    Synology Announces DiskStation DS1825+ and DS725+ NAS Systems


    Synology has unveiled two additions to its DiskStation lineup—the DS725+ and DS1825+—which offer two and eight drive bays, respectively. The new 25 Plus series models offer 2.5GbE networking, support SATA SSDs and HDDs (both 2.5″ and 3.5″), and feature M.2 NVMe slots for use as cache.

    Like the DS925+ and DS1525+, the new models can be upgraded with the company’s DX525 expansion unit. You can add a single expansion unit to the DS725+ or two expansion units to the DS1825+. Calculated using 20TB drives, you get up to 40TB of storage with the DS725+ or 140TB with added expansion; and up to 160TB with the DS1825+ or an impressive 360TB with the added expansion. That’s a serious number of photos and videos!

    One caveat to consider when investing in these new 25 Plus series models is that Synology says complete functionality will only be available with Synology-branded drives—a proviso that the company says ensures the most reliable performance. This isn’t a huge deal if you’re using HDD drives, since Synology’s drives are competitively priced, but if you want to go the solid-state route, Synology SDDs are rather expensive compared to those of its competitors. (Non-certified drives can technically be used in the new NAS systems, but users that choose to do so will lose certain software- and firmware-related functionality.)

    The Synology DS725+ and DS1825+ will retail for $520 and $1,150, respectively—yes, that’s without any storage drives!

  • Are LiDAR Systems on Cars Destroying Camera Sensors?

    Are LiDAR Systems on Cars Destroying Camera Sensors?


    There’s a bit of growing unrest among photographers on whether LiDAR systems that are being fitted in new cars are actually capable of destroying camera sensors.

    LiDAR systems are used by car manufacturers with self-driving cars to build 3D models of the surrounding environment so that the car knows where to steer.

    A thread on Reddit talks about how a car photographer had several cameras destroyed after doing a car photo shoot.

    What seems to be happening is that the laser from a LiDAR is too much for certain camera sensors to handle, and results in irreparable damage to those sensors.

    As you can see from the video below, it certainly seems to be the case that LiDARs are destroying sensors in some scenarios.

    But what is the nuance here?

    In the first video, it is unclear what type of camera is being used to show the damage being done.

    You will notice in the second video that the gentleman has trouble trying to damage his phone camera, whereas the LiDAR does damage the older iPad camera sensor.

    Either way, it is clear that this doesn’t happen on every camera sensor every time it’s exposed to LiDAR lasers.

    It also becomes clear from the comments that using a filter such as a UV filter will not protect your camera sensor from such damage. UV filters are designed to protect from ultraviolet light around 400nm, whereas LiDAR light at around 905nm to 1550nm will pass straight through such protective filters.

    According to the gentleman in the second video, when he contacted Volvo about their LiDAR and the potential damage to camera sensors, they responded that they were aware of the situation and that people should be cautious about using cameras around LiDAR.

    Where do you think things go from here?
