Gone Skiin'

In the Forensics Files thread one of the cases involves a security camera which used movie film, and someone was surprised that such a thing existed. Here are some photos from a 1973 issue of the Sunday Times Magazine taken from 35mm bank security cameras. They're quite fascinating because they look so unlike normal security camera footage.



The cameras were triggered by the silent alarm. They were loaded with 100ft of 35mm movie film, and would shoot two or four frames per second until it ran out.



The Federal Reserve System required every bank to have some form of surveillance equipment. In the early 70s, film was the best option available.



Some banks also had 16mm backup cameras which ran all day, taking a picture a few times per minute.

Those look pretty amazing.

Since they were shot on film, did they need to be developed or was there a playback system on hand?

Also, I'm imagining the naked dude in the first one is a Terminator?

By "developed" do you mean "did every frame have to be printed"?

Because film itself has to be developed before it can be viewed with a light box and loupe/magnifier. And then prints can be made. But my guess is that prints of every shot wouldn't be necessary, unless there was a naked guy being ogled or guns were being waved in the frame.

This system produced still shots, not movies.

We haven't had that spirit here since 1969.


Why is there a naked guy just standing there at a bank robbery? Is he one of the robbers? Had the Symbionese Liberation Army gone enthusiastically clothing-optional? Or was he a bystander -- perhaps the bank had a locker room for people to change into their banking costumes, and he was forced out to the lobby at gunpoint?

Yes, the film-based security camera is a cool bit of obsolete technology, but I have so many questions. :psyduck:

It creates a distinguishing feature that draws attention away from other features. It's the same reason bank robbers would wear halloween masks.

Witnesses are distracted by the fact that this guy is bare rear end naked that they don't tend to pick up on things like height, weight, scars, hair length and color.

One theory on the St. Valentine's Day Massacre is that they dressed up as cops which was a good enough disguise.

Oh right, I glossed over the took a shot every x seconds part of it.

I thought it tossed out film to review like in that Roger Rabbit scene with the portable film splicer thing.

Also it said that the film system activated after the silent alarm was tripped so likely someone saw the naked crazy dude and thought a discrete call to the cops was in order.

Seriously, what's up with that? You could literally buy a bunch of burner smartphones and hook them up to wifi and use the cameras on them and it would look way better than a lot of security camera footage.

A hi-def surveillance system would probably be expensive as hell given that the footage would require petabytes of storage and whatnot.

Not with the photo every second, or even two a second. I'd take a high res still at 2FPS versus nearly any system today.

Not really? You only have to store a day or so worth of footage and then just overwrite it if nothing happened that day.

A go pro hero3 can record 60fps 1080p for 4 hours with a 68gb SD card.

They don't have people watching the feed 24/7. Something might come up weeks or months later that would make looking up archived footage later nessessary.

The Great Twist
The cameras we use are 8MP, 1080p and only record on motion. 16 cameras on a controller has a bit over a month of footage on 2TB of space. A bigger controller with a real RAID would be easy to store data longer, but we've never needed to go back more than a month.

Of course the security camera's main purpose is to find reasons to deny employees raises and give them write-ups. Catching shoplifters is just a bonus.

You know what was fun? Being the only person who worked there who knew the password to (and how to even use) the security camera system. I never used it for anything nefarious, but I did use it to great effect to catch a bunch of shoplifters, which was always fun.

When I started working there they were using a system with a completely dead hard drive for storage :laffo:

Ditto on being the only one. I used it for legit stuff once or twice, but mainly just archived videos of employees falling on wet floors and tripping on lobby furniture so I could show them to them over and over and over

I used ours for illegitimate deletions. Like when I was drunk and decided that the office was closer than home. Now we do have sleeping areas for when returning from big trips for fatigue management, but I really didn't want the projectile vomit and the next morning full of me running around cleaning everything up to be seen.

Until about ten years ago most places that had a security camera had it recorded on a single VCR tape.
