Si vous êtes du genre à avoir passé des heures sur Half-Life 2 à vous en retourner les paupières (et je sais que vous êtes nombreux), oubliez tout ce que vous pensiez savoir sur la stabilité légendaire du Source Engine. Car figurez-vous qu'un bug totalement improbable vient de refaire surface grâce à Tom Forsyth, un ancien de chez Valve, et c'est clairement un truc de fou, vous allez voir...

Tout commence en 2013. À l'époque, Valve bosse sur le portage de HL2 pour le tout premier Oculus Rift (le fameux DK1 qui nous donnait tous envie de vomir au bout de 5 minutes). Pour tester la VR, ils se disent que le mieux, c'est de reprendre un bon vieux classique. Tout se passe bien jusqu'à ce que Tom Forsyth reste bloqué dès l'intro du jeu, juste après la séquence de la canette. Un garde Barney censé vous ouvrir une porte reste planté là, et la porte refuse de bouger. Coincé. Rideau. On ferme.

Le truc qu'il constate alors, c'est qu'en recompilant le code source original de 2004, le bug est là aussi ! Pourtant, personne ne l'avait jamais croisé en neuf ans. Du coup, l'équipe a cru à une sorte de malédiction ou à un bug qui aurait voyagé dans le temps pour infecter l'original. (si si...)

Mais après une journée de spéléologie dans les outils de debug, ils ont fini par trouver le coupable : l'orteil d'un garde PNJ ! Le pauvre couillon était placé un millimètre trop près de la porte et en s'ouvrant, la porte tapait dans son pied, rebondissait et se verrouillait. Imaginez un peu la vie du gars, à se faire matraquer l'orteil depuis +20 ans sans pouvoir crier ou se décaler d'un millimètre... Dur !

Mais alors pourquoi ça marchait en 2004 et plus en 2013 ?

Hé bien la réponse tient en deux mots qui vont rappeler des souvenirs aux plus geeks d'entre vous : ✨ virgule flottante ✨.

Car en 2004, le jeu tournait avec les instructions x87 (80 bits de précision, un beau bordel hérité de l'époque)et en 2013, avec le passage au SSE (32 ou 64 bits), les calculs physiques sont devenus plus "stricts". Dans les deux versions, la porte tape l'orteil mais avec le x87, la micro-rotation infligée au garde suffisait à dégager son pied juste assez pour que la porte passe au millième de seconde suivant. Avec le SSE par contre, le garde pivotait un chouïa moins loin... et paf, collision, porte bloquée !

C'est encore une preuve que même dans un chef-d'œuvre comme Half-Life 2, tout ne tient qu'à un orteil et quelques bits. D'ailleurs, si vous voulez vous replonger dans l'ambiance, sachez que Half-Life a fêté ses 25 ans récemment avec une belle mise à jour, et pour les nostalgiques de la VR qui veulent souffrir avec style, le driver VorpX permet toujours de faire des miracles. Ce serait dommage de passer à côté !

Allez, je vous laisse, je vais vérifier si mon gros orteil ne bloque pas ma porte d'entrée.

New IP Cameras and AI Surveillance for NAS Coming Soon

UGREEN has outlined a SynCare lineup of IP surveillance devices that focuses on edge processing, on-device multimodal AI detection, and local recording, rather than a cloud-first model with recurring fees. The range, shown publicly around CES 2026, includes indoor cameras, an outdoor camera, and a video doorbell, with a separate Smart Display hub positioned as an optional central screen and Wi-Fi hub. UGREEN’s messaging also points to broader ecosystem ambitions, including compatibility with local storage today and later integration with UGREEN NAS systems in H2 2026 for longer retention, organization, and multi-camera management.

What is the UGREEN SynCare Series

The UGREEN SynCare Series is a planned smart home surveillance lineup built around IP cameras and a video doorbell, introduced as UGREEN’s entry into home security hardware. The set includes 2 indoor camera variants (ID500 Plus and ID500 Pro), an outdoor bullet-PTZ camera (OD600 Pro), and a video doorbell (DB600 Pro). UGREEN has positioned the range for release in H2 2026, with pricing expected to be disclosed later, including around IFA 2026. A defining theme across the range is edge AI, with UGREEN describing on-device multimodal recognition that can classify people, pets, and other events, and then translate those detections into more descriptive alerts. The intent is to reduce reliance on cloud processing and minimize subscription requirements, with an emphasis on local storage and privacy controls. In practical terms, the cameras are presented as doing much of their analysis at the camera level, while still supporting broader system coordination. UGREEN has also described SynCare as an ecosystem rather than isolated devices, including cross-camera awareness and a Smart Display D500 that can act as a central monitoring screen and connectivity hub. The system-level features described include event sharing between devices, multi-zone monitoring outdoors, and “risk-based” escalation behaviors such as warning lights and alarms. While the full surveillance software stack has not been fully detailed yet, UGREEN has repeatedly referenced NASync support and later NAS integration as part of the intended trajectory for the platform.

