Review on WALI TC-W2 Bullet Dummy Fake Surveillance Security CCTV Dome Camera with LED Light - Indoor/Outdoor | 2 Packs, White by Radney Taala

When a battery is added, the indicator flashes continuously. I don't know how long the batteries will last, but probably not long enough. If it flashes maybe every 10-15 seconds but it keeps going uninterrupted. Might still act as a deterrent because we also have real cameras so we can keep thieves guessing. And if none of them work and we end up at home, I have a permanent repeller for them too.
