Retrofit
Upgrading Old Security Cameras
Analog to IP, Wi-Fi to wired: what can be reused, what cannot, and how the recorder decides it.
Open page
A Wi-Fi jammer floods the 2.4 and 5 GHz bands with noise so nothing nearby can hold a connection. Every camera, doorbell and alarm hub that depends on Wi-Fi to record or to alert you stops doing both, usually without a sound. A camera wired with Ethernet to a recorder inside the house has no radio link to lose: it keeps recording through the jam, through a cut internet line and, on a battery backup, through a power cut. The rest of this page is the evidence from LAPD and the Sheriff’s Department, a test you can run tonight on the cameras you already own, and the design we install so a crew with a jammer leaves with their faces on a hard drive instead of a blank timeline.

| Date | Who | What they said |
|---|---|---|
| March 4, 2024 | LAPD Wilshire Division community alert | Homes burglarized by groups of three or four suspects who use Wi-Fi jammers to interrupt the internet for burglar alarms and cameras as they enter. The crews are known to enter through second-story balconies, seek high-end jewelry, purses and cash, and ransack primary bedrooms while a driver waits as lookout. LAPD’s advice included hard-wiring the alarm system. |
| April 20, 2026 | LAPD Chief Jim McDonnell, with Mayor Bass | After nine break-ins in ten days across Sherman Oaks, the Hollywood Hills, Valley Village, Valley Glen, Sylmar and Toluca Lake, the Chief described organized crews — some international — that place video cameras in front of homes to learn when residents are away, use jammers to disrupt Wi-Fi-based security systems and cameras, and use ladders to enter through second-floor rooms. Targets: high-end purses, safes not anchored to the floor, cash and guns. He also noted Valley Bureau burglaries were down 48% year over year — fewer crews, but capable ones. |
| May 20, 2026 | Sheriff Robert Luna, DA Nathan Hochman, Chief McDonnell | Seven arrests tied to dozens of burglaries in Ventura County, West Los Angeles and Burbank. In at least three cases the crews used hidden surveillance cameras and Wi-Fi jammers. The Sheriff displayed a camera hidden in a box wrapped in artificial turf — a phone, a camera and spare batteries — and said three suspects in a May 1 Ventura County burglary were caught with jewelry, cash and a jammer. His advice: hard-wired systems over wireless ones that can be jammed. |
Two departments, two years, one recommendation: hard-wire it. The rest of this page is how to do that properly, and how to find out first whether your current system would even notice.
A jammer is a transmitter that shouts over the frequencies your devices whisper on. Home Wi-Fi lives at 2.4 and 5 GHz; the devices the crews carry cover those bands, and the same class of equipment is sold for cellular and GPS bands as well. Inside its range, every Wi-Fi device loses its link. Nothing is hacked. The camera simply cannot reach the cloud or your phone, and for most consumer cameras the recording happens on the other side of that link. A cloud-only camera stops recording. A doorbell stops recording. An alarm hub that reaches its monitoring center only over Wi-Fi cannot report. Your phone shows nothing, because the notification never left the house.
What a jammer cannot touch is anything that does not use radio. Copper and fiber do not care about RF noise. A PoE camera cabled to a network video recorder keeps recording. Footage already written to a disk stays on the disk. A wired door contact still reports to the panel. A camera with on-board memory keeps writing to it: Google documents that the Nest camera and doorbell models it lists store up to one hour of events on the device when offline and upload them on reconnection — useful evidence, but no alert while the crew is inside.
Two other parts of the pattern matter for design. First, the crews watch before they act: the turf-wrapped camera the Sheriff displayed was placed on a property to learn the residents’ routine. Second, some crews cut the internet drop at the house, which defeats even a wired camera’s alerts. Neither defeats local recording.
The jammer itself is illegal. Federal law prohibits the manufacture, importation, marketing, sale and operation of signal jammers (47 U.S.C. § 302a(b)) and willful interference with authorized radio communications (47 U.S.C. § 333); the FCC states there are no exemptions for use in a business, classroom, residence or vehicle, and that violators face substantial fines, seizure of the equipment and criminal prosecution including imprisonment. That matters after the arrest. It does nothing for you at 2 a.m.
You do not need a jammer to find out how your system behaves under one. For anything that depends on Wi-Fi, an unplugged router is a fair stand-in. Do this tonight.
| What you saw | What it means |
|---|---|
| Nothing recorded, no offline alert for a long time | Cloud-dependent Wi-Fi cameras. Under a jam you get no footage and no warning. These are the systems the crews are counting on. |
| Footage appeared later, no alert during the outage | On-device memory or a card. Evidence may survive; nobody is told while it is happening. |
| Recorded continuously, panel showed a trouble within minutes | Wired recording with a supervised communicator. This is the target. |
One limit: the router test does not simulate cellular jamming. A jammer that covers cellular bands can silence a cellular alarm communicator at the same time it silences Wi-Fi, which is why the design below does not rely on any single path.
| Architecture | Records during a jam | Alerts you during a jam | Records if the internet line is cut | Records in a power cut |
|---|---|---|---|---|
| Wi-Fi camera, cloud recording (most doorbells and battery cameras) | No | No | No | Battery models stay powered but still cannot upload |
| Wi-Fi camera with a memory card or base station | Usually, on the card — unless the link to the base station is itself wireless | No | Yes, on the card | Battery models only |
| PoE camera cabled to an NVR | Yes | Only if the alert path survives; a cut line means no alert | Yes | Only with a UPS |
| PoE cameras + NVR on a UPS + alarm panel with jam detection and dual-path reporting | Yes | The panel can sound locally and report on any path that survives | Yes | Yes, for hours |
The fix is architectural, not a brand. It is the same design commercial sites have used for years, scaled to a house.
