Gustavo
Basically what kind of device (camera, slr,camcorder etc) one thats up to date with HD and all that good stuff. Short films for school/youtube and good sound as well. Forums online get too crazy and I know alot has to do with preference but I would just like some suggestions on the types of devices I should be looking for.

HD camcorders interpolate the video, which means of every 25 frames of video, 4 or 5 frames are taken by the lens assembly; the other frames in between these are filled in by the camcorder inner circuitry, thus giving you not true video. It looks like this -one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, from front to back of the video. Near impossible to edit, even when you have the Multi port processor computer with the big 1GB Graphics card and a Sound card that is required to edit, view, watch and work with the files these camcorders produce.
Consumer level HD camcorders have 4 problems. 1) Blurry, fuzzy, out of focus areas closely around people in videos taken by consumer level HD camcorders. 2) Any movement, even a wave or lifting an arm, while in front of a recording consumer level HD camcorder, results in screen ghosts and artifacts being left on the video track, following the movement. Makes for bad video, sports videos are unwatchable. 3) These Consumer level HD camcorders all have a habit of the transferred to computer files are something you need to convert, thus losing your HD quality, to work with your editing software. 4) Mandatory maximum record times - 1 hour, 30 minutes, 8 minutes, 3 minutes – four different times advertised as maximum record time for some consumer level HD camcorders. No event I have ever been to is that short. Either take multiple camcorders or pack up with out getting the end of the event on video.
MiniDV is currently the most popular format for consumer digital camcorders. MiniDV camcorders are typically more affordable than their HDD and DVD counterparts. Each MiniDV tape will typically hold an hour of footage at normal recording speed and quality. MiniDV tapes are available for purchase at not only electronic and camera stores, but also at drugs stores and grocery stores, making them easy to find while your on vacation. There are literally hundreds of MiniDV camcorders available; both in standard and high-definition. And add the fact that to get a HD camcorder that could produce better video quality footage, one would have to spend in excess of $3500 for that camcorder that could produce higher quality video.

Can you really be 'caught' on recorded surveillance camera footage?
Horny Goat
If cameras weren't supervised live, only recorded. And you find out that some inventory was missing, say $1000's worth. Would it make since to hire someone to go back and review the recordings? For example, you hire someone at $10/hr, to check out 3 month's worth of video. 3 Month's worth is about (12 hr days x 6 cameras x 7 days a week x 4 weeks x 3 months = ) 6048hrs worth of footage. Let's say that the footage is viewed 4x speed, that would still leave 1512 hrs of tapes to observe, that's 1512hrs x $10/hr = $15,120. Even half of that would be $7560! With this in mind, would it make since for a retailer to investigate their loss? Because at places like Best Buy, Costco, and Sam's Club, your receipt will get checked - which in my opinion is the most effective and economical theft deterent. At other places like the newly understaffed Circuit City only seems to be some employees, recording cameras, and an unguarded door, which I think is a haven for crooks. Your thoughts?
Answer
If the film is digital, then a computer can analyse the recordings. There are several ways to do this.
What you are looking for is when the inventory in question gets moved by anyone. You are not interested in people walking past the inventory, or taking inventory other than what is missing.
One computer program can compare one frame to the next frame ... if identical, because no one there, and nothing moved, then you are not interested ... only when one frame is different from the next, are you interested ... the computer copies what changed, to another tape ... now what needs human review is dramatically reduced, puls you have highlighted human actions only with the missing inventory.
With this and other techniques the computer can fast forward at 100x speed through the parts of the footage where nothing relevant happening.
This leaves you footage where people moved the inventory in question, in which some of it may have been legitimate ... maybe there was $ 4,500.00 worth of inventory with $ 1,000.00 missing meaning that $ 3,500.00 was legally moved.
There's all kinds of crooked possibilities.
Customers come into a store ... they see one product with price tag of $ 50.00 & another with price tag of $ 40.00, they switch tags & buy the $ 50.00 item for $ 40.00 ... the more similar the products appear to be, the more difficult it is to detect this.
The poster about the gas station reminds me ... the gas station convenience store people are constantly changing the prices on the pumps. Some customers have figured out how to do this ... they drive up to the pump, the price is $ 3.50 a gallon ... they fiddle with the dials ... the price is nos $ 1.50 a gallon ... they buy 10 gallons at that price. A string of other people buy at that price. No one tells the store keeper that there's a bargain here.
Some of the biggest financial crimes have been by sub contractors ... the retail store gets some other company to come in to take inventory, or do an audit, or install some cameras, or whatever, and the other company has employees with sticky fingers, or who are careless about computer security.
There was a union at one of these places, whose membership knew how the retailer ordered inventory, and they found a way to cause the retailer inventory records to get erased. They did this at the same time as going out on strike.
It would be inappropriate in this forum to spell out in detail how the various crimes can be done & how to deter them, because then some crooks might get ideas they do not already have.
You can be sure that the major retail stores have people working for them whose job it is to figure out economical ways to fight insider crime, but we can tell from the news, such as computer breaches, that many of these places are a bit unconcerned about security when it is their customers being ripped off by identity theft.
