I tried to use these in my apartment, and they were fairly spotty. On live viewing, it would sometimes be choppy/laggy. Even on the movement clip recordings, it would be laggy at times. Luckily, this camera was within the same room as my router, so the 2.4GHz connection was fairly stable to this camera (I live in an apartment complex, so 2.4GHz connections can get interfered with a lot). As for my other Zmodo cameras further away from my router, they did not work well AT ALL. For the price, this camera is a great option if you don't live in a dense area, and you aren't placing it very far from your wireless router. I have since returned this, and picked up 2 Arlo Q's, and they work MUCH MUCH better. They communicate over 5GHz WiFi, and I have no issues with them anywhere in my apartment (many many more features too).
