Bests & Worsts Reviews from Amazon

I had considerable concerns about this product based on a large number of negative reviews. However, after reading 2-3 in-depth reviews that were positive, I purchased the doorbell system. I experienced several problems that were NOT a fault of the product and after several hours, contacted support for assistance. A summary of MAJOR challenges are outlined below. 1. If you have a very simple home network and doorbell, there should be NO problems watching the Zmodo videos and following the instructions. 2. GUEST NETWORK - if your system allows for a guest network, TURN IT OFF! TURN IT OFF! 3. Android phone - you may have problem entering a camera NAME. Just enter a couple of characters and edit the name after the install is complete. 4. Zmodo Knowledge Base - ZINK Troubleshooting Guide - PRINT and read very carefully. The following items were important on my installation: Ensure NO spaces in SSID (your network name) and at least SIX characters, Security must be WPA or WPA2, Network must be 2.4 GHz, Prior to connecting to the Zmodo device network "ZMD_SAP", you MUST "forget your network" which will prevent your phone from accessing your home network automatically. ZMODO SUPPORT: Yep, lots of complaints here regarding connect/hold time which is understandable during heavy holiday season purchasing and other factors. However, don't give up! Put your phone on speaker, do something else and wait in line. I was connected to customer service agent JARED and he provide an EXCELLENT customer service experience. He was very empathetic, understood the product extremely well, and logically went through each step in the installation process. My stealth GUEST network was the culprit and he correctly identified the reason my camera would not connect to the correct home network. THANK YOU to Zmodo support Carrie and Jared. No, I am not a seller's employee - I am a retired computer services manager with years of dealing with difficult customer situations and these service agents exceeded my expectations.