Cameras are half the problem. The alert is the other half, and it depends on the alarm.
Wireless sensors on a single fixed frequency — 319.5, 345 or 433 MHz — can be blocked by the same class of device. Frequency-hopping sensors are much harder to block: PowerG, used by Qolsys and DSC panels, hops across 50 channels between 912 and 918 MHz, 64 times a second, on an encrypted sequence known only to the panel and its sensors. A broadband jammer covering the whole band could still overwhelm it, so treat frequency hopping as better, not immune. Wired contacts on the ground-floor doors and every balcony door remove the radio from the equation entirely.
Then make the panel tell you. On the Qolsys IQ Panel 4, the installation manual lists PowerG RF Jam Detection, Jam Detection (for the 319.5, 345 or 433 MHz card) and Jam Detection Local Alarm — and all three ship disabled by default. Ask whoever installed your panel to enable them and to confirm the event reports to the central station. With local alarm enabled, a jam sets off the siren whether or not any signal gets out.
Finally, the communicator. A panel with both a wired Ethernet path and a cellular path reports on whichever survives. If a crew jams Wi-Fi and cellular but the wired line is up, the report goes out. If they also cut the line, the siren and the jam detection are what you have left — along with cameras that are still recording. We say that plainly because nothing is unjammable at the radio layer; the point of the design is that the evidence and the noise do not depend on radio. We install, service and take over Qolsys panels and provide monitoring month-to-month from $24.99 with no contract.
| Scope | Planning range | What moves the number |
|---|---|---|
| Wired PoE camera system with local NVR, home or small business | $1,500–$30,000+ | Camera count, cable paths in a finished house, recorder storage, UPS runtime, whether existing cable can be reused |
| Alarm monitoring | From $24.99 a month, month-to-month | Dual-path communicator, wired contacts added to balcony and ground-floor doors, panel replacement versus reprogramming |
Every proposal is a written line-item quote with model numbers, the recorder’s storage and retention days, the UPS runtime and the cable listing spelled out, priced after a free on-site assessment. We do not quote a camera count over the phone, because the right count depends on which balcony faces which neighbor’s wall.
Innov8av holds a California C-10 Electrical contractor licence, CSLB #1043428 — the classification has no voltage ceiling and encompasses the low-voltage work the C-7 defines — and a BSIS Alarm Company Operator licence, ACO 7755, the separate licence California requires for alarm work. Both are verifiable in the state’s public lookups. The work is done by our own technicians, carries a one-year parts-and-labor warranty, and existing clients get same-day response.

Yes. Any camera that depends on a Wi-Fi link to record or to notify you stops doing both when that link is jammed, regardless of brand. LAPD described the tactic in a March 2024 community alert, Chief McDonnell described it again in April 2026, and the Sheriff’s Department recovered a jammer from a May 2026 burglary crew. Cameras with on-device memory may keep a short window of footage to upload later, but nothing reaches you while it is happening. Cameras cabled to a recorder inside the house are not affected.
Yes, under federal law everywhere in the United States. The FCC states that manufacturing, importing, marketing, selling or operating a signal jammer is prohibited (47 U.S.C. § 302a(b)) and that willful interference with authorized radio communications is prohibited (47 U.S.C. § 333), with no exemption for use in a residence, business or vehicle. Penalties include substantial fines, seizure of the device and criminal prosecution. The devices are still sold openly online, which is why design, not the law, is what protects the house.
No. A PoE camera sends video over an Ethernet cable to a network video recorder; there is no radio link to interfere with, so recording continues through a jam and through a cut internet line. What a jammer can still affect is the alert: if your only path to the outside is Wi-Fi or cellular and both are jammed, the recorder keeps the footage but cannot tell you in real time. That is why we pair local recording with a UPS and an alarm panel that reports on more than one path and sounds locally on a detected jam.
Only if that feature exists and is switched on. Many panels can detect abnormal RF noise on their sensor frequencies, but it is often off by default: on the Qolsys IQ Panel 4, the installation manual lists PowerG RF Jam Detection, Jam Detection and Jam Detection Local Alarm, all disabled as shipped. Ask your installer to enable jam detection, enable the local alarm, and confirm the event reports to the central station. Wired door contacts and frequency-hopping PowerG sensors are far harder to defeat than older fixed-frequency 319.5, 345 or 433 MHz sensors.
Look at the timeline. A jam shows up as every Wi-Fi device going offline at the same moment and coming back together after the crew leaves, with no motion events in between; a single camera dropping out looks different. Check whether your router logged the outage and whether any camera with on-device memory uploaded clips after reconnection. Give the police the offline and online timestamps — they establish when the crew arrived and left. Report the interference to the FCC through its consumer complaint center as well.
Wired PoE camera systems with a local recorder run from $1,500 to $30,000 and up depending on camera count, cable paths, storage and backup power; most 4–8 camera homes are cabled and finished in one day. Where existing Wi-Fi cameras are worth keeping they stay as extra coverage, and where an alarm panel already exists it can often be reprogrammed rather than replaced. Innov8av’s on-site assessment is free and every quote is a written line-item proposal with model numbers.
