Addendum: We tore down this camera to check its SoC. This camera uses a Huawei HiSilicon chip, unlike most Hanwha cameras that use Hanwha's own Wisenet chips. Graphic:
Huawei has been the subject of significant security concerns around the globe and is part of the US NDAA ban, along with Dahua and Hikvision.
Hanwha responded to IPVM:
Hanwha takes comprehensive, rigorous and thorough measures to develop, test and inspect all Hisilicon chips before they are used in its cameras. This includes developing and compiling source code including Open Source elements and those provided by Hisilicon. Hanwha also use its own chip mounting technology to fully control the production process, and to prevent placement of unintended components on any Hanwha Techwin circuit board. Production is out of Hanwha’s facility in Vietnam, by Hanwha employees. Finally, Hanwha conducts rigorous penetration testing by a reputable third party white hacker. Results are used to refine the firmware and to address any discovered vulnerabilities.
Is there a reason why color night performance is not tested? We have been using the DS-2CD2xx5FWD-I line of cameras from Hikvision specifically for their Darkfighter technology. We would consider other brands if they had similar color low light abilities. Otherwise, it’s just another camera in a crowd of IR based low light, which anyone can do.
Looking at the spec sheet, Hanwha claims 0.18lx @ f2.0 for minimum illumination in color mode. Darkfighter units are rated much lower than that, but ratings are not always very reliable/comparable. I would rather see a test that I could rely on.
An important thing to note. While the L series camera has more LEDs, it uses the older style Through-Hole Technology (THT). These LEDs are more directional and create a halo effect with less even edge-to-edge lighting. The Q series (and all other current Hanwha models) use the newer Surface Mount Technolgy (SMT) style LEDs, which are more powerful and capable of better control and power management.
This is due to the design of SMT/SMD as well as the lack of a "dome" on top which can focus the light only to the center.
I always recommend using SMT LEDs vs THT. The performance is huge.
Thus, the Q series camera has fewer IR LEDs, it can actually do more (outperform) with fewer LEDs.
