    you know basicaly even entry level 1.3M IP cam will souck up all the pipeline and HDD space

     

    You are way over exaggerating bandwidth issues

     

    Do u so confident that?

     

     

    i think your getting a bit mixed up (remember dedicated network)

     

    Thanks Bro.

    Hello,

     

    As you stated you need upgrade analogue cctv to incoporated the IP system. I am wondering do you have experiecne to deal with the system.

     

    Becasue it is not easy even for old hand sometimes is dreads to face louse and complex enviroment. If you insist to do, you better consider HYbrid DVR which allow hook up both. There are some imperative thing you better to check ,one does the hybrid DVR compatible your IP cam( all will show compliance Brand list on official webiste). Second you have to assess how many bandwidth to gobble those video stream( you know basicaly even entry level 1.3M IP cam will souck up all the pipeline and HDD space).

     

    as above listed, you could estimate your mantain fee on those WAN to the telecom.If you point is based on remote via mobile device now most DVR is featued and you just set up functions you prefer to carry out. E.g. motion detector, event, ...

     

     

    You are way over exaggerating bandwidth issues

    Do u so confident that? Maybe you would say default lower resolution, if you do why should take Megapixel camera, you could estimate at least 10 units 1.3M to output 720P video stream. I know you are probably sales rep for some brand. Pls...

    The setup should be a piece of cake... I'll just use the Axis 240Q to bridge/present the 3 analog cameras. As to bandwidth, we have a 24 port Cisco PoE switch that shouldn't even flinch with a handful of cameras on it...

     

    I'm still uncertain on what cameras to use...

     

    Also - has anyone ever purchased a Dahua NVR? I see their DVR's (relabeled and otherwise) everywhere, but no info on their NVR's...

     

    Thx!

    I admire your courage, but yu must check the NVR or Hybrid fro verefy compliance IP barnd list. Or trust me you will .....

    Anti CR cures the problem in our warehouse.

    I will transfer to our engineer to see the how. By the way recently we have lauched some 600tvl, you could watch how those are the lin is below.

     

     

     

     

    i would get your engineers to look at cam 3 in your demo a camera acting like that will waste HD space if set to motion record

     

    Tank you sir I will check and infrom our staff to set up.

    It seems like Power problem.

     

    IR Cameras during night have more power consumption.

     

    Check the Voltage on the Camera. If It is lees than 11,5V you have the reason for this problem.

     

    Hello,

    I think you point probably right but if it lower supply to the IR lamp I think will be worst in image. becasue it will not effect britter and darker blends. Typically, camera is geared to more wide range for power supply as we do it even lower 11V would not be that.

     

    So maybe he could try ro switch his power supplier to proof it.

    The color rolling is caused by certain types of flourescent lights. Some camera DSP's, such as the Effio, has a feature called Anti CR which stands for Anti Color Rolling which takes care of the issue greatly. We have that issue in our warehouse with every single camera we test, its wierd.

     

    Hello Sean,

     

    As you mentioned ,effilo-e has the anti-cr. but it is not easy to clarify even the spec have default we still need to set all parameter, in some case, it will over explosure or some thing happens. Not all turnkey provide perfect solution and then we supplier just to do production.

     

    Because, we are now dedicated to developing effio-e board camera, and not so easy to dispose matching the function in perfectly.

     

    If posssible would you mind send me the shoot or link I will transfer to our engineer to see the how. By the way recently we have lauched some 600tvl, you could watch how those are the lin is below.

    Hello,

     

    It is called color rolling or breathing because you know when your power is supply DC and it will waves fllow up frequency(50Mhz or 60Mhz). Honest speaking it is normal situation but most clients feel it is correct status so now supplier will set up parameter to anti it happens( or lower it frequency).

     

    I think your light is florescent, sometimes you could trying to view via your DV, and find out. Or googing the clolor rolling...

    Hello.

     

    Now you are really facing nightmare and it is not esay to shoot. I agree with all opinion for take hybrid DVR if the client insist to plug IP cam (you better check the compliance brand list not all IP camera compatible even for milestone).

