Question: Does it have a delete memory from the SD card option
Document: i have mine set to record constantly during the time slot im not in my office. you have the option to review the clip by pluging it to a tv or popping out the SD card which i decided to do. I mounted it high enough to where i could easily reach the sd card slot and review the footage on a daily basis. its not exactly covert and everyone has asked about it but it gets the job done quite well.
This surveillance camera is exactly what I wanted. It is very easy to set up and can run on continuous, manual or motion detection. Using the SD card it is very easy to replay the video on your computer. Light & non-intrusive.
I discovered this camera when doing a search on google for the meaning of a term, and this camera's manual was posted online and answered the question.I ordered one and have found it an easy-to-use, excellent security camera. Get two memory cards, like 8 GB in size, and when you turn the camera off to take one card out to review it, put the other in and turn the camera back on, so that there's no interruption in coverage.
This system worked great as a discreet camera and recording system. Everyone thought it was just a regular motion sensor with no recording capabilities. All the controls are on the back of the unit and you just pop out the SD card when you want to see what you caught on camera!
At night time there is nothing but darkness because this is not a night vision ready camera. I love that it comes with an SD storage card that you can also view from your laptop computer and the quality is also clear. I tried it on Media Player on Windows Vistas and it worked, but you don't need a computer to playback. The video will play back on a t.v.
I use this product in a retail setting as a Loss Prevention Manager. It is easy to set up and requires only power source if you are not running it off of batteries. The SD card storage makes it easy to review video at any time. The motion setting is very nice and makes it easy to review days of video without having to fast forward through periods when no one is around. Blends easily into its surroundings which makes placement just about anywhere in the store easy to do without drawing attention to it.
This video recording does not work well when I put it in continuous mode.I wanted it to record over the beginning when memory is filled.What happened is it will record and play back properly untill the memory is filled up. After that the screen goes blank (black) every other second. This makes it very hard to view the video. It may miss some action when you need it. It is ashamed such a good product with a bad bug.
Bought this because someone was taking the bulbs out of garage light. Thought I knew... this proved it .. every bit from entering yard to taking bulb. Clear video, gets only the action when in motion mode. Small card holds days of video clips. Setting on next to least sensitive... it got a grasshopper who flew in front of it..  Can't say enough about the qualitiy of this camera.
this item is fine and I don`t like to be required to write to write so many words if I cant just rate item I wont rate any.
great product, speedy delivery, product is as promised. poor instruction set and  if you need to ask a question, you had better be fluent in a foreign language. unable to communicate with foreign service desk...its a shame to have to rely on out of country support for seemingly simple questions. i could not understand a word they were trying to say...
Answer: Select whether to overwrite the recorded SD card or to stop recording when the SD card is full. When you select "Overwrite", the stored video will be overwrittenstarting with the oldest data first.
