cctv_down_under

I ahve never agreed it is important, I know all about it, I used to dsitribute many MIC and MIK products, there are many good manufactorers, look at Sunkwang for instance.....I am not saying the products aren't any good, more the way business is done, China is huge and many companies but perhaps other countries are not as big, you cant just SPAM out your product and expect respect of it...people here have been doing business for a long time and they buy of whom they can trust, you must get your rpodutc to trusted peopel to distribute your equipment. Asian Manufactorers in my experience concentrate more on volume than reputation, and you could achieve the same result only slower but it would be a lasting result.

I dont quite understand the English in that, can you perhaps make it slightly clearer as it is hard to understand.

You guys even buy cars from us now!

Ken, that is my whle point...if the silly MIK MIC manufactorers would only realise it is about supporting people in the country they want to to sell to buy giving them OEM product and remaining loyal, then the local consumer will buy with confidence...the problem is that the Manufactorers, dont know the market so they dont know who is good to sell to and who is just pretending to be big, so having a local rep would eliminate this issue...I cant understand how for $100k a year they could not make more money in each country

The problems are many for MIK MIC roducts, the biggets mistake made by MIC MIK companies is to try to increase volume too fast...this measn selling direct...., they try too hard to sell their product direct to countries who's market they do not undrstand, no larger systems integrator will ever buy from a company like that, because they do not want to compete directly. secondly it is your systems integrator that will be the person who gets the equipment specified by the consultant...this means; Say a new airport is to be built, well it needs to be consulted, the consultant will recommend equipment that the integrator recommends to them....Asian sources tend to flood their eqiepment ot every person available and system integrators then wont help them. When was the last time you bought somthing of someone who could barely speak english. The next point is loyalty, the asian market is famous for promising exclusive rights to products and then taking it away....they use companies to expose their name and then try to go direct. The other point is QA, qualtiy assurance is VERY poor in most MIK MIC manufactoring, this leads to failiure rates that are higher, it is one thing to have cheaper electronics to save money, but poorly assembled and tested products tend to come mostly from Asia. If only they spent money on employing representatives IN each country rather than spamming via email and broken english telephone calls, then the market share they wish to gain would be better served, they would not scare off the integrators, they could get thier gear recommended for major projects and they would knwo what price point to place their product, not to mention deal with someone who speaks English. I wish the major manufactorers had reps in each country, surely they waste that mushc money by not having them, and if nothing else it is cheap market research!

Just fly me over and I will do it for you

Just out of curiosity, how many registers are you trying to capture...if only one you may not need the box at all

I have to admit the Alltronix gear is great, it carries a life time warranty, we use the 32 and 16 way rackmounts and they have not failed us yet

I dont know anythign about GM, but it is possible the MOBO bios can not see that size drive, try a smaller sized drive and see if you get the same error

Dont you guys have any licensing restrictions there, can anyone do CCTV?

Anyone?

Here are some fun and lame ones...... Rig a tracking PTZ inside and set a reed switch on open circuit of your entry door to swing around and zoom in, have a nice montior in front of them as they walk in so that they can see themselves in full detail and have the PTZ follow them around the room....use the Geovision DVr to show motion detection on screen....and let them see the moving pixels...LOOKS PERTY!!! Then when they leave the office, rig an I/O module to a reed switch and have Geo play a "Thanks for shopping at wallmart" audio message as the door opens. Then point a camera at the wall so it can see nothing else and wire a DVD Player with all your promo garbage to the Geo I/O, let them use motion detection to wave their hand between the camera and the wall to start your demo. Get a doctors eye chart, make a small closet sized dark room and put the chart in there, put some cuoured peices of paper too, make them start to read the chart and then dim the lights by using a pressure switch on the floor to activate when they walk in to the closet, setting the dimmer to slow, when they cant read it anymore because it was so dark then tell them to stand outside and read it, they will ask how....show them the camera in the room and show how it can see better than the human eye...ask what colours they saw...when they cant remember them..tell them that would be about as much time as you would have in a robbery to id a shirt colour and show that the camera is still in colour in low light. Make a coffin box and put two CS mounts in it, get your competitors product and yours and put a barbie doll in the box, use a dim swicth to lower the light to do a comparison, build a frosted plate of glass behind barbie and place a bright bulb in it, show how backlight can affect an image. Take your DVR player to all suppliers and ask them to record your output of a small scene from a movie.....make it funny...pick something complex like a light intensive scene, ask them to provide you with the AVI file, collect many of the same and place them on your demo machine.....show the customer how good the others record. Park your car every day on top of a Vandal dome LOL

DOH!!!!!! Is the small one Samsung too? The cameras...anyone know?

http://www.videoman.com.au/whats_new.asp Intersted in knowing where the cameras and DVR's come from?

If Vlado goes, I'll come too...Id pay for an hour of his time to pick his brains...he is a genious!

What Company?

