steal, I bet you will find its for reasons other than food.

    If you're using Cat5 and baluns, go with one of these: http://www.easterncctv.com/accessories/ev04p-vps.htm

    Do you know how much current they supply and to what distance?

    Eg. if using 12VDC 550ma cameras.

    Should be no different than any other 12VDC power source - it's 12V regulated output, so distance all depends on the cameras and how much loss they can handle. The jacks use three pairs for power by default, so you get the max range possible - specs page says up to 750'.

     

    The first site we used them, they added another camera to an area we didn't have a wire, so we split off a pair from the next closest camera... probably close to 150' to the first camera and another 50' to the second, both running over only two pairs. Both CNB VCM-24VFs, rated about 250mA at 12VDC, so that would be a total of around 500mA, and they're running no problem (then again, those cameras will also work all the way down to 10V or so).

    What I meant is how well can it send 550ma 12VDC over that cat5 at a distance?

    lets say the distances range from 65 feet to 150 feet.

     

    Say I have 3x 550ma cameras, and 1x350ma camera (all IR)

     

    I need to run new cables on a job - choice is a cat5 4 way balun and try power them all with that cat5, or run all RG59 - if im to run 18awg i may as well run RG59 one time, less connections and superior cable for security in this case (stronger for non conduit run, client will not pay for conduit so its run loose and tie strapped in open warehouse).

     

    Lets forget the strength of the cable for a minute, but can that cat5 24 awg hold enough power for those cameras at that current draw - if that is the real current draw - may be more as these are OEM cameras. How does this device get past the normal limitation of that kind of thing - I seriously want to know if it will save me work and money in the future. I dont want to hear about use non IR cameras because that is NOT an option.

     

    Thanks bro

    Dahua has client software and supports MAC also.

    Last time I checked TVT only has browser activeX.

    Otherwise I dont know the other differences as I dont use TVT.

     

    There are however MANY similar brands in China now and many use the same boards, chips, and their SDKs are near identical except minus the number of routines dahua give us -how far they go with programming, features, network/wan/mobile support really puts Dahua out above the rest. Dahua's tech support is great also.

    That could get quite annoying though.

    As video motion from a CCTV system could be going off every few seconds depending on the system, location, weather, time of day etc.

    And if they are trying to watch TV .. well

    you don't have to mess with working coax into tight spots (you cannot bend it too much).

    I have no issues with that. Fit RG59 (siamese) in a 1/2" crack between 2 beams above a camera today, joining the camera connections. Had to bend it almost completely to fit it snug and works like a champ - in fact we have it run between the cracks of the iron beams where they meet the ceiling, cant even see it. It can be heavy to pull especially when dealing with dozens of wires, but at least its strong cable - cat5 just seems so flimsy. IMO cat5 or better yet UTP multipair is best suited for multiple building apps and long runs.

    Im primarily a developer not just an end user, so Im comfortable working with anything someone throws my way - however, I have not used any central station software like that. Most just stream the video for themselves, and clients connect direct to the DVRs separately (I also do work for alarm central stations here, and have assisted the alarm central station software programmers in the past).

     

    That said, far be it for me to mention something I have briefly tested before, but here goes, you could look into a program called DSS from Dahua, its enterprise software for their DVRs. Client connects to the DSS server instead of the DVR - though I am not sure if it still streams from the DVR or not, as I didnt test it extensively due to time constraints.
