How about installing a Face Recognition Camera at the entrance gate... if a person is on the Blacklist (aka multiple times shoplifters and/or troublemakers), then it simply won't open! Security Guard stands there to enforce it.
That could work, but only for a smaller store. Stores which have hundreds of customers coming in and out every hour all day could not take this approach. Too slow & intrusive, witch such volume.
The security measures would have to be around the items, and this is what they do: display cases for high value items (or mandatory-by-law measures for pharma items like ephedrine, etc.).
However, he more you do that, the slower and less convenient for the customers and you also need more staff to handle opening & closing the locked cases.
London Drugs in North Van or Richmond could get away with doing it (but would they even need to?). London Drugs at Granville & Georgia might get away with it, but also might choose to have two guards on the door at all times, and 4 roaming around inside the store (costly). As for the London Drugs at the old Woodwards building? Forget it. The push-back from the community would be massive, and there's no assurance that it would even stop people who are so far gone they can be arrested 100 times and not care; that location is the #1 candidate for closure, choosing to eliminate service entirely rather than take the risk of providing it.
We have more than one jewellery store in Victoria that has to buzz you in. Don’t know about the double doors.
Most larger stores will not try to intercept do to the risk to staff. They pass on the losses to us honest consumers.
The folks at the government liquor stores tell me the same.
Lots of business have a window to order from. Especially late night gas stations.
Yup. Jewelry stores absolutely need to have this in place. I would: face recognition cams, airlock-style doors with bulletproof glass everywhere, and more.
Of course, that works for a place selling VIP items like jewelry. Banks too - for all the talk of robbing banks, it is rare now. Thieves face extreme security and rarely get any amount worth the risk.
Even currency & bullion exchanges take precautions like that, but notice this:
They also warn customers not to flash their cache or whatever and be aware of others when they leave. Why? Because the thugs stop targeting the store and start targeting the customers leaving it.
Canada is also grossly behind when it comes to surveillance technology. Its not as advanced as the UK or other places. In Japan they had a ninja thief who was breaking into places. The police weren't able to stop the break-ins. A camera caught the perp's face, a 74 year old man. His motive was that he didn't want to work. They used facial recognition software on surveillance footage when his masks slipped for a little bit when he was out prowling. Without that tech, they would not be able to identify him as they thought the ninja cat burglar was a young man. The Ninja of Heisei is a legend in my eyes. It really shows how behind our technology is. I bet airports and large entities have access to that, but I doubt most police stations will want that tech for petty break ins and small time thefts.
Having worked security let me let you in on a non-secret: whether cameras are actually monitored by a person watching is another matter. Most stores do not, as this would require a security person in a control room (as opposed to just cameras passively gathering evidence of incidents). Airports (YVR sized) definitely do have someone watching cameras all the time.
However, since the airport was mentioned, let me offer some wisdom.
Security / safety and convenience / openness are oppositional concepts. You can have near-perfect high security, but the trade-off is always convenience of use & that feeling of a relaxed atmosphere. In some countries, security is the only consideration.
In the 1990s, there was a really big push going on (in North America) to make airports as easy-going as possible, and make air travel as routine as boarding a city bus. Sure, they knew about terrorism and such, but it was seen as a problem only in problem parts of the world. International flights were still subject to security restrictions, but they thought that domestic flights required little or even none. Well, 9/11 was a gigantic slap across the face for the whole industry (which silenced all those who had said the people opposing relaxed airport security were "paranoid").
The airline & tourism industry learned a lot from that hard lesson, but you can still see today how the airlines, the tourism industry, and the passengers push back against the cost of security in time & money.
All these news stories about how the federal government failed to anticipate long lineups, blah blah blah, are really "sponsored content" where the industry is still pushing to have regulations relaxed, or just modified so that
certain passengers get VIP treatment and sail through security while the rest have to ensure early arrivals & long lineups.
In Canada this manifests itself as having NEXUS and other (basically bullshit) programs where some people going to the US (it is always for US travel, nowhere else) save lineup time by some trading off to go through as "assured" persons. Basically, an intrusive security / background check that hands over an enormous amount of data to the intelligence services. (PS: In Europe, they are in the process of adopting biometric data gathering for ALL arriving travellers, so that is the next stage.)
And what drives all this? Safety? Nope. MONEY. A calculation of how to pluck the most feathers from the goose while generating the least amount of hissing.
Airports are the extreme example, but you can apply that to security for any public-facing industry.
How can they be secure enough to not lose money to crime, without being so overly inconvenient and intrusive that they drive customers away and lose more money the other way?
