Productbeschrijving
De Wireless Input Expander is een conversieapparaat dat detectoren van derden verbindt met Dahua Wireless Hub. Wanneer het alarm van de detector van derden wordt geactiveerd, stuurt de Expander het signaal via RF naar de Hub en meldt de Hub het vervolgens aan platforms. Verschillende alarmtypen kunnen worden geconfigureerd in de DMSS-app, afhankelijk van de typen aangesloten detectoren. De expander heeft een triaxiale accelerometer om te voorkomen dat het apparaat beweegt. Er is ook een invoerkanaal om de sabotagepoort van de detectoren van derden aan te sluiten. De Expander wordt gevoed door droge batterijen en kan ook stroom leveren voor detectoren die erop zijn aangesloten.

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect!
Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air.
The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them!
Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play.
The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing.
I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out.
Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

I have an English Springer Spaniel who is 1.5 yrs. She had this torn apart within the first 5 minutes. This is not for strong chewers!

Great idea poor construction
Color: Large size (7.9"), Color: Large size (7.9")
Great for a dog that likes tug and fetch but the seams are not strong so it ripped fast not from tug but my dogs teeth. I sewed it once since we loved playing with it but it didnt last. Other seams opened. The seams opened in the ball part not by the handles. Less seams and stronger ones would make it 5 star. Im trying a different brand.
