yeh its confusing -- the little light though tells you if your in alt or not

Sorry soundy - perhapps it was - just tired of the ONLY IP approach - i wouldnt use a DVR for voip - they simply are not designed for it - besides you really want to set QOS before doing this and thats a lot easier with a voip router

This is what we look for 1/ Support - it must be available easily and in many time zones 2/ Development - the manufactorer must be spending money on improving its products 3/ Stock availability - they have to HOLD stock in each state and territory 4/ Warranty - minimum 3yrs 5/ Product Lifecycle support - available support/parts/replacements for years after product is ended 6/ Technical resource web portal - easy access to manuals/pricing/demos/spec sheets through a web portal 7/ Credit terms - having millions in recievables means the longer and larger your credit terms are with the supplier the better. 8/ Ease of install - time is money so the easier the product to support and install the better 9/ Commitment to advertising - no point selling a product that a manufactorer isnt advertising with media and marketing collateral 10/ Returns policy - advanced replacement is great 11/ Sales History - being able to get accurate info from the manufactorers crm package to work out delivery times etc. 12/ High credit limit - if a project is over 1mill then you need the supplier to be able to accept that cost for you rather than make you pay it up front. 13/ Support in many countries - important if you win work for multi national companies 14/ Technical sales people - very handy for presentations 15/ A and E specs - technical data for consultants to specify your products with I cant think of many more but the biggies are the account, the stock, the support....not the price

The above post is correct, use a powered USB extender - you can then join good quality USB extensions (5 meters each) - at the end put the powerred extender and your bluetooth reciever, if you also want control upstairs and your DVR has 2 x USB inputs just do the same for the second mouse - however if what they ahve done for you is feed your cameras into a RF modulator (IE 1 x camera per tv channel) then this is differnt because your not seeing the video from your DVr your seeing it BEFORE it gets to your DVR - if this is the case you need to take your normal DVR output and feed it also ino the RF Modulator

Could be a load of things, but most likely they have activated the second screen input - the Divar can do multiple screens - so its possible they are trying to use a screen that is not connected, its akin to switching to AV2 - you willbe able to tell by where the yellow light is and what line it is on. Try pressing the different montior screens and see what happens

What a load of GARBAGE. A lot of products have this feature - even Geovision - you could also just use a voip sender or audio encoder/reciever - it really depends on how you want it to work...IE Just a message in text - windows live Audio speaking directly - DVR Geovision or many other options Answer the message like a telephone call - windows live messenger There are plenty of options available - you cold use simple vooip to voip phones and set to auto answer

This corruption is common - and is why the database recovery tool was made - I doubt your running your system on a UPS that shuts down the DVR - this is CRITICAL - the video is first stored in memory before a closed file is created and if not shut down correcty it dumps this invomplete file onto the HDD - hence a corrupted video. The issue then becomes that the file index says - ok write to HDD, but HDD syas "cant write there" ..so OS syas..ok then write to next block and HDD says "cant write there" oever and over again until it has skipped that part of the HDD. Its not really an issue of a bad sector - more an area that the software can not recognise the size of the incomplete file.....for example sometimes when you download a bit torrent you get parts of a file, but until the file is complete it cant be played. The fix is simple - you will usually see that ONLY 1 x file is in each corrupt folder - so go to cam1 folder then open it - then change your view to "thumbnail view" - at this point you should know which folders are corrupt anyhow becasue they will be massively out fo file sequence ie all folders will be named as dates and some will be out of sequence - a long time ago - by switching to thumbnail view you are getting an auto preview of what is in the folder - however if the file in the folder is not able to be auto previewed then it is normally corrupted and you can simply remove these folders and runt he database repair tool. To avoid this buy a UPS that has the ability to shutdown windows and the Geo program - TBH you only need a basic script to stop geo then most UPS mobs have the ability to shut down any windows box. This will stop the ram dumping files to your HDD that are corrupted. Hope this helps Aussie Lad!

