The Tilta HDA-ESC-DM-45 is a 4.5" electronic suction cup with integrated dovetail clamp, specifically engineered for the Hydra Alien Pro car-mounting system. Featuring real-time air-pressure monitoring, an automatic high-performance vacuum pump, a 2000 mAh battery with up to 14-hour runtime, and a rated 44.1 lb (20 kg) vertical load capacity, it delivers rock-solid, active adhesion to vehicles or any smooth surface for safe, high-speed cinematic tracking shots.

Built for professional vehicle exteriors, the HDA-ESC-DM-45 combines industrial-grade vacuum technology with smart electronics: a sensor checks pressure thousands of times per second and instantly activates the silent motor to maintain perfect vacuum. The top dovetail clamp locks directly onto any Hydra Alien Pro dovetail plate (or standard mini-dovetails), while the base offers additional 1/4"-20 and 3/8"-16 threads for alternative rigging. A bright status screen shows real-time pressure, battery level, and pump activity. The 2000 mAh lithium battery powers the system for up to 14 hours and recharges quickly via PD USB-C.
