CCTV/IP Camera Storage Solutions

Problem:
  • IP cameras now are cheap, but there's no good solution for storage.
  • Cheap cameras have no local storage.
  • Cheap cameras can email, but now you have to wade through thousands of emails.
  • I couldn't find any cheap FTP services
  • Even on expensive cameras, storing on microSD cards is vulnerable - it lets anyone with access to the camera destroy or even copy recordings

Solution
There are sites that offer hosting services (e.g. search ip camera hosting). They even support webcams. However, they're ridiculously expensive. CameraFTP starts at $3.50 a month, for the worst image quality, only 1 camera, and only 7 days storage.

Why can't we use free cloud storage like Google Drive and Dropbox? Problem: they don't support email or FTP uploads, even for photos. Since none of the companies support this, it's obvious it's an intentional omission, probably to prevent abuse (like website image hosting).

Well, there are websites that provide email-to-cloud services for you. And https://www.emailitin.com/ is only about $3 a month for unlimited use... Since I've started, their files counter has doubled. It works great so far. Pictures from the camera are stored in my cloud service, for as long as I want, to browse like any other photos. I can even add as many cameras as I want, or allow others to upload too.

Xiaomi Mijia 1080P Smart IP Camera SXJ01ZM

Most official webpage I could find: https://www.mi.com/mj-camera-1080p/ don't be fooled, there are lots of Mi "fan" pages. Some are inaccurate. All try to sell you stuff.
A good review: http://www.jayceooi.com/mijia-1080p-ip-camera-review/

Ugh, Xiaomi, can you come up with unique names for your cameras? There must be like 5 cameras called "Mijia". How to distinguish this camera:
  • Obviously the best is SXJ01ZM, but not many places call it this.
  • Some places also refer to it as 130°, which is pretty unique, and distinguishes it from the 360° cameras that look the same.
  • There are a couple of cameras that look like this - black circle in white oval frame. The 360° ones, more expensive, have the black part protrude out the front when viewed from the side. I think this is the only camera where the black part is removable, a feature I like (see below)

This is what it looks like. As is usual for this blog, I'm going to focus on things other blogs don't cover. Here are the features covered by every other review and reblog that I'm not going to repeat past this:
  • 1080P full HD
  • 2.4 and 5 GHz dual-band wifi
  • Bluetooth (for setup and auto sleep)
  • Night vision with IR LEDs and IR filter. You can hear the filter moving in and out.
  • It's only 20 FPS?
  • WDR (same as High Dynamic Range)
  • microSD card slot
  • 2-way audio
To me, the most interesting feature is you can take out the black part and hide it better. The white part is just a frame.
Other interesting features:
  • Well the main selling point is the price, other brands' HD cameras are twice the price
  • It runs off microUSB (power only, no data) so you can power it from a USB battery
  • I'm not sure how common a moving infrared filter is on these cameras, but I always find it interesting
  • Using Bluetooth, it can detect your Mi band or phone (which brand?) when you're nearby and stop recording

Summary:

  • It does what it's meant to do very well. And coupled with the low price, this is a bargain - if it meets your requirements. Unfortunately I always seem to have unusual requirements, so it falls a little short for me.
  • By "very well", I mean image quality is good, it's relatively easy to setup and use, 130° is super wide (compared to my cheap Dlink camera; don't know if it's wide for other cameras), and I think its strongest point is it's easy to immediately see what times motion was detected.
  • My main concern, which I think applies to all users, is its heavy dependence on the Xiaomi servers. Its functionality is severely limited without them. This has 2 issues: 1. dependency - what if Xiaomi or your Internet access goes down etc. 2. security and privacy

Setup:
  • It talks during setup! Fortunately, it doesn't seem to make uncontrolled noises at other times.
  • You can set it up for wifi networks while you don't have access to that network. e.g. you can set it up at home for your office network.

Offline use:

There are basically 3 recording modes: continuous, motion detection and off. Motion detection lets you set areas and sensitivities. No sound activation. Sound recording can't be turned off.
You can also put the camera to sleep, during which the only thing you can do is turn it back on. i.e. you can't review files. So stopping recording (the top picture) is a better idea. Oh since the latest app update, the Chinese "stop recording" has been properly translated to English.

