On Friday night Motherwell host a Hibernian team who have been denied wins over Dundee United and Hearts in recent weeks by poor decisions.
Ryan McGivern was wrongly adjudged to have committed a foul inside rather than outside the box to conceded a late penalty at Tannadice while the officials last weekend failed to spot that a Leigh Griffiths free-kick had bounced over the line.
But Hibs benefited from two similar incidents on their last Friday night visit to Fir Park, a 4-0 win in October. Hibs goalkeeper Ben Williams scooped Stevie Hammell's effort out from behind his line and the Motherwell left-back later conceded a penalty for a challenge outside the box.
McCall said: "If we can't afford goal-line technology, we can't afford it. But we knew Stevie Hammell's goal 10 seconds later was a goal. Everyone knew Leigh Griffiths' goal was a goal 10 seconds later because the TV is there.
"I will concentrate on the football but certainly there is a debate to be had whether we can use the TV behind us. But if it's just when it's live on the telly that we get that, then it's uneven. It's all about making the right decisions but if it can't be the same for all clubs then that's a problem."
McCall, who has Shaun Hutchinson back from suspension and is likely to have Chris Humphrey fit following a knock, is of the belief that decisions tend to even themselves out.
"Every manager throughout the country could look back at decisions that have cost them points but likewise there are decisions that win you points," he said. "We could easily have got a penalty against Aberdeen, Hibs shouldn't have given away a penalty at Dundee United.
"Obviously when a goal like Leigh Griffiths' was so obviously over the line that brings attention to it but all managers are able to point to individual things in a season and say it has cost us points. Hibs are no different to us, we are no different to Aberdeen, who are no different to St Mirren.
"Referees give decisions in good faith, there are no hidden agendas and I would say probably over 90 per cent of decisions they get wrong, you can understand why because things happen so quick. If the linesman or referee is not 100 per cent sure, they cannot give it."
