Dahua WizSense 3 Series Network Camera greatly saves on bandwidth and storage space through its AI Coding technology. Driven by its advanced deep learning algorithms, the camera supports intelligent functions such as perimeter protection, smart motion detection (SMD), Quick Pick, and AI SSA (AI Scene Self-adaptation), making it easy and convenient to use. Starlight technology and its large aperture lens also allow the camera to produce clear, vivid images even in poor lighting conditions.
Features
- SMD 4.0 - Dahua Smart Motion Detection technology works with intelligent
algorithms to classify targets that trigger motion detection alarms. It filters out objects that are not targets, such as small and large animals, to avoid triggering false alarms. With an AI NVR, Quick Pick technology becomes available, allowing you to easily search for and pick out human and vehicle targets from SMD event videos, prioritizing the highest matches. - AI SSA - Dahua AI Scene Self-adaptation (AI SSA) adopts deep learning algorithms to detect environmental conditions, such as rain, fog, backlight, low light and flicker, to adjust the parameters of the image to suit the conditions, ensuring that clear images are always produced.
- Smart H.265+ & Smart H.264+ - With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission.
- Perimeter Protection - With deep learning algorithm, Dahua Perimeter Protection technology can recognize human and vehicle accurately. In restricted area (such
as pedestrian area and vehicle area), the false alarms of intelligent detection based on target type (such as tripwire, intrusion) are largely reduced. - Protection (IP67, IK10, Wide Voltage) - IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can work normally after soaking in 1 m deep water for 30 minutes. IK10: The enclosure can stand the punch more than 5 times from a 5 kg hammer falling from a height of 40 cm (Impact energy is 20J). Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.
- Cyber Security - Dahua network cameras employ a series of security technologies,
including security authentication and authorization, access control protocols, trusted protection, encrypted transmission and encrypted storage. These technologies improve the camera's defence against external cyber threats and prevent malicious programs from comprising the device.

Best Book on Improving Communication in Relationships
Format: Paperback
Such a helpful book, with concrete tips for improving communication in relationships. I find myself returning to this book whenever things become challenging in a relationship. I also attended a retreat based on the book’s teachings. Incredibly helpful.

Interesting, but not empirically validated, and written explicitly for straight people (why?!)
Format: Kindle
This one’s the 500-pound gorilla of the healthy-couple self-help genre, with thirty years in print, scores of Oprah appearances by the authors, thousands of therapists practicing the Imago framework.
The main thing that I need to tell you about this updated edition, from the year 2019, is that it does not mention or acknowledge the existence of queer or same-sex couples even one time. In fact, it really doubles down on the husband and wife stuff, takes gender roles pretty seriously, which is not a thing I realized we did anymore, except as a joke. Anyway, talking only to straight people is not too relevant to my interests, and while the conservative Christian viewpoint is pretty subtle in the advertising, just be aware of that PROBABLY NOT ACCIDENTAL omission going in, queer friends.
(This is made even more impressive by the fact that the heart of the Imago approach is based on childhood trauma, about the ways in which our parents caused us to suppress or hide or ignore parts of ourselves in order to be accepted and loved. Just let that sink in, because I’ve been reading this book for the past week and I am still reeling from the irony that people who have been thinking for the past three decades about the ways that parents cause trauma to kids by failing to accept parts of them have missed the VERY OBVIOUS AND RELEVANT EXAMPLE of queer folks.)
That aside, for me the book was a mixed-bag of some interesting and provocative ideas (I’d put these in the category of poetic notions, or interesting narrative ideas), alongside some really kooky 20th century neo-Freudian stuff (rooted in part in Freud’s theory of repetition compulsion.) I’m no fan of Freudian approaches, and after I started this book, I decided to see how empirically-validated this Imago approach is: based on what I found, there seems to be basically no evidence that this therapy is effective.
Am I glad I read it? I think so?? It was thought-provoking, with the pretty significant grain of salt that there’s not much evidence to support that Imago therapy is much better than doing nothing at all. Also, I feel a little gross giving my money to relationship experts who (in 2019!!)) won’t even acknowledge the existence of queer people, even when doing so would obviously strengthen their core arguments and provide better examples than some of the meek ones they give.

Great book!
Format: Paperback
I read this once through on my own and picked up a lot of great wisdom. Now my spouse are reading it together so we can answer the questions together. I'm excited for thought provoking discussions on raising our future child.
