We are getting a new fiberglass door, and didn't want to deface it just to install an old-school peephole. This enables us to easily see who's at the door--in addition to monitoring our front patio for deliveries and backyard gate while we are away. Setup was simple (other than running the power to them through the attic) and they "booted" up and work flawlessly. Well worth the money.
Bought this to protect my car as it was just vandalized. System works just as advertised ( and some aspects better than) Only issue I have is the occasional signal loss and no back up for the monitor when moving it to another power source. Everything else is great. Highly recommend as this is really a great value.
Only been using it for one day but the sample videos Ive made seem like decent quality. No detailed instruction booklet enclosed...just a "quick start up guide".... looked up details online BUT it is pretty intuitive to set up. Hope it lasts!
