The SNC-EM630 and the SNC-VM630 belong to the Sony line of 2-megapixel high-performance dome IP camera systems. Both of them give users a sophisticated set of tools that make them ideal for surveillance in low-light conditions. They also come with zoom and focus lenses that can be adjusted manually or remotely, from a computer. These systems work best in indoor locations that do not require a wide field of vision, like offices or hallways.
The SNC-EM630 represents a relatively economical camera system, offering a basic but sophisticated surveillance option to fit a budget. The SNC-VM630 costs more but gives you a wider range of features.
Intelligent Surveillance Software
DEPA Advanced Intelligent Video Analytics gives you the power to trigger alarms based on a set of preset rules. These analytics include face detection, to detect when a human face has entered the field of vision, line crossing, to discern when a set boundary is breached, object removal, to discern when something has been taken from the field of vision, or object left behind, to discern when a new object has been left in the field of vision.
Video Quality
These two camera systems offer a 2.1-megapixel image with a maximum resolution of 1920 x 1080. The SNC-EM630 comes with a frame rate of 30fps, while the SNC-VM630 features a superior image with 60fps. True day/night functionality allows it to adjust to lower or higher levels of light, delivering the best image throughout the day.
XNDR noise reduction technology serves to offer sharper images with little motion blur under low illumination. Image stabilizers help to minimize the effect of camera shaking upon the captured image.
Extras and Peripherals
Either camera can be paired with indoor wall mount brackets, pole mounts, and gooseneck wall mounts to accommodate various needs.
The SNC-VM630 gives you additional functionality, including two-way audio, alarm output, IO connections, and an SD card slot to allow for local video storage for when the network is down.
Protective Features
Both of these IP camera systems are available in outdoor or vandal-resistant versions, with optional features for protecting the camera against the elements and against tampering.
