I use this Wild camera to monitor a lot. I do not understand the other bad reviews. I own this camera for about a year. You can adjust the sensitivity of the sensor for triggering according to his needs. But I'd rather have a shot too much, than too little. Perfect is that the screen is equal to the entire shooting range can be seen. A potential intruder would not notice at night the camera, since it does not light up. I have a second, the red lights that are much further away must be mounted for this reason that it is not noticed. Because you can install this camera close to the monitored area, you can see everything perfectly, both day and night. Every now and then are a few overexposed images while. I do not think that this is the fault of the camera. The batteries or batteries last long enough. I mostly only 4 there. You can also give pure 8 to ensure a longer monitoring. I replace the battery about 1 time out per month. However, I must say that I have not tried the transfer function via SIM card so far.
