Calculators

Field estimates for the truck and the mechanical room. Results are starting points—verify against manufacturer data and local code.

Power

Size copper runs, check remaining length and load, and compare a field voltage reading.

AC to DC Conversion

AC secondary to DC, and the RMS that produces a required DC.

UPS and Backup Battery

Watt rating and battery energy for rack equipment, or amp-hours for a 12 or 24 VDC panel.

Access control

Low Voltage Load

Size access-control supplies and battery standby from device lists.

Video

Video Bandwidth

Rough camera bitrate and uplink needs for recording and viewing.

Retention-driven storage and RAID drive counts for NVR/VMS.

Field of View and DORI

Scene width, pixel density, and IEC 62676-4 detect through identify distances.

Pathways

Check fill percent against NEC limits for EMT and PVC pathways.

Cable Tray and J-Hook

Tray and J-hook fill by area and by weight, and which limit is reached first.

Fiber

Fiber Link Loss

Link loss by fiber, wavelength, connectors and splices, checked against a transceiver budget.

Networking

Subnet and CIDR

Usable range and a device assignment list from the IPv4 block IT supplied.

PoE Budget and Distance

Switch watt budget, class reservations, remaining power, and the 100 m channel.

Reference

EOL resistor color code

Bands for a value on the truck, or the value of a resistor already in the can.