XiaoMi and SJCam, can you stop calling it "watermark"? It's a time and date stamp!

Storage
  • You NEED a microSD card. Without a card, you're limited to live viewing (and maybe recording from the app)
  • With a microSD card, you can also record to a NAS.
  • Surprisingly, no email or FTP like on even the cheapest Dlink cameras

Mercury MaxPlug 6 USB Smart Quick Desktop Charger 10Amps

  • 5 USB ports, up to 2.4 A each, total 8 A
  • 1 Qualcomm Quick Charge 2.0 port - 5V 2.1A / 9V 1.67A / 12 V 1.25A
I was wondering who the real manufacturer/OEM of this USB charger was, since Mercury is obviously a rebranding. Searching for Mercury MaxPlug didn't find anything. Well the inside says model ASSA60-050800-15W and searching for this returns very similar products, so I think this is the real model number. Hope this helps whoever's looking for the real manufacturer.

Always searching for a better charger. Innergie is my favourite, but they refuse to update themselves and come up with anything more than 2 ports. Anker is popular and I have 2, but they don't have Quick Charge.

Splitting Thinkware Video Files

If you have the rear camera installed in your Thinkware dashcam, the 2 video data are stored together in 1 .avi file, which is a pain to view and share. Some video players can only view 1 video stream. VLC opens additional Direct3D Output windows all over the place. Thinkware's software is useless for this. Score another black mark against Thinkware since other brands' software have easy ways to split/export videos.

I've found a solution!
https://dashcamtalk.com/forum/threads/how-to-best-save-2-channel-avi.8699/#post-109021
Using ffmpeg, the magic words are:
ffmpeg -i test.avi -map 0:0 -vcodec copy output1.avi

Sjcam M10 Action Cam

I grow increasingly frustrated with my Thinkware dashcam. At best, it takes 45 seconds to boot up. This in itself is ridiculously and unacceptably long. Sometimes it restarts and doesn't start recording for 2 minutes!

So, I got the M10 (actually M10 wifi), mainly because it had auto start stop (search for action cam auto start stop), meaning when power is applied, it turns on and starts recording, and when power is removed, it shuts down.
MAIN PROBLEM: if you leave the battery in the camera and the camera in the car, the battery will swell in a few months. This sounds too dangerous. Fortunately it "works" without the battery, except the camera doesn't get to shut down properly so the last video is corrupted. Some people don't have this problem https://dashcamtalk.com/forum/threads/sjcam-m10-as-a-dashcam.13427/page-4#post-267637
Observations:
  • The M10 starts up and starts recording within 10 seconds when power is applied. This just highlights how abysmal the Thinkware is.
  • Videos are divided into a minimum of 3 minute blocks. There's less than a second gap between videos (I couldn't measure the gap on my watch). Remember, the last video is corrupted, so drives less than 3 minutes may not be recorded.
  • Speaking of corrupted, I suspect the data is there (the file is), it's just missing the "packaging" (headers). So it should be fixable. This is also a problem on Dji drones and GoPros, and there are small programs to fix them. I didn't manage to fix the M10 videos though.
  • Mine doesn't seem to have any internal power at all, if I remove the battery when the camera is off, even for a few seconds, the clock is reset.

Problems:
Update: This is complicated. I'm doing more tests. It seems files are ok before the card is full.
There's a major problem since I'm using it without the battery. The clock resets, and since files are named from the date and time, all the files have the same name and the camera wasn't designed to handle this. I'm not sure if it flat out doesn't save if there's already a file with the same name, or overwrites it, but most of my files couldn't be played and I couldn't find any of when just starting the car, the sole aim of this camera. If you're looking for a dash cam, a dedicated one may be better. Not really this camera's fault, it wasn't designed to be used without the battery.
Possible solutions?
  • Set the clock / keep formatting the card - not practical.
  • Manually start/stop recording at a random time so the files don't collide.
  • Use the battery. Protect the camera from heat / avoid continuous charging to prevent battery swelling.

