WiFi jammers against security cameras is such a 'duh' once you hear it. Wifi security cameras are so easy to beat with this. And unless you alarm on any downtime it leaves you fully vulnerable.
- walterbell 3y agoSecurity cameras should be wired PoE with local NVR + decoy NVR. Wi-Fi conveniently enables x-ray vision (IEEE 802.11bf) through walls of home, making it easier for attackers to identify where valuables are stored, observe password keystrokes, etc. Any room with a safe should have EMF shielding. https://www.cnn.com/2024/04/05/us/burglary-tourists-visa-waivers-target-luxury-homes/index.html https://www.cnn.com/2024/04/05/us/burglary-tourists-visa-wai... > Prosecutors say the break-in is part of a larger issue in which so-called “burglary tourists” enter the United States .. they join sophisticated burglary rings that prey on luxury homes.. “They take advantage of the fact that most people don’t have window sensors or motion detectors on their second floors. They have WiFi jammers to stop the alarm company from being notified.. the stolen goods are often sold quickly and the money is sent back to the suspect’s home country. Most often, that’s Chile.

- GordonS 3y agoSorry, could you expand on NVR please?
- Daneel_ 3y agoNetwork Video Recorder - basically, the place where the video footage is stored. It's essentially a NAS, aka a big box of hard drives.
- walterbell 3y agoe.g. Frigate OSS with local AI using Google Coral TPU, https://frigate.video/ https://frigate.video/
- dewey 3y agoYou record the data locally and not only stream it directly to the cloud.
- defrost 3y ago+ decoy NVR. Is always smart - use unique bright yellow (say) CAT cable to route from cameras to local storage .. and on the last leg route the real camera data to a hidden NVR behind a good false panel and "continue on" with fake yellow CAT to a decoy NVR in plain view. It's a good feeling when robbers have visually followed the bright cables to the decoy storage and trashed the drives that don't have the idiots faces and other data stored in HiRes.
- spacecadet 3y agoAn old friend of mine installed many security systems, he was all about the deception too. He had these fake looking cameras, like you see for $10 with the fake clipped cable, except he hid real cameras in them. Worked on several occasions where we assume people scoped out the location and decided they were fakes.
- addandsubtract 3y agoSecurity by obscurity surveillance
- spacecadet 3y agoHaha not the same. This is a honeypot.
- jazzyjackson 3y agosecurity made to look like obscurity security by bamboozlement
- brk 3y agoThat is a scenario that only happens in the movies. Even is really low quality installs, there isn't much exposed cable, and it's going to go into a wall/floor/ceiling fairly quickly. Robbers are not following network cables around like some kind of map line.

- throwiforgtnlzy 3y agoHeck, even the cameras I bought my mom were PoE with in-situ SD cards for self-contained recording and NVR, with a cloud option. An armored car company holding zillions of dollars can't bother to secure itself with even 2009-level residential technology or wall/ceiling penetration sensors is an absolute case study in security theater.
- sofixa 3y ago> Security cameras should be wired PoE with local NVR + decoy NVR. Shouldn't the NVR have real time offsite backups and/or a redundant NVR instead of a decoy?
- brk 3y agoNeither of those are common, or practical. First, decoy recorders are extremely rare, and never really recommended. Most higher-end systems are using software on a PC for the video recording, not a little NVR appliance anyway. In that case your recorder can be any random PC, potentially even hidden in plain sight. Real time offsite backups is usually not practical for reasons of upstream bandwidth limitations. A common camera can easily produce a bitstream of 2+Mbps. Get a dozen of those going, and you're bumping up against the upstream bandwidth limit of cable internet providers in the US. If you have the bandwidth for realtime offsite backups, then you can skip the on-site NVR/recorder and go with a full cloud solution like Eagle Eye (this will have a small onsite PC that acts as a buffer so that if you have a short outage of a few hours, or congestion, you don't lose video).
- Teever 3y agoMaybe these kinds of things are more commona and practical in the kinds of facilities that the article is talking about? Either way, in the city I live in most residences have 1gb up/down fiber connections. a real time offsite back up is trivial for anyone who wants to do that here.
- brk 3y agoThey're even less common in those kinds of places (I've been involved in thousands of commercial video surveillance projects). Internet connections have certainly become more robust in recent years, and cloud video storage is becoming more common, but I don't think it even makes up 1% of the market at this point. Offsite backups, remote storage, etc. are still the exception, not the rule. Overall, the video surveillance market has many price sensitive customers. Redundancy means increased costs, it is not an easy sell, particularly when attacks on the video surveillance system/components are exceptionally rare in most cases.
- eschneider 3y agoI spent over a decade working on security cameras and various NVR related applications. Hard wired cameras are more secure, BUT, if someone can get access to your network cable, it's not hard to inject packets and DOS out most UDP-based cameras. Most large sites put their cameras on segregated networks, so it might not even be obvious to folks for a while.
- amluto 3y agoI consider this to be an embarrassing property of modern networking. A network switch that tracks and enforces the mapping between addresses and ports, blocks spoofed packets, ensures fair allocation of DHCP leases, and enforces fair allocation of bandwidth out to be available out of the box from any credible vendor. None of this is conceptually difficult, and all the building blocks are available in somewhat standardized form. But for some reason, port security is an exotic enterprise-y set of features rather than something one can deploy out of the box. Or an NVR deployment could use 802.1BR to isolate all the cameras. I’m a firm believer in endpoint security — endpoints should not need to trust the network for authentication or authorization when communicating with each other. But the network really ought to be able to do its job despite attacks by rogue endpoints or someone compromising a single piece of network infrastructure, and the network’s job is to maintain reliable connectivity.
- eschneider 3y ago802.1BR would certainly help in that situation, but it adds management overhead. A large deployment of IP cameras brings with it a fair amount of IT overhead and the capabilities of most corporate IT departments (let alone the 'security department') can be challenged by even basic setups. I've spent a lot of time handling support for big camera deploys and I was surprised by the number of customers who would bring their systems down by misconfiguring their own networks.
- MisterTea 3y ago> I’m a firm believer in endpoint security — endpoints should not need to trust the network It's called Ethernet for a reason. You fling packets into the ether and hope they come out the other end. What happens in the ether is anyone's guess.

