What the thread found

• Inexpensive 2.4GHz wireless video transmitters and receivers designed for security cameras can provide usable video transmission over short distances without licensing requirements in Australia and New Zealand
• Compact transmitters smaller than a 9-volt battery can transmit video reliably up to 20 meters indoors through walls in practice
• Budget wireless systems require direct line of sight to the receiver for best performance and may not maintain signal lock over time due to lacking PLL frequency stabilization
• Different 2.4GHz receivers operate on different subsets of available channels within the band, so a generic 2.4GHz receiver may not tune to a specific transmitter's frequencies even when both devices operate in the same overall frequency range
• The Jaycar brand offered compact 12-volt video transmitters and multi-channel receivers suitable for on-set video monitoring at low cost
• Power output differences between 1W, 5W and 10W transmitters affect range and signal quality, with higher wattage generally providing better performance
• Budget wireless video systems may produce RF interference with other wireless equipment on set, particularly radio frequency follow-focus systems
• No wireless transmission license was required for these 2.4GHz security camera systems in Australia

Depends on

• Discussion occurred in 2005 when product availability and specifications may differ from current offerings
• Users were testing budget consumer-grade equipment not designed for professional broadcast use
• eBay links referenced in the thread are no longer functional, making specific product verification impossible
• Shipping availability of Jaycar products to regions outside Australia and New Zealand was not confirmed
• One user reported signal drift occurring on unspecified equipment but noted it had not been a practical problem for them
• The specific Jaycar receiver model recommended by one participant could not be located online during the discussion