Update
It's not that bad. The filename format is:
yyyy_mmdd_hhmmss_xxx.MOV
where xxx is a kind of a running serial number. It's supposed to reset when the camera is switched off, but it takes longer than that (see how the first few files have serial numbers as high as 30. The date and time of 2016_0101_000005 indicates these files were the first created when the camera started, yet the serial number is already up to 30). Files are named with the time at the START of the recording. You can see most of the hhmmss in the files below are 000004 or 000005, showing that the clock starts 4-5 seconds before recording starts. Thanks to the serial number, there don't seem to be any conflicts.

The files without thumbnails are the corrupted ones because the camera wasn't shutdown properly.

So, the problems are:
  1. Last file before shutdown is corrupted - you can avoid this simply by stopping recording before turning off the engine. It only takes 2 button presses and no waiting.
  2. All the dates are the same so it's hard to tell which file is today's, yesterday's etc. 
  3. When the card is full, overwriting older files doesn't work so well. Because the camera can't tell which files are really older when they all start with 2016_0101. In particular, it rewrites the 0 and 3 minute files first. Other files seem ok:
This is troublesome for me because the 0 and 3 minute files are exactly the files I want, those that cover the startup of the Thinkware camera.

Summary:
It seems to work ok until the card gets full and has to overwrite files. So if I format the card before it gets full, it can cover my needs, except the last file is corrupted.

Lens Cover:
The camera is nice, but it's not very popular and the bubble-shaped lens protrudes, so it's difficult to find lens caps/covers to protect the lens. You can use the waterproof casing. I found this one that sort of works:
https://www.gearbest.com/action-cameras-sport-dv-accessories/pp_1510542.html
"Minismile UV Filter Lens and Lens Cover Kit for Xiaomi YI II / 4K Action Sport Camera  -  BLACK 250035301"
The clear one is like a UV filter - you can use the camera with it on. It's a bit big. You can wrap some tape on the lens or filter to tighten it up. I use PTFE thread seal tape (plumbing "teflon" tape), which doesn't have any glue. There's some vignetting in the right corners, only visible in videos, not pictures. I think you can get rid of it if you position it just right.
The opaque cover fits and doesn't drop, but it touches the lens.

Xiaomi PM2.5 Detector

https://xiaomi-mi.com/air-and-water-purifiers/xiaomi-mi-pm25-detector-white/

Remember my air purifier posts?

My search for quantifiable air quality led me to this PM2.5 meter. Random specs:
  • OLED screen (black and white, dot matrix)
  • 2 hour battery life
  • Has wifi, but not very useful
  • Has clock mode
  • There's a tiny fan in the back
Yea... what else do you want to know? This blog probably knows more than me about air purifiers http://www.myhealthbeijing.com/china-public-health/my-quest-for-the-ideal-air-purifier-is-over-xiaomi/
Again, air and water. Everybody needs these. All the time. Yet there is very little, you could say practically none, measurement and control over their purity, done by individuals. People only react to problems when they arise. No prevention and monitoring.
Singaporeans baffled by strong, mystery smell 26 Sep 2017
"A strong odour that smelt like burning chemicals or petrol, along with smoke that stung the eyes, fanned anxiety among many yesterday as it spread from north-eastern parts to the western areas of Singapore."
"The SCDF said at 9.55pm that its monitoring teams have not detected the presence of toxic industrial chemicals in the air.
In an update at 10.34pm, the NEA said it had received feed-back from the public about a gas smell in Sengkang and Punggol around 5pm.
"NEA officers were deployed to those areas immediately to investigate the smell feedback," it said, adding that air quality levels during the period were found to be well within safety limits."
Does anyone see the problem with this? We can only test for specific things, things we expect. Faced with an unknown chemical, we're helpless.

Anyway, sorry, this product won't help with this. It only measures particles. It doesn't detect organic compounds like alcohols. There are some detectors that detect formaldehyde and CO, but, again, these are very specific and won't warn you about other chemicals. Interestingly, the air quality sensors in air purifiers like the Panasonic one I have react to solvents like alcohol, as well as particles. If only there were a way to get a number out of them...