Same - Same - what do you need to know

I dont want to start "Flame wars" - but that kind of comment really annoys me - I hate the comparison made by almost all IP MP manufactorers that a single IP MP cam can replace many...thats PURE RUBBISH. For example - lets even use a simple example - where MP is supposed to be better.....and lets explode the myths. Imagine I have a warehouse with a south entry door and a north exit door (or a huge open area) the theory goes that because the area is large or open that I can use 1 x MP camera instead of 2 x Analogue. However if I mount the MP camera above the south door entry and point towards the north exit door to cover the entire area then if a person walks from south to north, i geta lovely high res shot of the back of their head - why because I removed a camera and used 1 where i should have used 2. Next - The colour of most warehouses is well....asphalt and non reflective - IP cameras as a rule do not handle low scene reflectance where minimal light is bounced to the camera so this means that in darker parts of the day or when lights are off the IP camera is not as light sensitive. Next - The north door is a roller door where deliveries come through and in the afternoon the sun shines in this doorway - well IP cameras as a rule generally do not have as wide a dynamic range as analogue cameras can have and therefore it is not going to handle the light difference as well. Next - During the day deliveries come in the North Doorway - but they usually happen around the same time as the sun is affecting the doorway in the aftternoon, I can see the delivery but can not tell who delivered the goods because their face is veiled in shade due to BLC not being as good as an analogue camera. Look I am being petty but also factual - god damn sick to death of all the spruting that happens from IP mobs......Aricont is amazing gear and has its purposes - so does Mobotix but soooooooooo sick of the sales hype. You should also mention that Aricont can do a massive resolution, hence why their lens may be more expensive..I have seen a demo in an airport where we could read the time of departure on message boards ages away in the picture, however out of the 500 people it took a picture of, 40% were facing the other way, so is 1 x camera and 1 x angle really a solution - I think not. I have used the strongest example available to IP MP cams - not the weakest, Imagine a grocery store with 15 aisles, whats the point of an IP MP camera then - after all if I put them on one side of an aisle they cant see the other side can they - so in reality 1 x camera per aisle is still needed. Dont get sucked into the hype lads!!!!

Well that narrows it down a lot.... You ahve eliminated the folowing; Cameras at site - because Zune didnt work either Power supply at site - Zune didnt work Cabling at site - Zune didnt work Earth loop - zune didnt work Geo Card - Tried in another machine and worked DVR power supply (for the pc) - Tried another one same problem So inreality that only leaves - software set up, video standard or PC ahrdware (other than the PC power supply) - I dont think it will take long now to work it out just try replacing components one at a time after a fresh install and amke sure you have the correct video standard - I am now thnking MOBO or Videocard but was SURE it was PC powersupply

I would imagine you would also see a clour bleed if it was the wrong standard - i dont think you can chage the standard after install can you? I still think its the DVR Power supply causing interference or a video card with power right next to the capture card. NTSC - PAL makes sensse but I have seen this before where a DVR powersupply becomes unshielded or un earthed. PS when you plugged in the Zune - did you remove all other cameras - this is important as one bad signal could affect the entire card?

that really looks more like gorund potential issue or interference than software issue...if your sure it works ok on an analogue input then what i would look for is this - can you connect a different power supply for the PC, some PC Powersupplies can become unshielded - and if they are too close to the card this can be an issue - but that is rather rare - to be honest my bets would have been the powersupply for the cameras or some wiring running near power near the DVR - the fact that it is on every channel says that either the card is affected or the cables all come in to the DVR near mains power - but like I said I have seen this exact same thing with an unshielded internal pc power supply.....does the cord have an earth?

PM me the LTC number and I will chase a manual for you

Thats too funny - What I meant though is you can strip down what most DVR's do in the export process....Ie there is usually just acodec needed for their file to be played in Windows Media Player (assuming that extension is supported) - so you just create a batch file to first detect codec - if not there install it - then launch windows media player (havent seen many pc's without it) and play the root directory of the cd. This means no crappy player to use......just simple WMP but beware with playspeeds. This is only going to work with DVR's that support native formats - but here is a Suga load of these around

Just found this quick and fast http://global.dymo.com/enAU/ProductAccessories/RHINO_101_-_for_wire_and_cable_marking.html?products=RHINO_101_-_for_wire_and_cable_marking

