A secondary content camera stream allows you to display both the whiteboard and those present in the meeting at the same time in dual streams.The recommended size of the whiteboard should be between 1.5-2.7 meters in width (5-9 feet), however whiteboards measuring between 1-3 meters in width (3-10 feet) are supported.It is recommended that the whiteboard should be positioned within 3.6 meters (12 feet) of the Jabra PanaCast 50, and no closer than 1.5 meters (5 feet). The optimal viewing range is 3 meters (9 feet).It is important to note the Jabra PanaCast 50 camera consists of three separate lenses, arranged horizontally. The whiteboard MUST be positioned entirely within the view of one of these three lenses.It is recommended to use a standard whiteboard, rather than glass or highly reflective surface. For the best clarity, use black or dark markers to write on the whiteboard.Before a whiteboard can be shared in a video conference, a whiteboard view must be set up using Jabra Direct.To set up a whiteboard view, go to Whiteboard view setup under the Camera settings in Jabra Direct and then click Set up. Jabra Direct will guide you through the process of setting up a whiteboard view.10.3 Share the whiteboard in the main camera viewIf the Whiteboard sharing mode in Jabra Direct is set to Main camera view, toggling the whiteboard view on/off using the camera controller in Jabra Direct or Jabra Sound+ or the remote control will switch between the view of the meeting and the view of the whiteboard.By default, the Whiteboard sharing mode in Jabra Direct is set to Main camera view. This setting can be configured using Jabra Direct.10.4 Share a separate view of the whiteboard in Microsoft TeamsRoomsThe whiteboard view can be shared in Microsoft Teams Rooms as a separate content camera view, which will open a separate video stream of the whiteboard.1.

求职礼仪面试印象50％来自肢体语言
求职礼仪：面试印象50％肢体语言
，是所有人都要经历的求职关。
要跨越这道关卡，个中精髓可不能不掌握。
很多大学生往往会过了关、关就栽在面试上，为了帮助大学生攻破面试关，我们请赫敦管理咨询有限公司的资深职业顾问张建勤女士，教你如何知己知彼，顺利过关。
记者：企业想通过面试了解什么？张建勤：面试是企业“伯乐相马”的过程，他们想“相”的'是德才兼备的人才，所以他们非常关注求职者的综合素质和实际操作能力。
企业的考察涉及到方方面面，除了考察求职者的专业技能这些“硬件”外，更注重“软件”资质，如能力、适应能力、表达能力、说服沟通能力、创新能力、组织协调能力、团队合作精神等。
另外，、敬业精神和人文素质也是衡量的要点。
记者：面试中企业爱用什么招数？
张建勤：目前，企业在招聘过程中，除了传统的面试和笔试外，还加入了管理游戏和情景模拟面试法，这样，对求职者的考察会更加全面。
求职者要学会以不变应万变。
首先，面试前，要仔细分析自己的强项和弱项，扬长避短，明确定位，尽可能详尽了解招聘企业的用
人、企业文化和应聘职位的要求，寻找自己与企业的最佳契合点。
其次，在面试前最好做一次有针对的模拟面试，估计考官会问什么样的问题，自己采取什么策略来回答，这样，基本上能做到心中有数。
记者：参加面试之前要注意些什么？
张建勤：面试时给考官的第一印象很重要，开始的印象往往很可能就决定了面试结果。
大体说来，着装应与企业性质、文化相吻合，与职位相匹配。
不论去什么公司，正装不仅正式大方，而且对别人是一种尊重。
女孩子一定要注重衣着形态的细节，避免穿无袖、露背、迷你裙等装束。
对于初次求职者或刚出校门的大学生，服装就应该以大方简洁为主。
此外，女性求职者在夏季面试时化妆要注意端庄淡雅，细节之处处理好，如头发、指甲等都应干净清爽，显示出干练精神的良好印象。
