5 Principle of Time of Flight 5.1 Vzense ToF Principle Vzense DCAM710 product principle is based on range-gated imaging ToF solution, and the sensor inside is based on Panasonic CCD sensor MN34906. Fig. 9 5.2 Noise Factors 5.2.1 Ambient Light Because the ToF distance measurement relies on the reflection of light sent out by the camera, any additional light, e.g. artificial light sources or sunlight, may influence the measurement results.
To eliminate the multipath effect, you should: 1. Keep the camera working environment as clean as possible; 2. Avoid the camera be placed at concave forms environment, like corners of a room or inside of a narrow space; 3. Highly-reflective object shall be removed far away from the measurement target; 5.
6 Installation 6.1 Hardware Installation You have read and understood the warnings listed under "Precautions" on Chapter 2; To achieve reliable distance measurements, please follow below tips: Better not using the camera in strong sunlight. If have to, keep the ambient light below 50k Lux. Do NOT place any objects in the scene that are not part of your intended target, especially mirrors or other shiny surfaces/objects. Maintain a stable housing temperature during operation.
PC USB HUB ToF Camera Power Adaptor You can contact the Vzense team (info@vzense.com) for the external powered USB HUB. 6.1.3 100M Ethernet Installation (DCAM550-P Only) In this mode, the camera transmits the required data to host by Ethernet cable, so the power adaptor shall be used. The steps are as below: 1. Mount the camera in an appropriate fixture, e.g. a camera bracket; 2.
6.1.4 POE Mode Installation What is POE (Power Over Ethernet) 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. A power connection, to deliver the electrical power the camera needs to operate.
distribution of network connections is simple and effective How to Upgrade to POE Adding POE to your network is straightforward, and there are two routes you can choose: A POE switch is a network switch that has Power over Ethernet injection built-in. Simply connect other network devices to the switch as normal, and the switch will detect whether they are POE-compatible and enable power automatically.
IEEE 802.3at-2009 standard also known as PoE+, which can provide up to 25.5W, or IEEE 802.3bt-2018 standard also known as PoE++, which can provide up to 60W. Otherwise the product may not work well at long range mode. We can provide optional PoE switch or PoE injector to our customers, please try to contact the sales for the quotation and more information. Steps to Setup PoE Mode As mentioned above, a PoE switch or PoE injector shall be in use to setup the PoE; The steps are as below: 1.
