May26 2018: Video surveillance  cameras  have become a necessary fixture in many apartments and  homes.  Many require a technician to rig up.  D-Link  has simplified the technology to create  a  a no -frills do-it-yourself   solution,  that harnesses the home WiFi network. 
The D-Link Mini HD  WiFi Camera model DCS-P6000LH, is a small cylinder less than 10 cms tall, weighing just 60 grams. You can place it anywhere indoors and connect it to a mains  power outlet. Once you have synced the camera to the MyDLink app on  your mobile phone via Bluetooth, you can fully control it from there. The camera  has a 120-degree viewing angle  and a   range of about 5 meters. You can set the sound level to eliminate ambient noise  and it will start  beaming live colour video. It detects   sound or motion and triggers alerts. You can also record manually from the phone.
At night, an infra red lens kicks in to provide monochrome imagery.  I would have liked to see an onboard recording facility using a microSD card. As things stand,  all image files are on the cloud and only accessible through the app.    Still, the dummies approach  to setting up and the  asking price of Rs 2995 , buys you peace of mind  on very reasonable  terms.
