Hello There, I bought the set 2 weeks ago. I was interested what happens in my garden day and night. And I do not need pictures in FullHD and should remain within reasonable limits as regards the price. I took the set in 15 minutes with the APP TVAC18000 in operation. The quality of the pictures is fine, with rapid jerky movement but a bit (high resolution and quality). Here, however, the quality can be reduced to achieve a higher frame rate. The Night Vision by IR LED's is also quite useful. The motion goes considerably further than those displayed here 5 meters. I'd rather start from 10 meters, when for example a passing cat takes the camera on reliably. 3. A camera I have installed at the front door. With an old HTC I look over the APP permanently on the camera, it works absolutely reliable. Access to the live image from the mobile network works perfectly, but this UMTS or LTE is required, otherwise it is rather a still image. I store the recordings on the included microSD card. Here, a ring buffer is used, ie I do not have to take care of the memory management. The card is filled, and then overwritten. In addition, even an alarm when motion is detected to be turned on. The news comes then via push message through the app on your smartphone.
