I would keep the glass in and put stick on privacy film over it. You will get a neat result, you can get a huge range of patterns and colours (start your search on eBay for examples) and you won't lose your wind protection in Winter. Handy when having a BBQ in Summer too.

Bunnings sell some very attractive & durable screens that you can install with a strong metal channel frame - quite straightforward to do yourself, and will attach to Colourbond with pop rivets & by extending the frame all the way to the ground to be safe... if you like them, ask a builder for advise just in case they blow into the neighbours shed & smash their windows! Orientating them horizontal rather than vertical, and running across the top of the fence perhaps. There's heaps of designs - here's one https://www.bunnings.com.au/matrix-1800-x-900-x-7mm-charcoal-orbit-decor-screen-panel_p3041106

It’s a great idea, that way you can alternate whenever needed without too much fuss, your balcony looks quite spacious so you can have some beautiful pots out there with the added bonus of looking lush from the inside, love these wall circles too.

I've had cameras ( and recorders ) for at least 15 years , with at least a couple of small 19" Tvs on all the time , and also picture in picture when the TVs are on . Not a direct answer , but I assume that is what most people do these days ? More discrete , better picture , with record function . As far as I can work out , a camera on its own is under $50 , a 19" flat screen TV probably $20 second hand ( lets face it , no-one wants them these days , and the older Analogue ones still work as a monitor ) . I'm in NZ , I googled and this one came up as being stainless and is $25 ( well $23.95 ) -- it is a smaller importer . Bunnings etc does seem to have brass only .