- walterbell 3y agoTrue, those are in white vans. https://www.rapiscan-ase.com/products/mobile/zbv-cargo-and-vehicle-screening https://www.rapiscan-ase.com/products/mobile/zbv-cargo-and-v...
- helsinkiandrew 3y ago> Security cameras should be wired PoE with local NVR + decoy NVR. Given that wires can also be cut, is that worth it given the extra cost to install? A better solution might be for alarm to be triggered if traffic from cameras is lost (although that would create a lot of false triggers)
- egberts1 3y agoWire cut is a definite hard alert. More reliable indictor than a jammed WiFi, way less false positive too.
- kotaKat 3y ago> Given that wires can also be cut, is that worth it given the extra cost to install? Proper camera deployment includes redundancy in camera viewpoints. If you're cutting a camera's cable, I'm seeing you cut it from at least one other camera on property.
- MisterTea 3y ago> Given that wires can also be cut, is that worth it given the extra cost to install? First off if the wires can be reached the installation is a failure. My cameras are up high with all wiring well out of reach or in metal conduit. Getting near the wiring also means theives get closer to cameras setting of motion sensing algos wasting time and risk making a racket trying to climb up to disable them.
- lttlrck 3y agoPerhaps it would be better if APs could detect jamming or deauth attacks.
- EricE 3y agoDetecting jamming still doesn't restore your cameras functionality. It's still jammed. Wifi is useful for many things - just not anything security related.

- MisterTea 3y ago> NVR + decoy NVR. A friend did this - he hid the DVR in a space under his steps then took a cheap dead DVR, gutted it and shoved an RPi in to run Firefox and the DVR web UI. Even set it up in with a monitor and mouse on top. He left the old HDD in there for weight too. One thing to think about though, he had a NAS box in his office next to the router on a table and I said, what if they take that thinking its the DVR? That is now under the steps too. > Any room with a safe should have EMF shielding. You just made the target that much more visible.
- spxneo 3y agoSingapore is simply the best security camera you can buy for you and your descendants. They will be bored (so will you) but will have energy because its not spent on fear. Safe houses, guns, these things are foreign concepts to many but especially to people living in a benevolent dictatorship countries. Tito, René, Lee Kwan Yew, Park Chung Hee. Only two countries remain true to its art form.
- archagon 3y agoFor you, maybe. For your descendants? History suggests otherwise. Dictatorships are benevolent until they’re not, either because the current ruler gets wacky in the head or their successor has some fresh ideas about projecting power.
- rob74 3y agoI hope that a high security facility which stores tons of cash has something better than Wifi cameras?
- linsomniac 3y agoI think the WiFi jammers aren't for taking out the target's cameras, but random neighborhood Ring cameras and the like.
- ec109685 3y agoStorage is cheap. Cameras should buffer at low frame rate until wifi is restored.
- sschueller 3y agoAll my wifi cameras have an SD slot with an SD in it that records. You would need to climb to each and pull it off to get to it.
