On a chip pc it takes a loooong time to regenerate these totals, so we should only mark an hourly window to be regenerated when it actually has had frames deleted from it.

Need to document what the scope of the project is, such as Requirements, Installation, Architecture.

Virtualenv environment is tied to the system that you instantiated it on. There are paths that are unique in that generated environment that make it impossible to move from one machine to another, and security implications as well. It is advised not to include your virtualenv in your GitHub repo.

Now I just have to figure out how to do that!

By default, a browser will only run 6 concurrent requests to a single IP or CNAME. This is probably limiting the concurrency that is possible with powerful clients/servers and especially with object-stores like Amazon S3, OpenStack Swift (which I plan on supporting in CCTVweb). I do believe in those cases however, that those services explicitly distribute the URIs for resources over randomly generated CNAMES.

Ways to get around:

1. Make a config option that allows you to specify a pool of CNAMES to "load balance" requests for JPEG frames from the event viewer.
2. Tell the user to use DNS LB or somesuch? (bad practice though, DNS is not meant for LB)
3. Wildcard ephemeral/imaginary domains in DNS

Should go under a DELETE method, specify start and end frame in milliseconds since epoch. On the backend this just adds a field in each record "isDeleted: True".

Then, subsequent queries will not return those records.

Later implement a prune function that actually deletes the JPEGs to free space.

A neat overlay of some sort.

Instead of having to type the name of a camera.

index.html and static content serving from Flask. Gotta figure out if we can define routes both for API and for render_template in the same app.py file.

Sticking with Python2 as it's what I mostly need to write in for work, and it's supported by App Engine, just in case.

Create a config file for the Flask application:

serve_static_assets=True
domainname=domain.com
max-return-size= #max number of records to return in a single operation
debug=True
mongo_server=localhost
mongo_username=user
mongo_password=password
mongo_collection=images

Needs to be able to grab config.json in the root of the API server and apply those settings. Something with $scope in Angular is preventing this from happening even though it works totally fine in app.js.

using http://[ip of camera]/get.oid?TR3.4 style (IQeye API)

Place in a table called oids or camsettings.

How to do it on a schedule?

• Can also be used to graph things like image gain values, etc.

I've made this dependent on the folder structure that the images are saved to, and this is not good practice because

1. the user may have their own file structure and ideas already
2. it is fragile in general
3. the code looks nasty

Instead, we should use find, which should be on all platforms anyway.

Script to delete JPEGs from storage on a recurring basis. Either driven by crontab or external HTTP trigger. Need to clear the image_delete SQL table when completed.

This will provide asynchronous non-blocking I/O to allow the Angular service to do processing in the background without the DOM waiting on the controller.

Move to the previous or next event inside the player without having to return to the index page.

For easy deletion, etc.

Make sure to tell the client which resources can be cached and for how long. Since this isn't a single page application and .js must be loaded every time a page is opened, we can hopefully speed this up by taking advantage of browser caching.

result is like so:

either commit the entire line, or nothing.

This is where static content goes in django

As part of a pipeline, make it accept stdin, or path to a file.
