Enhance your home security system with these professional-grade warning signs. Each pack includes two durable 12" x 12" octagonal signs crafted from rust-free aluminum, perfect for long-lasting outdoor display. The signs feature bold, UV-protected lettering that clearly indicates audio and video recording surveillance, helping deter potential intruders. Pre-drilled holes allow for quick and easy installation on walls, fences, or gates using screws or zip ties (mounting hardware not included). The weather-proof construction ensures the signs maintain their visibility and effectiveness through rain, snow, and intense sunlight. Each sign comes with protective film on both sides - simply peel off before installation for optimal display. These attention-grabbing security markers are an essential addition to any home surveillance setup, providing visible deterrence while complementing your existing security measures.