There are so many things to consider when doing licence plate recognition that it is often left well alone...here are some things that I have learned with it. 1/ Your camera will need to adjust shutter speeds on the fly and keep in mind that when doing this your light level exposure will change accordingly, also to avoid motion blur you need to be careful, if your shutter speed is too low then motion blur will occur on fast moving objects, and if set too high then you will need much more light, so having a camera that can adjust on the fly is imperitive. The best cameras can adjust shutter speed according to light level...IE it sets the best speed based on available light and when that light deteriorates then it will adjust the shutter in increments until it finds a balance. You will need at least 1/500 shutter speed to read the plate on a fast moving vehicle. 2/ The license plate characters must take up a minimum of at least 5% of the monitor height for display identification and for digital recording the plate must be a minimum of 30 pixels in height before you add compression. 3/ Recording resolution of your DVR will matter, because this can be the difference between being able to read the plate or not. 4/ Compression really counts, some compressions take objects of the same contour and texture and compress those pixels most, flat objects can often be overly compressed unless the contrast between character and plate can be amplified or inverted. 5/ You need a camera that can handle the bloom effect and vertical smear associated with headlights of vehicles 6/ Your going to need to set a peak level for white, so that it does not affect the range of your camera, IE a wide dynamic range camera with programmable mask will help. 7/ Zooming in from distance affects the Field of View, so getting closer really can help. 8/ Do not use much gain at night time, gain will amplify the brightness of the headlights, you will find that the best result will occur when you actually set the camera so low in gain and peak that the picture is almost black until a car goes past, the MOST common mistake is to park a car with headlights on and use that scene to get the setting right for a camera, you will inveriably try to allow for too much lighting to ID more than the plate, the lights from the car will definately light up enough for the plate to be seen so it is best to set all your settings to low. 9/ Full TV Frame recordings will not have an interlacing effect and therefore a good de-interlace must be used for fast objects if your DVR can not record a full frame. 10/ Remember that light reflects and that angle is critical, remember also that asphalt has little to no, scene reflectance.

I tottaly agree Rory, it is not a finished product yet becasue of price point, however it will get cheaper as you rightly pointed out, quite obviously no camera can see around corners but quite rightly as well a lot of times you can take advantage of the resolution.....one example would be a cash register, how many times do we say that you can see the notes....OR...the customers and products and not both...or an Entry camera that is zoomed in......I am not saying it is ready now, just that it is obvious we will be heading down this path, the resolutions are growing and using stitching technologies and mirror optics allows for multiple Meag Pixel cameras to be enclosed in one unit. I guess down the track we will have no need of a DVR, just massive storage, quite simply compression will be at the camera and each cam will see as much as it can without obstruction...our design will be simple becasue we will simply find a point on the wall that can be seen from many points...IE walk around and see if you can still see that point...every time you can see that point on the wall you will be able to cover that area...we will simply apply a blanket approach to large areas and then one larger image will become several cameras with several IP's. Prices will fall because their is less of a need of hardware and the same technology is driven for consumer electronics...be prepared to see people like Cannon and others agressively enter the CCTV market... it would seem that big companies that sell consumer photograpy products will be entering the arena heavily. IP mega cams will become mainstream within 4 or 5 years, there is simply no reason that they will not become affordable...better start learning IP a lot more ..me thinks I know of one company in particular that s about to release Mega Pixel cams for the firts time with this zoning and IP approach, they are scheduled for release early next year!

Ultimately, we will all be using Mega Pixel cameras soon, the only limitation is just how to you transport the bandwidth and how do you view it...for example. A large 20 Megapixel cctv camera image is huge and you would need to scroll around the image to find the info you want, this is fine after the fact but not so fine for live viewing...so the problem is...... Imagine viewing an entire carpark of 400 cars, quite easy to do with a huge megapixel camera, but can you see the guy in the corner breaking into a car because the gate was left open or can you see the girl getting harrased on the walkway....well yes you can but only if you go back to have a look becasue it is far too much to view in one image. The latest products I have seen are truley amazing... they take one very large 20 - 30 Megapixel image of a large area, you then mark the areas of interest on that huge image...IE entry gate, walkway etc by drwaing a box around it and zooming into that point...that box becomes a camera.... to explain more simply imagine this. 1 x Huge image from 1 camera becomes 10 camera views that are zoomed in, the effect is that you now have 10 cameras that can be viewed individually on the screen at once, the remainder of the unused areas is still recorded but each box or camera zoom has its own zoom point and indeed its own IP address...it is truley amazing and it works out fairly cheap for unobstructed views!

Firstly make sure that your camera has the cut filter or you may be wasting your time....I suggest a seperate device...makes for easier servicing and aiming the UF range are really good

Only problem with that is you are limited to controlling the PTZ's through Geo software, not on a keyboard controller, why not just use a 485 ---> Ethernet Converter at one end and a Ethernet ---> 485 converter at the other. Or use a 485 ---> Fibre Coverter at the DVR end and then convert back from Fibre ----> 485 at the other. This way if you ever change from Geo, you can still control the PTZ via the keyboard. Depending on the PTZ type you could use a webserver that has that inbuilt protocol.

View or Distribute, if only view, then you may be able to find a RF modulator down there, otherwise is their any Fibre or Spare Telco

In Geovision you can test your live viewing with what is being recorded and compare the file size I think from memory it is under the advanced section of video source... Interlace rendering is done by the video card and your card must support it...if not it is a waste of time, the interlace occurs becasue the chips are manufactured to support both PAL and NTSC and they are diuffernt shapes, so interlacing effect happens ... get a good quality video card that handles hardware overlay and rendering adn then anabel the interlace

have to agree with this unless of course you arent in the US The AVtech product is about the best price point for these kind of jobs it depends on how your business is set up IE if you want to sell a standalone you need less support so perhaps moving away from PCI cards is better...but if you have the ability to provide support then PCI cards are good and the best value is indeed Aver or Geo No US is more expensive but better quality control i would not use these unless you are aware of the inherrant support risks I would recommend Dedicated Micros if your budget supports it as this is UK based, if Vudget is an issue then AVtech or Nadatel, and if you want real quality then the GE range or Pansonic or Bosch would be your best standalone device
