I'm going to change that roll into a Matrix Perception roll.
MM, the first thing you'll want to do before hacking anything is get a good look at what's going on. This is a Matrix Perception Test (which Pennies isn't particularly good at). So I am turning that roll into a series of Matrix Perception Tests. Intuition (2) + Computer (5) + Hot SIM (2) - Grid (2) - Noise from Distance (3) - Noise from Sprawl 2 = 2, so 5 separate tests. Happily, you don't glitch

As you are trying to get a look at the Cameras, you'll need to access the host they are on, so that's what you are looking for. The Host is not 'Running Silent', so you find it pretty easily. Now you want to get an idea of how beefy the host is. Each Net Hit on a Matrix Perception Test will give you a question to ask.
What is the Host Rating?
What is the Firewall (Data Processing/Attack/Sleaze) attribute of the Host?
What devices are slaved to the Host?
What grid is it on?
And any other questions you might think of. Of course, this is an opposed test and, sadly, it successfully opposed all of your rolls. The good thing is that this was just a look, so no alarms or anything are set off. Anything that uses your Sleaze or Attack attribute on your deck (Hacking actions, mostly) will set of alarms if you fail. This is why you want to get an idea of how strong the Host is, so you can better prepare yourself, since failing a Hack action could hose your run from the get go.
Also, to mitigate those minuses:
Hop Grids (A simple hack on the Fly action to hop the grid. It will start your GOD score, but you'll lose the -2 there)
GET CLOSER!
Start up your Signal Scrub program (-2 to the noise)
As it stands those negatives go against any test you attempt against the host, so you'd be -5 total to hack it, too.
