Three questions. One part code. The coil count.
Answer what is in the car and how tall the shaft is; then put in the travel height and we size the job in 90 m coil pairs.
1 · WHAT IS IN THE LIFT CAR?
3 · SIZE THE JOB
Mid-shaft: loop ≈ travel ÷ 2 + 3 m. Shaft top: loop ≈ travel + 3 m. Plus 10 % slack, rounded up to 90 m coil pairs. How the sums work →

QUESTIONS
Choosing — questions
How do I know if the lift camera is IP or HD?
If the camera connects to an NVR with an RJ45 plug it is IP. If it connects to a DVR with a BNC connector it is HD or analog. The camera's label usually says IP / PoE, or HD-TVI / AHD / CVI.
What travel height do I enter?
The distance the car travels from the lowest to the highest landing, not the building height. The lift company has it on the drawing; roughly 3 m per floor for residential buildings.
Why 90 m coil pairs?
Lift jobs consume cable in pairs — two lifts in a bank, or a run and its spare — so Channeltech supplies matched 90 m + 90 m coils. One pair typically serves two lifts.
