The device is not well made. The rotary control and infrared switches are stiff after a short time. You have to pull over again. Picture quality is below average, it is difficult to adjust to the correct focus, because there is no limit for the Focus and a battery eater is the NV also. Whether with or without infrared switching. AND ATTENTION: Who thinks he can operate the device with batteries; forget it very quickly, because even in the manual, it is recommended to use ordinary batteries, because of the fundamental voltage of 1.5 volts. I can only confirm. With battery, the device is running short, no matter how much capacity have the batteries. Even with 2000mA no term of more than about 15 minutes. I highly recommend this device none; also no beginners. Dear spend a little more, or not at all. I have no great pleasure in it, because for me it is just in the cupboard because of the completely lousy quality.
