- Too low viewing angle
-definition video and too weak picture (640x480)!
- Not adjust the brightness of the screen through the eyepiece, it is too strong default, it takes at least 10 minutes to find a partial vision of the eye used and 1 hour after I had discomfort at eye level
- Passing night vision / color depending on the use of the torch, there ''s no separate button (must put your hand over the torch, not practice).
- No on / off button to the infrared torch independent selection buttons intensity level, you have to go through all the stages from off to maximum, not practical.
- No way to format the SD card internally to set date time year (picture blocked in 1999, blocked video 1979), not stored to the numbering of internal flash (for external formatting the numbering starts over from where duplicates) ... in fact there was almost no features and no menu!
- Transfer from the camera to PC very very slow (less than 1 MB / s !!), even with a good map 10 category. it must pass through another device or a card reader to have proper rates of several Mb / s.
- Fixed zoom to 5, can not be adjusted from 1x to 5x, the device is useless to move, or to easily locate objects when they are too close.
- Infrared torch too close to the visible. It is easy to mark 40 meters the person wearing the device when she looks at you!
after 3 days of tests covered both by night, clear night, for me there are too many imperfections in the product design, not enough performance and functionality, all this spoils the use of this device, a simple apn € 100 has 10 times more functionality and performance that Bresser 1877300. Rest night vision, due to the purchase in the beginning, but it is lightweight advantage and it does not justify the current price, because it is a digital technology that is simple CMOS sensor or CCD + infrared torch, no amplifier as on the real night vision devices
suddenly I returned I could not keep it.
