Okay, given Snow's impulsive and eager to please attitude, I am going to take advantage of the dice she has already given me so kindly and tell you all what she
actually just did.

(Don't get wound up about it Mercy, I am just trying to get things back on track without major rewrite...and having a little fun with it)
Upon examination of the device in Clem's image link, she makes a memory check to see if she recognizes the device, -1 to the check because she is opening doors for the infiltrators at the same time. (1,1,6,1,2,3, one success, but it is a glitch too) She has seen it before, but she has mistaken it because of Sammy's reference. Following that incorrect information, she begins to try and find the hidden node that the device would be linked to (if it's active, which is likely given that some of the sensor wires are unspooled and in a room).
Unfortunately, Snow's abilities as a Power User and not a full fledged Hacker are not really up to the task of detecting a hidden node by herself. (Previously doing this she would be working with a team, either Fionn or the spy folk she learned this kinda stuff from originally) Having no Electronic Warfare skill, (something I bet she will want to pick up after this) her chance of finding a hidden node on her own are almost non-existent. (
Electronic Warfare + Scan (15+, 1 Combat Turn) Extended Test ) That said, her successes on the initial check (3 6s and a 1) should have started to give her an inkling of the node considering it is running an active periphery.
It doesn't, this make her stop her search and take a closer look at the image of the device. Then she realizes why she can't find it. It is not an uplink device (satellite or otherwise) it is a laser repeater, it is tight-beaming the data from the recorder to a receiving device that the laser is pointed at. She wouldn't be able to hack it because if it is not wirelessly controlled, which they usually aren't, it is not on the Matrix to hack.
Sammy and Clem, once they get this information, can do Perception checks to see if the can spot a receiver, which will be in line-of-sight, but not necessarily easy to find..
