This is in reply to your 2/16 post Will they see in? The abomination of desolation (image of the beast) will be in the holy place which the worshippers can see inside of according to the design of Jerusalem's temple in the article at Design of Jerusalem's Temple .  Also the worshippers of the image of the beast who are outside the temple all around the world need to see the image of the beast in order to worship it so obviously there likely will be a camera inside the holy place so it can be seen by satellite, cable tv, on your computer or smartphone. Here is another floor plan for Solomon's temple at File:Atria Templi Solomonis, Vaughan 1650.png - Wikimedia Commons

"The two main areas of Jerusalem's temple proper are the Holy Place and the Holy of Holies. The Holy Place contained a seven-branched candlestick, a golden altar on which to burn incense and a table on which showbread (shewbread) was placed. It also had five tables along both the north and south walls of the area."

"The Holy of Holies, when originally constructed by King Solomon, contained the Ark of the Covenant, a flask of manna and Aaron's budded rod."

"Nothing was in the ark except the two tables which Moses put in it at Horeb, when the Lord made a covenant with the children of Israel when they came out of Egypt. (2Chronicles 5:10)."

"But behind the second veil was a tabernacle which is called the holy of holies, containing a golden censer, and the ark of the covenant, which was overlaid on all sides with gold; in which was the golden jar containing the manna, and the rod of Aaron that had sprouted, and the tablets of the covenant; (Hebrews 9:3 - 4)."