     

    If only equipped analog camera I think 5 pices is ok though 4M bandwidth and then pitch the data to the central room but you better looking for high calibre VMS with matrix function to project all video stream to TV wall. Of course if the boss needs to live monitoring via mobile deviceI think it is indespensable for investing to build up above 100M bandwidth to gobble those data.

    CCTV OVER BOUNDARY

    Hello

     

    Recently we have observed our neighbour sweeping windfall leaves into our back garden along with his own garden waste taking rubbish out of his bin and sweeping it over our boundary. They also cut the edge well over the boundary line, which over the years we have asked them not to do so and the last 3 years asked them in writing. The neighbour replies he cannot help it if their hedge cutters slips, and if we don’t like it take them to court.

    We have never seen eye-to-eye with these neighbours as we refuse to have our lives controlled by bullies over the years we have encountered verbal abuse harassment and much more, which the police have advised us to take a private prosecution. Also over the past 12 weeks we have had a total of £ 950.00 damage to our car which is parked on the road, we haven’t a clue who’s behind it we no the police cannot be everywhere.

    We have CCTV fitted, but no camera records-films past our boundary or on to the street.

     

    Could anyone please advise? We would come under English UK law.

     

    1) Can we record with our CCTV on to the public highway to film our car. As this rain of vandalism could last another year. We did ask the police but as normal less than helpful said we should ask a solicitor.

    2) Do I have the right to record our neighbours with CCTV them putting their rubbish over the boundary. I.e. recording over the boundary.

    3) I know we don’t fall under data protection as this is a normal house

     

    We have suffered from these neighbours for so many years now. Please if anyone as got some good advise we would be very grateful.

     

    Thanks

    Hello Hellen,

     

    It is really soap show, but I think points how to solve you pain.

     

    As for you concerned, I agree on all points from the guys, why not. All actions is base on protect your property and away from fear, I think even on court you would be fine.

     

    You could get some camera (better is IR bullet or IR Dome for outdoor use), one DVR and one modulator( which allow you monitoring via cable TV channel).

     

    I think you cloud get all stuff in some where.

    Hello,

     

    As for you concern, the enviroment in Theater stage, I am not sure how is it complicated lighting source.

     

    If it mix up neon and spot and some else it is not easy to overcome the abberation or inteferring.

     

    As you stated, now you own IR illuminator so you better take starlight typy camera it allow capture color clear picture in lowest lux.( better take 420tvl not 520tvl or above)

    I picked up one of these cameras from ebay a month or so ago.

     

    It is an alright camera. I have it in the default setting.

     

    When in 2.8 (wide) mode, at night when the IR's kick on, they create port hole effect, meaning there is a white circle surrounding the outter most portion of the monitor, (not a huge issue) but in nighttime ir setting, I don't think you are getting a full 2.8 because of the white circle blocking out some of the picture on the monitor. You'd be getting more like 3-4mm of actual viewing on the monitor.

     

    secondly, the camera is not a true day & night. it is electronic day & night. True day & night uses a mechanical IR cut filter (a servo motor physically moves a filter infront of the camera, to block IR in the daytime, and at night when the camera switches to black & white, the servo retracts the filter). That is what happens with a REAL TRUE day & night camera.

    This camera, uses electronic day & night. Meaning, the camera tries to adjust color during the daytime to compensate for the IR washout, and at night it switches over to black & white.

     

    I was a bit upset when the camera arrived and found that it was not true mechanical ir cut filter, when in the specs it is advertised as true day & night. Not a huge issue when it comes to picture quality, but it just upset me that it was advertised as being true day & night and when I got it I found that it was electronic day & night.

     

    Also, the housing is huge, leading the buyer to believe that there is some serious "meat & potatos" or "guts" when it comes to the camera, but the huge housing is all for show. I unscrewed the front of the camera, and it is nothing but a tiny board camera mounted inside a huge housing.