Iteresting though that they say will only work on some Thin Jacketed RG59 cable and would be annoying having to swap cartridge all the time....IE Mark Camera 1's RG59 then change to small Guage for Figure 8 Input 1. Other point is that my standard Dymo labeller costs $20 per site - the rybon is hugely expensive

Could you be a little bit more specific

I dont know that Model number anymore - however Bosch PTZ cameras run on a protocol called Bi-Phase wehn in this mode by default it menas they can be run with a 232/485 conversion with Bosch Equipment or any DVR that supports this protocol - the older versions needed you to instal an inline resitor at the end of line. One of the interesting things about Bosch PTZ's is that they can also run on Bilinx - this measn they can run and be controlled over the coax without the need for any data wire at all - you imply need the Bilinx tool. Almost all of the latest Bosch PTZ's are switchable to Pelco protocol via dip switches in the unit. I am not sure if this site still exists but it did once and it should have all the info you need - if not the Bosch site alwyas has manuals etc. http://www.autodome.com

Could also be the power supply - enough herbs t power it at start but once spinning the HDD then not enough - perhaps the PSU inside the machine is on its way out

It is pretty interesting to note that Sanyo are now ONLY producing HD cams - all new models will be High Def - they have released 9x new HD cameras all at full frame rate - thats a big commitment and IMHO a risk but if it leads them to having the most experience then good on them

Dont quote me but I am pretty sure some of the Sanyo recorders export in MPEG2 - but is this in a format that can autorun in a standard DVD player - I doubt it - a LOT of newer systems will copy an autorun file onto the DVD as well as their video, IE once you pop the DVD you burned into another pc it will auto detect the codec and if not there it will install it - this could even be made as a simple batch file really - we do this with some of the March Networks DVR's we sell - in this way the codec gets loaded in the background so they have no issue - but I do see your point - the issue is that unless your a casino you dont want to have MPEG2 as the native format as it is too large - so that means transcoding it and that takes a lot of resource to do

Howdy guys - it has been a while I keep coming up against this camera with the opposition saying that it leaves no dead spots around tills etc - has anyone got any feedback positive or negative?

Actually the shorter range ones arent that bad....check this out though..wanna see the moon from a PTZ http://video.boschsecurity.us/avc-view.aspx?videoid=152&categoryid=0 Or in the case of our Marine Mate http://video.boschsecurity.us/avc-view.aspx?videoid=148&categoryid=0 Or http://video.boschsecurity.us/avc-view.aspx?videoid=154&categoryid=0

That is a very big question to ask as it depends on so many other factors - generally Sony are better with low light performance depending on the grade of the chip and the type - a popular type (not grade) of Sony Chip is the Super Had - the reson it differs is that the tiny pixels in the CCD itself are curved, this allows more light to fall on the ccd....Imagine it like this ....take a square white sheet (CCD) of paper and put 50 sugar cubes on it (square pixels) when you shine a torch on it from an agle, the sharp top edges of the cubes cast shadows blocking the light from the next pixel - if those cubes were rounded then more light lands on the CCD - there is a lot more to the technology than this and as correctly mentioned above this is not the MAIN consideration, becasue if you havea good CCD and lousy electronics to cater for the signal then it can be worse IMHO Sony make beter chips than Sharp and Sony do not release their best chips to other manufactorers - that said I think neither are leaders in the market there are plenty that are mush better

If you are happy with B/W cameras then these are the best low light perfomance bang for buck, your budget is too small, its a complicated topic when telling you about low light performance as it depends on so many factors - all f which are generally fudged in the industry... You need to know what the Lux Rating in Color and B/W is, what size the F Stop of the lens was used for this measurement - was it measured at 50 or 100 IRE - was an aspherical Lens used - what was the transmition factor of the lens - was the measurement made at the target or the camera (scene illumination or reflected) - what was the scene reflectance factor of the environment......does the camera have an IR cut filter etc etc etc I know this seems a lot like garbage but it is not and it is why a lot of people only buy name branded cameras and lenses. The short answer is find a low lux camera (b/w is better) check that the fstop on the spec matches the lens that you can afford to buy, if you buy colour get a IR Cut filter camera and use an aspherical IR corrected lens
