Two questions! 1: How much does it cost to install monitoring in the elevator? 2. Can human urine and dog urine be distinguished by testing?

It's not that simple. Labor cost: Shandong 1 0,000 yuan. The technical difficulty of elevator installation monitoring is not to install a camera, but to follow the line, because the line will hang on the elevator if it is not handled properly up and down. If the line runs badly, something will happen, and it will be troublesome. I advise you not to be safe. If you want to install it, you must also find a regular unit, the camera should be 500 yuan, and the line and so on depends on the distance from the elevator to your home, which is about 100m, that is, 600 yuan, video recorder 500 yuan and hard disk 500 yuan. It also depends on whether the property cooperates. If you don't cooperate, you can't install it at all. About 3 100 yuan, excluding tax.
