A fixed 2.8 mm lens is right where the camera is close to the subject; a varifocal lens pays off where distance or scene width is uncertain. The arithmetic, the labor side and the CASE varifocal SKUs as printed.
Half a day on the bench is a day less on site: firmware, passwords, the IP plan, channel names, recording and retention, a CASE Connect check and a packing list, with the bench-test checklist inline.
Why a dome goes milky at night and soft by day: the foam light shield and bubble seating, tilt limits, nearby surfaces that bounce IR back, a forced night test before you leave, and cleaning without scratching the bubble.
How to cover a parking lot from existing light poles and building corners instead of trenching: pole ownership and power, PoE reach, corner mounts, a stitched 180° camera in place of two, and when a wireless bridge is justified.
Ceiling type decides the mount: tile bridges and independent support on drop ceilings, anchors for drywall and concrete, clamps and strut on metal deck, pendant mounts for high ceilings, and plenum-rated cable above all of them.
Water enters a camera through the connector, not the housing. How to shape a drip loop, size a gland, use the junction box, choose sealant and UV-rated cable, with an inspection checklist.
A labeling and documentation standard for camera installs: one ID per cable and port, an NVR port schedule and IP plan on one sheet, as-built photos and a handover file, with the template inline.
Why pole-mounted PTZs are the first casualty of a storm, what the CASE PTZ spec pages actually print as protection, where inline surge protectors and grounds go, when fiber is the right isolation, and what to document for the customer.
What to walk, photograph and measure on a camera site survey, the network, power, compliance and privacy questions to ask, how the answers become a bill of materials, and a survey form to copy into your own template.
A three-stage checklist for camera installs (pre-install, install day, commissioning) plus a handover list and a commissioning report template you can copy into your own job folder.
