DRS could be used only for Tests

Sri Lanka and Australia are likely to have the DRS only for the Test-leg of the upcoming tour because of a shortage of cameras required for the minimum technology standards. Only one of five necessary cameras are available as the other four are being used in the ongoing Test series between England and India.
"We are in touch with the ICC and the Australian company that is handling the equipment to try and make the technology available from the Twenty20 International, but the hitch is that they don't have sufficient cameras," said Upali Dharmadasa, Sri Lanka Cricket's interim chairman.
It was initially reported that SLC were not going to use the DRS because of financial constraints but Dharmadasa cleared up that confusion. "We were made to understand that the DRS became mandatory from October 1, 2011, but when I spoke to ICC CEO Haroon Lorgat, he told me that the DRS was mandatory at the end of the ICC meeting in Hong Kong on June 30. So we decided to go ahead with it.

"We told him that SLC had not budgeted for the use of DRS for the series, and if the ICC could help us in some way to cut down the costs, it would be helpful. Mr Lorgat promised to assist us in whatever way he could."
Dharmadasa said Sri Lanka were keen to have ball-tracking technology also included in the DRS, a technology that is not being used in the ongoing England-India Test series.
Australia begin their tour of Sri Lanka with a Twenty20 international in Pallekele on August 6. The Test series between England and India ends on August 22, when the Sri Lanka-Australia five-ODI series also concludes. The three-Test series starts in Galle on August 31.
