I must admit it works, I connected 13 cameras and it's been working flawlessly so far and very impressed. Although it comes with a lock to prevent tampering, the lock itself is cheaply made and may not withstand attempted break-ins.
Pros
Power supply was easy to install and a great value for the money
Cons
Although it comes with a lock to prevent tampering, the lock itself is cheaply made and may not withstand attempted break-ins
