I purchased 2 sets of 4 Cuddelink cams off ebay when they had a lower price special of 4 for 569.00. I was a little disappointed when received and the camera housing has no cable locking attachment molded into the housing. So I had to get Cuddeback metal housing. And I'm glad I bought the Cuddesafe metal housings. They mount with 2 drywall screws to the tree and I use a cable lock system to secure it to the tree. I never had a problem of thefts on my farm but at a total cost of almost $200 per camera I wanted to be secure. I installed 5 cameras around the farm with the home camera in my back yard for easy memory chip removal to check the other 4 cameras. #1 home camera in my back yard. #2 camera is down the hill about 150 yds from #1 with a service level of 68. #3 camera is across my food plot about 200 yds from #2 and service level of 94. #4 camera is up hill in my woods about 200 yds from #3 and service is 34. But quality of pictures is great back to home camera. #5 camera is about 200 yds from the #1 home camera on the other side of the farm with service of 78. I got 158 pictures on #2-3-4 cameras but none on #5 which is on a little used trail. This was on the 1st day and 2 nights. But about 20 pictures were of me setting the cameras up. Picture quality was excellent for day and night pictures and detection distant length seems OK. The Cuddelink report that's available off the home memory chip is a good review of all 5 cameras results of battery level, number pictures taken, and the service level between cameras. So far after only 1 day I'm impressed with the system. But time will tell after several months of use. I'll do updates as time requires.
