Any day can be an excellent opportunity for having a family get together and watch your favorite movie outside. With the correct budgeting, you can purchase home theatre projectors in stores available in Australia and give your family a great day.
Considering that it is going to be outdoors, you should factor in lighting and weather conditions. Data projectors work best in darkened environments. Therefore, you can set the movie time to be after the sundown and also in ideal weathers, e.g. avoid rainy days. You can use a projector with a brightness of 2000 lumens for evenings or 5500 lumens for daylight if your budget agrees.
Usually, you can improvise and use a white wall for viewing. However, to get the best images, you may consider having motorized projector screens. Since it is an outdoor event, this equipment will be installed and removed when you are done.
You also have the option of looking for portable audio equipment. This comes in handy when you do not wish to move your indoor sound equipment. Portable powered outdoor speakers can give you enough sound without bothering your neighbors especially if you pick the pro audio type.
Also to get the best view, do not put your projector way back from the screen. If you do so, your image will be too large and distorted. With the help of a universal remote, you can switch to your favorite movie collection at the comfort of your sit. Always remember to put the av cables and power cords of recording equipment out of the way to avoid tripping.
