Friend's sister was robbed at home yesterday. She had advertised a watch for sale (Rolex lady Datejust) and a chap came to her house to look at it.

As she was letting him out of the front door, he grabbed the boxed watch from her hand and ran off. Her and her dog gave chase, but he got away.

After calling the police, she checked her wireless CCTV camera. The footage froze as he approached her house, and resumed as he was running off - he obviously had some sort of jammer.

I've not heard of such a thing happening before, and it makes wireless cameras pretty useless if they can be easily disabled.
I don't know what type of camera it was, apart from the fact that it uses an internal SD card

Blocking WiFi (wireless cam) = easy enough. Blocking it recording to its own sd card....that would require a focussed attack with tech I have not heard about ,that would surely fry the camera.

She didn't accidentally erase the recorded data when trying to access it?

Or.... Much more likely, the SD card is corrupt and as soon as there is significant data to record (movement) it can't cope and it corrupts. Much like viewing a streamed cam with no movement works fine on a poor link, but add some action and it all breaks up.

With loop sd recording you are advised to format the card every so often.

Quick google would suggest thay you can buy devices that will jam wireless CCTV.....but for ones that seem to actually work are not cheap. So your guy would have to be at this fairly often to make it worth the cost.

Might be worth putting details up on watch forums as your unlikely to be his 1st victim

Her wireless CCTV wasn't jammed. It recorded (well, didn't) to SD. Nothing to do with wireless jamming.

"Quick Google" me a device that can interfere with local (internal) SD card writing .

My friend is staying with her sister, and was in the house at the time. She told me that "the footage was perfect before he arrived, and again after he left. It didn't record the whole time he was there".


Doesn't sound like an SD card issue, as it would have recorded OK while he was inside the house.

Either it's wireless or has an internal SD card? If the SD card is in the base where the camera connects to then it can be blocked.

Where does he say it records to internal sd card. He says he doesn't know what type, only it HAS an internal sd card.

I have a couple of cameras that also have an sd card, but they are wireless and dont use the internal sd card, and record movement to a server on the network.

Only things I can think of are:

1 - The Camera is using it's default login and the thief or an accomplish logged in and deactivated or deleted the recording.

2 - The camera is configured wrongly or malfunctioning so that it STOPS recording when it detects motion (instead of the other way around).

3 - When in the house the thief managed to get wireless router login details and from there him or an accomplish managed to access the camera.

4 - Could the power have been cut externally to the house by an accomplish to prevent CCTV recording? This to me is the most likely case.

5 - As someone else said maybe the user accidentally deleted the footage or the SD card has a fault.

It may well be this is a regular robbery method for this person and they have a well laid out plan to handle CCTV.

If its a wireless CCTV cam going back to an NVR, could have been a deauth attack on the camera.

Easy to do, would knock it offline to the DVR any specified period.

If this isn't the case, ignore my post smile

That was my first thought but re-reading the OP the camera has an internal SD card which has stopped recording too so kicking the camera off the WiFi wouldn't stop it recording, would it?

The deauth attack Carrot is talking about is a "deauthentication attack", where you can (worryingly easily) kick a device off someone else's network, I would link to a page explaining it but don't want people getting into trouble at work!

I'm not trying to be tricky here. The op said, ", apart from the fact that it uses an internal SD card"

I think most people would read that as the camera records to its internal sd card. No? Otherwise why mention it?

I tap out here. SD card is a red herring. Not enough detail.

I'd love to know the details op. If you can find out where the recording was made specifically.

I'm finding it very hard to imagine a petty thief would go to such lengths . If he was a serious thief he'd just show up in a baraclava and rob her. Instead it sounds like he took the path of least resistance - snatch and run.

P.s. sorry to hear of all this. Must have been horrible.

Not nice to hear.

I suspect that she needs to take the sd card out and read it using a reader. My cameras record to cloud using wifi but also have an internal card, if I watch back on the app it only plays back the cloud recording. You may find she has got the footage on sd.

She has taken the SD card out, but not sure what she used to try and view it. Possibly her iMac.

She has a crime reference from the police, but not sure if they will actually follow it up with a home visit for evidence.

Quite shocking to be robbed in your own home in daylight like that. I guess that's what insurance is for - as long as they actually pay out. Might prove to be a bit tricky, as he got away with the box and paperwork too.

I have a camera that works exactly like this. It is on the wifi network however it records to internal SD. If it disconnected from internet it still records and once reconnected uploads all footage to dropbox, other online storage and is then visible in the IOS app. To interfere with the SD recording you'd have to pull the camera off the wall and it is mounted pretty high.

Yes, I think exactly the same. Seems James Bond might have nicked her watch.

Does she maybe have an Arlo system? Wireless cameras but also backs up to an sd card which is contained in the arlo hub?

If they jammed the WiFi it would mean the hub wouldn’t receive the signal and therefore wouldn’t backup to cloud or onboard sd card.

OP, if your sister still has details of the watch I would suggest she registers it as stolen on https://www.thewatchregister.com. It will make it harder for the theif to shift via regular dealers, most people in the know will check this if buying via eBay etc.

It's my friend's sister who had the watch stolen. Since the thief took the box and papers, along with the watch, I doubt that she has a record of the serial number. She might have given the serial number to her insurer when she added it to her contents policy.

I've asked what make the camera is, and the only thing she could tell me was "it's white". I guess finding out how the thief beat the camera is fairly low on their list of worries right now.

Indeed, and understandable, but you asked..... the title of this thread. :-)

I know nothing about technology but would suggest this is a very bad idea - they’re ruthless bd tts and the consequences aren’t worth it over a watch, no matter how annoying.
