What it is

The MS-5 Genuine Ultrasonic Collar is a specialized key designed exclusively for High Tech Pet Power Pet Doors. Unlike standard RFID tags that rely on proximity alone, this device uses patented directional ultrasound to communicate your pet's specific movement toward the door. This sophisticated signaling prevents the door from cycling unnecessarily when your pet is simply lounging nearby or walking past the entrance, ensuring a more secure and energy efficient home environment. The unit is built to withstand the rigors of an active pet lifestyle, featuring a fully waterproof housing that handles swimming and heavy rain without failure. While the technology inside is complex, the form factor remains lightweight enough for cats and small dogs, yet durable enough for large breeds. By choosing this genuine hardware over generic alternatives, owners maintain their door's performance warranty and ensure the four way access control system functions as intended.

Ravvy AI insight

While ultrasonic technology is superior for preventing false triggers compared to basic RFID, it requires line of sight and consistent battery health to maintain range. We recommend this specific MS-5 model because it includes two spare batteries, which is critical since ultrasonic transmission consumes power faster than passive sensor tags.

Ensure the transmitter points forward on the pet's neck for the best directional signal. The strap should be snug but allow two fingers to fit underneath for comfort.

Ownership tips

tip

Battery Testing

Test the signal strength weekly by walking the collar toward the door by hand. If the activation range drops significantly, it is time to swap in one of the included spare batteries.

care

Cleaning the Housing

Wipe the ultrasonic transducer area with a damp cloth to remove mud or debris. Obstructions on the sensor face can muffle the signal and reduce the door's response time.