So here are some observations about the Xiaomi one:
  • Has wifi, which doesn't do much. Can connect to the Xiaomi server and let you see remotely, and occasionally log data. You can use it 100% standalone without wifi, then it's a simple display of PM2.5. Wifi can't be turned off though.
  • Seems to be meant for the China market for now. You have to set your locale to China in the Xiaomi app. At least you can switch the language to English.
  • DOES NOT LOG. Not their fault, I don't know why I expected it to. If you're connected to wifi, it seems to save readings every 30 minutes in the server. Doesn't seem to have memory of its own.
  • There's a clock mode, which isn't very useful. Time in 24hr format, date and day in Chinese. Can't be changed. Main problem is it reverts to clock display, which doesn't show PM2.5, you know, its primary purpose. No wait, main problem is IT DOESN'T SEEM TO EVEN MEASURE PM2.5 IN CLOCK MODE. By this I mean when I switch from time display to PM2.5, it acts like it's booting up and you need to wait to get a reading. At least clock mode can be turned off.
  • There's also a night mode, which doesn't do anything that I can see.
  • PM2.5 doesn't seem correlated to visible dust. I mean I still get low PM2.5 readings in dusty environments. I guess dust is bigger.
  • Shuts off in 30 minutes when running on battery.

So far, I think design is good, quality is ok, but it can be so much better with a firmware update. Choose clock faces? Display PM2.5 and time... together? Ok I'm assuming it doesn't even have a few kB of data for logging, which is poor design, but... log directly to the phone? Wifi hosting for portable use?

Reminiscing 2

Reminiscing, 18 November 2011

  1. Wow, this blog is 8 years old
  2. The wave of nostalgia continues, greatly boosted by SG50. Now there are all kinds of products inspired by history, not just the 90s. I'm perfectly ok with reminiscing, but not with pretending like you're part of a secret club that turned out ok despite the trauma of growing up without the Internet.

https://en.wikipedia.org/wiki/Ghost_Leg
I was thinking about this mini-game in a Sega Genesis game, where there are 5 vertical, straight, parallel, narrow islands and you pick 1. You walk up the island, and there are bridges randomly connecting adjacent islands. If you come to a bridge, you must cross it. It's a random chance way of picking a bonus prize, like drawing lots. Read the Wikipedia article, it's got a better description.

Anyway the Genesis game is very old and I thought it was pretty small and unknown, but I still found it. It's called Magical Hat no Buttobi Tabo! Daiboken. Aah, this brings back memories.

Fractions Of Petroleum

I see that a lot of petroleum products are just mixtures based solely on molecular weight, nothing else. It's weird, right, petroleum is a multi-billion dollar industry and I can't find such a complete list of petroleum products, by increasing molecular weight, that contains terms used in different countries, that I had to make my own:
  1. Liquefied petroleum gas 
  2. Naphtha  (5-12 carbon atoms)
  3. Petrol/gasoline (5-8 carbon atoms)
  4. White spirit/mineral spirits/mineral turpentine/petroleum spirits (7-12 carbon atoms)
  5. Kerosene/paraffin/lamp oil (6-16 carbon atoms)
  6. Diesel (8-21 carbon atoms)
  7. Mineral oil/paraffin oil/liquid paraffin
  8. Petroleum jelly/Vaseline
  9. Paraffin wax (20-40 carbon atoms)
  10. Fuel oil
  11. Asphalt/bitumen/tar 

https://chem.libretexts.org/?title=LibreTexts/Sonoma_State_University/SSU_Chem_335A/Material_for_Exam_2/Unit_3:_Organic_Compounds:_Alkanes_%26_Their_Stereochemistry/3.8_Gasoline:_A_Deeper_Look has a good general classification:
  • 1-4 carbon atoms - gases
  • 5-10 - naphthas 
  • 10-16 - kerosenes
  • 16-60 - gas oils
  • >60 - lubricants
  • >70 - fuel oil
  • >80 - asphalt

Types Of Memory

No, I'm not talking long term and short term, which seems to be the only differentiation.
It seems there are a few kinds of memory. At different times, some kinds are better than others. Here are some kinds I mean:

Self-Triggering / Reminders
Remember to do X when A happens. Siri, remind me to email Alex when I get home.

