So it's possible, yes, even with a single color laser of sufficient power. But is it practical?
First, this guy is using a 5W beam up close and not frying the sensor at all. 5W is a powerful burning diode, realistically diodes only get up to 7W before you're breaking into impractically huge laser setups. Even at 10W, you can probably figure this isn't going to burn the sensor out at the distances you'll need to use it. This means no matter the power, you have to keep your laser set up directly onto the camera at all times when you don't want it to see you.
If you watch videos of people using lasers at long distances, you'll see that it's finicky to get the laser to hit exactly onto one spot permanently and typically takes a long time of fine adjustments. You won't get the camera on the first try in all probability and even if you did, it'll probably hit elsewhere immediately afterward from shake.
This means two things - even if the laser could eventually fry the sensor, the set up process would still be on camera. Secondly... the set up process is going to be on camera. Lasers sufficient for this are bright and often leave a visible beam leading straight to the source. So, whoever reviews the footage is going to see where you were at and this is just one more lead during investigation.
Eventually, one could set up a stand that permanently blinds the camera (at least as long as you need it blinded). Yes, this could work during an operation.
However, there's a huge light exposure risk here. Again, lasers this powerful are extremely bright! At night, a 7W laser is like holding an infinite rod of light. Super obvious. There's no way you're going to use the laser discretely unless you're in a totally dark, closed area. In which case, blinding the camera probably isn't necessary since sufficient concealment will hide your identity and if the feed is being monitored in real time by a person then they're going to notice the laser blinding the camera anyway. Even if they're doing something else, a monitor going bright white suddenly tends to catch the peripheral vision.
As far as I'm concerned, this solves the question definitively and simply: Don't bother.
