Page 17: Principle Of Time Of Flight
Broadcast: Connected: Upgrading: 5 Principle of Time of Flight Scope of remote sensing technology · Presence or proximity detection, where the absence or presence of an object in a general area is the only information that is required (e.g., for security applications). This is the simplest form of remote sensing;... -
Page 18: Direct Time Of Flight
5.1.1 Direct Time of Flight In the direct time-of-flight measurement method, a discrete pulse is emitted and one or several timers are used to measure the time difference between the emitted pulse and the return echo, based on threshold detection. This time difference can be directly converted to a distance, based on the following equation:... -
Page 19: Range-Gated Imaging Tof
The difficulty in implementing the direct time-of-flight measurement method resides in the time intervals to be measured. In order to resolve a distance to centimeter-level accuracy, the required accuracy for the timers is 67 ps. Implemented in digital logic, this would require a 15 GHz clock speed, which is obviously not practical. Therefore, various time-to-digital conversion methods are typically used. -
Page 20: Vzense Tof Principle
5.1.4 Vzense ToF Principle Vzense DCAM800 product principle is based on range-gated imaging ToF solution, and the sensor inside is based on Panasonic CCD sensor MN34906. -
Page 21: Noise Factors
A strong ambient light may affect the accuracy and precision of the depth data, the Vzense DCAM 800 is suggested to in user below 50K LUX ambient light. 5.2.2 Multipath Propagation Based on the principle of ToF, Multipath effect may happen when the light reflected more one once. -

1. Mount the camera in an appropriate fixture, e.g. a camera bracket; 2. Plug the M16-8 socket end of the Ethernet cable (VZENSE-LAN-8P-A) into the M16-8 LAN socket jack at the back of the camera, and plug the other RJ45 end into the Ethernet port of your host processor;... - Page 23 Power over Ethernet (POE) is a technology that lets network cables carry electrical power. For example, a digital security camera normally requires two connections to be made when it is installed: A network connection, in order to be able to communicate with video recording and display equipment.
- Page 24 Midspans are available as multi-port rack-mounted units or low-cost single-port injectors. For Vzense DCAM800 camera, the POE Switch or POE injector needs to support IEEE 802.3at-2009 standard also known as PoE+, which can provide up to 25.5W, otherwise the camera may not work well at long range mode.