     

    Say the body of the camera is about 8 inches long (not including the mounting bracket). The board camera inside with IR illuminators are only about 2 inches deep. There is 6 inches of empty space of the camera body housing. The housing is made big to just give you a feeling that you are getting more for your money.

     

    Now on the other hand, I bought one of the 700tvl effio-e turret cameras (they advertised it in the title on eBay as a dome camera, but there is a difference between a dome and a turret style camera, this is technically a turret camera, not a dome camera), the turret looks like an eyeball & socket, where I'm sure you already know what a dome camera looks like. The 700tv turret cam that I bought on ebay was a fixed 3.6mm and I'm more pleased with that camera, than I am with the 700tvl effio-e 2.8-12mm bullet camera. Simply due to the fact that I didn't have to set the focal length or focus (the 3.6mm is set to a fixed 3.6mm and comes prefocused), plus the turret design is so simple to mount and aim. Plus it is a fraction of the size of the 2.8-12mm bullet that you are looking at, because as I mentioned above, the bullet camera is oversized just to give you a false feeling of you are getting more for your money, but I like the simplicity & compact design of the 700tvl effio-e turret camera, plus the fixed 3.6mm is a good general purpose wide field of view lens, and with it being prefocused, it is a easy installation.

     

    So right now I'm using a 4 channel DVR running 7.5fps full d1 every channel.

     

    I'm using a Cyberdome PTZ (just for fun)

    The other 3 cameras are

    1. CNB 3.6mm bullet cam (this cam is the generation before the mona lisa chipset came out), I got it new in the unopened box off eBay for like $15, it is 600tvl, it is nothing too fancy but it is a good little camera for the price that I paid.

    2. the 700tvl effio-e bullet (the same one you are inquiring about)

    3. the 700tvl effio-e turret - 3.6mm fixed lens, I really like this camera

     

    Right now I'm saving up for a Qvis Apollo HD 16 channel DVR to upgrade from my 4 channel dvr. Once I buy the Qvis DVR, for the other 12 channels, I'm going to experiment with one of the VCM-24VF CNB dome cameras that everyone talks alot about on here.

     

    I'd also like to try out one of the Samsung Dome or Bullet cameras, the bullet cams would be the SCO-2080, they also make a SCO-2080R which the R symbolizes that the camera has onboard IR illuminators, but I don't really care for onboard IR, due to bugs constantly flying around the camera because of the IR.

     

    I have played around with using seperate IR illuminators (cheap ones bought on eBay for about $10-15), they are a turret design, with about 48 ir leds. I prefer to position them several feet away from the camera pointing in the same direction as the camera. In the warmer months when the bugs are out in full strength, having the illuminators away from the cameras really cuts down on bugs flying in front of the camera at night. Cause the bugs are attracted to the ir illuminators, and since those are positioned several feet to the side of the camera, the bugs tend to cling around the ir illuminators and not get in front of the camera. I'm shooting no further than about 30-40 feet, and the cheap $10-15 turret illuminators on eBay do the job just fine. They are mounted up under the eve and although the illuminators are not waterproof, I wrapped the turret in a little bit of white duct tape and they have been running just fine outdoors. I just wouldn't go mounting them exposed without some type of overhead protection such as the eve. If you were to mount it to let say a pole with no overhead protection, the weather would kill the illuminator the first time it rained.

     

    Well anyway, I could go on and on, but this is my little (long) review of the effio cams along with some other information about my setup. Hopefully it helps someone as I have done countless hours of reading on here which really helped me to learn the in & outs of how to go about setting up my system. So if someone takes the time to read this and it helps them out, then I feel good knowing that I gave back a little to the community that helped me.

    Hi sir,

     

    you are a pro, as for you concern that is in parameter not good to programming. Sometimes youi know not onle assemble those key components to an tangible one item. It needs spent a long lengh time to adjust to verify which is best of breed in those default su as color temprature, white balance...

     

    And your another good shoot is real day & night certainly need ICR to filter all light. If you aaplicable in some project this will characterized the advange in the complicated enviroment.

     

    You are reallya veteran. " title="Applause" />