ToDo / Train Of Thought
Things I'm going to do next. Not so much a list as your next objective. What did I come into this room for? http://www.bbc.com/future/story/20160307-why-does-walking-through-doorways-make-us-forget
For me, most commonly it's when I'm browsing something, I'll think "shop for X next" or "visit website Y next", then a moment later I can't remember what I was going to do.
This is the kind of memory I seem to have problems with the most, or the first kind to have problems.
Might also be related to the nagging feeling that you're forgetting something. This could be due to you really forgetting, or actually not having forgotten anything ,just having problems clearing the reminder in your brain.

Lists
Speaking of lists, I wonder if they're another type of memory. Certainly memorising lists uses a different kind of memory.

Tip Of The Tongue / Vocab
Inability/difficulty to recall the word of choice.

Autopilot
Did I lock the door? Turn off the tap?
There are stretches of our experience that simply aren't recorded.

Credit Cards In Singapore

  • 8% off dining (Citibank)
  • 6% off dining (OCBC)
  • 8% off groceries (Citibank)
  • 3% off everything! (UOB)
  • 1.5% off EVERYTHING! (Amex)
There are a few (advertisement-driven) sites comparing Singaporean credit cards. And indeed, there are some nice-sounding offers. But none of them tell you this. $75. That's the magic number. $75 is the most you'll get back from every card every month. It doesn't matter what they offer, 3% cashback or 8% or even 100%. In all their terms and conditions, it's all limited to $75 a month.

"Oh what about Amex? They say they have unlimited cashback" Well they use a sneaky trick. Tell me, what's the usual credit limit? 2-3× your salary, right? What's your credit limit on Amex? Well it's conveniently so that if you use it all up, your rebate is $75. What a coincidence!

Alarm Clocks

I really want an alarm clock that tells you "alarm set for x hours from now" whenever you set an alarm.
  • I don't want sleep analysis of times, sounds or movements
  • I don't want to be woken during light sleep within a period of time
  • I don't want a reminder of when to sleep
  • I don't want night/yellow light modes
  • I don't want fancy sounds, weather or news reports 
  • I DONT WANT TO SOLVE PUZZLES TO TURN OFF THE ALARM

Unfortunately although Apple has run out of ideas and is poorly implementing whatever they can think of (
https://discussions.apple.com/thread/7668973?start=15&tstart=0) at the cost of good design (forcing the clock app to night mode). They haven't thought of this. 

And I had a look at 3rd-party alarm clocks, this feature also isn't very common. But it looks like even for apps that have it, they're a poor replacement for the iOS clock, because they can't override the silent switch, and maybe even Do Not Disturb. Also running in the background severely restricts their notifications. 
https://oleb.net/blog/2014/02/alarm-clock-apps-ios/ 
If I have to leave sounds on, what do I even need an alarm for? 

BlogTouch (Blogspot/Blogger app)

It's 2017, there's MORE social media available on mobile than on web browsers, but blogspot has been abandoned by google or something. I'm testing BlogTouch, a 3rd-party app that lets you post to blogspot blogs. It shouldn't be so hard!

Belts

Klik Belt
https://www.amazon.com/dp/B01B24TYO0
lol what? "Horrible design. Huge disappointment." https://www.amazon.com/gp/customer-reviews/R1IBQEIF7Q2S2R/
You have to remove the buckle to put on and take off the belt. What terrible design is this? It also loosens by itself. What? Seriously? This is a worse belt than a piece of string.