UGREEN SynCare Indoor 2K Cam ID500 Plus

The SynCare Indoor Cam ID500 Plus is positioned as the lower resolution indoor model in the lineup, pairing a 2K-class image sensor with dual-band Wi-Fi and on-device multimodal AI for identifying common subjects such as people and pets, along with event-based detection. It is described as using local recording rather than mandatory cloud storage, with support for internal SD-based storage and stated compatibility with UGREEN NASync systems for users who want longer-term retention or centralized storage outside the camera itself.

UGREEN SynCare Indoor 4K Cam ID500 Pro

The SynCare Indoor Cam ID500 Pro is the higher tier indoor option and is described with 4K capture plus motorized pan and tilt for coverage beyond a fixed viewpoint. UGREEN also associates this model with an f1.0 aperture and a color-focused low-light mode branded as UltraColor Night Vision, alongside on-device multimodal recognition intended to classify subjects and incidents for more specific notifications. In system descriptions, it is also linked to cross-camera awareness and risk-based alert behavior when used alongside other SynCare devices.

UGREEN SynCare Video Doorbell DB600 Pro.

The SynCare Video Doorbell DB600 Pro is the entry-point camera in the range that is designed specifically for front-door coverage, using a dual-camera setup to capture both a primary view and a lower secondary view for head-to-toe framing. UGREEN positions it for identifying visitors and deliveries, with multimodal AI intended to separate people, pets, and packages into distinct detection types so alerts can be tied to what is actually happening at the doorstep. In the pre-release descriptions, it is presented as a Wi-Fi doorbell solution rather than a PoE device, and availability is expected in H2 2026.

UGREEN SynCare Outdoor PoE Cam OD600 Pro

The SynCare Outdoor Cam OD600 Pro is the exterior-focused model and is described as a triple-lens bullet-PTZ design that combines a fixed wide view with pan-tilt coverage for tracking activity across a larger area. UGREEN has highlighted 18MP imaging, optical zoom, and 24/7 continuous recording, alongside on-device multimodal AI aimed at differentiating people, vehicles, and pets for more targeted alerts. Unlike the indoor models and doorbell, this camera is also presented with Power over Ethernet support in addition to dual-band Wi-Fi, and UGREEN has described multi-zone monitoring behavior that escalates from capture and notification to lights and audible alarms as a subject moves closer.

The SynCare Smart Display D500 is described as a central control screen for the SynCare lineup that can aggregate camera feeds, show events in real time, and act as a connectivity hub within the home. UGREEN’s positioning suggests it can simplify monitoring when multiple cameras are deployed, while still keeping core features available through the mobile app without requiring the display for functionality. In other words, it is presented as an optional hardware dashboard rather than a mandatory controller for the cameras.

Included Surveillance Services

SynCare is presented as more than basic video capture, with UGREEN describing a set of edge AI and ecosystem features intended to reduce irrelevant alerts, improve low-light usability, and coordinate behavior across multiple cameras. The emphasis is on on-device recognition and local storage, with additional automation features that depend on having more than 1 SynCare device in the same setup.

• On-device multimodal AI recognition for people, pets, vehicles, packages, and general events

• Human-language style alerts that describe what was detected rather than only motion notifications

• Behavior analysis concepts, with examples such as identifying an approaching stranger by appearance

• UltraColor Night Vision and low-light color correction for clearer nighttime footage

• Local recording with no mandatory cloud subscription, including SD-based storage support

• Cross-camera awareness, where one device can trigger announcements or actions on another

• Multi-zone outdoor monitoring with escalating responses such as recording triggers, warning lights, phone notifications, and audible alarms

• Smart risk-based alerts that vary response intensity based on proximity or severity

UGREEN NASync Support?

UGREEN has positioned SynCare around local recording and on-device processing, but has also repeatedly tied the cameras to its NAS ecosystem through references to NASync compatibility and later integration. The implication is that SynCare can operate as standalone devices first, then gain more centralized storage and management options when paired with a UGREEN NAS.

What is directly stated so far is limited but consistent: SynCare devices are described as supporting local storage without mandatory cloud fees, and multiple product descriptions refer to supporting or being compatible with UGREEN NASync. In the broader SynCare overview text, UGREEN also links privacy to encrypted local storage via NASync, which frames the NAS as a destination for retained footage rather than a required cloud account.

What remains undefined is the software side of that relationship. In your video, the open question is whether UGREEN’s eventual surveillance platform will be limited to the newer AI-focused NAS models or will also be delivered to the wider NAS lineup, and there are no concrete details yet on what the camera to NAS workflow looks like in practice. Until UGREEN publishes the surveillance application details, the NAS portion should be treated as planned ecosystem support rather than a fully specified NVR feature set.

UGREEN’s newest AI NAS hardware is relevant mainly because it suggests where the company expects heavier workloads to land, including multi-camera retention, indexing, and any future server-side analytics. The iDX6011 and iDX6011 Pro, as described, combine high-end Intel Core Ultra processors, large LPDDR5/x memory configurations, dual 10GbE networking, and up to 196TB raw capacity across 6 SATA bays plus 2 NVMe slots, which is a plausible foundation for sustained recording and longer retention, even if the cameras themselves handle primary detection at the edge.
