Jobsite Cameras Past, Present, Future
Jobsite Cameras Past, Present, Future How jobsite cameras are evolving in use and capability By David Gaw, Founder, CEO – Sensera Systems Jobsite cameras have become an essential tool for the modern connected jobsite. Understanding these systems and how they support construction best practices is important in today’s ever-expanding jobsite technology array. In this article, we’ll take a look at the evolution of jobsite cameras and how they are impacting the construction industry. WHAT IS A ‘JOBSITE CAMERA’? A jobsite camera is simply a camera that is used on a construction site to provide automated capture of imagery and/or video. Most would also agree that a jobsite camera is one that is network connected to allow for remote viewing and image retrieval. However, there are some more basic devices used on jobsites that record images and video to local storage for periodic manual retrieval by the user. For the purposes of our discussion here we will consider only network-connected cameras, since non-connected cameras are typically not suitable for commercial construction project applications. In addition to the camera hardware itself, a ‘jobsite camera’ typically also incorporates software that provides the following basic functions (at minimum): • Remote configuration of the camera operation • Viewing of images and video • Remote long-term storage of images and video (e.g., cloud-based storage) • Creation of time-lapse videos from individual still images collected at specified intervals BACK IN THE DAY The initial jobsite cameras grew out of early ‘webcam’ applications. A webcam is a camera that is connected to the Internet (or the Web), to allow for remote real-time viewing. -

Bill's Cave Diving Lexicon
Bill’s Cave Diving Lexicon 120 Rule: Noticing from the Navy NDL table that, for certain depths, depth + bottom time = 120 so that the NDL can be determined by subtracting the depth from 120. 200 DIN: Thread depth in a DIN valve and associated pressure (200 BAR) that can be handled. This size (7 threads) allows for a DIN to yoke conversion. 300 DIN: Thread depth in a DIN valve that provides the most secure (9 threads) connection and can withstand 300 BAR pressure. 5 nines pure: 99.999% pure, as in a gas. 50-50: Gas mix of 50% oxygen and 50% nitrogen used for decompression gas. 6351-T6 Aluminum Alloy: Alloy that has had problems with tank ruptures. Absolute Pressure: Total pressure being exerted on a diver At sea level Absolute pressure is 1 ATA and it increases by 1 ATA for each 33fsw (34ffw). ADDD (Air, Duration, Depth, Distance): Limits for dive termination acronym minimum Air volume/pressure, maximum Duration of dive, maximum Depth of dive, and maximum Distance of penetration. ADV (Automatic Deflation Valve, and Automatic Diluent Valve ): Device on a buoyancy compensator that allows for rapid air purging, and device on a rebreather that dilutes the breathing mix. AGE (Arterial Gas Embolism): A lung expansion injury. A condition in which gas bubbles enter the arterial system and cause damage by blocking blood flow to vital organs, most commonly the brain. This is generally caused by air passing through the walls of the alveoli into the bloodstream. Air: A gas mixture of Oxygen (21%), Nitrogen (78%), and other gasses (1%, Helium, Argon, etc.). -
Digital Camera Fully Compatible, Newly Developed S-TTL System
Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera. INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control. Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure. When we start with the history of underwater TTL auto strobe, underwater camera "NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera / housing). A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly NIKONOS type 5 pin electrical wired, automatic TTL flash control is usable with any TTL auto strobe sync connector and NIKONOS V like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync with INON Z-22 strobe cable. Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. -