Carbon Tactics' Cinchy
Originally a Kickstarter project https://www.kickstarter.com/projects/520589318/cinchy-20-carbon-fiber-belt-system
Now regularly shows up on Massdrop https://www.massdrop.com/buy/carbon-tactics-cinchy-cti
Very simple design, basically just a solid monolithic buckle. Unfortunately it seems the strap is too stiff and uncomfortable: https://www.massdrop.com/buy/carbon-tactics-cinchy-cti/talk/588858

Grip6
https://www.amazon.com/dp/B018I1NP9U
Like the Cinchy, just a strap with a solid-state buckle. No one's mentioned this, but it also looks difficult to tighten. You know how all other belts have the excess belt on the outside so you can easily tug on it to tighten your belt? Yeah this belt has it on the inside, between you and the rest of the belt. It looks nice and seamless on the outside, but hope you have a strong pinch.

Update 24 Jun 17
New belt on Kickstarter by Carbon Tactics:
I'm backing this one since it seems to solve the problems of the Cinchy and Grip6. The buckle hooks onto a loop at the end of the belt, and you only need to move the buckle when adjusting the belt size. It saves your position.

Things In 2017, Part 1

Wow, another year. This year I'm going to split this into several posts. It's a mess trying to keep a single post for a whole year.

January
A spate of drivers driving against traffic on Singapore roads, beginning with a man driving a Mercedes in the wrong direction on the AYE, at 120 km/h, leading to 1 death on 20 Dec 2016.
SAF's Terrexes returned from Hong Kong

February
Kim Jong Nam, Kim Jong Un's exiled half brother, was murdered? assassinated? at Kuala Lumpur International Airport, Malaysia on 14 February 2017. Situation between Malaysia and North Korea deteriorates to the point that they both expel each other's ambassadors from their countries, and prevent each other's citizens from leaving.

March
South Korean president Park Geun-hye removed from office
Brazil found to be exporting rotten meat in scandal
Some countries ban electronic devices with big batteries on flights, due to terrorists possibly hiding bombs in them
Man drives car into people then attacks people with knives in London

April

US launches missiles at Syria
Singapore - City Harvest leaders who were found guilty have their sentences reduced on appeal 
Churches in Egypt bombed 
United Airlines forcibly evicts a seated, normal paying passenger from UA3411 for its crew because flight was overbooked. Outrage ensues (I was going to put his picture but I won't out of respect)
Tensions rise between North Korea and the US, after some missile launches and military drills
11-year-old Johor boy, Mohamad Thaqif Amin, beaten in school, gets infection, has legs amputated, dies

May
Singaporean Mr Jimi Cheong, on holiday with his family in Tokyo, has cardiac arrest while in Tokyo, needs $120,000 for medical fees and $120,000 for medical evacuation, which is raised by his family through crowdfunding. Unfortunately he died soon after arrival in Singapore.
"Ransomware" attacks, mostly in hospitals in England. This is actually pretty smart and profitable - they encrypt your computer, holding your data hostage, and charge you to decrypt it.
Bombing at Ariana Grande concert in Manchester, killing 23
Indian Actor Shrey Bhargava complains about Ah Boys To Men 4 audition after being asked to portray an Indian caricature. There is support on both sides - freedom of caricature, caricature isn't real, vs. racism, humour at the expense of others etc.
Clash between militants and security forces in Marawi, southern Philippines

June

Most of our online services are paid for by advertising, so I don't want to block all ads. However, there are unscrupulous and even malicious ads out there that have to be blocked. Previously, we saw how to block ads on computers. Here are more options:

Block ad domains on your router
Advantages: works on all the devices on your network
Disadvantages: your router must support it. Might be a limit to the number of sites you can block. Doesn't work when you're mobile.

Block domains on OpenDNS
Signing up for a free OpenDNS account lets you blacklist certain domains/sites/addresses. You can set your router to use OpenDNS, or set it on individual devices.
Disadvantages: only works at home / doesn't work when you're mobile. I think there's also a limit to the number of sites you can block.

I just discovered an iOS app that can block addresses, anywhere on the device (so in all browsers, games etc.) called AdBlock by FutureMind. It's pretty clever, it sets up a dummy VPN that doesn't work, and redirects requests for blocked sites to that VPN. Sort of like redirecting to 127.0.0.1 in the hosts file.
Advantage: only method to block sites when mobile that I've seen so far
Disadvantage: I think this prevents you from using other VPN.
