why aren't surveillance high tech?

Been watching news lately and saw "suspects" played on surveillance that was so grainy that it's hard to make out what the person is. Isn't technology advance enough to be able to zoom in to it so it becomes crystal clear? I bet there's apps for such thing? I don't get why news media can't figure this out themselves so the viewers get a crystal clear view of the "suspects".

It's grainy because the cameras used to catch the scene are cheap low resolution shit

Yeah typical 7 eleven cam. Isn't there a software program that could remove the grain and zoom in on the surveillance? Not sure why crime caught on surveillance aren't high teched by parties that put out the surveillance in public.

No, there isn't not entirely. It's not like on tv series. If the pixel quality isn't high, there's no amount of zooming in that'll clear it up..in fact it'll blur it more

Actually Kif isn't totally correct, sometimes it's possible to derive previously invisible details by analyzing and combining the information in multiple frames of video (called "image stacking"). This can be used eg. to recognize the license plate in low-resolution security footage. I suspect news outlets don't do this because they would be introducing new data based on an algorithm, not reporting straight facts. For example, what if their software reconstituted the license plate number wrong and they put it on the air? I guess it's also possible that smaller local stations simply lack the budget or technological expertise to perform this type of enhancement. It's also not well-suited for all types of video, especially the fast action and jerky, low frame rates we often associate with surveillance footage. However, if video of adequate quality exists, I can only assume law enforcement makes full use of this technique in significant investigations to help generate leads.

I need to get my hands on these technologies so I can do my own investigations. Surveillance is a powerful thing.

Cost and durability. Mainly cost.
Most companies try to cut every single corner they can, including getting the cheapest security cameras that money can buy.
But the other problem is that the really really good consumer cameras are fragile and won't work in a business setting (where you need them to be really sturdy, survive outdoors, have a metal frame, etc.). If you wanted a really good camera that was also really durable, you're talking about a lot of money.

A big issue with security cameras is the storage of the video. High resolution video is generally pretty large, and while each company has their own policies on how long they want to retain surveillance video for, they tend to all want it long enough that systems would need some massive storage to store months of recording in high resolution. Most security setups have auto deletion/rollover so it records for say a week then starts overwriting the beginning of the recording over and over, but the longer you want it to be available, the more storage needed.
Like most things, its all about the cost vs performance. There most definitely are lots of high resolution security systems out there, but your average joe corner market may not want to dump tons of money into it if the lower resolution models work fine for their average risk/loss.
Take into account whats at risk. In a corner store I imagine a lot of their loss is petty theft from shoplifters. They probably have insurance to assist with stuff like that and the insurance company will pay their claim regardless of if the thief gets caught or not as long as there is proof of some sort. If every month only costs them say 50$ in lifted candy bars and mickeys 40's, why drop thousands upon thousands for a high resolution camera with good retention.
I work for a major bank at our datacenter location. The security cameras here are mostly high resolution, and federal law requires we retain records and data for most things for a minimum of 3 years. High resolution video and 3 year retention = massive storage array just for the security cameras, and on top of that, there are hundreds of cameras on our campus. The building security system on our campus is in the many hundreds of thousands of dollars in total cost. This does of course also include the badge readers and hand scanners, etc etc etc.. far more then just the camera system.

3 years of HD security video storage? That's like...2.6 petabytes of data per camera! I'm guessing even the "high resolution" security you mention is barely a quarter of that quality.

You can get very good high resolution security cameras dirt cheap on ebay for personal or business use. Thing is the cameras are more often just a scare tactic to prevent crime and to lower the insurance premium than they are actually used for evidence.
The installation and setup with the security company is the bottleneck. Many security companies don't have newer systems because they are networked with really old tech, and telling thousands of customers that "oh BTW we will be unable to archive your surveillance footage for the next two weeks while we upgrade our system." isn't really an option.
The smartest option is to have an encrypted HD video system using those tiny wireless cameras in combination with large obvious dummy cameras and a looping DV recorder that loops say every 72 hours both onsite and to a remote location.
I set up a system like this up at a Hindu temple after the horrible Sikh massacre a few years ago, and rigged it so that you could actually watch the video and audio feed live online during their religious programs so people could be there if they couldn't physically make it.
Sadly they had truly ugly issues with management and failed to maintain the system properly. Basically they added newer computers and a network router without my knowledge, and screwed it up royally. When i told them it would take time and money to fix their mistakes, they said they could not afford it.
I charge about 30 bucks an hour for this sort of work. Would have taken about 8 to 20 hours to do it, so worst case about 600 bucks. Hell they could have passed the plate on a holiday and easily got that. Recently they just took out a huge (READ: several hundred thousand dollars) loan to expand the temple and cover their gods and goddesses in REAL gold... Yet common sense security is too much, WTH?
In a nutshell, the best security is what at first glance looks like convenience and friendly customer service.

How those people able to zoom in on Martian photographs for a closer look?
What could give me an up close look at a grainy video? Could I use a binocular to view the grainy video? I should try? I'd assume binoculars could zoom my view on to the subject?

They zoom in similar to using any other optical lens system, by changing the focal length ratios in the telescope used. The graininess is because the image sensors used are older style ones that by necessity had bigger pixel size to enhance the sensitivity and radiation hardness at the expense of image quality. Making electronic stuff space-worthy is difficult because the radiation from the sun is blasting constantly like a nuclear accelerator.

Lowes and Walmart have like HD security cameras where you can zoom in on the details of a license if a customer had it in their hand.
Ive seen it personally. Dont know why LE wouldnt just do the same lol
Bums. They just rely on intimidating people into becoming informants to do their job.
