Sometimes after updating the Firmware of the Spark/PTZ the version number in the Admin page won't display the new firmware version and continue to display the old version which leads people to believe that the unit hadn't update. Please keep in mind that the unit did properly update, it's just caching the old firmware version in the browser and it should display the correct firmware version after you clear the cache. Here are some instructions on clearing the cache for various browsers.
Chrome: Clear Browsing Data
In Google Chrome, clearing the browser cache is done via the Clear browsing dataarea in Settings. From there, check Cached images and files (as well as anything else you want to remove) and then tap or click the CLEAR BROWSING DATA button.
Assuming you're using a keyboard, the quickest way to Clear browsing data is via the Ctrl+Shift+Del keyboard shortcut.
Without a keyboard, tap or click the Menu button (the icon with three stacked lines) followed by More tools and finally Clear browsing data....
See How to Clear the Cache in Chrome [ ] for more details.
Tip: Choose the beginning of time from the Clear the following items from option at the top of the Clear browsing data window to make sure you get everything.
In Chrome's mobile browser, go to Settings and then Privacy. From there, choose Clear Browsing Data. In this menu, check Cached Images and Files and press the Clear Browsing Data button once, and then again for confirmation.
Internet Explorer: Delete Browsing History
In Microsoft Internet Explorer, the browser that comes pre-installed on most Windows computers, clearing the cache is done from the Delete Browsing History area. From here, check Temporary Internet files and website files and then click or tap Delete.
Another option is via the Tools button (the gear icon), followed by Safety and then Delete browsing history....

Firefox: Clear All History
In Mozilla's Firefox browser, you clear the cache from the Clear Recent History area in the browser's Options. Once there, check Cache and then tap or click Clear Now.
The Ctrl+Shift+Del keyboard shortcut is probably the fastest way to open this tool. It's also available from Firefox's Menu button (the three-lined "hamburger" button) via Options, then Privacy & Security, and finally the clear your recent history link from the History area.

Safari: Empty Caches
In Apple's Safari browser, clearing the cache is done via the Develop menu. Just tap or click Develop and then Empty Caches.
With a keyboard, clearing the cache in Safari is super easy with the Option-Command-E shortcut.

Tip: If you don't see Develop on your Safari menu bar, enable it via Preferences, then Advanced, followed by selecting the Show Develop menu in menu bar option.
Clearing the browser cache from mobile Safari, like the one on your iPad or iPhone, is accomplished in a different app. From your device, open the Settings app and then find the Safari section.
In there, scroll toward the bottom and tap Clear History and Website Data. Tap Clear History and Data to confirm.
